Use This When

• A task is ready to implement.
• The agent needs to inspect local code before writing.
• Existing patterns, tests, or integration points matter.

Skip When

• The edit is trivial and the relevant context is already visible.
• The task is documentation-only and no repo pattern discovery is needed.

Output

• Files likely to change.
• Existing patterns to follow.
• Edge cases and failure modes.
• Test and validation commands.
• Implementation constraints.

Handoff

/review-ai should receive the implemented diff plus the brief, so review can check whether the code matches the intended task.
