A dependency install changes a broad AI-agent control surface without an explicit setup command. - **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:** 3.5.0 - **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 writes an extension into the user-wide Pi agent extension directory. That extension changes Pi agent prompts and exposes skills from multiple agent-tool directories. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T20:11:31.322Z - **Finished:** 2026-09-11T20:12:21.988Z - **Download time:** 773 ms - **Static scan time:** 1665 ms - **AI review time:** 48225 ms - **Total time:** 50666 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:** Installing the package automatically writes an extension into the user-wide Pi agent extension directory. That extension changes Pi agent prompts and exposes skills from multiple agent-tool directories. - **Trigger:** npm installation runs postinstall. - **Impact:** A dependency install changes a broad AI-agent control surface without an explicit setup command. - **Evidence paths:** package.json, scripts/install-pi-extension.ts, pi-extensions/agency.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-11T20:12:21.988Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic user-wide Pi extension installation and system-prompt modification. - **Attack narrative:** The postinstall lifecycle hook invokes an installer that copies the bundled Pi extension into the user's global Pi extensions directory. When Pi starts, that extension augments its system prompt and discovers skills under Claude, Agents, OpenCode, and Pi directories. This is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The package performs a concrete, automatic postinstall write to a user-wide agent extension location and the installed code modifies agent control inputs. This meets the install-control-surface blocking policy despite no observed exfiltration. - **Files touched:** scripts/install-pi-extension.ts, pi-extensions/agency.ts, ~/.pi/agent/extensions/agency.ts ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The automatic postinstall hook installs a Pi agent extension., The installer copies package code into the user-wide Pi agent extensions directory., The installed extension injects instructions into Pi's system prompt and discovers skills from several agent-tool directories. - **Evidence against:** No credential harvesting or network exfiltration was found in the inspected lifecycle installer or extension., The package has no runtime dependency on another release of itself. ## Affected versions and remediation This report applies to @markjaquith/agency@3.5.0. - Avoid installing @markjaquith/agency@3.5.0. 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.
