This mutates an AI-agent control surface without an explicit user command, but the installed content is bundled rather than remotely fetched. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-12T07:20:39.504Z - **Finished:** 2026-08-12T07:21:26.111Z - **Download time:** 510 ms - **Static scan time:** 161 ms - **AI review time:** 45934 ms - **Total time:** 46607 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall automatically deploys bundled agent skills into the current user's Codex skill directory. This mutates an AI-agent control surface without an explicit user command, but the installed content is bundled rather than remotely fetched. - **Trigger:** npm installation runs postinstall. - **Impact:** Installs or updates package-managed AI-agent skills that can influence future Codex agent behavior. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/skill/skill-manager.js, skills/using-vvicat-ai-short-studio-cli/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-12T07:21:26.111Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic bundled-skill deployment to ~/.codex/skills - **Rationale:** The package has a concrete install-time AI-agent control-surface mutation, warranting a warning. It does not show exfiltration, remote payload delivery, or other evidence supporting a malicious block verdict. - **Files touched:** scripts/postinstall.mjs, dist/skill/skill-manager.js, skills/using-vvicat-ai-short-studio-cli, skills/short-drama, skills/humanizer, ~/.codex/skills/using-vvicat-ai-short-studio-cli, ~/.codex/skills/short-drama, ~/.codex/skills/humanizer ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall directly imports and runs automatic skill installation., Default install target is the user's ~/.codex/skills directory., Installer copies three bundled skills and replaces package-managed targets during npm installation. - **Evidence against:** Installer supports VVICAT\_SKIP\_SKILL\_INSTALL opt-out., It skips non-managed or locally modified skill directories rather than overwriting them., No install-time network, credential collection, or remote payload execution was found. ## Public findings ### 1.
