Priority: ➖ Normal Estimated code review effort: 5 (Critical) | ~120 minutes Change: Feature Merge Risk: 🔵 Low · up to The new Shift-Tab effort cycling can, in rare failure cases, raise an unhandled error that may end the CLI unexpectedly. Adding a catch handler is a small fix. The remaining issues are documentation and minor performance nits. The change is mergeable with that follow-up. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The inspected changes primarily affect local interaction and display. The new clipboard capability returns paths without reading or sending their file contents, and the effort shortcut does not change permissions or saved defaults. Risk remains low, but the bundled macOS binaries and some affected behavior have not been fully verified. Retained concerns Security review detailsSecurity Blast Radius

614-616: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low valueCodeQL flags polynomial backtracking in
normalizeScriptValue.The
/\s*([=+-])\s*/gregex runs on script text from model output. On long runs of whitespace with no operator, the engine retries\s*at each start position. The cost is quadratic in the run length. Script arguments are usually short, so the practical impact is low. A lookaround-free form avoids the scan:♻️ Proposed fix
function normalizeScriptValue(value: string): string { - return value.trim().replace(/\s*([=+-])\s*/g, "$1"); + return value.trim().replace(/[ \t\n\r]*([=+-])[ \t\n\r]*/g, "$1"); }The cleanest fix is a small loop that drops whitespace next to
=,+, or-. This loop avoids regex backtracking completely.🤖 Prompt for AI Agents

rejections from the async cycleThinkingEffort call; catch errors and display
them through the existing error-reporting mechanism so the Shift-Tab handler
cannot produce an unhandled rejection.

other examples and the package name declared in package.json.

…ode (#371) ## Requirement or Bug Keep the xhigh effort border distinct from plan mode after #369 made the primary color periwinkle. ## Bug Reproduction Steps On `main`, pick xhigh effort with Shift-Tab, then turn on `/plan`. The prompt border is `#A78BFA` (xhigh) in one case and `#B4B8F8` (plan, periwinkle primary) in the other. The two shades are hard to tell apart. ## Root Cause #369 changed `primary`, and `modePlan` with it, to periwinkle `#B4B8F8`. That moved the plan color close to the existing `effortXHigh` violet. This is a palette fix, not a workaround. ## Code Changes `effortXHigh` changes from `#A78BFA` to `#D58BF0` (dark) and from `#7048B6` to `#8E3AA8` (light). The docs table and the unreleased periwinkle changeset are updated. Contrast: light xhigh on white is 6.32:1, dark xhigh on black is 8.78:1. ## Behavior Changes and Affected Users | Behavior | Before | After | Who relies on the old behavior | Escape hatch | |---|---|---|---|---| | Prompt border at xhigh effort | `#A78BFA` / `#7048B6` | `#D58BF0` / `#8E3AA8` | none (visual only) | custom theme `effortXHigh` | Affected module: `apps/pythinker-code/src/tui/theme/colors.ts`. TUI tests: 2896 passed. ## Checklist - [x] I have read the [CONTRIBUTING](https://github.com/PyModel/pythinker-code/blob/main/CONTRIBUTING.md) document. - [ ] I have linked a related issue (external PRs: issue must have a maintainer's `/approve`). - [ ] I have added tests that prove my feature works. (palette value change; existing contrast tests cover it) - [x] The behavior-change table above is complete, and every removed behavior or flipped default is named in the changeset and either has an escape hatch or was explicitly approved by a maintainer in this PR. - [x] Ran `gen-changesets` skill, or this PR needs no changeset. - [x] Ran `gen-docs` skill, or this PR needs no doc update.

Requirement or Bug
Give the TUI pi's fixed-bottom dock, make Shift-Tab cycle thinking effort, replace per-server MCP lines with one loading line, and sync pi-tui to upstream v1.0.1.
Bug Reproduction Steps
N/A (feature PR). The Shift-Tab part fixes a mismatch: the welcome tip said "shift+tab cycles thinking effort", but Shift-Tab toggled plan mode.
Root Cause
N/A for the dock, effort cycle, and pi-tui sync. For the MCP line: each server that connected printed its own permanent
MCP server "x" connected · N toolsline. While fixing that, the startup status snapshot could also overwrite newer livemcp.statusevents, which could leave a stale "loading" state on screen. Live events now win over the snapshot.Code Changes
Seven commits, each one slice:
tui/config.ts,tui-mode-selector.ts):DEFAULT_TUI_CONFIG.tuiModeisfullscreen, and the "(experimental)" label is gone. On exit, fullscreen still replays the transcript to the main screen.editor-keyboard.ts,pythinker-tui.ts,commands/config.ts): Shift-Tab steps through the model's effort segments (withoutoff) and wraps. Boolean-thinking models toggle on/off. It usesperformModelSwitchwith a newquietoption, so a key press adds no transcript line. The pick lasts for this session only (/effortstill saves it). While a reply streams, the key does nothing. When no prompt highlight is active, the prompt frame uses the theme'seffort*color; plan, bash, and slash highlights still take precedence. The tip, help panel, and docs are updated.custom-editor.ts): the prompt is drawn as two─rules with no sides. When a/btwpanel is attached above (connectedAbove), the old box is kept, so the panel border still closes.activity-pane.ts,activity-spinner.ts,custom-editor.ts): while the agent works, the editor's top rule becomes── ⠋ Working · tip ───. The spinner keeps its lifecycle; only where it draws changes, so the dock height does not change.session-event-handler.ts, newmcp-loading-line.ts): one● Loading MCP: a, bline with the shared blinkingSTATUS_BULLET. It lists only the servers still pending and is removed when none are left. Failed and needs-OAuth servers still print their own line, which stays.packages/pi-tui): a three-way merge from the old sync point53816d7(v0.85.1) toa7229ddc. Fork changes are kept. Upstream's privateasciiVisibleWidthis renamedasciiTabVisibleWidth, because the fork already exports a function with that name. Upstream's new files received only!/bracket fixes for our stricter tsconfig. The darwin.nodeprebuilds were rebuilt from the revieweddarwin-platform.m. Their exports and linked libraries match upstream's v1.0.1 binaries.UPSTREAM.mdrecords the new sync point. No new dependencies.Behavior Changes and Affected Users
