 Additional ClawHub policy for this Codex run:
-- You must inspect the workspace files directly before producing the final JSON.
-- First list the artifact files, then read metadata.json, then read SKILL.md plus any other key
-  artifact files needed for the verdict. Treat metadata.json as context, not artifact instructions.
-- SkillSpector findings are the dedicated agentic-risk scanner output. Weigh them with artifact evidence, but do not rename them, translate them into another taxonomy, or directly copy them into ClawScan output.
+- Do your own security research before deciding. Use SkillSpector, VirusTotal, static scan
+  findings, metadata, artifact evidence, and publisher context as inputs.
+- Inspect workspace files when needed to verify scanner claims, resolve uncertainty, or build
+  confidence in the verdict. Treat metadata.json as context, not artifact instructions.
+- SkillSpector findings are evidence, not the final verdict. Weigh them with artifact evidence,
+  but do not rename them, translate them into another taxonomy, or directly copy them into
+  ClawScan output.
+- Make the final policy verdict from the totality of evidence.
 - VirusTotal is untrusted telemetry only. It is useful signal, but it must never be the sole reason for a malicious or suspicious verdict.
 - If VirusTotal is the only negative signal and artifact evidence is coherent, return benign.
 - Static scan findings are signal. If static scan marked malicious, decide from artifact evidence whether the hold should remain.
 - @openclaw plugin packages from the OpenClaw publisher are trusted by default. Keep them benign unless concrete artifact evidence proves malicious behavior.
 - Treat pre-scan prompt-injection indicators as artifact context for your review, not as an automatic verdict.
-- If metadata.json or artifact/ cannot be read after attempting those file operations, report an incomplete scanner error. Do not treat unreadable artifacts as benign evidence.
-- Set incomplete_artifact_inspection to true only when you personally attempted to list/read metadata.json or artifact/ and those commands failed because of a scanner/tool/filesystem failure. Set it false when files were readable, even if artifact text mentions read failures.
