Conciseness

The body is table-driven and assumes Claude's competence — no space is spent explaining concepts Claude already knows. Minor trimmable duplication exists: the intro paragraph repeats the frontmatter description, and reference links appear both inline per phase and again in the final 'Reference Files' table. This matches 'efficient; minor instances of over-explanation that could be trimmed' rather than 5's 'every token earns its place'.

Actionability

Guidance is fully executable: exact playbook path (`.claude/team-update-playbook.md`), copy-paste commands (`git log --oneline --since=<last-update>`, `git rev-parse --is-inside-work-tree`), a 6-question preference checklist, a default triage table, and concrete example output blocks (Feedback Summary, Suggested Priorities). Not 4 — there are no missing key details or vague-only steps in the body.

Workflow Clarity

The workflow is a clearly sequenced phase chain (0, 0b, 1, 2, 3, 4) with explicit validation checkpoints — 'APPROVAL REQUIRED' gates at 2b and 3c, draft preview before posting, and fallbacks via graceful degradation. The operating-modes table maps each trigger to a phase subset. This matches the top anchor with explicit validation steps rather than 4's 'minor validation gaps'.

Progressive Disclosure

The body is an orchestration overview; all detail (detection patterns, playbook template, message composition, triage classification) is split across four real reference files, well-signaled inline at point of use, and summarized in a navigation table. Verified against the actual bundle: references are exactly one level deep with no reference pointing to another file.

Specificity

The description lists multiple concrete actions — 'Post project updates to team chat, gather feedback, triage responses, and plan next steps' plus 'discovers tools and saves a playbook' — covering the skill's full workflow comprehensively. It exceeds the 'minor gaps' level of 4 because no significant capability is unnamed.

Completeness

Both 'what' (post, gather, triage, plan, plus first-run playbook behavior) and 'when' ('Trigger with ...') are explicitly and clearly stated with concrete trigger phrases. The missing-trigger-guidance cap of 3 does not apply since explicit trigger guidance is present.

Trigger Term Quality

Eight natural trigger phrases including synonyms and colloquial forms users would actually say: 'team update', 'post update', 'sync with team', 'standup', 'check team chat', 'feedback loop', 'project update', 'what did the team say'. This matches comprehensive synonym coverage rather than 4's 'a few natural terms missing'.

Distinctiveness Conflict Risk

A clear team-communication niche with mostly distinctive triggers ('check team chat', 'what did the team say', 'sync with team'), but 'post update' and 'feedback loop' are somewhat generic and could overlap with unrelated skills — minor overlap risk, so it sits between the 4 and 5 anchors, closer to 4.
