Names the domain (PRD and Design Docs) and mentions a workflow (discovery, generation, verification, review), but doesn't list specific concrete actions like 'analyze code structure', 'extract API contracts', or 'document architecture decisions'.

Describes what it does (generate PRD and Design Docs from codebase) but has no explicit 'Use when...' clause or trigger guidance. Per the rubric, a missing 'Use when...' clause caps completeness at 2, and the 'when' is entirely absent here, making it a weak 1-2; scoring 1 because the when is completely missing.

Includes relevant terms like 'PRD', 'Design Docs', and 'codebase', which users might naturally say. However, it misses common variations like 'product requirements document', 'technical design document', 'TDD', 'spec', 'specification', 'documentation from code', or 'reverse engineer docs'.

The combination of PRD/Design Docs from an existing codebase is somewhat distinctive, but 'design docs' and 'documentation' could overlap with general documentation skills. The lack of explicit trigger boundaries increases conflict risk.

The skill is lengthy but most content is necessary for the complex multi-phase orchestration workflow. However, there's some redundancy — the fullstack mode patterns repeat similar invocation blocks with minor variations, and some explanations (like 'No additional discovery required') could be trimmed. The agent invocation blocks are well-structured but verbose.

Every step includes concrete agent invocation blocks with specific subagent_type, description, and prompt templates. Quality gates have explicit numeric thresholds (consistencyScore >= 70, verifiableClaimCount >= 20), trigger conditions are clearly enumerated, and variable passing ($STEP_N_OUTPUT) is explicit throughout. The workflow is copy-paste ready for an orchestrator agent.

The workflow is exceptionally well-sequenced with explicit quality gates at Steps 3 and 8, feedback loops for revision (Steps 5 and 10 with max 2 cycles), human review checkpoints, unit completion checklists, and clear error handling table. The sequential dependency chain (each step's output feeds the next) is clearly documented, and validation is built into every phase.

The content is a monolithic document (~250 lines) with no references to external files for detailed sub-agent specifications, prompt templates, or examples. The workflow overview section provides a good high-level map, but the fullstack mode variations and per-step agent invocations could be split into separate reference files. No bundle files are provided to support progressive disclosure.
