The body is mostly efficient and avoids explaining concepts Claude already knows, but some sections are padded — the fully worked example tables in Phase 3 and the verbatim vendor email template add tokens that are illustrative rather than strictly necessary. Not a level 3 'every token earns its place', but tighter than the level-1 verbose anchor.

Provides concrete, executable tool calls like 'mcp_snyk_snyk_sbom_scan(file="path/to/sbom.json", severity_threshold="medium")' and runnable CLI commands (snyk sbom --format=cyclonedx1.5+json), plus copy-paste report templates — fully executable guidance.

A clear five-step Quick Start sequence plus phased steps (validation → scan → analysis → remediation) with explicit validation in Phase 1 and a dedicated Error Handling section providing fix-and-retry feedback loops, matching the top anchor.

A references/sbom-formats.md file exists and is real, but the SKILL.md body never signals or links to it (no 'See references/sbom-formats.md'), so the detailed format examples are inlined in the body rather than split out. Structure is present and one-level-deep but not clearly signaled, fitting the mid anchor.

Lists multiple concrete actions: 'vulnerability assessment', 'third-party risk management', 'Validates SBOMs from vendors', 'generates SBOMs for internal projects', matching the top anchor for naming specific concrete actions.

Explicitly answers 'what' (vulnerability assessment and risk management; validates/generates SBOMs) and 'when' via an explicit 'Use this skill when:' clause with five bullet triggers, satisfying the top anchor.

Covers natural terms users would say including 'SBOM file', 'third-party risk', 'vendor security', 'check SBOM for vulnerabilities', 'CycloneDX or SPDX formats' — good coverage of phrasings a user would naturally invoke.

The SBOM/vulnerability/CycloneDX/SPDX niche with distinct triggers is clearly separated from general security or file skills, making mis-triggering unlikely.
