Conciseness

The body is efficient and assumes Claude's competence (terse command lists, no explanations of basic concepts), with only minor trims possible: the opening line "You are a dependency sweeper agent. Scan for outdated and vulnerable packages." restates the description, and the untrusted-input block includes some general prompt-injection background. This fits anchor 4 rather than anchor 5, where every token earns its place with no redundancy at all.

Actionability

Concrete executable commands are given (`npm outdated` / `npm audit`, `cargo outdated` / `cargo audit`, `pip list --outdated`, `npm ci && npm test`), the classification is an explicit decision table, and the output target (`dependency-sweeper-state.md`) is named. It falls short of anchor 5 because "Lockfile analysis" is vague and no commands are given for actually performing updates per ecosystem.

Workflow Clarity

The scan → classify → output sequence is present and one validation checkpoint exists ("Run `npm ci && npm test` (or equivalent) before approving"), but the steps are presented as unordered sections rather than a sequenced workflow, and there is no feedback loop for what to do when validation fails (e.g. revert the update). This matches anchor 3 ('checkpoints missing or implicit') rather than anchor 4's 'clear sequence with most checkpoints present'.

Progressive Disclosure

The skill is under 50 lines, self-contained, and needs no external references, with well-organized, clearly headed sections (Scan Sources, Classification, Output, Rules, Untrusted input). Per the rubric's simple-skill guidance, this earns a 5 with just well-organized sections; no bundle files exist to reference, and the only path mention (`scripts/sync-untrusted-input.mjs`) is a generated-block provenance comment, not navigation.

Specificity

"Scan package manifests and lockfiles for outdated and vulnerable dependencies" and "Classify by severity and update type" name the domain plus two concrete actions, but coverage is not comprehensive (no applying updates, reporting, or named ecosystems). This matches anchor 3; it falls short of anchor 4, which expects several specific actions with only minor gaps.

Completeness

The description clearly answers 'what' (scan manifests/lockfiles, classify by severity and update type) but contains no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not a 2 because the 'what' is concrete and specific.

Trigger Term Quality

Terms like "outdated", "vulnerable", "dependencies", and "lockfiles" are natural keywords users would say, but common variations and synonyms are missing ("upgrade", "audit", "CVE", "security advisory", npm/cargo/pip). This fits anchor 3 rather than anchor 4's 'good keyword coverage; a few natural terms missing', since multiple common phrasings are absent.

Distinctiveness Conflict Risk

The dependency-scanning niche ("package manifests and lockfiles", "outdated and vulnerable dependencies") is mostly distinct from other skills with only minor overlap risk against generic package-update helpers. It is below anchor 5, whose examples pair the niche with explicit distinct trigger phrases that this description lacks.
