Code Review

Analyze code changes for bugs, security issues, and correctness problems. Return structured findings.

Step 1: Determine the Diff Target

Determine what to review based on context:

• Uncommitted changes: --uncommitted
• Against a base branch: --base <branch>
• Specific commit: --commit <sha>

Default to reviewing against the repository's default branch (detect via gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name'). If the caller specifies a different target, use that.

Step 2: Review Changes

1. Run the appropriate diff command to obtain the changes
2. For each changed file, read enough surrounding context to understand the change
3. Apply the bug determination criteria and return findings in the output format below
