-8. **create_memory_project** - Essential for project setup
-9. **move_note** - Knowledge organization
-10. **delete_project** - Project lifecycle management

-12. **read_content** - Raw content access
-13. **delete_note** - Content removal
-14. **list_directory** - File system exploration

+16. **bm_man** — manual index, page lookup, and text search
 
 ### **Tier 4: Specialized (Rarely Test)**
-17. **MCP Prompts** - Enhanced UX tools (ai_assistant_guide, continue_conversation)
-
-## Stateless Architecture Testing
-
-### **Project Discovery Workflow**
-Test project selection:
-
-1. **Initial Discovery**
-   - Call `list_memory_projects()` without knowing which project to use
-   - Verify the footer explains routing: pass a project name (or `[external_id]` as `project_id`); calls without one use the session's active project, then the configured default
-   - Confirm no scripted "ask the user" lines and no CLI-specific references
-
-2. **Activity-Based Discovery**
-   - Call `recent_activity()` without project parameter (discovery mode)
-   - Verify the summary names the most active project: `Suggested project: '<name>' (most active with N items)`
-   - With no activity anywhere, verify it reports "No recent activity found in any project." and adds no scripted question
-
-3. **Session Tracking Validation**
-   - Verify tool responses include `[Session: Using project 'name']`
-
-4. **Single Project Constraint Mode**
-   - Test MCP server with `--project` parameter
-   - Verify all operations constrained to specified project
-   - Test project override behavior in constrained mode
-
-### **Explicit Project Parameters**
-All tools must require explicit project parameters:
-
-1. **Parameter Validation**
-   - Test all Tier 1 tools require `project` parameter
-   - Verify clear error messages for missing project
-   - Test invalid project name handling
-
-2. **No Session State Dependencies**
-   - Confirm no tool relies on "current project" concept
-   - Test rapid project switching within conversation
-   - Verify each call is truly independent
+17. **MCP prompts and resources** — assistant guide, conversation continuity, manual pages
+
+## Project Routing Tests
+
+1. Call `bm_project(command="list")`; inspect project names, external IDs, and
+   workspace grouping. Reuse a returned UUID through `project`.
+2. Call `bm_project(command="recent", project=<test-project>, since="7d")`.
+   Check paging and indexing guidance. Without `project`, it uses the default
+   project; with no default, it aggregates projects. Empty activity is not proof
+   of an empty knowledge base.
+3. Test explicit names, workspace-qualified names, UUIDs, and project-qualified
+   paths. A path prefix and explicit project must agree. Verify ambiguous and
+   conflicting routes fail clearly.
+4. Test a server constrained with `--project`. Verify operations cannot bypass
+   that constraint.
+5. Switch between two disposable projects with the same note title. Confirm reads
+   and writes stay in the requested project and do not depend on an earlier call.
+6. Test omission according to each tool's schema, including default-project use
+   and ambiguous unqualified note refusals. Do not expect every tool to require
+   `project` or to emit a session-tracking footer.

-## DESCRIPTION
-
-Returns the full markdown of one note with knowledge-graph context. The
-identifier resolves fuzzily: an exact permalink wins, then title match.
-For in-place changes use edit-note(3); for discovery use search-notes(3).

-An AGENT-IN-THE-LOOP run kind: the same model, budget, task set, and seeded

-tools) vs `posix` (the `cat`/`grep`/`ls`/`find`/`tail`/`man` read surface from

-against an ephemeral per-surface `bm mcp` stdio instance, feeds results back,
-and grades the final answer plus the resulting project state.
+The agent loop uses the `bm` surface declared in `agent_tasks/surfaces.py`:

+the harness dispatches them to an isolated MCP server and grades the final
+answer and resulting project state.

+The old `rich` and `posix` presets are retired. Historical artifacts retain
+those labels and their original tool schemas; rerun with `bm` to establish a
+1.0 baseline. Do not relabel old results as new-tool measurements.

+# Basic Memory 1.0 working migration guide
+
+This is the working change list and migration guide for 1.0. It covers the new
+tool contracts and the corresponding changes to agents, integrations, tests, and
+documentation. Add migration decisions and verified instructions as release work lands.
+Each section distinguishes implemented development work from planned release work;
+neither implies that the current published release includes the change.
+
+## Cloud transfers: replace sync and bisync with push/pull
+
+**Status:** planned for v1.0; implementation tracked in
+[#1845](https://github.com/basicmachines-co/basic-memory/issues/1845).
+This completes the deprecation introduced through
+[#1596](https://github.com/basicmachines-co/basic-memory/issues/1596).
+
+### What is being removed
+
+- `bm cloud sync`: destructive one-way mirroring from local files to Cloud.
+- `bm cloud bisync`: bidirectional mirroring.
+- `bm cloud bisync-reset`: initialization/reset of bisync state.
+
+The plan is to retain migration-only stubs for these command names in 1.0. They will
+exit nonzero with replacement instructions and perform no transfers or deletions.
+They will not silently invoke push or pull.
+
+### Why
+
+Cloud notes can be created and edited by people and managed agents independently of
+your local folder. The old `sync` command makes Cloud match that folder, deleting
+cloud-only files and files excluded by the local `.bmignore`. A local copy should
+not silently erase knowledge created in Cloud.
+
+Push/pull provide explicit directional transfers on both Personal and Team
+workspaces. They preserve files found only on the destination and surface differing
+content for an explicit choice.
+
+### Replacement commands
+
+Download Cloud files into the configured local folder:
+
+```bash
+bm cloud pull --name research --dry-run
+bm cloud pull --name research
+```
+
+Upload local files to Cloud:
+
+```bash
+bm cloud push --name research --dry-run
+bm cloud push --name research
+```
+
+Use `--workspace <workspace-slug>` when the project name is ambiguous. Existing
+local path configuration remains useful. `bm cloud sync-setup` is not being removed
+by this change: it configures that path, rather than running the legacy mirror.
+Personal transfers still use shared rclone setup; Team transfers use WebDAV with
+project-level authorization and do not require rclone setup.
+
+### Resolve differing files explicitly
+
+By default, a transfer aborts before copying anything if it finds conflicting files
+or cannot compare files. It lists conflicts so you can inspect them and choose:
+
+| Option | On push | On pull |
+| --- | --- | --- |
+| `--on-conflict fail` (default) | Abort on differing files | Abort on differing files |
+| `--on-conflict keep-local` | Replace differing Cloud files with local content | Leave differing local files untouched |
+| `--on-conflict keep-cloud` | Leave differing Cloud files untouched | Replace differing local files with Cloud content |
+| `--on-conflict keep-both` | Save incoming local content as a conflict copy in Cloud | Save incoming Cloud content as a conflict copy locally |
+
+These choices apply to differing files; new source files are still transferred.
+Conflict copies use a `.conflict-<date>` suffix before the file extension.
+
+For an intentional local-authoritative upload, preview first:
+
+```bash
+bm cloud push --name research --on-conflict keep-local --dry-run
+bm cloud push --name research --on-conflict keep-local
+```
+
+This preserves cloud-only files. It is **not** an exact-mirror replacement for
+`cloud sync`.
+
+To download and preserve both versions of differing files:
+
+```bash
+bm cloud pull --name research --on-conflict keep-both --dry-run
+bm cloud pull --name research --on-conflict keep-both
+```
+
+### Important differences from mirroring
+
+- **Deletions do not propagate.** Deleting a local file does not delete its Cloud
+  copy; deleting a Cloud file does not delete its local copy. A later transfer in
+  the reverse direction can copy that file back.
+- **Renames are not tracked as moves.** The new path may transfer while the old
+  destination path remains. Review and remove obsolete copies explicitly.
+- **There is no shared sync baseline.** Any differing content is a conflict, even
+  when only one side was edited. These commands do not perform Git-style
+  three-way merges or automatically choose the newest version.
+- **Pull followed by push is not bidirectional mirroring.** It does not propagate
+  deletions or resolve divergent content automatically.
+- **Ignore rules do not clean up previous uploads.** For Personal workspaces,
+  `bm cloud prune --name research --dry-run` previews Cloud files matching local
+  `.bmignore` rules. Running it without `--dry-run` requests confirmation before
+  deletion. This is targeted cleanup, not general mirror deletion.
+
+### Updating scripts and scheduled jobs
+
+1. Find calls to `cloud sync`, `cloud bisync`, and `cloud bisync-reset` in scripts,
+   scheduled tasks, and personal instructions.
+2. Choose the intended direction: push for uploads, pull for downloads. If both
+   are needed, account explicitly for conflicts and the lack of deletion tracking.
+3. Preview with `--dry-run`. With conflicts, select a strategy before previewing
+   the resolved transfer; dry-run does not bypass conflict checks.
+4. Use the default conflict failure unless the workflow deliberately chooses a
+   winning side. Monitor nonzero exits rather than silently discarding them.
+5. Handle intentional deletion or rename cleanup separately, after reviewing the
+   affected files. Do not assume a missing local file authorizes Cloud deletion.
+
+The removal must not automatically delete local files, Cloud files, credentials,
+or old bisync state directories. Existing backups and snapshots remain independent
+of transfer commands. Removing `cloud check` is outside this migration's scope.
+
+### Release checklist
+
+- [ ] Land #1845 and verify the migration-only command errors.
+- [ ] Verify examples against the 1.0 CLI on Personal and Team workspaces.
+- [ ] Update CLI help, manuals, setup output, and public Cloud transfer guides.
+- [ ] Include the removal and behavioral differences in release/upgrade notes.
+- [ ] Confirm no active documentation recommends sync or bisync as a transfer workflow.

+## MCP tools: migrate to the bm_* surface
+
+**Status:** implemented on the development branch for 1.0 (SPEC-35.2). Upgrade your
+server and its agent packages together, then restart clients to refresh cached tool
+schemas and permission lists. This does not rename the CLI's `bm tool` commands.
+
+| Previous MCP tool | 1.0 replacement |
+| --- | --- |
+| `read_note`, `read_content`, `view_note`, `cat`, bounded reads using `tail` | `bm_read` with explicit line bounds where needed |
+| `write_note` | `bm_write` |
+| `edit_note` | `bm_edit` |
+| `search_notes`, `grep` | `bm_search` |
+| `build_context` | `bm_context` |
+| `list_directory`, `ls` | `bm_list` for one level; `bm_find` for recursive inventory |
+| `find` | `bm_find` |
+| `recent_activity` | `bm_project(command="recent")` |
+| `list_memory_projects`, `list_workspaces` | `bm_project(command="list")` |
+| `create_memory_project` | `bm_project(command="create", name=..., path=...)` |
+| `delete_project` | `bm_project_delete` (opt-in) |
+| `schema_validate`, `schema_infer`, `schema_diff` | `bm_schema(command="validate"/"infer"/"diff")` |
+| `move_note` | `bm_move` |
+| `delete_note` | `bm_delete` |
+| `man` | `bm_man` |
+
+### Tool-by-tool change list
+
+The primary surface has twelve tools, plus the separately enabled destructive
+`bm_project_delete` operation. The registry in
+`src/basic_memory/mcp/tools/__init__.py` and installed manuals are authoritative.
+
+| Tool | Capabilities and migration details |
+| --- | --- |
+| `bm_read` | Exact note/file reads, with line, section, and token-budget bounds. Missing targets are refusals; callers must search separately instead of relying on fuzzy read fallback. JSON includes revision metadata. |
+| `bm_write` | Create notes or explicitly overwrite an existing target. Guard overwrites with `expected_checksum`; consume the compact change receipt. |
+| `bm_edit` | Incremental edits and frontmatter changes selected by `command`. A missing note is refused, not created. |
+| `bm_delete` | Delete a note through `identifier`, or a directory through `path` with `recursive=True`. Remove the old `is_directory` argument; locked-note protection still applies. |
+| `bm_move` | Move a note or directory to `destination`. A trailing slash means move into that directory under the source's existing name; without it, the destination is the new path. |
+| `bm_search` | Ranked text, title, permalink, semantic, or hybrid search; metadata filters; project scopes; and matching-line searches. Replaces both note search and the MCP grep workflow. |
+| `bm_context` | Build graph context from an exact `identifier`, with bounded depth and time window. Whitespace-only identifiers are refused. |
+| `bm_list` | List one directory level. Root discovery exposes addressable project mounts; use returned scope for follow-up calls. |
+| `bm_find` | Recursive file discovery with path and frontmatter filters. Use this for inventory rather than expecting recursive `bm_list` results. |
+| `bm_project` | Consolidate `list`, `create`, and `recent`. Project rows carry workspace metadata; deletion is not a command on this tool. |
+| `bm_project_delete` | Separate, opt-in destructive project deletion. Keep it separate in tool permissions and agent allowlists. |
+| `bm_schema` | Consolidate schema `validate`, `infer`, and `diff` behind `command`. |
+| `bm_man` | Discover, read, or search installed manuals. Supply a page or a query, not both; no project selection is required. |
+
+### Change arguments and response handling too
+
+- Pass names, workspace-qualified names, or external UUIDs through `project`.
+  Remove `project_id`; calls do not retain a selected project between requests.
+- Search uses `mode`, `filters`, `items`, `since`, and `all_projects` instead of
+  `search_type`, `metadata_filters`, `entity_types`, `after_date`, and
+  `search_all_projects`. Use `items=["note"]` for whole notes. Put `tags` and
+  `status` inside `filters`; `note_types` still filters frontmatter types.
+- Edit uses `command` instead of `operation`. `set_metadata` edits frontmatter;
+  edits never create missing notes.
+- Context uses `identifier` instead of `url` and `since` instead of `timeframe`.
+  It defaults to JSON and a seven-day window. Depth is bounded to 1–5.
+- Recent activity uses `command="recent"` and `since`. JSON returns an object
+  with `results` and paging fields, rather than a bare array.
+- Project discovery returns project rows with workspace fields. It does not return
+  the old standalone workspace role/subscription response.
+- Reads use `start_line`, `end_line`, `section`, or `max_tokens`; `page` and
+  `page_size` do not slice note content. JSON reads include frontmatter by default;
+  pass `include_frontmatter=False` when a consumer needs the body alone.
+- Move uses `destination`. End a folder destination with `/` to preserve the file
+  name. JSON move/delete receipts identify success through `action` (`moved` or
+  `deleted`), rather than boolean `moved`/`deleted` fields.
+- Refusals set MCP `isError`. JSON error text contains `error`, `message`, and
+  sometimes `try_instead`. Handle `NOT_FOUND`, `ALREADY_EXISTS`, and
+  `REVISION_CONFLICT`; do not treat them as successful empty results or expect
+  legacy `NOTE_*` payload fields. Read again to obtain the current checksum.
+
+For an overwrite, prefer the exact returned `file_path` as `identifier` and pass
+`expected_checksum` from a fresh read. Do not reconstruct a filename from a title.
+
+```python
+note = await bm_read(identifier="notes/Plan.md", project="research", output_format="json")
+await bm_write(
+    identifier=note["file_path"],
+    content="Updated plan.",
+    overwrite=True,
+    expected_checksum=note["checksum"],
+    project="research",
+)
+await bm_search(filters={"status": "active", "tags": ["planning"]}, project="research")
+await bm_project(command="recent", since="7d", project="research", output_format="json")
+```
+
+### Update callers and installed instructions
+
+Update custom agents, hooks, MCP allowlists, tool routers, recorded request fixtures,
+and test fakes as well as prompts and skills. Native Hermes and OpenClaw wrappers
+may retain their host-facing arguments while translating to the new MCP contract.
+Tau preserves the core `bm_` prefix; there is no `bm_bm_write` tool.
+
+Use `bm_man(page="bm-search(3)")` or `bm man bm-search` for the installed reference.
+Re-run benchmark baselines after upgrading; historical results describe the tool
+surface they were measured against and should not be relabeled as 1.0 results.
+
+### Project routing and refusal handling
+
+- With multiple addressable projects, core note/search calls require an explicit
+  `project` or a recognized project-qualified target, even if a default project
+  is configured. A single-project constraint can supply the scope implicitly.
+- A relative path such as `notes/topic.md` does not select a project merely
+  because it contains a slash. Use returned qualified identifiers or pass scope.
+- Search resolves project-qualified `memory://` URLs without rewriting stored
+  project-qualified permalinks into workspace-qualified identities.
+- Native ChatGPT search/fetch and saved search/continue prompts resolve their
+  selected/default project before calling the stricter core tools. Qualified
+  fetch targets still select the project they name.
+- Mutation receipts replace prose/footer parsing. Use `action`, `file_path`,
+  `permalink`, and `checksum` where returned; moves include `previous_file_path`.
+- Handle `LOCKED`, `INVALID_ARGUMENTS`, `OUTSIDE_PROJECT`, and other typed
+  refusals as errors. An absent checksum does not prove a note was deleted.
+  For `OUTCOME_UNKNOWN`, read back the target before retrying a mutation.
+
+## Agent instructions, prompts, and packages
+
+**Status:** migrated in the development branch as part of
+[Core PR #1849](https://github.com/basicmachines-co/basic-memory/pull/1849).
+
+- Updated canonical `skills/memory-*`, onboarding references, skill indexes,
+  and the shared skill-bundle source to the new names, arguments, and receipts.
+- Updated Claude Code and Codex harness skills, Claude output style, setup
+  examples, and shared schema examples, including the synchronized Tau copies.
+- Refreshed Pi's generated skill references and their generation input; updated
+  Hermes's bundled skill and Tau's setup skill.
+- Updated MCP server instructions, the assistant-guide resource, and the extended
+  assistant guide so agents are taught the same contracts the server exposes.
+- Migrated the search, recent-activity, continue-conversation, and getting-started
+  prompts. Search and continue propagate project scope and MCP context to tools.
+- Updated package validators and assertions to check the migrated instructions.
+
+## Runtime integrations and compatibility
+
+**Status:** adapters migrated and review fixes included in Core PR #1849.
+
+- **Hermes:** outbound MCP calls and response handling use the new tools while
+  preserving the host-native memory-provider interface.
+- **OpenClaw:** the client translates native wrapper arguments to the new MCP
+  contracts and preserves structured refusal messages. Workspace discovery
+  deduplicates workspace metadata from project rows; it does not invent the old
+  workspace role/subscription fields. Overwrite guidance documents checksum guards.
+- **Tau:** preserves existing `bm_` names instead of adding a second prefix.
+  When legacy aliases and native tools collide, native registrations win
+  regardless of discovery order; noncolliding extras remain available.
+- **ChatGPT:** native `search` and `fetch` remain available and delegate to the
+  new core tools, preserving default-project behavior and qualified target routing.
+- **Legacy view wrapper:** `view_note` delegates to `bm_read`.
+- Removed the unused, disabled MCP UI SDK implementation and its obsolete tests.
+  This does not remove the separately supported hosted MCP App interface.
+
+The legacy core registry is **not removed by this migration**. Old tools remain
+registered alongside the new surface until the coordinated retirement tracked in
+[#1833](https://github.com/basicmachines-co/basic-memory/issues/1833).
+Their manual pages are marked as compatibility documentation. Diagnostics,
+native host wrapper names, CLI command names, and separately advertised hosted
+Cloud review/App APIs retain their own contracts.
+
+## Tests and benchmark migration
+
+**Status:** callers and assertions migrated; fresh model-driven benchmark results
+remain a release follow-up.
+
+- Migrated integration-test MCP calls, dynamic helpers, and fixtures to `bm_*`.
+  Assertions check actual new receipts and refusals rather than a legacy adapter.
+- Preserved coverage for checksum conflicts, concurrent writes, locked notes,
+  path safety, directory operations, metadata identity, search, and workspace routing.
+- Added real MCP regressions for saved-prompt default/explicit project routing
+  and ChatGPT relative/qualified fetch identifiers with multiple projects.
+- Added Tau registration tests for both legacy/native discovery orders, checking
+  native schemas, actual dispatch, and preservation of noncolliding extras.
+- Updated OpenClaw's real filesystem tests to wait for bounded asynchronous file
+  materialization rather than treating an immediately stale projection as failure.
+- Replaced benchmark rich/POSIX surface comparisons with one canonical `bm`
+  surface. Read-only scenarios filter mutation tools from that surface.
+- Migrated benchmark providers, load/concurrent-write runners, task graders,
+  scripted smoke inputs, and the bundled read/edit/search manual corpus.
+- Retained clean-checkout benchmark provenance checks and historical result
+  artifacts. Old results require their matching runner revision for reproduction.
+
+Migration verification included core SQLite and PostgreSQL CI, static checks,
+package checks, adapter regressions, the benchmark unit suite, and a successful
+scripted agent-task smoke run. Paid/model-driven benchmark baselines have not
+been rerun; a scripted smoke result is not a performance comparison.
+
+## Documentation and historical cleanup
+
+**Status:** current repository docs migrated in Core PR #1849; public-site changes
+are in [Docs PR #52](https://github.com/basicmachines-co/docs.basicmemory.com/pull/52).
+
+- Updated README, architecture, search, manual, plugin, and live-test guidance,
+  including hidden Claude commands that generate or exercise tool calls.
+- Aligned bundled tool manuals with explicit project routing and labeled legacy
+  manual pages as compatibility references.
+- Updated the docs site's MCP reference, migration guide, current user/setup
+  guides, navigation examples, saved prompts, and error/retry guidance.
+- Labeled upcoming 1.0 guidance without rewriting the published 0.24 release
+  history or implying that the site changes deploy the server.
+- Moved `post-v0.18.0-test-plan.md` and `mcp-ui-bakeoff-instructions.md` into
+  `docs/archive/` with historical banners. Kept release notes, changelogs, and
+  benchmark results as records of the versions they actually describe.
+
+## Remaining 1.0 release work
+
+- [ ] Land the core and docs-site migration PRs and publish the updated packages/docs.
+- [ ] Complete coordinated legacy tool retirement in #1833 and refresh the final
+  advertised tool inventory and compatibility manuals.
+- [ ] Rerun model-driven benchmarks against the new tool surface and record fresh
+  baselines with exact code/model provenance.
+- [ ] Complete the cloud-transfer removal and verification checklist above (#1845).
+- [ ] Verify released server/package combinations, client schema refresh, and
+  permission/allowlist migration; include the breaking changes in release notes.

+Basic Memory is a persistent Markdown knowledge base shared by humans and their AI
+assistants. This guide describes the 1.0 MCP surface. The installed tool schemas and
+`bm_man` pages are authoritative for exact signatures. CLI commands retain their
+shell names; host integrations may expose their own native wrappers.
 
 ## Understanding Basic Memory
 
-**Core Concept**: Basic Memory is a local-first knowledge management system that creates a semantic knowledge graph from markdown files. It enables persistent, structured knowledge that survives across AI sessions.
-
-### Key Principles
-
-**Local-First Architecture**
-- All knowledge stored as plain text markdown files on user's computer
-- SQLite database indexes files for fast search and navigation
-- Files are the source of truth, database is derived state
-- User maintains complete control over their data
-
-**Semantic Knowledge Graph**
-- Entities: Individual markdown files representing concepts
-- Observations: Categorized facts with optional tags
-- Relations: Directional links between entities
-- Graph traversal enables context building and exploration
-
-**Persistent Context**
-- Knowledge persists across conversations
-- AI can reference previous discussions
-- Context builds over time through accumulated knowledge
-- Enables long-term collaborative development
-
-### AI as Knowledge Collaborator
-
-Basic Memory's semantic knowledge graph - observations, relations, context building - is designed to help you (the AI assistant) provide better help to humans. You use the graph structure to:
-- Build relevant context from past conversations
-- Navigate connections between ideas
-- Understand relationships and dependencies
-- Provide continuity across sessions
+A **project** is the isolation boundary for notes, graph state, and search. A **note**
+is the canonical Markdown document; its indexed **entity** connects observations
+and relations to search and graph traversal. Local projects keep files on disk;
+Cloud projects provide hosted storage. Indexing makes edits available for retrieval.
 
-**The distinction**: You're helping humans build enduring knowledge they'll own forever, not creating disposable agent memory. The better you use these tools, the more valuable their knowledge becomes over time. Think of markdown files as artifacts that will outlast any particular AI model - your job is to help create knowledge worth keeping.
-
-### Architecture Overview
-
-```
-User's Markdown Files (Source of Truth)
-         ↓
-    File Sync
-         ↓
-SQLite Database (Index)
-         ↓
-    MCP Server
-         ↓
-   AI Assistant
-```
-
-**Data Flow**:
-1. User creates/edits markdown files
-2. Sync process detects changes
-3. Files are parsed and indexed in SQLite
-4. MCP server exposes indexed data to AI
-5. AI can query, traverse, and update knowledge graph
----
+Use memory for decisions, discoveries, plans, preferences, and reference material
+that should survive a conversation. Search before creating, read before editing,
+and preserve the user's project choice across calls. Follow the user's existing
+capture authorization; ask before saving when no authorization exists.
 
 ## Project Management
 
-**Project Concept**: A project is a directory of markdown files with its own knowledge graph. Users can have multiple independent projects.
-
-### Discovering Projects
-
-**Always start by discovering available projects:**
-
-```python
-# List all projects
-projects = await list_memory_projects()
-
-# Response structure (each entry includes external_id you can pass as project_id):
-# [
-#   {
-#     "name": "main",
-#     "external_id": "550e8400-e29b-41d4-a716-446655440000",
-#     "path": "/Users/name/notes",
-#     "is_default": True,
-#     "note_count": 156,
-#     "last_synced": "2025-01-15T10:30:00Z"
-#   },
-#   {
-#     "name": "work",
-#     "external_id": "9f86d081-884c-42a3-b5e3-1c0c5b4c8e52",
-#     "path": "/Users/name/work-notes",
-#     "is_default": False,
-#     "note_count": 89,
-#     "last_synced": "2025-01-14T16:45:00Z"
-#   }
-# ]
-```
-
-**When to discover projects**:
-- Start of conversation when project unknown
-- User asks about available projects
-- Before any operation requiring project selection
-- After errors related to project not found
-
-### Project Selection Patterns
-
-**Single-Project Users**:
-
-```python
-# Enable default_project_mode in config
-# ~/.basic-memory/config.json
-{
-  "default_project": "main",
-  "default_project_mode": true
-}
-
-# Then tools work without project parameter
-await write_note("Note", "Content", "folder")
-await search_notes(query="test")
-```
-
-**Multi-Project Users**:
-
-```python
-# Keep default_project_mode disabled (default)
-# Always specify project explicitly
-
-# All tool calls require project
-await write_note("Note", "Content", "folder", project="main")
-await search_notes(query="test", project="work")
-
-# Can target different projects in same conversation
-results_main = await search_notes(query="auth", project="main")
-results_work = await search_notes(query="auth", project="work")
-```
-
-**Recommended Workflow**:
+Discover projects when the route is unknown or the user asks for their projects:
 
 ```python
-# 1. Discover projects
-projects = await list_memory_projects()
-
-# 2. Ask user which to use (if ambiguous)
-# "I found 2 projects: 'main' and 'work'. Which should I use?"
-
-# 3. Store choice for session
-active_project = "main"
-
-# 4. Use in all subsequent calls
-results = await search_notes(query="topic", project=active_project)
-```
-
-### `project` vs `project_id`
-
-Every project has two identifiers:
-
-- **`project`** — human-readable name (e.g., `"main"`). Easy to use, but can collide across cloud workspaces.
-- **`project_id`** — stable `external_id` UUID. Always unambiguous; takes precedence over `project` when both are passed.
-
-**When to prefer `project_id`:**
-
-1. **Cloud multi-workspace setups.** If the user belongs to more than one workspace (personal + organization, or several organizations) and the same project name might exist in more than one of them, pass `project_id` to route to the exact project. Without it, name resolution falls back to the default workspace, which may not be the one the user means.
-2. **After `list_memory_projects()`.** Once you have the `external_id`, prefer using it — it's the same number of characters in JSON and saves a name-resolution round-trip.
-3. **When persisting a project choice across a long session.** UUIDs are stable; names can be renamed.
-
-**When `project` (name) is fine:**
-
-- Local single-workspace setups (no collision risk).
-- One-off operations where the name is clearly visible to the user (e.g., quick `search_notes(project="main", ...)`).
-- The user explicitly references a project by name in their message.
-
-**Example — cloud multi-workspace pattern:**
-
-```python
-# Discover and pick the right project for this user
-projects = await list_memory_projects()
-target = next(p for p in projects if p["name"] == "research" and p["workspace"]["slug"] == "acme")
-
-# Use the UUID for all subsequent operations — no ambiguity
-await write_note(
-    title="Meeting Notes",
-    content="...",
-    folder="meetings",
-    project_id=target["external_id"],
-)
-results = await search_notes(query="kickoff", project_id=target["external_id"])
+await bm_project(command="list", output_format="json")
 ```
 
-**Precedence rule:** When both are passed, `project_id` wins. This lets you safely supply `project="main"` for backward compatibility while still routing precisely with `project_id`.
-
-### Cross-Project Operations
-
-**Some tools work across all projects when project parameter omitted:**
+Pass a project name, `workspace/project`, or a returned `external_id` UUID through
+one parameter: `project`. Use a qualified name or UUID when names collide across
+Cloud workspaces. A project-qualified file path also routes a call; an explicit
+`project` must agree with that prefix. Do not assume that a previous call selected
+a project for later calls. Note-addressing tools can refuse unqualified identifiers
+when several projects are available, even if a default is configured.
 
 ```python
-# Recent activity across all projects
-activity = await recent_activity(timeframe="7d")
-# Returns activity from all projects
-
-# Recent activity for specific project
-activity = await recent_activity(timeframe="7d", project="main")
-# Returns activity only from "main" project
+await bm_project(command="recent", since="7d", project="main")
+await bm_search(query="authentication", project="main")
+await bm_read(identifier="specs/authentication.md", project="main")
 ```
 
-**Tools supporting cross-project mode**:
-- `recent_activity()` - aggregate activity across projects
-- `list_memory_projects()` - always returns all projects
-- `sync_status()` - can show all projects or specific
+For `command="recent"`, omitting `project` uses the default project; only when no
+default exists does it aggregate projects. No recent activity does not establish
+that a project is empty. Check indexing guidance and search before drawing that
+conclusion. The CLI `bm status` reports local indexing status; there is no MCP
+`sync_status` tool.
 
-### Creating Projects
-
-**Create new projects programmatically:**
+Create a project when requested:
 
 ```python
-# Create new project
-await create_memory_project(
-    project_name="research",
-    project_path="/Users/name/Documents/research",
-    set_default=False
-)
-
-# Create and set as default
-await create_memory_project(
-    project_name="primary",
-    project_path="/Users/name/notes",
-    set_default=True
+await bm_project(
+    command="create",
+    name="research",
+    path="/Users/name/Documents/research",
+    set_default=False,
 )
 ```
 
-**Use cases**:
-- User requests new knowledge base
-- Separating work/personal notes
-- Project-specific documentation
-- Client-specific knowledge
-
-### Project Status
-
-**Check sync status before operations:**
-
-```python
-# Check if sync complete
-status = await sync_status(project="main")
-
-# Response indicates:
-# - sync_in_progress: bool
-# - files_processed: int
-# - files_remaining: int
-# - last_sync: datetime
-# - errors: list
-
-# Wait for sync if needed
-if status["sync_in_progress"]:
-    # Inform user: "Sync in progress, please wait..."
-    # Or proceed with available data
-```

+Project deletion is a separate `bm_project_delete` tool, available only when enabled
+by the server. Read its manual before using it; Cloud deletion removes note files.
 
 ## Knowledge Graph Fundamentals
 
-**The knowledge graph is built from three core elements: entities, observations, and relations.**
-
-### Entities
-
-**What is an Entity?**
-- Any concept, document, or idea represented as a markdown file
-- Has a unique title and permalink
-- Contains frontmatter metadata
-- Includes observations and relations
-
-**Entity Structure**:
+Write categorized observations and typed WikiLinks where they improve recall:
 
 ```markdown

-title: Authentication System
-permalink: authentication-system
-tags: [security, auth, api]
-type: note
-created: 2025-01-10T14:30:00Z
-updated: 2025-01-15T09:15:00Z
+title: Authentication Design
+type: spec

-
-## Observations

-
-**Entity Types**:
-- `note`: General knowledge (default)
-- `person`: People and contacts
-- `project`: Projects and initiatives
-- `meeting`: Meeting notes
-- `decision`: Documented decisions
-- `spec`: Technical specifications
-
-### Observations
-
-**Observations are categorized facts with optional tags.**
-
-**Syntax**: `- [category] content #tag1 #tag2`
+The API needs a consistent authentication policy.
 
-**Common Categories**:
-- `[fact]`: Objective information
-- `[idea]`: Thoughts and concepts
-- `[decision]`: Choices made
-- `[technique]`: Methods and approaches
-- `[requirement]`: Needs and constraints
-- `[question]`: Open questions
-- `[insight]`: Key realizations
-- `[problem]`: Issues identified
-- `[solution]`: Resolutions
-
-**Examples**:
-
-```markdown
 ## Observations
-- [decision] Use JWT tokens for authentication #security
-- [technique] Hash passwords with bcrypt before storage #best-practice
-- [requirement] Support OAuth 2.0 providers (Google, GitHub) #auth
-- [fact] Session timeout set to 24 hours #configuration
-- [problem] Password reset emails sometimes delayed #bug
-- [solution] Implemented retry queue for email delivery #fix
-- [insight] 2FA adoption increased security by 40% #metrics
-```
-
-**Why Categorize?**:
-- Enables semantic search by observation type
-- Helps AI understand context and intent
-- Makes knowledge more queryable
-- Provides structure for analysis
-
-### Relations
-
-**Relations are directional links between entities.**
-
-**Syntax**: `- relation_type [[Target Entity]]`
-
-**Common Relation Types**:
-- `relates_to`: General connection
-- `implements`: Implementation of spec/design
-- `requires`: Dependency relationship
-- `extends`: Extension or enhancement
-- `part_of`: Hierarchical membership
-- `contrasts_with`: Opposite or alternative
-- `caused_by`: Causal relationship
-- `leads_to`: Sequential relationship
-- `similar_to`: Similarity relationship
-
-**Examples**:
-
-```markdown
-## Relations
-- implements [[Authentication Spec v2]]
-- requires [[User Database Schema]]
-- extends [[Base Security Model]]
-- part_of [[API Backend Services]]
-- contrasts_with [[API Key Authentication]]
-- leads_to [[Session Management]]
-```
-
-**Bidirectional Links**:
-
-```markdown
-# In "Login Flow" note
-## Relations
-- part_of [[Authentication System]]
-
-# In "Authentication System" note
-## Relations
-- includes [[Login Flow]]
-```
-
-**Why explicit relation types matter**:
-- Enables semantic graph traversal
-- AI can understand relationship meaning
-- Supports sophisticated context building
-- Makes knowledge more navigable
-
-### Forward References
-
-**You can reference entities that don't exist yet:**
-
-```python
-# Create note referencing non-existent entity
-await write_note(
-    title="API Implementation",
-    content="""# API Implementation
+- [decision] Use short-lived access tokens #security
+- [requirement] Support token revocation
+- [question] Which clients need offline access?
 
 ## Relations
-- implements [[API Specification]]
-- requires [[Database Models]]
-""",
-    folder="api",
-    project="main"
-)
-# Creates forward references to "API Specification" and "Database Models"
-
-# Later, create referenced entities
-await write_note(
-    title="API Specification",
-    content="# API Specification\n...",
-    folder="specs",
-    project="main"
-)
-# Forward reference automatically resolved!
-
-await write_note(
-    title="Database Models",
-    content="# Database Models\n...",
-    folder="database",
-    project="main"
-)
-# Second forward reference resolved!
+- implements [[Security Requirements]]
+- requires [[User Database]]
 ```
 
-**How it works**:
-1. Forward reference creates placeholder in knowledge graph
-2. When target entity is created, relation is automatically resolved
-3. Graph traversal works in both directions
-4. No manual linking required
-
-**Use cases**:
-- Planning features before implementation
-- Creating outlines with linked topics
-- Bottom-up knowledge building
-- Incremental documentation
-
----
+Observations use `- [category] content`; relations use `- relation_type [[Target]]`.
+Prefer specific facts, meaningful categories, and exact target titles or identifiers.
+Forward references can resolve when their targets are later indexed. Do not invent
+facts or add observations and links merely to meet a quota.
 
 ## Writing Knowledge
 
-**Creating rich, well-structured notes is fundamental to building a useful knowledge graph.**
-
-### Basic Note Creation
-
-**Minimal note**:
+Create with an explicit file path, or with `title` and `directory`:
 
 ```python
-await write_note(
-    title="Quick Note",
-    content="# Quick Note\n\nSome basic content.",
-    folder="notes",
-    project="main"
+await bm_write(
+    identifier="decisions/authentication.md",
+    title="Authentication Decision",
+    content="# Authentication Decision\n\n## Observations\n- [decision] Use short-lived tokens",
+    note_type="decision",
+    metadata={"status": "open"},
+    tags=["auth", "security"],
+    overwrite=False,
+    project="main",
 )
 ```
 
-> **Important**: `write_note` errors if the note already exists. Use `edit_note` for incremental changes, or pass `overwrite=True` to replace.
-
-**Well-structured note**:
-
 ```python
-await write_note(
-    title="Database Design Decisions",
-    content="""# Database Design Decisions
-
-## Context
-Documenting our database architecture choices for the authentication system.
-
-## Observations

-- [requirement] Must support multi-tenant data isolation #security
-- [fact] Expected load is 10K requests/minute #performance
-- [insight] UUID keys enable easier horizontal scaling #scalability

-## Relations

-    folder="architecture",
-    tags=["database", "design", "authentication"],
-    project="main"

+    title="API Review",
+    directory="meetings",
+    content="# API Review\n\n## Decisions\nReview the token lifecycle next week.",
+    project="main",
 )
 ```
 
-### Effective Observation Writing
-
-**Good observations are**:
-- **Specific**: Avoid vague statements
-- **Categorized**: Use appropriate category
-- **Tagged**: Add relevant tags
-- **Atomic**: One fact per observation
-- **Contextual**: Include enough detail
-
-**Examples**:
-
-**❌ Poor observations**:
-```markdown
-- [fact] We use a database
-- [idea] Security is important
-- [decision] Made some changes
-```
-
-**✓ Good observations**:
-```markdown
-- [fact] PostgreSQL 14 database runs on AWS RDS with 16GB RAM #infrastructure
-- [decision] Implemented rate limiting at 100 requests/minute per user #security
-- [technique] Using bcrypt with cost factor 12 for password hashing #cryptography
-```
-
-### Writing Effective Relations
-
-**Relations should be**:
-- **Directional**: Clear source and target
-- **Typed**: Use meaningful relation type
-- **Accurate**: Use exact entity titles
-- **Purposeful**: Add value to graph
-
-**Choosing relation types**:
-
-```markdown
-# Implementation relationship
-- implements [[Feature Specification]]
-
-# Dependency relationship
-- requires [[User Authentication]]
-- depends_on [[Database Connection]]
-
-# Hierarchical relationship
-- part_of [[Payment System]]
-- includes [[Payment Validation]]
-
-# Contrast relationship
-- contrasts_with [[Alternative Approach]]
-- alternative_to [[Previous Design]]
-
-# Temporal relationship
-- leads_to [[Next Phase]]
-- follows [[Initial Setup]]
-
-# Causal relationship
-- caused_by [[Performance Issue]]
-- results_in [[Optimization]]
-```
-
-### Note Templates
+`overwrite=False` explicitly protects against replacing an existing note even when
+the user's write default permits overwrites. Content frontmatter can supply note
+metadata. The tool does not add an H1 for you. Search for related notes first; a
+similar-note advisory after creation is a suggestion to inspect, not proof of a
+duplicate.
 
-**Decision Record**:
+For a full replacement, use the exact returned file path and checksum. A title may
+resolve to a different filename than the one a new title-based write would derive.
 
 ```python
-await write_note(
-    title="Decision: Use GraphQL for API",
-    content="""# Decision: Use GraphQL for API

+## Reading and Navigation
 
-**Technical Specification**:
+`bm_read` resolves one file by path, permalink, exact title, external ID, or memory
+URL. Use returned identifiers rather than guessing paths or normalizing titles.
+Missing notes produce errors; wildcard discovery belongs in `bm_find`, `bm_search`,
+or `bm_context`.
 
 ```python

-## Overview
-Specification for user authentication system using JWT tokens.

-## Observations
-- [requirement] Support email/password and OAuth authentication #auth
-- [requirement] JWT tokens expire after 24 hours #security
-- [requirement] Refresh tokens valid for 30 days #security
-- [technique] Use RS256 algorithm for token signing #cryptography
-- [fact] Tokens include user_id, email, and roles claims #implementation
-- [decision] Store refresh tokens in HTTP-only cookies #security

-
-## Technical Details
-
-### Authentication Flow
-1. User submits credentials
-2. Server validates against database
-3. Generate JWT access token
-4. Generate refresh token
-5. Return tokens to client

-### Tags Strategy
-
-**Effective tagging**:
-
-```python
-# Technology tags
-#python #fastapi #graphql #postgresql
-
-# Domain tags
-#auth #security #api #frontend #backend
-
-# Status tags
-#wip #completed #deprecated #planned
-
-# Priority tags
-#urgent #important #nice-to-have
+Long notes use sections, line ranges, or token budgets, not page numbers. Line
+numbers include frontmatter. Follow the returned continuation information when a
+read is truncated. Use `output_format="json"` when code needs response fields;
+ordinary reads default to text. `include_content=False` returns metadata and the
+checksum without the body. Graph traversal belongs in `bm_context`, not assumed
+`relations` fields on a `bm_read` response.
 
-# Category tags
-#bug #feature #refactor #docs #test
-```
-
-**Example with strategic tags**:
+The same tool reads non-Markdown files; images return as images and other binary
+files as documents. Reading content does not open a host UI or guarantee a rendered
+artifact.
 
 ```python
-await write_note(
-    title="OAuth Integration",

----
-
-## Reading and Navigation
-
-**Reading notes and navigating the knowledge graph is fundamental to building context.**
+`bm_list` lists one level. With `/` and no project constraint it lists project mount
+points. `bm_find` searches recursively, up to ten levels. Both paginate; follow
+`has_more` rather than assuming one page is complete.
 
-### Reading by Identifier
+## Search and Discovery
 
-**Read by title**:
+Use `bm_search` for ranked text or meaning search, and `bm_find` for folder-scoped
+frontmatter inventories. Search defaults to hybrid when semantic search is
+available; choose `mode="text"` for keyword matching.
 
 ```python
-# Simple title
-note = await read_note(
-    identifier="Authentication System",
-    project="main"
-)
-
-# Title in specific folder
-note = await read_note(
-    identifier="specs/Authentication System",
-    project="main"
+await bm_search(query="JWT authentication", mode="text", project="main")
+await bm_search(query="user login security", mode="semantic", project="main")
+await bm_search(query="API design", mode="hybrid", project="main")
+await bm_search(query="API Design", mode="title", project="main")
+await bm_search(query="specs/*", mode="permalink", project="main")
+await bm_search(
+    query="authentication",
+    note_types=["spec", "decision"],
+    filters={"status": "draft", "tags": ["security"]},
+    since="30d",
+    project="main",
 )
+await bm_search(query="performance", items=["observation"], categories=["problem"], project="main")
 ```
 
-**Read by permalink**:
+`items` selects `note`, `observation`, and/or `relation`; `note_types` selects
+frontmatter types. `categories` selects observation categories. Put tags and status
+inside `filters`. See [Metadata Search](metadata-search.md) for operators.
 
 ```python
-# Permalink is auto-generated from title
-note = await read_note(
-    identifier="authentication-system",
-    project="main"
-)
-
-# Permalink with folder
-note = await read_note(
-    identifier="specs/authentication-system",
-    project="main"
+await bm_find(
+    path="specs",
+    filters={"status": "draft", "priority": {"$in": ["high", "critical"]}},
+    fields=["title", "priority"],
+    project="main",
 )
+await bm_search(query="retry", mode="text", lines=2, max_matches=5, project="main")
+await bm_search(query="authentication", projects=["main", "research"], output_format="json")
 ```
 
-### Reading by memory:// URL
-
-**URL formats**:
+`bm_find` cannot combine frontmatter filters with `name` or a non-default depth;
+use `path` to scope the inventory. `bm_search` accepts one scope among `identifier`,
+`path`, a memory URL query, `projects`, or `all_projects`. Line windows report
+literal matches within indexed candidates, not an exhaustive filesystem scan.
 
-```python
-# By title
-note = await read_note(
-    identifier="memory://Authentication System",
-    project="main"
-)
-
-# By folder and title
-note = await read_note(
-    identifier="memory://specs/Authentication System",
-    project="main"
-)
+Search/list/find pages accept 1–100 results. Inspect `has_more` and advance `page`.
+Read selected results with `bm_read`; snippets and compact results are not complete
+notes. Inspect the installed JSON response instead of assuming an undocumented shape.
 
-# By permalink
-note = await read_note(
-    identifier="memory://authentication-system",
-    project="main"
-)
-
-# Wildcards for folder contents
-notes = await read_note(
-    identifier="memory://specs/*",
-    project="main"
-)
+## Building Context
 
-# Cross-project URL (auto-routes to the correct project)
-note = await read_note(identifier="memory://research/specs/api-design")
-```
+Follow relations from a known note or pattern:
 
 ```python
-# Underscores automatically converted to hyphens
-note = await read_note(
-    identifier="memory://my_note_title",
-    project="main"
+await bm_context(
+    identifier="specs/authentication.md",
+    depth=2,
+    since="30d",
+    max_related=20,
+    compact=True,
+    project="main",
 )
-# Finds entity with permalink "my-note-title"
-
-# Both forms work
-note1 = await read_note("memory://api_design", project="main")
-note2 = await read_note("memory://api-design", project="main")
-# Both find same entity
-```
-
-### Response Structure
-
-**read_note response includes**:
-
-```python
-{
-    "title": "Authentication System",
-    "permalink": "authentication-system",
-    "content": "# Authentication System\n\n...",
-    "folder": "specs",

-    "type": "spec",

-            "target_permalink": "authentication-service"
-        }
-    ]
-}
 ```
 
-### Pagination
+`depth` is 1–5. `since` defaults to `7d`, so omission does not mean all history.
+Choose an explicit older date when historical context matters. Context defaults to
+JSON, accepts up to 50 primary results per page, and uses `max_related` to cap related
+results. Compact mode omits bodies and observations while preserving graph shape;
+read the selected notes before quoting their contents.
 
-**For long notes, use pagination**:
+For continuity, search for the thread, read its latest checkpoint, follow relevant
+relations, and verify unresolved claims against current evidence.
 
-```python
-# First page (default: 10 items)
-page1 = await read_note(
-    identifier="Long Document",
-    page=1,
-    page_size=10,
-    project="main"
-)
+## Recording Conversations
 
-# Second page
-page2 = await read_note(
-    identifier="Long Document",
-    page=2,
-    page_size=10,
-    project="main"
-)
+Capture a coherent account of what matters: the problem, decisions and rationale,
+actual results, unresolved questions, and next action. Link to earlier discussions
+instead of copying them. Distinguish verified facts from proposals or estimates.
 
-# Large page size for complete content
-full = await read_note(
-    identifier="Long Document",
-    page=1,
-    page_size=1000,
-    project="main"
-)
-```
+Useful note types include decisions, meetings, research, tasks, and session handoffs.
+Use a readable title, an H1, relevant frontmatter, and sections suited to the work.
+Confirm the write using its returned identifier; never invent a web-app link.
 
-### Reading Raw Content
+## Editing Notes
 
-**For non-markdown files or raw access**:
+`bm_edit` changes existing notes. Missing notes are errors; create them deliberately
+with `bm_write`. Supported commands include append, prepend, find_replace,
+replace_section, insert_before_section, insert_after_section, and set_metadata.
 
 ```python
-# Read text file
-content = await read_content(
-    path="config/settings.json",
-    project="main"
+await bm_edit(
+    identifier="specs/authentication.md",
+    command="append",
+    content="\n- [requirement] Document refresh-token rotation",
+    project="main",
 )
-
-# Read image (returned as base64)
-image = await read_content(
-    path="diagrams/architecture.png",
-    project="main"
+await bm_edit(
+    identifier="specs/authentication.md",
+    command="find_replace",
+    find_text="draft policy",
+    content="approved policy",
+    expected_replacements=1,
+    project="main",
 )
-
-# Read any file type
-data = await read_content(
-    path="data/export.csv",
-    project="main"
+await bm_edit(
+    identifier="specs/authentication.md",
+    command="replace_section",
+    section="Decisions",
+    content="## Decisions\n\nUse rotating refresh tokens.",
+    project="main",
 )
-```
-
-**Difference from read_note**:
-- `read_note`: Parses markdown, extracts knowledge graph
-- `read_content`: Returns raw file content
-- Use `read_note` for knowledge graph navigation
-- Use `read_content` for non-markdown files
-
-### Viewing as Artifact
-
-**For better readability, use view_note**:
-
-```python
-# Display as formatted artifact
-artifact = await view_note(
-    identifier="Authentication System",
-    project="main"
+await bm_edit(
+    identifier="specs/authentication.md",
+    command="set_metadata",
+    metadata={"status": "approved"},
+    project="main",
 )
-
-# Returns formatted markdown suitable for display
-# - Syntax highlighting
-# - Rendered markdown
-# - Better visual presentation
 ```
 
-**When to use view_note**:
-- Showing content to user
-- Presenting documentation
-- Displaying specifications
-- Better than raw markdown for reading
-
-### Directory Browsing
+Read before editing and pass `expected_checksum` when the change depends on the
+revision you read. For repeated headings use a section path (`Auth/Decisions`) or an
+occurrence (`Decisions[1]`). `expected_replacements` must match the actual count;
+there is no `replace_all` parameter. Metadata updates preserve other fields and
+cannot remove keys with null or change title/permalink identity.
 
-**List directory contents**:
+## Moving and Organizing
 
 ```python
-# List top-level folders
-root = await list_directory(
-    dir_name="/",
-    project="main"
-)
-
-# List specific folder
-specs = await list_directory(
-    dir_name="specs",
-    project="main"
-)
-
-# Recursive listing
-all_files = await list_directory(
-    dir_name="/",
-    depth=3,
-    project="main"
-)
-
-# Filter by pattern
-markdown_files = await list_directory(
-    dir_name="docs",
-    file_name_glob="*.md",
-    project="main"
+await bm_move(
+    identifier="specs/authentication.md",
+    destination="archive/authentication.md",
+    project="main",
 )
 ```
 
-**Response structure**:
-
-```python

-    "path": "specs",
-    "files": [
-        {

-## Search and Discovery
+A move changes the file location; do not assume it rewrites the title or permalink.
+Reuse the result's identifiers for later operations. Read the manual for directory
+moves and permalink behavior. To copy knowledge to another project, read the source
+and deliberately create a new note in the destination project.
 
-**Search is the primary way to discover relevant knowledge.**
+Use `bm_delete` only for notes the user authorized removing. Move useful historical
+material into an archive when retaining provenance is appropriate.
 
-### Basic Search
+## Error Handling
 
-**Simple text search**:
+Failures are MCP tool errors, not successful empty results. With JSON output, inspect
+the error code and remediation. Common cases include:
 
-```python
-# Search across all content
-results = await search_notes(
-    query="authentication",
-    project="main"
-)
+- `NOT_FOUND`: search or list to locate the right identifier; do not pretend the read succeeded.
+- `ALREADY_EXISTS`: read the existing note and choose an edit or an explicit overwrite.
+- Revision conflict: re-read and reconcile before retrying with a new checksum.
+- `INVALID_ARGUMENTS`: consult `bm_man` and correct the call; do not silently drop filters.
+- Ambiguous route: pass a project UUID or workspace-qualified name.
 
-# Search with pagination
-results = await search_notes(
-    query="authentication",
-    page=1,
-    page_size=10,
-    project="main"
-)
+An empty search is different from a failed search. Check `has_more` before calling a
+result set complete. Do not retry destructive operations blindly after transport errors.
 
-# Get more results
-results = await search_notes(
-    query="authentication",
-    page=1,
-    page_size=50,
-    project="main"
-)
-```
+## Advanced Patterns
 
-### Advanced Search
+For a bulk update, first enumerate and review the target set, then read each note and
+apply checksum-guarded changes. Preserve provenance when consolidating notes and link
+related material before deleting a source. Avoid reconstructing Markdown from assumed
+search-result observation/relation fields.
 
-**Filter by entity type**:
+Use schemas to validate conventions and identify drift:
 
 ```python
-# Search only specifications
-specs = await search_notes(
-    query="authentication",
-    types=["spec"],
-    project="main"
-)
-
-# Search decisions and meetings
-decisions = await search_notes(
-    query="api design",
-    types=["decision", "meeting"],
-    project="main"
-)
+await bm_schema(command="validate", identifier="specs/authentication.md", project="main")
+await bm_schema(command="infer", note_type="decision", project="main")
+await bm_schema(command="diff", note_type="decision", project="main")
 ```
 
-**Filter by observation category**:
+Schema inference proposes structure; it does not authorize rewriting existing notes.
+For knowledge visualization, gather context and create an ordinary JSON Canvas file
+using filesystem access when available. Do not treat note-writing tools as arbitrary
+binary-file writers.
 
-```python
-# Find all decisions
-decisions = await search_notes(
-    query="",
-    entity_types=["decision"],
-    project="main"
-)
+## Tool Reference
 
-# Find problems and solutions
-issues = await search_notes(
-    query="performance",
-    entity_types=["problem", "solution"],
-    project="main"
-)
+```python
+await bm_man()
+await bm_man(page="bm-write(3)")
+await bm_man(query="frontmatter filters")
 ```
 
-**Date filtering**:
-
-```python
-# Find recent changes
-recent = await search_notes(
-    query="api",
-    after_date="2025-01-01",
-    project="main"
-)
-
-# Combine with other filters
-recent_decisions = await search_notes(
-    query="authentication",
-    types=["decision"],
-    after_date="2025-01-01",
-    project="main"
-)
-```
-
-**Structured frontmatter filters**:
-
-```python
-# Filter by tags and status
-results = await search_notes(
-    query="authentication",
-    tags=["security"],
-    status="in-progress",
-    project="main"
-)
-
-# Complex metadata filters (supports $in, $gt, $gte, $lt, $lte, $between)
-results = await search_notes(
-    query="api design",
-    metadata_filters={
-        "type": "spec",
-        "priority": {"$in": ["high", "critical"]},
-        "tags": ["architecture"]
-    },
-    project="main"
-)
-
-# Metadata-only search (no query needed)
-results = await search_notes(
-    metadata_filters={"type": "spec", "status": "in-progress"},
-    project="main"
-)
-```
-
-### Search Types
-
-Available types: `"text"`, `"title"`, `"permalink"`, `"vector"`/`"semantic"`, `"hybrid"`.
-Default is `"hybrid"` when semantic search is enabled, `"text"` otherwise.
-
-**Text search**:
-
-```python
-# Full-text search across all content
-results = await search_notes(
-    query="JWT authentication",
-    search_type="text",
-    project="main"
-)
-```
-
-**Title and permalink search**:
-
-```python
-# Search by title only
-results = await search_notes(query="API Design", search_type="title", project="main")
-
-# Search by permalink
-results = await search_notes(query="specs/api-design", search_type="permalink", project="main")
-```
-
-**Semantic/vector search**:
-
-```python
-# Semantic/vector search (if enabled)
-results = await search_notes(
-    query="user login security",
-    search_type="semantic",  # or "vector"
-    project="main"
-)
-
-# Override similarity threshold
-results = await search_notes(
-    query="user login security",
-    search_type="semantic",
-    min_similarity=0.5,
-    project="main"
-)
-```
-
-**Hybrid search** (combines text + semantic):
-
-```python
-results = await search_notes(
-    query="authentication best practices",
-    search_type="hybrid",
-    project="main"
-)
-```
-
-**Tag shorthand in query**:
-
-```python
-# Use tag: prefix as shorthand
-results = await search_notes(query="tag:security", project="main")
-```
-
-### Search Response
-
-**Result structure**:
-
-```python
-{
-    "results": [
-        {
-            "title": "Authentication System",
-            "permalink": "authentication-system",
-            "folder": "specs",
-            "snippet": "...JWT authentication for user login...",
-            "score": 0.95,
-            "tags": ["auth", "security"],
-            "type": "spec",
-            "updated": "2025-01-15T09:15:00Z"
-        }
-    ],
-    "total": 15,
-    "page": 1,
-    "page_size": 10,
-    "has_more": true
-}
-```
-
-### Search Strategies
-
-**Broad to narrow**:
-
-```python
-# Start broad
-all_auth = await search_notes(
-    query="authentication",
-    project="main"
-)
-
-# Narrow down
-jwt_auth = await search_notes(
-    query="JWT authentication",
-    types=["spec", "decision"],
-    project="main"
-)
-
-# Very specific
-recent_jwt = await search_notes(
-    query="JWT token implementation",
-    types=["spec"],
-    after_date="2025-01-01",
-    project="main"
-)
-```
-
-**Find related content**:
-
-```python
-# 1. Search for main topic
-auth_notes = await search_notes(
-    query="authentication",
-    project="main"
-)
-
-# 2. Read top result
-main_note = await read_note(
-    identifier=auth_notes["results"][0]["permalink"],
-    project="main"
-)
-
-# 3. Build context from relations
-context = await build_context(
-    url=f"memory://{main_note['permalink']}",
-    depth=2,
-    project="main"
-)
-
-# 4. Search for related terms from relations
-for relation in main_note["relations"]:
-    related = await search_notes(
-        query=relation["target"],
-        project="main"
-    )
-```
-
-**Multi-faceted search**:
-
-```python
-# Search by different aspects
-by_topic = await search_notes(query="API design", project="main")
-by_author = await search_notes(query="Alice", project="main")
-by_date = await search_notes(query="", after_date="2025-01-15", project="main")
-by_tag = await search_notes(query="#security", project="main")
-by_type = await search_notes(query="", types=["decision"], project="main")
-
-# Combine for precision
-precise = await search_notes(
-    query="API security",
-    types=["decision"],
-    after_date="2025-01-01",
-    project="main"
-)
-```

-## Building Context
-
-**Context building enables conversation continuity by traversing the knowledge graph.**
-
-### Basic Context Building
-
-**Simple context**:
-
-```python
-# Build context from entity
-context = await build_context(
-    url="memory://Authentication System",
-    project="main"
-)
-
-# Returns:
-# - The root entity
-# - Directly related entities
-# - Recent observations
-# - Connection paths
-```
-
-### Depth Control
-
-**Shallow context (depth=1)**:
-
-```python
-# Only immediate connections
-shallow = await build_context(
-    url="memory://Authentication System",
-    depth=1,
-    project="main"
-)
-
-# Returns:
-# - Root entity
-# - Entities with direct relations
-# - First-degree connections only
-```
-
-**Deep context (depth=2)**:
-
-```python
-# Two levels of connections
-deep = await build_context(
-    url="memory://Authentication System",
-    depth=2,
-    project="main"
-)
-
-# Returns:
-# - Root entity
-# - Direct relations (depth 1)
-# - Relations of relations (depth 2)
-# - More comprehensive context
-```
-
-**Very deep context (depth=3+)**:
-
-```python
-# Three or more levels
-very_deep = await build_context(
-    url="memory://Authentication System",
-    depth=3,
-    project="main"
-)
-
-# Warning: Can return a lot of data
-# Use for comprehensive understanding
-# May be slow for large graphs
-```
-
-### Timeframe Filtering
-
-**Recent context**:
-
-```python
-# Last 7 days
-recent = await build_context(
-    url="memory://Authentication System",
-    timeframe="7d",
-    project="main"
-)
-
-# Natural language timeframes
-last_week = await build_context(
-    url="memory://API Design",
-    timeframe="1 week",
-    project="main"
-)
-
-last_month = await build_context(
-    url="memory://Project Planning",
-    timeframe="30 days",
-    project="main"
-)
-
-# Minimum: 1 day (enforced since v0.15.0)
-```
-
-**All-time context**:
-
-```python
-# No timeframe = all history
-complete = await build_context(
-    url="memory://Authentication System",
-    depth=2,
-    project="main"
-)
-```
-
-### Context Response Structure
-
-**Response includes**:
-
-```python
-{
-    "root_entity": {
-        "title": "Authentication System",
-        "permalink": "authentication-system",
-        "content": "...",
-        "observations": [...],
-        "relations": [...]
-    },
-    "related_entities": [
-        {
-            "title": "User Database",
-            "permalink": "user-database",

-            "distance": 1,
-            "content": "...",
-            "observations": [...],
-            "relations": [...]
-        },
-        {
-            "title": "Login API",
-            "permalink": "login-api",
-            "relation_type": "implemented_by",
-            "distance": 1,
-            "content": "...",
-            "observations": [...],
-            "relations": [...]
-        }
-    ],
-    "paths": [
-        {
-            "from": "authentication-system",
-            "to": "login-api",
-            "path": [
-                {"entity": "authentication-system", "relation": "implemented_by"},
-                {"entity": "login-api"}
-            ]
-        }
-    ],
-    "summary": {
-        "total_entities": 5,
-        "total_relations": 8,
-        "max_depth": 2,
-        "timeframe": "7d"
-    }
-}
-```
-
-### Context Building Patterns
-
-**Continuing conversations**:
-
-```python
-# User: "Let's discuss authentication"
-
-# 1. Search for topic
-results = await search_notes(
-    query="authentication",
-    project="main"
-)
-
-# 2. Build context from most relevant
-context = await build_context(
-    url=f"memory://{results['results'][0]['permalink']}",
-    depth=2,
-    timeframe="30d",
-    project="main"
-)
-
-# 3. Use context to inform response
-# "Based on our previous work on authentication, including
-#  the JWT implementation and OAuth integration..."
-```
-
-**Exploring knowledge areas**:
-
-```python
-# Start with broad topic
-initial = await build_context(
-    url="memory://API Design",
-    depth=1,
-    project="main"
-)
-
-# Explore interesting branches
-for entity in initial["related_entities"]:
-    if "GraphQL" in entity["title"]:
-        graphql_context = await build_context(
-            url=f"memory://{entity['permalink']}",
-            depth=2,
-            project="main"
-        )
-```
-
-**Finding connection paths**:
-
-```python
-# Build context from both endpoints
-start_context = await build_context(
-    url="memory://Frontend App",
-    depth=2,
-    project="main"
-)
-
-end_context = await build_context(
-    url="memory://Database Schema",
-    depth=2,
-    project="main"
-)
-
-# Analyze paths in response
-# Shows how frontend connects to database through API layer
-```
-

-
-## Recording Conversations
-
-**Capturing conversations in Basic Memory enables long-term context and knowledge accumulation.**
-
-### Permission and Transparency
-
-**Always ask before recording**:
-
-```
-AI: "Would you like me to save our discussion about API authentication
-     to Basic Memory? This will help us continue this conversation later
-     and build on what we've learned."
-
-User: "Yes, please"
-
-AI: [Saves to Basic Memory]
-    "I've saved our discussion to Basic Memory as 'API Authentication Discussion'."
-```
-
-**Be transparent**:
-- Ask permission before saving
-- Confirm after saving
-- Explain what was saved
-- Mention how it helps future conversations
-
-**Your role**: As an AI collaborator, you're helping build knowledge that will outlast any particular AI model or session. Write observations and relations that will be valuable to the human (and future AI assistants) years from now. Think: enduring insights, not ephemeral chat logs. These plain-text markdown files are artifacts worth keeping - make them count.
-
-### What to Record

-## Moving and Organizing
-
-**Organize notes by moving them between folders while maintaining knowledge graph integrity.**
-
-### Basic Move
-
-**Move to new folder**:
-
-```python
-await move_note(
-    identifier="API Documentation",
-    destination_path="docs/api/api-documentation.md",
-    project="main"
-)
-```
-
-**Move with auto-extension**:
-
-```python
-# Both work (v0.15.0+)
-await move_note(
-    identifier="Note",
-    destination_path="new-folder/note.md",
-    project="main"
-)
-
-await move_note(
-    identifier="Note",
-    destination_path="new-folder/note",  # .md added automatically
-    project="main"
-)
-```
-
-### Organizing Knowledge
-
-**Create folder structure**:
-
-```python
-# Move related notes to dedicated folders
-
-# Move specs
-await move_note("Authentication Spec", "specs/auth/authentication.md", project="main")
-await move_note("API Spec", "specs/api/api-spec.md", project="main")
-
-# Move implementations
-await move_note("Auth Service", "services/auth/auth-service.md", project="main")
-await move_note("API Server", "services/api/api-server.md", project="main")
-
-# Move decisions
-await move_note("Decision: OAuth", "decisions/oauth-decision.md", project="main")
-
-# Move meetings
-await move_note("API Review 2025-01-15", "meetings/2025/01/api-review.md", project="main")
-```
-
-**Folder hierarchy**:
-
-```
-project/
-├── specs/
-│   ├── auth/
-│   └── api/
-├── services/
-│   ├── auth/
-│   └── api/
-├── decisions/
-├── meetings/
-│   └── 2025/
-│       └── 01/
-├── conversations/
-└── learnings/
-```
-
-### Batch Organization
-
-**Organize multiple notes**:
-
-```python
-# Get all auth-related notes
-auth_notes = await search_notes(
-    query="authentication",
-    project="main"
-)
-
-# Move to auth folder
-for note in auth_notes["results"]:
-    if note["type"] == "spec":
-        await move_note(
-            identifier=note["permalink"],
-            destination_path=f"specs/auth/{note['permalink']}.md",
-            project="main"
-        )
-    elif note["type"] == "decision":
-        await move_note(
-            identifier=note["permalink"],
-            destination_path=f"decisions/auth/{note['permalink']}.md",
-            project="main"
-        )
-```
-
-### Preserving Relations
-
-**Relations are automatically updated**:
-
-```python
-# Before move:
-# Note A (folder: root) -> relates_to [[Note B]]
-# Note B (folder: root)
-
-# Move Note B
-await move_note(
-    identifier="Note B",
-    destination_path="subfolder/note-b.md",
-    project="main"
-)
-
-# After move:
-# Note A (folder: root) -> relates_to [[Note B]]
-# Note B (folder: subfolder) <- relation still works!
-# Database updated automatically
-```
-
-### Renaming
-
-**Move to rename**:
-
-```python
-# Rename by moving to same folder with new name
-await move_note(
-    identifier="Old Name",
-    destination_path="same-folder/new-name.md",
-    project="main"
-)
-
-# Title and permalink updated
-# Relations preserved
-```
-
-### Archiving
-
-**Move to archive folder**:
-
-```python
-# Archive old notes
-await move_note(
-    identifier="Deprecated Feature",
-    destination_path="archive/deprecated/deprecated-feature.md",
-    project="main"
-)
-
-# Batch archive by date
-old_notes = await search_notes(
-    query="",
-    after_date="2024-01-01",
-    project="main"
-)
-
-for note in old_notes["results"]:
-    if note["updated"] < "2024-06-01":
-        await move_note(
-            identifier=note["permalink"],
-            destination_path=f"archive/2024/{note['permalink']}.md",
-            project="main"
-        )
-```

-## Error Handling
-
-**Robust error handling ensures reliable AI-human interaction.**
-
-### Missing Project Parameter
-
-**Error**: Tool called without project parameter
-
-**Solution**:
-
-```python
-try:
-    results = await search_notes(query="test")
-except:
-    # Show available projects
-    projects = await list_memory_projects()
-
-    # Ask user which to use
-    # "I need to know which project to search. Available projects: ..."
-
-    # Retry with project
-    results = await search_notes(query="test", project="main")
-```
-
-**Prevention**:
-
-```python
-# Always discover projects first
-projects = await list_memory_projects()
-
-# Store active project for session
-active_project = projects[0]["name"]
-
-# Use in all calls
-results = await search_notes(query="test", project=active_project)
-```
-
-### Note Already Exists
-
-**Error**: `write_note` called for a note that already exists
-
-**Solution**:
-
-```python
-# Preferred: use edit_note for incremental updates
-await edit_note(
-    identifier="Existing Topic",
-    operation="append",
-    content="\n- [update] new information",
-    project="main"
-)
-
-# Alternative: replace the entire note
-await write_note(
-    title="Existing Topic",
-    content="# Existing Topic\n...",
-    folder="notes",
-    overwrite=True,
-    project="main"
-)
-```
-
-### Entity Not Found
-
-**Error**: Note doesn't exist
-
-**Solution**:
-
-```python
-try:
-    note = await read_note("Nonexistent Note", project="main")
-except:
-    # Search for similar
-    results = await search_notes(query="Note", project="main")
-
-    # Suggest alternatives
-    # "I couldn't find 'Nonexistent Note'. Did you mean:"
-    # - Similar Note 1
-    # - Similar Note 2
-```
-
-### Forward Reference Resolution
-
-**Not an error**: Forward references resolve automatically
-
-```python
-# Create note with forward reference
-response = await write_note(
-    title="Implementation",
-    content="## Relations\n- implements [[Future Spec]]",
-    folder="code",
-    project="main"
-)
-
-# Response may indicate unresolved reference
-# This is OK - will resolve when target created
-
-# Later, create target
-await write_note(
-    title="Future Spec",
-    content="# Future Spec\n...",
-    folder="specs",
-    project="main"
-)
-
-# Reference automatically resolved
-# No action needed
-```
-
-### Sync Status Issues
-
-**Error**: Data not found, sync in progress
-
-**Solution**:
-
-```python
-# Check sync status
-status = await sync_status(project="main")
-
-if status["sync_in_progress"]:
-    # Inform user
-    # "The knowledge base is still syncing. Please wait..."
-
-    # Wait or proceed with available data
-    # Can still search/read synced content
-else:
-    # Sync complete, proceed normally
-    results = await search_notes(query="topic", project="main")
-```
-
-### Ambiguous References
-
-**Error**: Multiple entities match
-
-**Solution**:
-
-```python
-# Ambiguous title
-try:
-    note = await read_note("API", project="main")
-except:
-    # Search to disambiguate
-    results = await search_notes(query="API", project="main")
-
-    # Show options to user
-    # "Multiple notes found with 'API':"
-    # - API Specification (specs/)
-    # - API Implementation (services/)
-    # - API Documentation (docs/)
-
-    # Use specific identifier
-    note = await read_note("specs/API Specification", project="main")
-```
-
-### Empty Search Results
-
-**Not an error**: No matches found
-
-**Solution**:
-
-```python
-results = await search_notes(query="rare topic", project="main")
-
-if results["total"] == 0:
-    # Broaden search
-    broader = await search_notes(query="topic", project="main")
-
-    # Or suggest creating note
-    # "No notes found about 'rare topic'. Would you like me to create one?"
-```
-
-### Project Not Found
-
-**Error**: Specified project doesn't exist
-
-**Solution**:
-
-```python
-try:
-    results = await search_notes(query="test", project="nonexistent")
-except:
-    # List available projects
-    projects = await list_memory_projects()
-
-    # Show to user
-    # "Project 'nonexistent' not found. Available projects:"
-    # - main
-    # - work
-
-    # Offer to create
-    # "Would you like to create a new project called 'nonexistent'?"
-```
-
-### Edit Conflicts
-
-**Error**: find_replace didn't match expected count
-
-**Solution**:
-
-```python
-try:
-    await edit_note(
-        identifier="Config",
-        operation="find_replace",
-        find_text="old_value",
-        content="new_value",
-        expected_replacements=1,
-        project="main"
-    )
-except:
-    # Read note to check
-    note = await read_note("Config", project="main")
-
-    # Verify text exists
-    if "old_value" in note["content"]:
-        count = note["content"].count("old_value")
-        # Inform user: "Found {count} occurrences, expected 1"
-
-        # Adjust or use replace_all
-        await edit_note(
-            identifier="Config",
-            operation="find_replace",
-            find_text="old_value",
-            content="new_value",
-            replace_all=True,
-            project="main"
-        )
-```
-
-### Permission Errors
-
-**Error**: Can't write to destination
-
-**Solution**:
-
-```python
-try:
-    await move_note(
-        identifier="Note",
-        destination_path="/restricted/note.md",
-        project="main"
-    )
-except:
-    # Inform user about permission issue
-    # "Cannot move note to /restricted/ - permission denied"
-
-    # Suggest alternative
-    # "Try moving to a folder within the project directory"
-
-    # Use valid path
-    await move_note(

-## Advanced Patterns
-
-**Sophisticated techniques for knowledge management and AI collaboration.**
-
-### Knowledge Graph Visualization
-
-**Create visual representations with Obsidian canvas files**:
-
-Gather entities with `build_context`, then write a
-[JSON Canvas](https://jsoncanvas.org/) file (`.canvas`) into the project
-directory. Basic Memory indexes `.canvas` files as JSON, and Obsidian opens
-them for interactive exploration:
-
-```json
-{
-  "nodes": [
-    {"id": "auth-system", "type": "file", "file": "specs/authentication-system.md", "x": 0, "y": 0, "width": 400, "height": 300},
-    {"id": "user-db", "type": "file", "file": "services/user-database.md", "x": 500, "y": 0, "width": 400, "height": 300},
-    {"id": "login-api", "type": "file", "file": "api/login-api.md", "x": 250, "y": 400, "width": 400, "height": 300}
-  ],
-  "edges": [
-    {"id": "edge-1", "fromNode": "auth-system", "toNode": "user-db", "label": "requires"},
-    {"id": "edge-2", "fromNode": "auth-system", "toNode": "login-api", "label": "implemented_by"}
-  ]
-}
-```
-
-### Progressive Knowledge Building
-
-**Build knowledge incrementally over time**:
-
-```python
-# Session 1: Create foundation
-await write_note(
-    title="API Design",
-    content="""# API Design
-
-## Observations
-- [requirement] Need REST API for mobile app
-
-## Relations
-- relates_to [[Mobile Development]]
-""",
-    folder="planning",
-    project="main"
-)
-
-# Session 2: Add details
-await edit_note(
-    identifier="API Design",
-    operation="append",
-    content="""
-- [decision] Using FastAPI framework #python
-- [technique] Auto-generate OpenAPI docs
-""",
-    project="main"
-)
-
-# Session 3: Add related entities
-await write_note(
-    title="API Authentication",
-    content="""# API Authentication
-
-## Relations
-- part_of [[API Design]]
-""",
-    folder="specs",
-    project="main"
-)
-
-# Update original with relation
-await edit_note(
-    identifier="API Design",
-    operation="append",
-    content="""
-- includes [[API Authentication]]
-""",
-    project="main"
-)
-
-# Session 4: Add implementation
-await write_note(
-    title="API Implementation",
-    content="""# API Implementation
-
-## Relations
-- implements [[API Design]]
-""",
-    folder="code",
-    project="main"
-)
-```
-
-### Cross-Project Knowledge Transfer
-
-**Transfer knowledge between projects**:
-
-```python
-# Read from source project
-template = await read_note(
-    identifier="API Architecture Template",
-    project="templates"
-)
-
-# Adapt for target project
-adapted_content = template["content"].replace(
-    "{{PROJECT_NAME}}",
-    "New Project"
-)
-
-# Write to target project
-await write_note(
-    title="API Architecture",
-    content=adapted_content,
-    folder="architecture",
-    project="new-project"
-)
-```
-
-### Knowledge Graph Traversal
-
-**Traverse graph to discover insights**:
-
-```python
-# Start with entry point
-start = await read_note("Product Roadmap", project="main")
-
-# Traverse relations
-visited = set()
-to_visit = [start["permalink"]]
-all_related = []
-
-while to_visit:
-    current = to_visit.pop(0)
-    if current in visited:
-        continue
-
-    visited.add(current)
-    note = await read_note(current, project="main")
-    all_related.append(note)
-
-    # Add related entities to queue
-    for relation in note["relations"]:
-        if relation["target_permalink"] not in visited:
-            to_visit.append(relation["target_permalink"])
-
-# Analyze collected knowledge
-# - All connected entities
-# - Relation patterns
-# - Knowledge clusters
-```
-
-### Temporal Analysis
-
-**Track knowledge evolution over time**:
-
-```python
-# Get recent activity
-week1 = await recent_activity(timeframe="7d", project="main")
-week2 = await recent_activity(timeframe="14d", project="main")
-
-# Compare what's new
-new_this_week = [
-    item for item in week1
-    if item not in week2
-]
-
-# Identify trends
-# - What topics are active
-# - What areas growing
-# - What needs attention
-```
-
-### Knowledge Validation
-
-**Ensure knowledge graph integrity**:
-
-```python
-# Find all forward references
-all_notes = await search_notes(query="", page_size=1000, project="main")
-
-unresolved = []
-for note in all_notes["results"]:
-    full_note = await read_note(note["permalink"], project="main")
-
-    for relation in full_note["relations"]:
-        if not relation.get("target_exists"):
-            unresolved.append({
-                "source": note["title"],
-                "target": relation["target"]
-            })
-
-# Report unresolved references
-# "Found {len(unresolved)} unresolved references:"
-# - Note A -> Missing Target 1
-# - Note B -> Missing Target 2
-```
-
-### Automated Documentation
-
-**Generate documentation from knowledge graph**:
-
-```python
-# Gather all specs
-specs = await search_notes(
-    query="",
-    types=["spec"],
-    project="main"
-)
-
-# Build comprehensive documentation
-doc_content = "# System Documentation\n\n"
-
-for spec in specs["results"]:
-    full_spec = await read_note(spec["permalink"], project="main")
-
-    doc_content += f"\n## {full_spec['title']}\n"
-    doc_content += f"{full_spec['content']}\n"
-
-    # Add related implementations
-    context = await build_context(
-        url=f"memory://{spec['permalink']}",
-        depth=1,
-        project="main"
-    )
-
-    implementations = [
-        e for e in context["related_entities"]
-        if e.get("relation_type") == "implemented_by"
-    ]
-
-    if implementations:
-        doc_content += "\n### Implementations\n"
-        for impl in implementations:
-            doc_content += f"- {impl['title']}\n"
-
-# Save generated documentation
-await write_note(
-    title="Generated System Documentation",
-    content=doc_content,
-    folder="docs",
-    project="main"
-)
-```
-
-### Knowledge Consolidation
-
-**Merge related notes**:
-
-```python
-# Find related notes
-related = await search_notes(
-    query="authentication",
-    project="main"
-)
-
-# Read all related
-notes_to_merge = []
-for note in related["results"]:
-    full = await read_note(note["permalink"], project="main")
-    notes_to_merge.append(full)
-
-# Consolidate
-merged_content = "# Consolidated: Authentication\n\n"
-
-merged_observations = []
-merged_relations = []
-
-for note in notes_to_merge:
-    merged_observations.extend(note.get("observations", []))
-    merged_relations.extend(note.get("relations", []))
-
-# Deduplicate
-unique_observations = list({
-    obs["content"]: obs for obs in merged_observations
-}.values())
-
-unique_relations = list({
-    rel["target"]: rel for rel in merged_relations
-}.values())
-
-# Build consolidated note
-merged_content += "## Observations\n"
-for obs in unique_observations:
-    merged_content += f"- [{obs['category']}] {obs['content']}"
-    if obs.get('tags'):
-        merged_content += " " + " ".join(f"#{tag}" for tag in obs['tags'])
-    merged_content += "\n"
-
-merged_content += "\n## Relations\n"
-for rel in unique_relations:
-    merged_content += f"- {rel['type']} [[{rel['target']}]]\n"
-
-# Save consolidated note
-await write_note(
-    title="Consolidated: Authentication",
-    content=merged_content,
-    folder="consolidated",
-    project="main"
-)

 ## Best Practices
 
-**Guidelines for effective knowledge management and AI collaboration.**
-
-### 1. Project Setup
-
-**Single-project users**:
-- Enable `default_project_mode=true` in config
-- Simplifies tool calls
-- Less explicit project parameters
-
-**Multi-project users**:
-- Keep `default_project_mode=false`
-- Always specify project explicitly
-- Prevents cross-project errors
-
-**Always start with discovery**:
-```python
-# First action in conversation
-projects = await list_memory_projects()
-
-# Ask user which to use
-# Store for session
-# Use consistently
-```
-
-### 2. Knowledge Structure
-
-**Every note should have**:
-- Clear, descriptive title
-- 3-5 observations minimum
-- 2-3 relations minimum
-- Appropriate categories and tags
-- Proper frontmatter
-
-**Good structure example**:
-```markdown
----
-title: Clear Descriptive Title
-tags: [relevant, tags, here]
-type: note
----
-
-# Title
-
-## Context
-Brief background
-
-## Observations
-- [category] Specific fact #tag1 #tag2
-- [category] Another fact #tag3
-- [category] Third fact #tag4
-
-## Relations
-- relation_type [[Related Entity 1]]
-- relation_type [[Related Entity 2]]
-```
-
-### 3. Search Before Creating
-
-**Always search first**:
-```python
-# Before writing new note
-existing = await search_notes(
-    query="topic name",
-    project="main"
-)
-
-if existing["total"] > 0:
-    # Update existing instead of creating duplicate
-    await edit_note(
-        identifier=existing["results"][0]["permalink"],
-        operation="append",
-        content=new_information,
-        project="main"
-    )
-else:
-    # Create new
-    await write_note(...)
-```
-
-### 4. Use Exact Entity Titles in Relations
-
-**Wrong**:
-```markdown
-## Relations
-- relates_to [[auth system]]  # Won't match "Authentication System"
-- implements [[api spec]]      # Won't match "API Specification"
-```
-
-**Right**:
-```python
-# Search for exact title
-results = await search_notes(query="Authentication System", project="main")
-exact_title = results["results"][0]["title"]
-
-# Use in relation
-content = f"## Relations\n- relates_to [[{exact_title}]]"
-```
-
-### 5. Meaningful Categories
-
-**Use semantic categories**:
-- `[decision]` for choices made
-- `[fact]` for objective information
-- `[technique]` for methods
-- `[requirement]` for needs
-- `[insight]` for realizations
-- `[problem]` for issues
-- `[solution]` for resolutions
-- `[action]` for tasks
-
-**Not generic categories**:
-- Avoid `[note]`, `[info]`, `[misc]`
-- Be specific and intentional
-
-### 6. Descriptive Relation Types
-
-**Use meaningful relation types**:
-- `implements` for implementation
-- `requires` for dependencies
-- `part_of` for hierarchy
-- `extends` for enhancement
-- `contrasts_with` for alternatives
-
-**Not generic**:
-- Avoid overusing `relates_to`
-- Be specific about relationship
-
-### 7. Progressive Elaboration
-
-**Build knowledge over time**:
-```python
-# Session 1: Create foundation
-await write_note(
-    title="Topic",
-    content="Basic structure with initial observations",
-    folder="notes",
-    project="main"
-)
-
-# Session 2: Add details
-await edit_note(
-    identifier="Topic",
-    operation="append",
-    content="Additional observations and insights",
-    project="main"
-)
-
-# Session 3: Add relations
-await edit_note(
-    identifier="Topic",
-    operation="append",
-    content="Relations to related topics",
-    project="main"
-)
-```
-
-### 8. Consistent Naming
-
-**Folder structure**:
-- specs/ - Specifications
-- decisions/ - Decision records
-- meetings/ - Meeting notes
-- conversations/ - AI conversations
-- implementations/ - Code/implementations
-- docs/ - Documentation
-
-**File naming**:
-- Use descriptive titles
-- Consistent format
-- Avoid special characters
-
-### 9. Regular Validation
-
-**Check knowledge graph health**:
-```python
-# Find unresolved references
-# Check for orphaned notes
-# Verify relation consistency
-# Update outdated information
-```
-
-### 10. Permission and Transparency
-
-**With users**:
-- Always ask before recording
-- Confirm after saving
-- Explain what was saved
-- Describe how it helps
-
-**Recording pattern**:
-```
-AI: "Would you like me to save our discussion about {topic}?"
-User: "Yes"
-AI: [Saves to Basic Memory]
-    "Saved as '{title}' in {folder}/"
-```
-
-### 11. Context Building Strategy
-
-**For new conversations**:
-```python
-# 1. Search for topic
-results = await search_notes(query="topic", project="main")
-
-# 2. Build context from top result
-context = await build_context(
-    url=f"memory://{results['results'][0]['permalink']}",
-    depth=2,
-    timeframe="30d",
-    project="main"
-)
-
-# 3. Use context to inform response
-# Reference previous knowledge
-# Build on existing understanding
-```
-
-### 12. Error Recovery
-
-**Graceful degradation**:
-```python
-try:
-    # Attempt operation
-    result = await tool_call(...)
-except:
-    # Fall back to alternative
-    # Inform user of issue
-    # Suggest workaround
-```
-
-### 13. Incremental Updates
-
-**Prefer editing over rewriting**:
-```python
-# Good: Incremental update
-await edit_note(
-    identifier="Note",
-    operation="append",
-    content="New information",
-    project="main"
-)
-
-# When full rewrite is needed, use overwrite=True
-await write_note(title="Note", content="...", folder="notes", overwrite=True)
-```
-
-### 14. Tagging Strategy
-
-**Use tags strategically**:
-- Technology: #python #fastapi
-- Domain: #auth #security
-- Status: #wip #completed
-- Priority: #urgent #important
-- Category: #bug #feature
-
-**Not too many**:
-- 3-5 tags per observation
-- Focus on most relevant
-- Avoid tag proliferation
-
-### 15. Documentation as Code
-
-**Treat knowledge like code**:
-- Version control friendly (markdown)
-- Review and refine regularly
-- Keep it DRY (Don't Repeat Yourself)
-- Link instead of duplicating
-- Maintain consistency

+- Keep project routes explicit and reuse returned identifiers.
+- Search before creating; read before editing or making factual claims.
+- Use bounded reads and pagination to control context size without hiding omissions.
+- Preserve Markdown, metadata, and provenance during updates.
+- Write specific observations and meaningful links rather than filling quotas.
+- Respect existing user authorization and confirm meaningful writes.
+- Verify the installed schema when a tool call fails or a host exposes different wrappers.

 Basic Memory automatically indexes custom frontmatter fields so you can query them with structured filters. Any YAML key in a note's frontmatter beyond the standard set (`title`, `type`, `tags`, `permalink`, `schema`) is stored as `entity_metadata` and becomes searchable.

 ## Filter Syntax
 
@@ -99,62 +100,72 @@ This queries the `version` key inside a `schema` object in frontmatter.
 
 **Key rules:**
 - Filter keys must match `[A-Za-z0-9_-]+` (dots separate nesting levels).
-- Each operator dict must contain exactly one operator.
+- Several operators on one field combine with AND logic.
 - `$in` and array-contains require non-empty lists.
 - `$between` requires exactly two values `[min, max]`.
 - `null` is an is-null match and only valid as a plain equality value.
 - Comparison and `$between` bounds must be finite numbers. A magnitude no float can hold — a 400-digit integer, which JSON keeps as an ordinary `int` — is refused as a filter error rather than compared against an infinite bound.

+`bm_search` is the single search tool for text queries, metadata filters, or both. The `query` parameter is optional.
 
 **Relevant parameters:**
 
 | Parameter | Type | Description |
 |-----------|------|-------------|
 | `query` | string (optional) | Text search query. Omit for filter-only searches. |
-| `metadata_filters` | dict | Structured filter dict (see syntax above) |
-| `tags` | list[str] | Convenience shorthand — merged into `metadata_filters["tags"]` |
-| `status` | string | Convenience shorthand — merged into `metadata_filters["status"]` |
+| `filters` | dict | Structured filter dict (see syntax above) |
+| `project` | string | Project name, workspace-qualified name, or external UUID |
 
-**Merging rules:** `tags` and `status` are convenience shortcuts. They are merged into `metadata_filters` using `setdefault` — if the same key already exists in `metadata_filters`, the explicit filter wins.
+Put `tags` and `status` inside `filters`; they are not separate MCP parameters.
 
 **Examples:**
 
 ```python
 # Text search filtered by metadata
-await search_notes("authentication", metadata_filters={"status": "draft"})
+await bm_search("authentication", filters={"status": "draft"})
 
 # Filter-only search (no query needed)

    - Synthesize a new version that integrates the latest understanding from the conversation
-   - Overwrite via `write_note` with `overwrite=True` and `expected_checksum` set to that checksum (same title, same `thread_id` if used, same directory). A `NOTE_REVISION_CONFLICT` error means another session changed the note since you read it: read it again and re-synthesize

+## Tool contract
+
+These skills target the Basic Memory 1.0 MCP surface. Use `bm_man(page="bm_search")`
+(or the relevant tool name) to check the installed server's parameters.
+
+- `bm_read` reads one exact note or file, with optional section or line bounds.
+- `bm_write` creates or replaces a note; use its exact `identifier` path when replacing it.
+- `bm_edit` uses `command`, including `set_metadata` for frontmatter-only updates.
+- `bm_move` takes `destination`; `bm_delete` removes a note or directory.
+- `bm_list` lists one folder level. At `/` without `project`, it lists projects.
+  `bm_find` recurses and supports `filters` plus `fields` for metadata discovery.
+- `bm_search` takes `mode`, `filters`, `items`, and `since`; `lines` requests matching lines.
+- `bm_context` takes `identifier`, graph `depth`, and `since`.
+- `bm_project(command="list"|"create"|"recent")` handles project discovery and activity.
+- `bm_schema(command="validate"|"infer"|"diff")` handles schemas.
+- Cloud adds `bm_agent` and Cloud-only read options. Check that the connected server
+  exposes them before using those workflows.
+
+`project` accepts a name, `workspace/project`, or external ID. Pass it explicitly
+when working across projects. Page list/find/search results until `has_more` is
+false (maximum `page_size=100`); context pages currently cap at 50. For revision-guarded
+changes, read as JSON and pass `checksum` as `expected_checksum`.
+The CLI examples retain their `bm cat`, `bm find`, and other CLI command shapes.

    - Synthesize a new version that integrates the latest understanding from the conversation
-   - Overwrite via `write_note` with `overwrite=True` and `expected_checksum` set to that checksum (same title, same `thread_id` if used, same directory). A `NOTE_REVISION_CONFLICT` error means another session changed the note since you read it: read it again and re-synthesize

 that belong elsewhere. Suggest grouping related notes into topic folders, adding

 - The `permalink` is auto-generated from the `title` and `directory`. For example, title "API Design Decisions" in directory "specs" produces permalink `specs/api-design-decisions` and memory URL `memory://specs/api-design-decisions`.

If the entity exists, `bm_edit` it instead. For people and other proper nouns, use **title search** — semantic search is unreliable for names.
 2. **Exact casing, exact paths.** `Tasks/` and `tasks/` are different directories. Take folder paths from the instruction note, character for character. If a write would create a new top-level folder you didn't plan, that's a casing error — stop and fix.
 3. **Explicit project on every call.** In multi-project setups, pass the project explicitly on every read, search, and write. Writes to the wrong project are invisible until much later.
 4. **Read before overwrite.** Full-note overwrites must start from the current content — never reconstruct a note from memory of what it contained. Read as JSON and pass its `checksum` as `expected_checksum`; a revision conflict means someone else edited the note, so re-read before writing.
-5. **Watch write results.** If a write returns a permalink ending in `-1` or `-2`, you just created a duplicate: delete it and re-write the original with overwrite semantics.
