Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The automatic postinstall installation of package-owned content into the user’s Codex skills directory is a guarded first-party agent extension lifecycle risk. The inspected OAuth code follows explicit login flows and did not establish unrelated credential disclosure. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-12T03:18:27.190Z - **Finished:** 2026-10-12T03:19:02.907Z - **Download time:** 515 ms - **Static scan time:** 179 ms - **AI review time:** 35021 ms - **Total time:** 35717 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The postinstall hook installs bundled VVICAT skills into the user’s Codex skills directory by default. This creates an agent extension during package installation without a separate prompt. - **Trigger:** npm installation, unless the skip environment variable is set or the package is installed from its own directory. - **Impact:** The skill becomes available to the user’s agent and may guide future agent tasks through package-specific instructions. - **Evidence paths:** scripts/postinstall.mjs, dist/skill/skill-manager.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T03:19:02.907Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies package-bundled skill files into the configured skills root, defaulting to ~/.codex/skills. - **Rationale:** The automatic postinstall installation of package-owned content into the user’s Codex skills directory is a guarded first-party agent extension lifecycle risk. The inspected OAuth code follows explicit login flows and did not establish unrelated credential disclosure. - **Files touched:** scripts/postinstall.mjs, dist/skill/skill-manager.js, skills/using-vvicat-ai-short-studio-cli/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs scripts/postinstall.mjs on install; that hook auto-installs bundled skills unless skipped or installed from the package’s own directory., dist/skill/skill-manager.js copies bundled skill files into the configured skills root; the default target is the user’s Codex skills directory., The installed skill is the package’s own VVICAT CLI guide, and it tells agents to check status and ask before updating a non-current skill., Google OAuth uses the Supabase client flow and returns its session to the caller., MemHub login is user-invoked and sends its authorization code and PKCE verifier to the configured service base URL. - **Evidence against:** No inspected source showed credential forwarding to an unrelated recipient, reviewer-directed manipulation, or a remote payload channel., The agent-facing content is bundled with the package and describes its CLI; install safeguards skip unowned or modified skills unless forced. ## Affected versions and remediation This report applies to @aswless\_854771076/ai\_short\_studio\_cli@0.1.94. - Review the evidence and your use of @aswless\_854771076/ai\_short\_studio\_cli@0.1.94 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
