testland/vex-author

Authors and validates OpenVEX documents - produces `not_affected`, `affected`, `fixed`, and `under_investigation` statements with justification codes using `vexctl create`; attaches VEX assertions to container images; outputs `.openvex.json` files consumed on a downstream VEX-filter / vulnerability-prioritization path. Use when a scanner flags a CVE that analysis confirms is not exploitable in your deployment, and a machine-readable `not_affected` assertion is needed to suppress false positives without discarding the finding from the audit trail.

Low

W012: Unverifiable external dependency detected (runtime URL that controls agent).

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

The skill invokes "go install github.com/openvex/vexctl@latest" (and references https://github.com/openvex/vexctl), which fetches and installs remote executable code at runtime that the skill relies on to create/merge/attest VEX documents.
