Conciseness

The body is dense and project-specific throughout — classification tables, word limits, and exact file paths with almost no explanation of concepts Claude already knows. Minor trimmable padding exists: the anecdote in the trap section ("One pass found them in two rounds. A grep found five...") and a few justification asides ("Consequences worth knowing") keep it at the 4 anchor rather than 5.

Actionability

Fully executable guidance: exact diff command ("git diff <base>" with the explicit anti-pattern), a runnable AST-comparison snippet, concrete grep patterns ("match=", "in str(exc", "in str(reject"), make targets, line-length and word-count limits, and a per-group file map. Copy-paste-ready with specific examples covering the common cases, matching the 5 anchor.

Workflow Clarity

A clear three-phase workflow (Audit → Apply → Verify) with an explicit hard checkpoint ("Stop. Wait for approval."), a two-phase apply split with rationale, and five concrete verification steps including feedback loops ("Explain every file that appears", "Run the suites anyway. The grep is a head start, not the check"). This matches the 5 anchor's explicit validation steps and error-recovery loops; batch-edit operations with real verification cannot score higher.

Progressive Disclosure

Structure is excellent: the 53 STE rules, use cases, and all nine vocabulary groups plus adding-terms live one level deep in references/ and every referenced file exists, with a table indexing exactly when to read each group. Two minor gaps keep it at 4: references/simple-english-checklist.md exists in the bundle but is never referenced from the body, and the cross-group legal-noun lists are inlined in SKILL.md where the pattern established elsewhere would put them in a reference file.

Specificity

"Review and rewrite the prose a branch adds" names two concrete actions, enumerates the concrete artifacts ("docstrings, comments, user-facing messages, docs"), and names the two governing standards ("dlt's fixed vocabulary and Simplified Technical English") — comprehensive and concrete, matching the 5 anchor's multiple specific actions with full coverage. It does not fall to 4 because there are no minor gaps in the artifact enumeration.

Completeness

The 'what' is explicit and concrete; the 'when' is present as "Invoke as /review-vocabulary", which is explicit invocation guidance but not a trigger-phrase-style 'Use when...' clause, so it matches the 4 anchor ('when' could be more explicit). Not 3, because the rubric's cap applies to a missing or only weakly implied 'when' — here the invocation condition is stated, and the skill is maintainer-invoked by design.

Trigger Term Quality

Good natural-term coverage: "docstrings", "comments", "user-facing messages", "docs", "prose", "branch", "vocabulary" are phrases a maintainer would actually say. It misses a few common synonyms such as "error messages", "documentation", or "naming" that would round out coverage, so it sits at the 4 anchor rather than 5.

Distinctiveness Conflict Risk

"dlt's fixed vocabulary and Simplified Technical English" ties the skill to one project's house style, and "the prose a branch adds" scopes it to a diff review — a clear niche with distinct triggers and minimal conflict risk with generic review or docs skills.
