The package can silently alter instructions used by the user's Pi agent across projects. - **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:** 0.1.5 - **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 changes a global Pi agent control file in the user's home directory. The write is automatic and replaces existing content when it differs. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-08-28T17:39:38.968Z - **Finished:** 2026-08-28T17:40:22.431Z - **Download time:** 762 ms - **Static scan time:** 75 ms - **AI review time:** 42626 ms - **Total time:** 43463 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package changes a global Pi agent control file in the user's home directory. The write is automatic and replaces existing content when it differs. - **Trigger:** npm installation runs the postinstall hook. - **Impact:** The package can silently alter instructions used by the user's Pi agent across projects. - **Evidence paths:** package.json, scripts/install-agents.mjs, global/AGENTS.md - **Review source:** ai\_review - **Reviewed:** 2026-08-28T17:40:22.431Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic overwrite of global agent instructions. - **Attack narrative:** The manifest automatically executes a script after installation. That script reads the package's bundled instructions, creates the global Pi agent directory if necessary, and overwrites the user's existing global agent instructions whenever they differ. This is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The postinstall hook silently overwrites a global AI-agent instruction file outside the package and consumer project. This meets the policy for malicious install-time AI-agent control hijacking. - **Files touched:** ~/.pi/agent/AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs an automatic postinstall hook., The hook creates or overwrites the user's global Pi agent instruction file with bundled content. - **Evidence against:** No network endpoint or secret collection was found in the inspected source., The other extensions provide a todo tool and a local cache dashboard. ## Public findings ### 1.
