Conciseness

The body is largely efficient — terse numbered playbooks, a compact platform table, and metrics with concrete thresholds ("Above 20% is healthy") — but the "Task-Specific Questions" section repeats four of the five questions from "Before You Start" nearly verbatim, and the flywheel/principles prose could be tightened slightly. This sits between 'mostly efficient but could be tightened' (3) and clearly efficient (4), noticeably above the midpoint.

Actionability

Guidance is concrete with specific numbers and tactics ("Recruit 20–50 founding members", "Pre-populate channels with 5–10 posts", "1% of members generate 90% of value") and defined output formats — actionable for an instruction-only skill. It stops short of fully executable level 5 because promised templates (welcome post, DM template, outreach template) are named as outputs but no example content or skeleton is provided.

Workflow Clarity

Each playbook is a clearly numbered 4–5 step sequence, and the overall arc (context → model selection → platform → playbook → metrics → output format) is coherent with explicit routing to the reference file. No destructive or batch operations apply, so no validation cap; it misses level 5 only because there are no explicit checkpoints (e.g., confirming which output format the user wants before producing it).

Progressive Disclosure

The single bundle file references/community-models.md exists, is referenced one level deep with a clear signal ("See references/community-models.md for:"), summarizes its contents in bullets, and includes routing guidance ("Route here when the user asks what kind of community..."). The split is appropriate — models/benchmark/scaling phases out, tactics inline — matching the 'clear overview with well-signaled one-level-deep references' anchor.

Specificity

The description lists multiple concrete actions — "create a community strategy", "grow a Discord or Slack community", "manage a forum or subreddit", "build brand advocates", "engage users post-signup", "turn customers into evangelists" — comprehensively covering the community-marketing domain in third person. It matches the 'lists multiple specific concrete actions; comprehensive coverage' anchor and exceeds the level-4 example, which shows only minor gaps in coverage.

Completeness

It explicitly answers both 'what' ("Build and leverage online communities to drive product growth and brand loyalty" with enumerated capabilities) and 'when' ("Use when the user wants to..." plus a dedicated "Trigger phrases:" list with concrete phrases). This mirrors the level-5 example structure exactly; level 4 would require the 'when' to be less explicit, which is not the case here.

Trigger Term Quality

An explicit trigger list provides comprehensive natural phrases users would actually say: "build a community", "Discord community", "community strategy", "brand advocates", "ambassador program", "grow our community", plus synonyms and platform variants (Slack, forum, subreddit, user community). Coverage including synonyms matches the level-5 anchor; nothing common is missing.

Distinctiveness Conflict Risk

The community-building niche is mostly distinct with clear triggers, but phrases like "ambassador program" and "brand advocates" overlap with closely related skills the body itself lists (e.g., referrals, social), creating minor conflict risk. It fits 'mostly distinct; minor overlap risk with closely related skills' rather than level 5's 'minimal conflict risk'.
