Quality

Base defines universal coding constraints, architectural patterns, and TDD rules for writing simple, maintainable code. Use it when setting project standards, organizing specs, or tracking atomic todos.

Code Deduplication prevents semantic code duplication by checking a code index before adding new functions. It is used to reuse or extend existing capabilities and keep the codebase from growing redundant implementations.

Code Graph uses an AST-based code graph to find symbols, trace dependencies, and assess blast radius before reading files. Use it for planning and navigating codebases in Claude Code via MCP.

Code Review enforces automated reviews before commits and deployments, with ADR gate checks for architectural compliance. Use it to run Claude, Codex, Gemini, or multiple engines on the same change.

Codex Review uses OpenAI Codex CLI to review code for bugs, security flaws, and quality issues. Use it in the terminal, PR comments, or CI for automated review of changes.

CPG Analysis uses Joern and CodeQL for deep control-flow, data-flow, and taint analysis. Use it for security audits, vulnerability detection, dead code checks, and cross-function impact analysis.

Pair Programming delivers code and a structured self-review in one pass for cases like pair programming, 'write and review,' or high-reliability implementation. It checks correctness, security, performance, readability, and robustness, then flags remaining tradeoffs.

Security Audit checks code, dependencies, secrets, and server configuration for common security issues. Use it for vulnerability scanning, dependency review, and CI/CD or infrastructure security audits within authorized systems.

Bug Fix Expert helps diagnose Python errors from tracebacks, identify the root cause, and apply the smallest necessary fix. Use it when a test or runtime failure needs targeted debugging and verification.

Golang Expert provides guidance on Go style, concurrency, error handling, testing, and project structure. Use it when writing or reviewing Go code and organizing Go applications.

Refactor Expert helps restructure Python code one change at a time while preserving behavior. Use it to split long functions, remove duplication, simplify conditionals, and verify the refactor with tests.

Test Gen Expert helps write Python unit tests with AAA structure, clear naming, isolated fixtures, and correct mocking. Use it when generating or reviewing tests for normal, boundary, and error cases.
