+## Plugin scanner
+
+`.github/workflows/plugin-scanner.yml` runs the [HOL AI Plugin
+Scanner](https://github.com/hashgraph-online/hol-guard) on every pull request
+and every push to `main`, and fails the build on a score below 80 or on any
+high or critical finding. The gate is not only ours: the
+[awesome-ai-plugins](https://github.com/hashgraph-online/awesome-ai-plugins)
+catalog lists a repository only if that repository runs this scan itself, and
+then re-scans a fresh clone of it against the same two thresholds.
+
+Run what CI runs:
+
+```bash
+pipx run plugin-scanner scan . --min-score 80 --fail-on-severity high
+```
+
+`.plugin-scanner.toml` in the repository root is discovered automatically — by
+your local run and by the catalog's re-scan alike. It suppresses
+`HARDCODED_SECRET` and `SHELL_INJECTION_PATTERN` under the test directories and
+nowhere else. The credentials there are fake on purpose, because the assertion
+is that NeatContext keeps material like that out of a saved context, and the
+host tests start bridges with `spawn(process.execPath, [script, ...args])` —
+the structured-argument form the rule's own remediation asks for.
+
+Both rules stay live on every line of shipped host code, so a real finding in
+`shared/core/` or in a host's `src/` still fails the build. Widen the ignore
+list only when a finding is genuinely about the test rather than about the
+code, and say which in the pull request.

 ## Releases
 
 There are two release streams, because the hosts are distributed differently.
