@critique-bot
Talk to Critique on GitHub pull requests — questions, explanations, and on-demand review commands.
Once the GitHub App is installed, you can @mention Critique in PR conversation threads. The bot reads the PR diff, description, thread history, and (for inline comments) the file and line context before replying.
Mention syntax
On the hosted Critique GitHub App, mention @critique-bot. GitHub may display the account as @critique-bot[bot] — do not type [bot] yourself. The legacy alias @critique is also accepted by the parser.
Self-hosted or white-label installations may use a different app slug; your admin will tell you which @name to use.
@critique-bot why did we switch from useEffect to useSyncExternalStore here?Works in PR comments and inline review comments on specific lines.
Commands
| Syntax | What it does |
|---|---|
@critique-bot <question> | Ask anything about the PR or diff |
@critique-bot /review | Run the full review pipeline (uses credits) |
@critique-bot /ask <question> | Same as a plain mention |
@critique-bot /explain | Explain the PR or the code at the commented line |
@critique-bot /fix | Suggest a concrete fix for the discussed issue |
@critique-bot /improve | Suggest quality or architecture improvements |
@critique-bot /security | Security-focused pass on the diff |
@critique-bot /tests | Suggest missing or stronger tests |
@critique-bot /help | Show command help in the thread |
/review is the only command that reruns the full automated pipeline (Scout → specialists → synthesis). Other commands use a single focused model call.
What the bot knows
For each mention, Critique assembles fresh context:
- PR diff (within configured file limits)
- Title, description, and comment thread
- Selected repository context when indexing is available
- For inline comments: path, hunk, and line
Mentions are independent — there is no hidden multi-turn session between separate comments on the same PR.
Configuration
Default mention names work for the hosted Critique app (critique-bot). Operators can override detection with GITHUB_APP_BOT_NAME or GITHUB_APP_SLUG on self-hosted deployments.
Chat model choice for PR comments is managed by Critique operators — you do not need to configure models in GitHub.
Rate and cost
There is no small fixed cap on mentions per PR, but each mention is a real model call. Very long threads increase context size and latency. Prefer /review only when you need a full gate rerun.
