Conciseness

The body is 8 lines with zero padding: it states two delegation directives and one conditional substitution rule, assuming Claude's competence throughout. Every token earns its place, matching the anchor-5 lean example; there is nothing to trim and no over-explanation.

Actionability

Guidance is concrete and executable: exact file paths (`.claude/skills/onboarding/SKILL.md`, `.agents/rules/cog.md`, `.agents/agents/<name>.md`), an exact mechanism (`invoke_subagent`), and an unambiguous substitution rule. Not 5 because the substantive steps themselves live in an external file not present in the bundle, so the body alone does not cover the common execution cases.

Workflow Clarity

The sequence is clear and correctly ordered: execute the authoritative playbook, then follow `.agents/rules/cog.md`, with an explicit conditional for agent-worker delegation. As a single-purpose skill under 50 lines with no destructive or batch operations, no validation checkpoints are required; the minor gap keeping it at 4 (not 5) is the absence of any handling for the referenced files being missing.

Progressive Disclosure

References are explicitly named rather than buried, but the body delegates everything through a chain (this SKILL.md → an external SKILL.md playbook → per-agent files plus a rules file), which adds reference depth and depends on paths outside the bundle that cannot be verified. This matches anchor 3 (some structure, references present but organization could be better) rather than 4, since the navigation chain is not one clearly-signaled level deep.

Specificity

"creates profile, interests, and watchlist files" lists several concrete artifacts and "guided setup" names the mode of operation, matching anchor 4 (several specific actions, minor gaps). Not 5 because "Personalize COG for your workflow" stays domain-level without comprehensively covering what the setup touches.

Completeness

The "what" is clear ("Personalize COG... creates profile, interests, and watchlist files with guided setup"), but the "when" is only weakly implied by "(run this first!)", which is an ordering hint rather than an explicit trigger clause. Per the guideline, a missing "Use when..." clause or equivalent caps completeness at 3; it is above 2 because the what is concrete, not vague.

Trigger Term Quality

Relevant keywords like "profile", "interests", "watchlist", and "guided setup" are present, but natural user phrasings such as "onboarding", "set up", "get started", or "configure" are missing. Matches anchor 3 (some relevant keywords, missing common variations) rather than 4, which requires good coverage with only a few terms missing.

Distinctiveness Conflict Risk

"COG" names a distinct system and "watchlist" is a fairly niche artifact, giving a mostly distinct identity with minor overlap risk against generic setup/personalization skills. Not 5 because terms like "personalize" and "profile" could still collide with other onboarding-type skills.
