Conciseness

The body is mostly lean — phase goals, tool field listings, and templates all earn their place — but 'Step 2.2: Review Tool Results' largely repeats the field list already given in Step 2.1, and the Quick Start slightly duplicates the phase overview. This fits anchor 4 ('minor instances of over-explanation that could be trimmed') rather than 5, but is well above anchor 3's 'several unnecessary explanations'.

Actionability

Guidance is fully concrete: it names the exact tool ('snyk_package_health_check'), its arguments (name, version, ecosystem), the returned fields with their possible values, hard disqualifier criteria, and a copy-paste-ready comparison table and warning template. This matches anchor 5's 'copy-paste ready... specific examples cover the common cases', including the no-secure-option and error scenarios.

Workflow Clarity

A clear four-phase sequence with a Quick Start summary, explicit validation checkpoints (the disqualifiers in Step 2.3), and feedback loops for error recovery ('Retry once; if still no data, fall back to manual research'; report partial results with disclaimer). This matches anchor 5; the operations are read-only health checks, so the destructive/batch validation cap does not apply.

Progressive Disclosure

The body is well-sectioned, but the bundle's reference file (references/package-evaluation-criteria.md) is never mentioned or linked anywhere in SKILL.md — a buried reference the agent would only find by listing files. Additionally, evaluation criteria (disqualifiers vs. the reference's Red Flags Checklist, decision thresholds) are duplicated between body and reference. This matches anchor 3 ('references present but not clearly signaled; content that should be separate is inline'); anchor 4 requires references to be 'mostly clear', which an unlinked reference is not.

Specificity

The description enumerates multiple concrete evaluation actions — 'evaluating vulnerability status, maintenance health, popularity, community, and security posture' — giving comprehensive coverage of the package-selection domain. It exceeds anchor 4 because no meaningful evaluation dimension is missing, and is far above anchor 3's '1-2 concrete actions'.

Completeness

It explicitly answers both what ('Helps choose secure, healthy open-source packages by evaluating...') and when ('Use this skill when:' followed by six concrete trigger conditions). This mirrors anchor 5's example structure exactly; anchor 4 would need a weaker or less explicit 'when' clause, which is not the case here.

Trigger Term Quality

Natural user phrasings are comprehensively covered with synonyms: 'which package should I use for X?', 'is this package safe?', 'secure alternative', 'compare packages (A vs B)', 'dependency health', 'package chooser', 'package security'. It matches anchor 5's requirement for natural terms and synonyms; anchor 4 would require a noticeably missing common phrase, and none is.

Distinctiveness Conflict Risk

It occupies a clear niche (secure open-source package selection) with distinct triggers like 'is this package safe?' and 'package chooser' that few other skills would claim. Anchor 5 fits; anchor 4's 'minor overlap risk with closely related skills' does not apply since the trigger phrasing is specific to dependency/package evaluation.
