Conciseness

The body is information-dense rather than tutorial-style (no 'what is a lockfile' padding), but it contains several padded/boilerplate sections: routing guidance is repeated three times (frontmatter description, 'Purpose and activation' listing sibling skills, and again in 'Routing Boundary'), the 'Base Framework' section carries a policy-link manifest plus precedence boilerplate, and 'Optional Workflow Integration' spends ~8 lines on integration for a skill that declares itself 'fully standalone'. This matches the score-3 anchor 'Mostly efficient but includes some unnecessary explanation or could be tightened'; it is not score 4 because these redundancies are structural sections to trim, not minor instances, and not score 2 because the core guidance itself is terse, expert-level, and free of concept explanations Claude already knows.

Actionability

For an instruction-only analysis skill, the guidance is concrete throughout: precise inspection targets ('manifest-lock alignment, declared/imported/missing/wrong-scope packages, duplicate/conflicting/peer versions'), a verbatim copy-paste-ready output template ('Use this exact structure'), an exact findings-field list ('ID, category, severity, confidence, exact location/path/version/graph edge...'), and executable tool names delegated to the real references/ecosystem-tools.md (npm ls, pip-audit, go mod graph). This matches the score-4 anchor 'Mostly executable guidance... minor gaps'. It falls short of score 5 because no example commands or worked micro-examples appear inline in the body, and one heading is garbled ('Diagnose package, build, and weight risk' appears to mean 'dependency-weight risk'), which slightly muddies execution.

Workflow Clarity

The five workflow steps are clearly sequenced (scope/inventory -> build graphs -> package risk -> architecture/runtime -> supply chain/upgrade readiness) each with concrete inputs, and validation checkpoints exist: 'Verify unused candidates across all non-static use sites before removal', evidence-gating severity ('Use HIGH only with direct manifests/locks/imports/scanners/config/runtime evidence'), 'Unable to determine - evidence needed' as an explicit no-evidence outcome, and a final quality checklist. This matches the score-4 anchor 'Clear sequence with most checkpoints present; minor validation gaps'. Not score 5 because checkpoints are distributed in prose rather than attached as explicit per-step gates, and there is no validate-then-proceed loop inside any step; not score 3 because validation is clearly articulated, and the skill's destructive operations (auto-removal, mass upgrade) are explicitly prohibited with required test/rollback plans.

Progressive Disclosure

Per the guideline to score against the actual bundle structure: the four references/ files (ecosystem-tools.md, risk-and-upgrades.md, architecture-and-runtime.md, examples.md) exist, are well-signaled with markdown links at the relevant workflow step, and are one level deep — good. However, ten referenced paths do not exist in the bundle: all nine shared/base/* policy files linked as 'Required packaged policies' and shared/workflow-contract.md are missing, so navigation breaks for a third of the body's links. This fits the score-3 anchor 'Some structure but could be better organized' — the structure and signaling are present but the bundle does not resolve its own required references. Not score 2 because substantial, genuinely well-split reference files exist and the body itself is sectioned; not score 4 because unresolved required-policy links are more than a minor organization gap.

Specificity

Quotes: "Analyze package, lockfile, import/module, build, runtime-service, and third-party dependency relationships, risks, upgrades, and supply-chain health" — this names several concrete analysis targets (relationships, risks, upgrades, supply-chain health) across multiple dependency types, matching the score-4 anchor 'Lists several specific actions; minor gaps in coverage'. It falls short of the score-5 anchor because the action set rests on a single verb ('Analyze') rather than multiple distinct concrete actions, and it is not above 4 since coverage of the domain is genuinely broad with only minor gaps.

Completeness

Quotes: what — "Analyze package, lockfile, ... dependency relationships, risks, upgrades, and supply-chain health"; when — "Use when dependencies themselves are the primary object. Do not use for a broad security audit or whole-architecture review." Both 'what' and an explicit 'Use when...' trigger are present, so it is above the score-3 cap. It sits at score 4 rather than 5 because the 'when' clause is stated abstractly ('dependencies themselves are the primary object') instead of concrete user-side trigger phrases like 'when the user mentions lockfiles or asks about upgrades', though the paired exclusion clause partially compensates.

Trigger Term Quality

Quotes: "package", "lockfile", "dependency", "upgrades", "supply-chain", "import/module" — these are natural words a user would say when needing this skill ('analyze my dependencies', 'check the lockfile', 'is it safe to upgrade'). It matches the score-4 anchor 'Good keyword coverage; a few natural terms missing': common variations users actually say are absent, e.g. ecosystem names (npm, pip, Maven), 'outdated/abandoned packages', 'transitive dependencies', and file extensions like package.json or requirements.txt. Not score 5 for that reason; clearly above score 3 because the core natural terms are all present.

Distinctiveness Conflict Risk

Quotes: "Do not use for a broad security audit or whole-architecture review" combined with the niche framing "Use when dependencies themselves are the primary object". This carves a clear niche (dependency-centric analysis) and explicitly redirects the two most confusable neighboring skills (security audit, architecture review), matching the score-5 anchor 'Clear niche with distinct triggers; minimal conflict risk'. Neighboring anchor 4 ('minor overlap risk') is a worse fit since the exclusions address exactly those overlaps.
