Conciseness

The doc-type checklists are compact and mostly earn their tokens (e.g., "Quick start (< 5 minutes to first success)", "Rollback steps", "Escalation path"), but roughly a fifth of the body — the entire Principles section ("Write for the reader", "Show, don't tell", "Don't bury the lede") — restates writing fundamentals Claude already knows. Not 2 because there is no padded prose or concept explanation; not 4 because the generic Principles block is more than a minor trim.

Actionability

The checklists give concrete, specific content requirements per doc type ("Rate limits and pagination", "Who to ask for what"), which is actionable for an instruction-only skill, but there is no template, skeleton, or example document showing what good output looks like, and no concrete procedure for producing one. Not 4 because nothing is copy-paste ready or exemplary; not 2 because the per-type bullets are specific instructions, not vague hints.

Workflow Clarity

There is no process at all — no steps for gathering source material, drafting, or verifying the result. The deliverable per doc type is clearly enumerated, which keeps this above score 2, but no sequence and no validation checkpoints (e.g., 'confirm code examples run before publishing', 'check links') exist, so it cannot reach 4. The destructive/batch cap does not apply since documentation is not a risky operation.

Progressive Disclosure

The body is under 50 lines with well-organized sections (## Document Types with ### per type, ## Principles) and no need for external references — no references/, scripts/, or assets/ exist — matching the guideline that a short, self-contained, well-sectioned skill scores 5 with no bundle files.

Specificity

The description names the domain ("technical documentation") with one action pair ("Write and maintain") plus a trigger-phrase enumeration ("API docs, architecture docs, or operational runbooks"), but never lists several concrete actions like a score-4 example ("Extracts text from PDF files, fills forms, converts pages to images"). It is above score 2 because the actions are not generic, and below 4 because the capability list is thin — 'maintain' is the only action beyond 'write'.

Completeness

It clearly answers both questions: what ("Write and maintain technical documentation") and when ("Trigger with 'write docs for', 'document this' ... or when the user needs help with any form of technical writing"), matching the anchor for explicit what-and-when with concrete trigger phrases. Not below 5 since the 'when' clause is explicit and phrase-level, not merely implied.

Trigger Term Quality

Natural phrases users would actually say are present: "write docs for", "document this", "create a README", "write a runbook", "onboarding guide". It falls short of score 5's 'comprehensive coverage including synonyms and file extensions' because common variations like "user guide", "how-to", "manual", or "technical writer" are missing.

Distinctiveness Conflict Risk

The niche (technical writing: READMEs, runbooks, architecture docs) is fairly distinct with specific triggers, but phrases like "document this" and "create a README" carry minor overlap risk with code-documentation or repo-init skills. Not 5 because the boundary between 'technical documentation' and code-comment/README-generation skills isn't sharply drawn; not 3 because the enumerated trigger phrases are much more specific than 'Works with document files'.
