A package install changes a separate AI-agent control surface without an explicit user command. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 3.2.12 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically adds a global Pi agent extension. That extension changes agent resources and system prompts for matching workbases. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-05T04:08:18.377Z - **Finished:** 2026-09-05T04:09:02.861Z - **Download time:** 515 ms - **Static scan time:** 2365 ms - **AI review time:** 41602 ms - **Total time:** 44484 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically adds a global Pi agent extension. That extension changes agent resources and system prompts for matching workbases. - **Trigger:** npm postinstall - **Impact:** A package install changes a separate AI-agent control surface without an explicit user command. - **Evidence paths:** package.json, scripts/install-pi-extension.ts, pi-extensions/agency.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-05T04:09:02.861Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Global Pi extension installation and agent prompt modification - **Attack narrative:** During npm postinstall, the package copies its extension to the user's global Pi agent extension directory. When Pi later starts in a matching workbase, that extension exposes skill directories and appends workbase instructions to the agent system prompt. This is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The automatic postinstall writes and activates code in Pi's user-wide extension location, then alters agent context and prompts. This meets the install-control-surface block policy despite no observed exfiltration. - **Files touched:** ~/.pi/agent/extensions/agency.ts, pi-extensions/agency.ts ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook automatically runs the Pi extension installer., The installer creates a directory in the user's home folder and copies an extension into Pi's global agent-extension location., The installed extension discovers cross-tool skill directories and appends project instructions to Pi agent system prompts. - **Evidence against:** No lifecycle-time network or credential-exfiltration code was found., The package has no runtime dependency on another release of itself. ## Public findings ### 1.
