Conciseness

The body is two lines — a generator comment and one instruction — with zero padding or over-explanation; every token earns its place. Matches the anchor-5 'lean and efficient' example; anchor 4 would require minor over-explanation to trim, and none is present.

Actionability

'Load and follow the shared skill at ~/.agents/skills/brainstorm/SKILL.md' is a concrete, executable instruction with a specific path, but it is the entire guidance — all actual task content lives in a file outside the bundle. This is a missing-key-details situation (anchor 3), not the minor gaps of anchor 4, since the skill itself carries no actionable content.

Workflow Clarity

The skill's own multi-step process (classify the request, explore options and risks, commit a numbered Decision, then a Plan) has no sequence, checkpoints, or validation steps anywhere in the body — only a delegation pointer. The clean, unambiguous delegation keeps it above the incoherent anchor 1, but no steps are listed, so it falls below anchor 3.

Progressive Disclosure

The single reference is clearly signaled and one level deep, but it points outside the skill bundle to ~/.agents/skills/brainstorm/SKILL.md (no references/, scripts/, or assets/ exist, and the path does not resolve in this environment), so the skill carries no content of its own and the pointer is unverifiable. Minimal structure with a non-bundled, environment-dependent dependency sits below anchor 3's 'could be better organized'.

Specificity

Lists several specific actions — 'classify the request', 'explore options and risks through dialogue', 'commit a numbered Decision' — matching anchor 4's 'several specific actions; minor gaps'. Not anchor 5 because 'Conventional Docs Decision' is unexplained jargon and the downstream stages ('review, prototypes, and acceptance move through') are gestured at rather than specified; above anchor 3 because more than 1–2 concrete actions are named.

Completeness

Explicitly answers both what ('classify the request, explore options and risks through dialogue, then commit a numbered Decision that review, prototypes, and acceptance move through') and when ('Use PROACTIVELY before any creative work — new features, new subsystems, interface or dependency changes, or any open-ended design question') with concrete quoted trigger phrases. This matches the anchor-5 pattern exactly; anchor 4 would require the 'when' clause to be less explicit.

Trigger Term Quality

Provides comprehensive natural-phrase coverage: 'what are the options', 'how should I approach', 'should I use X or Y', 'help me decide', 'write a decision', 'ADR', plus proactive triggers like 'new features' and 'interface or dependency changes'. These are exactly the phrases a user would say when needing this skill; anchor 4 would require missing natural terms or synonyms, and none are missing for this domain.

Distinctiveness Conflict Risk

The decision-record framing ('numbered Decision', 'write a decision', 'ADR') establishes a clear niche with distinct triggers, but 'before any creative work' and 'how should I approach' are broad enough to overlap with general planning or architecture skills. Mostly distinct with minor overlap risk against closely related skills (anchor 4) rather than the minimal conflict risk of anchor 5.
