review

target = $ARGUMENTS

If target is not provided, review the PR/MR of the current branch. If target is a local path or branch name (not a PR/MR number), skip platform detection and use git diff directly.

Fetching the Diff

Use the platform's CLI to fetch the PR/MR diff, description, and CI status.

Gathering Context

The diff alone shows what changed, not what could break.

1. Read full files for each changed file — understand the surrounding code, not just the hunks
2. Read the PR description and any linked issues for intent and acceptance criteria
3. For complex changes, trace one level of callers/callees to assess blast radius
4. Check CI status — note pass/fail state
