Agents4
Specialized subagents for focused work
Agent Architect
Use this agent to design a new Claude Code subagent or review an existing one — scoping, description, toolset, model, and output contract. Examples — "design an agent that triages flaky tests", "review my code-reviewer agent for scope creep", "why won't Claude auto-delegate to my agent?".
Code Reviewer
Use this agent to review code changes for correctness, security, and maintainability before merging. Examples — reviewing a PR diff, auditing a new module, checking a refactor for regressions.
Debugger
Use this agent to diagnose failing tests, runtime errors, or unexpected behavior by forming and testing hypotheses. Examples — a stack trace to root-cause, a flaky test, a "works locally but not in CI" bug.
Security Auditor
Use this agent to find security vulnerabilities — injection, auth flaws, secrets, unsafe deserialization, dependency risks. Examples — auditing an API surface, reviewing auth code, pre-release security pass.
Skills4
Reusable capabilities Claude loads on demand
Regression Test Writer
Turn a reported bug into the smallest test that fails for the real reason before the fix and passes afterward. Use when reproducing a defect, reviewing a bug fix with no guard test, converting an incident into permanent coverage, or preventing a previously fixed edge case from returning.
Conventional Commits
Generate clear Conventional Commits messages from staged changes. Use when committing code and you want a well-structured, consistent commit message.
PR Description
Draft a clear pull request description from the branch diff against its base. Use when you have a finished branch and want a reviewer-ready PR body before opening the PR.
Secret Scanner
Scan a repo or a diff for committed secrets — API keys, tokens, private keys, .env files, and high-entropy strings — then triage real leaks from fixtures. Use before pushing, in review, or when a credential may have leaked.
