Names the domain (documentation creation) and lists specific document types (PRD, ADR, Design Doc, Work Plan), but doesn't describe concrete actions beyond 'creation criteria' and 'templates'. It tells what types of documents but not what specific operations are performed on them.

Clearly answers both 'what' (documentation creation criteria including PRD, ADR, Design Doc, and Work Plan requirements with templates) and 'when' (Use when creating or reviewing technical documents, or determining which documents are required). The 'Use when' clause is explicit with multiple trigger scenarios.

Includes useful terms like 'PRD', 'ADR', 'Design Doc', 'Work Plan', 'technical documents', and 'templates', which users might naturally say. However, it misses common variations and synonyms like 'architecture decision record', 'product requirements', 'spec', 'RFC', 'proposal', or 'documentation template'.

The specific document types (PRD, ADR, Design Doc, Work Plan) help distinguish it, but 'technical documents' and 'documentation creation' are broad enough to potentially overlap with other writing or documentation skills. The 'reviewing' trigger could also conflict with code review or general review skills.

The skill is fairly dense with useful information, but includes some verbose sections that could be tightened—e.g., the detailed 'ADR Creation Conditions' rationale explanations, the extensive Design Doc section with YAML examples, and repeated scope boundary statements for each document type. Some of this is genuinely novel project-specific knowledge, but the document could be ~30% shorter without losing actionability.

The skill provides highly concrete, actionable guidance: a clear decision matrix for which documents to create, specific file paths and naming conventions, explicit structural requirements (e.g., required YAML blocks for Change Impact Map), template references, and precise conditions for ADR creation (e.g., '3+ levels', '3+ locations'). This is copy-paste ready for document creation workflows.

The Creation Process section provides a 4-step sequence (Problem Analysis → ADR Option Consideration → Creation → Approval), and the Decision Matrix shows creation order. However, there are no explicit validation checkpoints or feedback loops—e.g., no step to verify a PRD meets all required structural elements before proceeding to Design Doc, no error recovery guidance if approval is rejected. For a multi-document workflow with dependencies, this is a notable gap.

Excellent progressive disclosure structure: the skill provides a clear overview with a decision matrix up front, then detailed definitions for each document type, and references six separate template files for actual document creation. All references are one level deep and clearly signaled with consistent formatting and paths.
