Shared research skill. Performs structured web search, codebase analysis, and package registry lookups. Dispatched as a subagent by any coordinator agent.

Extracts API endpoints, function signatures, public interfaces, and type contracts from legacy code

Extracts system architecture, component design, dependency graphs, deployment topology, and tech stack from legacy code

Assembles extracted data into final SDD-compatible 18-section specifications at global, project, and module levels

Infers functional requirements, business rules, validation logic, workflows, and user stories from legacy code behavior

Extracts error handling patterns, security mechanisms, logging, configuration, and non-functional requirements from legacy code

Extracts data models, entity schemas, relationships, validation rules, and state machines from legacy code

Scans a legacy codebase to identify projects, modules, technology stack, boundaries, and produces a structured discovery manifest

Analyzes existing tests to extract behavior contracts, acceptance scenarios, coverage mapping, and test-derived requirements

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.

Pre-planning spec completeness validation. Checks obligation language, error behaviors, data model depth, API contracts, state machines, traceability, integrations, artifact consistency, and security requirements.

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.
