by leeovery
"Build validated specifications from source material through collaborative refinement. Use when: (1) User asks to create/build a specification from source material, (2) User wants to validate and refine content before planning, (3) Converting source material (discussions, research, requirements) into standalone specifications, (4) User says 'specify this' or 'create a spec', (5) Need to filter hallucinations and enrich gaps before formal planning. Creates specifications in .workflows/specification/{topic}/specification.md that can be used to build implementation plans."
refactoring

dead-code-check
by cosmix
Generates dead code detection configurations for loom plan verification. Provides language-specific commands, fail patterns, and ignore patterns for Rust, TypeScript, Python, Go, and JavaScript. Use when adding code quality checks to acceptance criteria or truths fields in loom plans. Dead code detection catches incomplete wiring by identifying code that exists but is never called.
