Installation changes the instructions available to Claude and agents using the shared skill convention, including triggers for ordinary review requests. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.14.4 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. The npm postinstall hook adds instructions to foreign, global AI-agent control surfaces without consent. These instructions influence later agent behavior across rig workspaces. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-06T10:09:53.916Z - **Finished:** 2026-10-06T10:10:52.576Z - **Download time:** 1040 ms - **Static scan time:** 802 ms - **AI review time:** 56817 ms - **Total time:** 58660 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 npm postinstall hook adds instructions to foreign, global AI-agent control surfaces without consent. These instructions influence later agent behavior across rig workspaces. - **Trigger:** Installing the package when an existing harness directory is present and RIG\_SKIP\_SKILL\_INSTALL is not 1. - **Impact:** Installation changes the instructions available to Claude and agents using the shared skill convention, including triggers for ordinary review requests. - **Evidence paths:** package.json, bin/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-06T10:10:52.576Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook selects the user's home, creates the rig skill directory under each supported harness, and writes embedded agent instructions. - **Attack narrative:** An npm installation automatically runs the postinstall hook. Unless explicitly disabled, it writes a global rig skill into existing Claude and shared agent directories. The embedded instructions extend activation to review and discussion requests that do not mention rig. Collision checks reduce accidental overwrites but do not provide consent for modifying these foreign agent control surfaces. - **Rationale:** Source proves unconsented postinstall mutation of foreign global AI-agent instruction surfaces, meeting the blocking policy. Package-specific naming, collision checks, and an opt-out do not remove the automatic control-surface mutation. - **Files touched:** ~/.claude/skills/rig/SKILL.md, ~/.agents/skills/rig/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs bin/postinstall.mjs after installation., The hook defaults to the user's home and installs instructions into global Claude and shared agent skill directories., The hook creates skill directories and writes SKILL.md without a consent prompt; installation is enabled unless explicitly disabled., The installed instructions activate on general review and discussion requests within rig workspaces, even without mentioning rig., Existing unrelated skills are preserved, but this guard does not authorize adding global agent instructions. - **Evidence against:** Writes are limited to the rig skill and skipped when the harness directory does not exist., The hook supports an environment opt-out and avoids overwriting recognizable unrelated skills. ## Affected versions and remediation This report applies to @rigxyz/cli@0.14.4. - Avoid installing @rigxyz/cli@0.14.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
