resolve-docker-vulnerabilities — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited resolve-docker-vulnerabilities (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

This skill guides you through the process of listing images, checking for vulnerabilities, planning remediation, and verifying the fixes by publishing to a staging repository.
Run the build on fir-tools-builds and publish to the staging repository in firebase-cli to see the baseline vulnerabilities after the build's own updates.
./scripts/publish/firebase-docker-image/run.sh --build-project fir-tools-builds --repo staging --target firebase-cliCheck the vulnerability reports for the image just pushed to staging. You will need to find the digest of the image first.
gcloud artifacts docker images list us-docker.pkg.dev/firebase-cli/staging/firebaseThen check vulnerabilities using the digest:
gcloud artifacts vulnerabilities list us-docker.pkg.dev/firebase-cli/staging/firebase@sha256:<DIGEST>To investigate which layers and file paths are causing the vulnerabilities, run the command with --format=json:
gcloud artifacts vulnerabilities list us-docker.pkg.dev/firebase-cli/staging/firebase@sha256:<DIGEST> --format=jsonLook for fileLocation and layerDetails in the output to understand if the vulnerability is in:
/usr/local/node_packages/node_modules). Recommend updating the package.json and running the build again. You can use overrides as needed here to upgrade transitive dependencies to non-breaking versions./usr/local/lib/node_modules/npm). Recommend waiting for upstream fixes (which will be pulled in as soon as they are available)./root/.cache/firebase/emulators). Recommend raising these issues to the team owning the emulator.For each vulnerable package identified:
Present the proposed plan to the user for approval before making changes.
After making changes to the Dockerfile or related files, repeat Step 1 and Step 2 to publish a new staged image and verify that the vulnerabilities have been resolved.
