Final CLI polish from the pre-publish regression

[elemdos]

From the final five-scenario regression on the release build:

• primo add port. It refused whenever anything held port 3000, including unrelated dev servers. That was logged as a blocker in a run where a parallel session held 3000. It now picks a free port when a non-Primo program holds the default. It still refuses for a running Primo (the dev race guard) or an explicit --port. Checked with a python3 -m http.server on 3000: the add succeeds through the next free port, and --port 3000 refuses with a hint.
• primo dev from the wrong folder. Running it from the folder that contains the workspace (right after primo init <name>) said "Run primo new first". It now says cd <workspace>.
• primo new --skip-dev wording. "Isn't registered yet" confused agents in 3 of 5 runs, since the next primo dev picks the site up. It now says exactly that.
• CLAUDE.md gets a header explaining that @AGENTS.md is a Claude Code import (one agent read it as a placeholder).

Tests: 93 pass (1 skip needs a real binary). The CLAUDE.md test now matches the import line instead of the whole file.

Summary by CodeRabbit

• Bug Fixes

  • When the default port is occupied by a non-Primo service, site creation now selects an available port and reports the change. An occupied explicitly requested port still causes the command to exit.
  • When primo dev can’t find site configuration, it provides guidance based on whether it detects a workspace or site directories. If configuration exists but can’t be read, it reports the error and exits.

• Documentation

  • Generated project guidance now includes a workspace introduction before importing shared instructions.

• New Features

  • When starting the CMS is skipped during site creation, the message clarifies that the site will load the next time the CMS starts.

📝 Walkthrough

Walkthrough

The CLI now selects a free port when an occupied default port is held by another program. The dev command updates startup diagnostics for configuration errors and missing workspaces. The new command updates skip-dev messaging and generated CLAUDE.md content.

Changes

Development port selection

Layer / File(s)	Summary
Handle occupied default ports src/commands/add.ts	The command retains requested-port metadata. If the default port is occupied by a non-Primo process, it selects a free port and reports the replacement. An occupied explicitly requested port still causes an exit.

Workspace setup guidance

Layer / File(s)	Summary
Diagnose workspace configuration src/commands/dev.ts	The command reports non-ENOENT configuration read errors. When configuration is missing, it searches non-hidden child directories for server configuration files and displays sanitized workspace guidance.
Update site creation instructions src/commands/new.ts, tests/site-ids.test.mjs	The --skip-dev message now says the site loads when the CMS next starts. Generated CLAUDE.md files include a workspace heading and explanation before the AGENTS.md import. The test checks for the import as a line.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 98815

Workspace discovery improves startup guidance, but a directory name containing raw line breaks can still alter the diagnostic’s terminal output. This is a bounded issue; complete filename escaping remains warranted.

Review details

Systems and components

• observed — src (service) was modified; 3 changed files map to changed impact.
• observed — tests (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in src/commands/add.ts: The dev-port import now includes select_dev_port.
• observed — Modified behavior in src/commands/add.ts: add_site now keeps the requested-port metadata alongside the initial port, enabling later logic to distinguish explicit from default port selection.
• observed — Modified behavior in src/commands/add.ts: An occupied port with a healthy Primo server still causes an exit. An occupied explicitly requested port also causes an exit, but an occupied default port held by another program now triggers selection of a free port and a message reporting the replacement; previously, all occupied ports caused an exit.
• observed — Modified behavior in src/commands/new.ts: The --skip-dev message now says the site loads into the CMS the next time it starts, replacing the prior notice that it was not registered and the instruction to run primo dev.

- Line 941: Update the catch around read_site_config so only ENOENT produces the
missing-configuration message; rethrow other errors, including unreadable-file
and YAML parsing errors. Preserve the existing missing-configuration behavior
for absent configuration files.
- Line 939: Escape terminal control characters in workspace names before
interpolating them into the `spinner.fail` message in the `primo dev` flow. Use
the escaped names for both the suggested `cd` target and the
discovered-workspaces list, while preserving the existing message behavior.
