This changes Claude, generic agents, and Codex behavior without an explicit setup command. - **Trigger:** npm installation, including transitive installation when lifecycle scripts run - **Impact:** Persistent unconsented AI-agent control-surface mutation - **Evidence paths:** package.json, scripts/install-skill.mjs, skills/scriptctl/SKILL.md, dist/infra/llm/gemini-video-model.js, dist/infra/script-output-api.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T12:41:34.179Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies bundled agent instructions into foreign user skill directories - **Attack narrative:** Installing the package invokes scripts/install-skill.mjs automatically. It deletes and replaces ~/.claude/skills/scriptctl, ~/.agents/skills/scriptctl, and ~/.codex/skills/scriptctl with a bundled SKILL.md, thereby persistently injecting package-authored operating instructions into multiple agent platforms without an explicit user setup action. - **Rationale:** The install hook performs unconsented mutation of broad, foreign AI-agent skill control surfaces. This meets the blocking policy even though the inspected installer shows no separate exfiltration chain. - **Files touched:** scripts/install-skill.mjs, skills/scriptctl/SKILL.md, ~/.claude/skills/scriptctl, ~/.agents/skills/scriptctl, ~/.codex/skills/scriptctl ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/install-skill.mjs as postinstall., scripts/install-skill.mjs targets ~/.claude/skills, ~/.agents/skills, and ~/.codex/skills., Postinstall force-removes each target scriptctl directory, then copies its bundled skill., Bundled skills/scriptctl/SKILL.md provides agent instructions and CLI workflows. - **Evidence against:** Installer has an environment-variable opt-out., Installer only writes its named scriptctl subdirectory and shows no network or credential exfiltration., Runtime LLM/API networking is tied to user-invoked CLI workflows and configured endpoints. ## Public findings ### 1.
