Conciseness

The ~27-line body is lean, assumes Claude's competence, and explains nothing Claude already knows. Minor trim opportunities keep it from anchor 5: the opening line restates the description verbatim, and the "Keywords" section duplicates the "When to use" list in a spot that adds little for execution.

Actionability

The routing is concrete and executable: named files ("examples/3p-updates.md", "examples/company-newsletter.md", etc.) each mapped to a communication type, plus a defined fallback ("ask for clarification"). It falls short of anchor 5 because no inline example or format guidance exists — all substantive instruction is deferred to the example files.

Workflow Clarity

The three-step sequence (identify type → load guideline file → follow its instructions) with a fallback is clear and coherent, and no validation is needed for this non-destructive task. It misses anchor 5 because four of the seven listed use cases (status reports, leadership updates, project updates, incident reports) have no explicit file mapping — the reader must infer the general-comms.md catch-all.

Progressive Disclosure

The structure is textbook progressive disclosure: clear sections, one-level-deep references each labeled with its purpose, matching the anchor-5 shape. However, scoring against the actual bundle, none of the four referenced `examples/*.md` files exist in the skill directory, so the well-signaled navigation dead-ends — a gap that keeps it at anchor 4.

Specificity

The description is "To write internal communications, use this skill for:" — it names the domain but offers only the single generic action "write" and then truncates with nothing after the colon. This matches anchor 2 ("Names the domain but actions are minimal or generic", e.g. "Processes PDF files") and lacks the 1-2 concrete actions needed for anchor 3.

Completeness

The "what" is thin — it never says which communication types it covers because the sentence ends at "for:" — and there is no "when"/trigger clause at all ("use this skill for:" is not an explicit use-when condition). This fits anchor 2 (vague what, no when); anchor 3 would require a clearly specified set of concrete actions.

Trigger Term Quality

The only natural keyword is "internal communications", which is the core phrase a user might say, but common variations and synonyms ("internal comms", "newsletter", "weekly update", "3P update") are entirely absent. It has some relevance beyond anchor 2's generic keywords but not the coverage of anchor 4.

Distinctiveness Conflict Risk

"Internal communications" is a recognizable niche, but with no named communication types, actions, or distinguishing triggers, the description could plausibly be claimed by generic business-writing or document skills. Anchor 4 would require more distinct trigger surface than a bare domain name provides.
