kebab-case slug. Becomes the filename agents/<name>.md and the name: frontmatter key.
This drives auto-invocation — include concrete trigger examples.
Claude Code reads this to decide when to delegate to the agent. Phrases like "Use this agent when…", "for example, after a refactor…" make invocation reliable.
Pick the tools the agent may use. "All tools" omits the tools: key so the agent inherits everything available to the parent.
"Inherit" omits the model: key.
Tints the agent in the Claude Code UI.

You are a senior code reviewer. When invoked:
1. Run `git diff` to see what changed.
2. Focus on correctness, security, readability, and test coverage.
3. Report findings grouped by severity (blocking / should-fix / nitpick).
4. For each finding, point at the exact file and line and suggest a concrete fix.
Be direct. Praise sparingly. Never approve code you have not actually read.
