Use Gemini as a third external reviewer alongside two other vendors: diff review with an APPROVE or REQUEST_CHANGES verdict, and QA-breaker duty in the post-build test ritual. Headless over REST with a CLI fallback, and verdicts go to a shared usage journal. Triggers: "/gemini review", "gemini opinion on this diff".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# gemini — the third vendor in the "second pair of eyes" Its siblings: **Codex** (`secondop.py` / `codex_review.py`, the default) and **Grok** (`grok_review.py`, a CLI on the hub). Gemini is the third independent vendor: it rescues the verdict when Codex has burned through its quota, and as a hetero-pair it breaks what the other two never saw. ## When I call it - In **/tt Step 2.5**, rail 3: Codex unavailable/quota-blocked · a contested COUNTER · a safety-critical artifact (call two or three of them) · the operator says "ask Gemini". - Diff review alongside `cc_review.py` / `codex_review.py` / `grok_review.py`. - A third voice on architecture/plan review when Claude and Codex disagree. ## How (headless, no browser) The breaker for /tt (the verdict is logged into `secondop` automatically, no manual `log-ext` needed): ``` python "%USERPROFILE%\.claude\scripts\cc-review\gemini_review.py" break --task <task-id> --context "<what we built + what has already been checked>" ``` Diff review: ``` python "%USERPROFILE%\.claude\scripts\cc-review\gemini_review.py" review --repo "<path to the repo>" ``` Is the rail alive (before the ritual leans on it): ``` …

How to install
mdr add tonydzi/second-brain-starter-kit/gemini@sha256:0bb6cba2fba3fdbcThe line at the top of this page pins the label git:20261007.cd6c208, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
