Mostly lean (numbered steps, command blocks, tables) but the Overview over-explains what OpenVEX/VEX is — a concept a competent model largely knows — and some prose could be trimmed.

Provides fully executable commands (go install, vexctl create/merge/attest with concrete flags), jq validation queries, a CI YAML block, and a copy-paste-ready worked example with an exact purl.

A clear 9-step sequence with an explicit Step 7 validation checklist plus a jq feedback loop, a CI fail-on-missing-justification gate, and a vexctl filter preview step before committing.

A single self-contained SKILL.md with well-organized sections (When to use, Steps 1–9, Example, Anti-patterns, Limitations, References) and a flat one-level reference list — no nested reference chains and no bundle files needed.

Lists multiple concrete actions: produces not_affected/affected/fixed/under_investigation statements with justification codes via vexctl create, attaches VEX assertions to container images, and outputs .openvex.json files — matching the score-3 anchor for multiple specific concrete actions.

Explicitly answers both what (authors/validates OpenVEX docs, attaches, outputs) and when via a concrete 'Use when a scanner flags a CVE…' trigger clause.

Uses natural trigger terms a user would say ('scanner flags a CVE', 'not exploitable', 'false positives', 'not_affected assertion', 'VEX') with good coverage, beyond just 'some relevant keywords'.

Occupies a clear niche (OpenVEX/vexctl VEX assertions for CVE false-positive suppression) with distinct triggers unlikely to overlap with other skills.
