It installs package-owned prompt skills and can update only directories marked as managed by this package; no source-confirmed credential exfiltration or remote code execution was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-07T06:04:02.914Z - **Finished:** 2026-08-07T06:05:00.472Z - **Download time:** 752 ms - **Static scan time:** 126 ms - **AI review time:** 56679 ms - **Total time:** 57558 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall mutates Codex's shared skill directory without an explicit user command. It installs package-owned prompt skills and can update only directories marked as managed by this package; no source-confirmed credential exfiltration or remote code execution was found. - **Trigger:** npm install outside the package directory - **Impact:** Adds persistent AI-agent instructions; the bundled instructions request CLI preflight, which defaults to a global package update when later followed. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/skill/skill-manager.js, skills/using-vvicat-ai-short-studio-cli/SKILL.md, dist/preflight.js - **Review source:** ai\_review - **Reviewed:** 2026-08-07T06:05:00.472Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic bundled skill installation into ~/.codex/skills - **Rationale:** Source confirms an unconsented postinstall Codex skill installation, but not a concrete malicious chain such as exfiltration, destructive behavior, or remote payload execution. This is a first-party agent-extension lifecycle risk requiring a warning, not a publish block. - **Files touched:** scripts/postinstall.mjs, dist/skill/skill-manager.js, ~/.codex/skills/using-vvicat-ai-short-studio-cli, ~/.codex/skills/short-drama - **Network endpoints:** https://ai-short-studio.vvicat.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json defines postinstall., scripts/postinstall.mjs automatically installs two bundled skills., dist/skill/skill-manager.js targets ~/.codex/skills by default., The installer replaces package-managed skill directories during install., Bundled skill directs preflight, whose default action globally updates this package. - **Evidence against:** Postinstall copies only package-bundled local skill files., Existing unmanaged or modified skills are skipped., No postinstall network, credential harvesting, shell execution, or remote payload loading found., OAuth callback is localhost-only and refresh tokens use the OS keyring. ## Public findings ### 1.
