Mostly efficient and free of concept-explanation fluff, but the manifest-filename list is duplicated between the frontmatter and the body's language table, and the Mode A branching prose (reachability sub-bullets) could be tightened — keeping it just short of fully lean.

Provides exact, copy-paste-ready commands ('echo '<json-array>' | npx @meterian/cli check', 'npx @meterian/cli advisories get <language> <name> <version>'), concrete version-extraction rules, a fixed five-column output format, and remediation commands like 'npm install lodash@4.17.21'.

Modes A and C are clearly sequenced, and Mode C includes an explicit validate→fix→retry loop ('After applying all fixes, re-run the full audit... If new vulnerabilities are found, repeat') plus a confirmation checkpoint before Minor/Major bumps.

No bundle files exist and none are needed; the single-file body is well-organized into clearly headed sections (Language Parameter Reference, Mode A/B/C) with no nested references, which the rubric allows to score 3.

Lists multiple concrete actions ('dependency audit, vulnerability scan, package safety check, pre-deployment/compliance security review... remediation of insecure packages'), which would rate a 3, but the opening 'Activate for ANY...' uses imperative/second-person voice directed at Claude, triggering the rubric's 1-point specificity penalty.

Explicitly answers both what (Meterian CLI scanning with a shared cross-language advisory database) and when ('Activate for ANY...' and 'activates automatically when the user opens or modifies a manifest file').

Strong coverage of natural phrasings a user would actually say: 'is [library] [version] safe?', 'dependency audit', 'vulnerability scan', 'package safety check', plus concrete manifest filenames like package.json and Cargo.toml.

Occupies a clear niche — third-party package/dependency security auditing tied to a named tool and specific manifest-file triggers — making it unlikely to fire for unrelated skills.
