Conciseness

Lean body with no concept-explanation padding; every rule earns its place and Claude's competence is assumed ('No "Welcome to...", no history', 'no superlatives'), matching the lean-and-efficient top anchor.

Actionability

Concrete, specific guidance for an instruction-only skill ('one section per component/layer, in data-flow order ... env file to copy, required vars, dev command', 'point to .env.example', 'bold component paths'); absence of copy-paste code is acceptable here, but it stops short of fully executable examples, so below 5.

Workflow Clarity

A clear numbered construction sequence (Title+tagline → diagram → per-component sections → commands → license) with an explicit verification rule ('Every claim must be verifiable in the repo: check ... before writing setup steps'), but validation is framed as a standing rule rather than an explicit checkpoint step inside the sequence.

Progressive Disclosure

Under 50 lines with no need for external bundle files and two well-organized sections (Structure, Rules); per the simple-skill note this earns the top score on structure alone.

Specificity

Names the domain ('READMEs and project documentation') and a couple of concrete actions ('writing and updating') but does not enumerate several distinct actions, so it matches the 'domain + 1-2 actions, not comprehensive' anchor rather than the several-action anchor at 4.

Completeness

Explicitly answers both what ('Conventions for writing and updating READMEs and project documentation in this repo') and when ('Load when creating or editing a README, docs page, or component-level documentation') with concrete trigger phrases, matching the top anchor.

Trigger Term Quality

Includes natural terms a user would say ('README', 'docs page', 'creating or editing', 'component-level documentation'); good coverage but misses common synonyms like 'documentation' as a standalone trigger, so below the comprehensive 5.

Distinctiveness Conflict Risk

Scoped to README/docs style for this specific repo with reference models named, making it mostly distinct; minor overlap risk remains with general documentation skills, so not a clean niche 5.
