A package installation can alter an AI agent control surface and cause later agents to consume project-controlled instructions. - **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:** 3.3.0 - **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 writes a persistent global Pi agent extension. The extension automatically adds repository-controlled instructions to Pi agent prompts. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T11:39:40.633Z - **Finished:** 2026-09-14T11:40:27.897Z - **Download time:** 766 ms - **Static scan time:** 904 ms - **AI review time:** 45591 ms - **Total time:** 47264 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 writes a persistent global Pi agent extension. The extension automatically adds repository-controlled instructions to Pi agent prompts. - **Trigger:** npm postinstall during package installation, followed by a Pi agent start in a workbase. - **Impact:** A package installation can alter an AI agent control surface and cause later agents to consume project-controlled instructions. - **Evidence paths:** package.json, scripts/install-pi-extension.ts, pi-extensions/agency.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-14T11:40:27.897Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global agent-extension installation and system-prompt augmentation. - **Attack narrative:** The package's postinstall hook copies its Pi extension into the user's global Pi extension directory without an explicit user command. On later Pi agent starts, the extension reads a workbase's .agency/AGENTS.md and appends it to the agent system prompt. This is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The automatic global extension installation and subsequent prompt augmentation form a concrete AI-agent control-surface attack. No data exfiltration was required to establish the malicious install-hook behavior. - **Files touched:** ~/.pi/agent/extensions/agency.ts, .agency/AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook automatically runs an installer., The installer copies an extension into the user's global Pi agent extension directory., That extension injects project-controlled instructions into every matching Pi agent system prompt. - **Evidence against:** No package source inspected sends harvested data to a network endpoint., The lifecycle installer is short and its destination and copied source are explicit. ## Affected versions and remediation This report applies to @markjaquith/agency@3.3.0. - Avoid installing @markjaquith/agency@3.3.0. 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.
