Mutates broad AI-agent control surfaces without an explicit user command, allowing the package's skill instructions to influence installed agents. - **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:** 0.7.0 - **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. Installing the package automatically installs its bundled AI-agent skill into global agent skill locations. The target rules cover 75 global targets across 77 agent integrations. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-06T04:29:28.430Z - **Finished:** 2026-09-06T04:30:22.596Z - **Download time:** 506 ms - **Static scan time:** 405 ms - **AI review time:** 53254 ms - **Total time:** 54166 ms The recorded confidence comes from the underlying analysis.

The target rules cover 75 global targets across 77 agent integrations. - **Trigger:** npm postinstall during package installation - **Impact:** Mutates broad AI-agent control surfaces without an explicit user command, allowing the package's skill instructions to influence installed agents. - **Evidence paths:** package.json, npm/scripts/postinstall.mjs, npm/lib/skill-install.mjs, npm/generated/skills-rules.json - **Review source:** ai\_review - **Reviewed:** 2026-09-06T04:30:22.596Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Non-interactive global installation of a bundled agent skill - **Attack narrative:** When npm installs this package, its postinstall hook calls the skill installer. That installer loads rules for 77 agents and invokes the skills CLI with --global and --yes to add the bundled pi-worker skill. This performs an unconsented install-time mutation of broad AI-agent skill locations, including the universal home skill directory and detected third-party agent targets. - **Rationale:** The automatic lifecycle hook installs a bundled skill globally across a broad set of foreign AI-agent integrations without explicit user action. This is concrete install-hook abuse of an AI-agent control surface. - **Files touched:** skills/pi-worker/, npm/generated/skills-rules.json, $HOME/.agents/skills/pi-worker ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall lifecycle hook automatically., Postinstall invokes the bundled skill installer., The installer targets 77 agent integrations, including 75 global targets., The installer launches a skills CLI with global, non-interactive add flags to install its bundled skill. - **Evidence against:** The shown JavaScript uses bounded child-process handling and disables shell execution., No network endpoint, credential collection, or runtime self-dependency was found in the inspected source. ## Affected versions and remediation This report applies to pi-worker@0.7.0. - Avoid installing pi-worker@0.7.0. 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.
