In an Agency workbase, that extension discovers skills and augments Pi system prompts. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-21T07:21:44.116Z - **Finished:** 2026-08-21T07:22:49.144Z - **Download time:** 758 ms - **Static scan time:** 2312 ms - **AI review time:** 61955 ms - **Total time:** 65028 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall installs a globally loaded Pi agent extension. In an Agency workbase, that extension discovers skills and augments Pi system prompts. - **Trigger:** Package installation, followed by a Pi agent start inside an Agency workbase. - **Impact:** Changes an AI-agent control surface without an explicit setup command, but behavior is limited to the package's own workbase context. - **Evidence paths:** package.json, scripts/install-pi-extension.ts, pi-extensions/agency.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-21T07:22:49.144Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** global Pi extension installation and guarded prompt/resource injection - **Rationale:** This is a concrete install-time mutation of a global agent extension surface, so it warrants a warning. The source shows a first-party, context-guarded extension rather than a malicious exfiltration or remote-execution chain. - **Files touched:** pi-extensions/agency.ts, ~/.pi/agent/extensions/agency.ts, .agency/AGENTS.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall invokes the Pi extension installer., Installer copies package code into the global Pi extensions directory., Installed extension registers agent lifecycle hooks and appends workbase instructions to Pi system prompts. - **Evidence against:** The installed payload is a local, packaged TypeScript file; no remote payload retrieval is present., Extension returns without action outside an Agency workbase., No credential harvesting or fixed exfiltration endpoint was found in inspected source. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
