README
coder-skill-scanner
Periodic, GitHub-Actions-as-SaaS security scanner for agent skills declared in the [Coder registry](https://github.com/coder/registry) catalogue.
Every 6 hours, the scheduled workflow in this repo:
- Enumerates every skill in
coder/registry(both the in-tree.agents/skills/format and the future external-sources format). - Shallow-clones each source repo.
- Runs NVIDIA SkillSpector over
the upstream content. The scheduled scan runs SkillSpector's LLM
semantic pass when the workflow's LLM credential secret is
configured, and falls back to
--no-llmstatic-only mode otherwise. - Builds a per-skill verdict (
clean,suspicious,malicious,unknown) fromrisk_scoreplus the thresholds inconfig.yaml. - Builds the React SPA in
site/and ships it together withlatest.json,schema.json, and a rolling history of prior snapshots to GitHub Pages. Also publishes a versioned GitHub Release for archival.
The public site is the same React app that registry-server hosts at `registry.coder.com`, scoped down to scan results. Same Vite, Tailwind, Radix, react-router-dom, and tanstack-query stack.
The registry site reads the public report through a small proxy endpoint in `coder/registry-server` (separate PR) and shows a per-skill badge. The registry's deploys are not gated on the scan result.
