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 mentions reviewing and determining requirements but doesn't elaborate on specific capabilities like generating templates, validating structure, or checking completeness.

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 explicit 'Use when...' clause covers multiple trigger scenarios.

Includes strong natural keywords users would say: 'PRD', 'ADR', 'Design Doc', 'Work Plan', 'technical documents', 'templates', 'creating', 'reviewing'. These are terms users would naturally use when requesting help with these document types.

The specific document types (PRD, ADR, Design Doc, Work Plan) create a clear niche that is unlikely to conflict with other skills. The focus on documentation criteria and templates is distinct from general writing or coding skills.

The skill is fairly dense with useful reference information, but includes some sections that over-explain concepts Claude would already understand (e.g., explaining what a PRD or ADR is, defining 'Purpose' for each document type). Some sections like 'Three Elements of Task Completion Definition' and detailed ADR condition rationales add bulk without proportional value.

The decision matrix and ADR conditions provide concrete criteria for when to create documents, and storage paths/naming conventions are specific. However, the skill lacks executable examples—there are no concrete code commands, sample document snippets, or copy-paste ready content. The guidance is structured but remains at the level of descriptions and lists rather than executable steps.

The Creation Decision Matrix provides clear sequencing and the 4-step Creation Process outlines a workflow. However, validation checkpoints are weak—'Approval: Accepted after review enables implementation' is vague with no explicit verification criteria or feedback loops for catching errors in document creation. The phase division criteria are well-structured but lack explicit validation gates between phases.

Excellent progressive disclosure structure: the skill provides a clear overview with a decision matrix up front, then detailed definitions, and consistently links to 6 separate template files for actual document creation. References are one level deep and clearly signaled with both inline links and a summary table.
