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 postinstall hook performs first-party AI agent skill setup in the user's Codex skills directory, which warrants a warning under the agent integration policy. Inspected OAuth and bootstrap code use the authentication flow and service endpoint as expected; no concrete attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-12T03:12:48.165Z - **Finished:** 2026-10-12T03:13:23.267Z - **Download time:** 756 ms - **Static scan time:** 148 ms - **AI review time:** 34196 ms - **Total time:** 35102 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:** Installation can place this package's bundled AI agent skill in the user's Codex skills directory. This is first-party agent extension setup, but the package does not require a separate prompt before attempting it. - **Trigger:** npm installation, unless VVICAT\_SKIP\_SKILL\_INSTALL=1 or INIT\_CWD identifies the package itself. - **Impact:** The agent may load instructions for operating the vendor's remote CLI. The inspected source does not establish credential theft or another active attack. - **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:** 2026-10-12T03:13:23.267Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook imports the skill manager, which copies bundled skill files to ~/.codex/skills by default; an environment variable can redirect the destination. - **Rationale:** The postinstall hook performs first-party AI agent skill setup in the user's Codex skills directory, which warrants a warning under the agent integration policy. Inspected OAuth and bootstrap code use the authentication flow and service endpoint as expected; no concrete attack behavior was established. - **Files touched:** ~/.codex/skills/using-vvicat-ai-short-studio-cli - **Network endpoints:** https://ai-short-studio.vvicat.dev, 127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs scripts/postinstall.mjs during installation., The postinstall skips only on an explicit environment flag or when INIT\_CWD resolves to the package itself; otherwise it installs bundled skills., The default install target is the user's ~/.codex/skills directory, and installation copies bundled skill content there., The installed first-party skill guides an AI agent to operate the vendor's remote CLI; this is an agent extension setup capability., Google login uses an OAuth authorization flow and a loopback callback; preflight requests the configured service's bootstrap endpoint. - **Evidence against:** Skill installation skips an existing unmanaged or modified destination unless managed state permits updating; the documented command also requires explicit invocation., The inspected OAuth flow returns the session from the auth client's code exchange, and preflight uses the selected service base URL., No evidence inspected of credential exfiltration, destructive behavior, or remote payload execution. ## Affected versions and remediation This report applies to @aswless\_854771076/ai\_short\_studio\_cli@0.1.61. - Review the evidence and your use of @aswless\_854771076/ai\_short\_studio\_cli@0.1.61 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.
