A package controls the user's broad AI-agent instruction surface without an explicit setup 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:** 0.1.6 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package silently replaces global instructions for the Pi coding agent. This affects future agent behavior outside the installed project. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-08-28T17:39:39.225Z - **Finished:** 2026-08-28T17:40:21.275Z - **Download time:** 502 ms - **Static scan time:** 80 ms - **AI review time:** 41467 ms - **Total time:** 42050 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package silently replaces global instructions for the Pi coding agent. This affects future agent behavior outside the installed project. - **Trigger:** npm installation invokes the postinstall hook. - **Impact:** A package controls the user's broad AI-agent instruction surface without an explicit setup command. - **Evidence paths:** package.json, scripts/install-agents.mjs, global/AGENTS.md, extensions/cache-export/index.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-28T17:40:21.275Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Writes bundled instructions to the global Pi agent configuration. - **Attack narrative:** The package declares a postinstall hook that reads its bundled instruction file and writes it to the user's global Pi agent configuration. The write is automatic, creates parent directories, and replaces existing content whenever it differs. Although no exfiltration or remote payload was found, this is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The automatic postinstall hook overwrites a global AI-agent instruction file under the user's home directory. This meets the policy boundary for malicious install-time AI-agent control-surface mutation. - **Files touched:** scripts/install-agents.mjs, global/AGENTS.md, ~/.pi/agent/AGENTS.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Installation automatically runs an agent-configuration writer., The hook creates and overwrites the global Pi agent instruction file in the user's home directory. - **Evidence against:** No network endpoint, credential collection, or payload download was found., The extension command only exports a local dashboard when invoked. ## Public findings ### 1.
