Mostly efficient, but the startup banner and the version-locked model name composer-2.5-fast recur across Quick Reference, Step 1, and the normal-example, and Step 0/Step 1 overlap on the same banner concept — tightening opportunities remain.

Step 2 provides a fully executable, complete bash script with the valid_root resolution logic, explicit error messages and exit codes, plus concrete invocation examples and specific config paths — copy-paste ready.

A clearly sequenced Step 0–3 flow with explicit validation checkpoints (empty-question guard, valid_root probes, exit codes 1/2) and error-recovery fallbacks; the read-only, non-destructive nature means the destructive-cap does not apply.

Well-sectioned and the external rule-file reference is clearly signaled, but it is a ~190-line monolith with no bundle files and dense inline sections (narration rules, trust-boundary table) that could be split into one-level-deep references.

Lists multiple concrete actions — "questions, investigation, design discussion, and adversarial sanity checks" — matching the anchor for several specific concrete actions rather than vague domain naming.

Clearly answers both what (read-only cursor-agent delegate, locked to ask mode) and when (explicit "Use when user says..." triggers), plus a "Do NOT load for" exclusion, in third-person voice.

Explicit natural triggers users would say ("ask cursor, cursor sanity check, get a second opinion, adversarial review, design discussion, investigate with cursor, cursor:ask") give good coverage of common phrasings.

A clear read-only-delegation niche with distinct triggers, further disambiguated from cursor:do and breezing --cursor via the explicit exclusion clause, making wrong-skill triggering unlikely.
