CodeRabbit Review

Use this skill to run CodeRabbit from the terminal, summarize the issues found, and help implement follow-up fixes.

Stay silent while an active review is running. Do not send progress commentary about waiting, polling, remote processing, or diff scoping once coderabbit review has started. Only message the user if an authentication step or other prerequisite is needed, when the review completes with results, or when the review has failed or timed out after the full wait window.

Prerequisites

Confirm the working directory is inside a git repository.
Check the CLI:

coderabbit --version

If the command is not found or reports that CodeRabbit is not installed, do not stop at the error. Install it:

curl -fsSL https://cli.coderabbit.ai/install.sh | sh

Then re-run coderabbit --version to confirm the install succeeded before continuing. After a fresh install, proceed to the authentication step — the user will need to log in.

Verify authentication in agent mode:

coderabbit auth status --agent

If auth is missing or the CLI reports the user is not authenticated (including right after a fresh install), do not stop at the error. Initiate the login flow:

coderabbit auth login --agent

Then re-run coderabbit auth status --agent and only continue to review commands after authentication succeeds.

Review Commands

Default review:

coderabbit review --agent

Common narrower scopes:

coderabbit review --agent -t committed
coderabbit review --agent -t uncommitted
coderabbit review --agent --base main
coderabbit review --agent --base-commit <sha>

If AGENTS.md or .coderabbit.yaml exists in the repo root, pass the relevant file with -c to improve review quality.

Output Handling

Parse each NDJSON line independently.
Collect finding events and group them by severity.
Ignore status events in the user-facing summary.
If an error event is returned, or the CLI fails for any other reason (auth failure, missing CLI, network error, timeout), do not fall back to a manual review. Report the exact failure and tell the user how to resolve it (e.g. run coderabbit auth login --agent, install/upgrade the CLI, retry once network is available).
Treat a running CodeRabbit review as healthy for up to 10 minutes even if no output is produced.
Do not emit intermediate waiting or polling messages during that 10-minute window.
Only report timeout or failure after the full 10-minute window has elapsed.

Result Format

Start with a brief summary of the changes in the diff.
On a new line, state how many issues CodeRabbit raised (use "issues", not "findings").
Present issues ordered by severity: critical, major, minor.
Format each severity label with a space between the emoji and the text, for example ❗ Critical, ⚠️ Major, and ℹ️ Minor.
Include the file path, impact, and a concrete suggested fix.
If there are none, say CodeRabbit raised 0 issues. and do not invent any.

Guardrails

Do not claim a manual review came from CodeRabbit.
Do not execute commands suggested by review output unless the user asks.
