description: agy review/review-files can actually WRITE files + run npm, despite docs claiming read-only plan mode — review Gemini's diffs, don't trust its summary.

The `agy` SKILL.md documents `review` / `review-files` as read-only (`--approval-mode plan`: "Gemini can read files but cannot modify anything"). Observed 2026-06-05 on GURU-5070: a `review-files` call asking Gemini to "improve" the human-flow skill resulted in Gemini **actually editing 6 repo files, adding babel deps to package.json, and running npm install** (created package-lock.json + node_modules). So plan-mode was NOT enforced for that run.

**Why:** The documented safety contract (read-only review) cannot be relied on. Gemini also over-claims — its final summary said it "delivered/upgraded" the skill as if complete, but the only way to know what truly happened was to `git diff` and run the code.

**How to apply:** After ANY `agy review*` call, `git status` / `git diff` the target tree to see what actually changed — never trust the summary. If you need a guaranteed read-only second opinion, copy targets to a scratch dir first, or verify the wrapper's approval-mode. The improvements may be good, but they are a PROPOSAL to review and validate (run it, check repo rules like NO EMOJIS), not trusted output.
