API reference documentation skill. Produces and updates API endpoint documentation from contract files in .sdd/docs/api-reference.md.

Architecture documentation skill. Produces and updates architecture overview, component diagrams, technology stack, design decisions, and directory structure in .sdd/docs/architecture.md.

Changelog documentation skill. Prepends changelog entries for approved work packages to .sdd/docs/CHANGELOG.md with WP identifier, date, changes, and breaking changes.

Architecture adherence review skill. Evaluates component design, tech stack compliance, directory structure, SOLID principles, dependency direction, and scope discipline.

Dependency review skill. Checks for known CVEs, abandoned packages, unnecessary dependencies, license compatibility, version pinning, and supply chain integrity.

Documentation accuracy review skill. Compares .sdd/docs/ content against implementation for accuracy, completeness, and staleness.

Performance review skill. Detects N+1 queries, missing indexes, blocking in async contexts, unbounded data fetching, unnecessary computation, inefficient data structures, and missing caching opportunities.

Code quality review skill. Evaluates readability, complexity, naming, comments, error handling, style consistency, dead code, and duplication.

Security review skill. Audits implementation against all 14 OWASP Secure Coding Practices categories. Cross-references spec security requirements. Uses web research to verify unfamiliar patterns.

Spec adherence review skill. Evaluates implementation against functional requirements, success criteria, and acceptance scenarios from the specification. Verifies SHALL obligations, preconditions, postconditions, error paths, edge cases, data models, and API contracts.

Test quality review skill. Evaluates test validity, coverage thresholds, BDD scenario matching, edge cases, test structure, and error path testing.

Analyze pending code changes and commit them in semantically grouped commits. Use when: committing code, grouping changes, splitting commits, organizing staged files, preparing atomic commits. Enforces that each commit is a single coherent unit of work -- functionally and technically meaningful.
