Conciseness

Mostly efficient — the path taxonomy, ratchet rule, just-in-time companion offer, and spec self-review are genuinely skill-specific — but the approval-gate rule is restated at least six times (HARD-GATE block, Anti-Pattern section, 7-row Red Flags table, checklist items, 'Terminal states are path-bound'), and 'Design for isolation and clarity' / 'Working in existing codebases' restate general software judgment Claude already has. Not 2 because the majority of the body is original policy rather than padding; not 4 because the gate repetition and generic design sections are noticeable.

Actionability

Concrete and executable for an instruction skill: per-path numbered checklists, copy-paste message templates (the companion offer, the user-review-gate prompt), an exact spec path pattern, and explicit decision tests ('would the user understand this better by seeing it than reading it?'). Not 5 because 'start the server with --open' never names the actual script, even though scripts/start-server.sh exists in the bundle.

Workflow Clarity

Clear sequences for all three paths with explicit validation checkpoints (approval gates, spec self-review, user review gate) and feedback loops for error recovery ('User approves design? no, revise'; spec self-review fix-inline; re-run review on requested changes), plus a flow diagram and checklists. Not 4 because no checkpoint gaps remain — the approval/review gates are exactly the validation the anchor-4 example lacks.

Progressive Disclosure

Section structure and headers are good, but scored against the actual bundle: the single external reference 'skills/brainstorming/visual-companion.md' does not exist in the bundle, and none of the five scripts/ files (server.cjs, helper.js, start-server.sh, stop-server.sh, frame-template.html) are referenced or navigable from the body. Not 4 because a broken reference and an unlinked scripts directory are more than minor organization gaps; not 2 because the body itself is well-organized with clearly signaled sections and nothing is buried two levels deep.

Specificity

Base score is 3 — it names the pre-implementation design domain and 1-2 actions ('Explores user intent, requirements and design') but no comprehensive action list. The rubric's third-person voice rule applies ('You MUST use this' is second person), reducing specificity by 1 to 2. It is not 1 because it is not pure abstraction like 'Helps with documents'.

Completeness

Both 'what' ('Explores user intent, requirements and design before implementation') and 'when' (explicit trigger guidance covering creative work types) are present. Not 5 because the 'what' is a single thin sentence that doesn't enumerate concrete deliverables (approaches, design doc, spec); not 3 because the 'when' clause is explicit, so the completeness cap for missing trigger guidance doesn't apply.

Trigger Term Quality

'creating features, building components, adding functionality, or modifying behavior' are natural phrases users actually say, giving good keyword coverage. Not 5 because common synonyms and variations ('design', 'brainstorm', 'new project', 'spec') are missing; not 3 because coverage clearly exceeds 'some relevant keywords'.

Distinctiveness Conflict Risk

'before any creative work - ... or modifying behavior' claims to gate virtually every code-change request, creating high overlap risk with writing-plans and any implementation or planning skill. Not 1 because the design-before-implementation niche is real; not 3 because the trigger surface ('any creative work', 'modifying behavior') is broad enough to fire on nearly every task.
