Conciseness

The body is dense and imperative with no explanations of concepts Claude already knows, but crest-inline guidance is stated three times — workflow step 4 ("Inline the canonical detailed Tranmere crest fragment"), the SVG rule ("Prefer the repository's detailed canonical tranmere-crest group"), and "Copy the complete crest group into every kit SVG" — which could be consolidated. This is 'efficient with minor trimming possible' (anchor 4), not the fully lean anchor 5.

Actionability

Mostly executable guidance: exact asset paths ("packages/site/public/builder/kits/home/<kit-id>.svg"), an exact copy-paste render route with parameters, a specific selector file ("packages/site/components/apps/PlayerAvatarBuilder.tsx"), and a concrete build command ("yarn workspace @tranmere-web/site build"). Minor gaps keep it at 4: 'Format changed TypeScript files' omits the actual command, and 'Inspect the supplied reference image with the image viewer' names no specific tool — the anchor-5 'fully executable, covers common cases' bar is not quite met.

Workflow Clarity

The 11-step workflow is clearly sequenced with an explicit feedback loop (render at the given route in step 9, 'Compare the complete avatar with the reference. Iterate' in step 10) and a dedicated Validation section that functions as a checklist (selector option, standalone SVG loads, composed route renders, crest inlined with no external references, plus a build command). This matches the anchor-5 sequence with explicit validation and error-recovery iteration, exceeding the 4 anchor's 'minor validation gaps'.

Progressive Disclosure

SKILL.md holds the operational workflow while format specifics (composition order, key paths, the canonical crest fragment, canvas landmarks, naming) are appropriately split into a single real, one-level-deep reference, well signaled at the point of need ("Read [references/kit-format.md] before creating or substantially restructuring artwork"). Scoring against the actual bundle confirms the reference exists and contains no further nested references, matching the clear-overview anchor 5.

Specificity

The description lists multiple concrete actions — "Create, edit, and integrate Tranmere Rovers kit SVGs" — and enumerates specific concrete sub-tasks ("adding a home, away, third, or goalkeeper shirt", "correcting kit colours, stripes, collars, sponsors, crests, manufacturers, cuffs, or alignment", "adding a season to the kit selector", "validating a kit through the /builder/... SVG route"). Coverage is comprehensive with no generic filler, matching the score-5 anchor rather than the 4 anchor, which expects minor gaps.

Completeness

Both questions are answered explicitly: the 'what' is stated first ("Create, edit, and integrate Tranmere Rovers kit SVGs for this repository's player avatar builder") and the 'when' is a full "Use when..." clause with multiple concrete trigger scenarios. This matches the score-5 exemplar structure exactly, not the 4 anchor where the 'when' is only loosely specified.

Trigger Term Quality

Natural phrases users would say are covered comprehensively: shirt types (home, away, third, goalkeeper), concrete kit components as synonyms (colours, stripes, collars, sponsors, crests, manufacturers, cuffs, alignment), the format keyword ("kit SVGs"), the product surface ("player avatar builder", "kit selector"), and a route pattern ("/builder/... SVG route"). This fits the comprehensive-coverage anchor including synonyms; it is well above the 4 anchor's 'a few natural terms missing'.

Distinctiveness Conflict Risk

The description is tightly scoped to a clear niche ("Tranmere Rovers kit SVGs", "this repository's player avatar builder", "/builder/... SVG route"), so it would not fire for generic SVG, image-editing, or football-related skills. Minimal conflict risk, matching the clear-niche anchor rather than the 4 anchor's minor overlap risk.
