Code Review
This pull request updates the agent's prompt in review/agent.ts to include instructions on validating findings, making minimal fixes, verifying edits via tests, and restoring files if verification fails. The review feedback suggests clarifying that the agent is allowed to use git checkout or git restore to discard unverified changes, as the general instruction to avoid git might otherwise prevent it from reliably restoring files.

Since the prompt explicitly instructs the agent not to use git (line 203), the agent might take this too literally and avoid using git checkout or git restore to discard its changes. This could lead to the agent trying to manually rewrite files to their original state, which is highly error-prone. Clarifying that using git is allowed specifically for discarding unverified changes provides a reliable way for the agent to restore the working tree.

Good catch — applied in 09f99e5. Worded as "git restore (the one permitted git use)" so the no-git rule stays intact for everything else, and extended to deleting files the agent created (git restore doesn't cover untracked files).

The pr-reviewer pushed an unverified rewrite to cloud#1927 that reintroduced the bug the PR fixed (details in cloud#1926). Four gaps in the prompt enabled it: - it acted on a stale bot comment that was already fixed at head - it rewrote working code far beyond the finding - it treated "TypeScript compiles" as verification for a change to shell-script *generation*, where only executing the generated script shows behavior (the unit tests assert string composition and pass for behaviorally broken output) - it left unverifiable edits in the working tree, which cloud commits and pushes unconditionally after the harness exits Add prompt rules for each: validate findings against the current checkout, smallest demonstrated fix only, run tests for touched files and exercise generated output, and restore files / go advisory when verification is impossible.

Clarify the required action when tests run but fail.
The verification instructions have a logical gap:
- Line 214 addresses when "you cannot verify an edit" (tests cannot run)
- Lines 210-211 require running tests
- Missing: What should the agent do when tests run but fail?
The current wording only covers two scenarios:
- Tests run and pass → keep edits ✓
- Tests cannot run → restore files (line 214-215) ✓
- Tests run but fail → ? (not specified)
This ambiguity could lead to the agent pushing edits that break tests, or unnecessarily restoring files when test failures are expected (e.g., the fix is incomplete but the approach is correct).
Consider adding explicit guidance such as:
- "If tests fail, restore files and present the fix as advisory," or
- "If tests fail, document the failure and why the edits are still correct," or
- "If your edits cause new test failures, restore files unless you can also fix the failing tests."

…dits The pr-reviewer's 5a50f23 resolved the no-git rule vs git-restore "contradiction" in the wrong direction: it banned git entirely and told the harness to revert edits "with normal file editing tools" — the error-prone manual rewrite that the human-endorsed review feedback on this PR deliberately moved away from. An agent that read a file partially cannot faithfully reconstruct it; "git restore <file>" always restores HEAD, and the no-git rule exists to stop commits and pushes, not local restores. Keep the bot's reviewHarnessPrompt extraction and its regression-test idea, but assert the right invariant: the restore-only carve-out must stay framed as the exception, and no state-mutating git verb may appear.
