During Pi agent events, it can invoke the Agency CLI and add validated workbase instructions and skill paths. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-22T18:42:40.897Z - **Finished:** 2026-08-22T18:43:50.530Z - **Download time:** 504 ms - **Static scan time:** 2081 ms - **AI review time:** 67045 ms - **Total time:** 69633 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall installs a persistent Agency-owned Pi extension under the user's Pi directory. During Pi agent events, it can invoke the Agency CLI and add validated workbase instructions and skill paths. - **Trigger:** npm postinstall, then Pi agent resource discovery or startup in an Agency workbase - **Impact:** Modifies the Pi agent extension surface and influences Pi sessions in matching workbases; no credential exfiltration or remote payload execution was confirmed. - **Evidence paths:** package.json, scripts/install-pi-extension.ts, pi-extensions/agency.ts, src/utils/interactive-loader.ts, src/services/ReviewService.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-22T18:43:50.530Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Pi extension installation and guarded system-prompt/skill-path augmentation - **Rationale:** The postinstall hook persistently modifies an AI-agent extension surface, which warrants a warning under policy. The extension is package-owned and context-validated, and no concrete malicious behavior was found. - **Files touched:** scripts/install-pi-extension.ts, pi-extensions/agency.ts, $HOME/.pi/agent/extensions/agency.ts, \/.agency/AGENTS.md, \/.claude/skills, \/.agents/skills, \/.opencode/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for:** postinstall automatically runs the Pi-extension installer., Installer copies the package extension into the user's Pi agent extensions directory., Installed extension reads workbase instructions and appends them to Pi's system prompt., Extension activation is guarded by a discovered workbase and validated Agency context. - **Evidence against:** No HTTP client, credential harvesting, obfuscation, or payload-download code found in inspected package sources., The dynamic import resolves a fixed UI preload module, not user-controlled code., Review git fetches and filesystem mutations are CLI/workbase operations, not install-time behavior. ## 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.

Low: Non Install Lifecycle Scripts - **Category:** Manifest - **Confidence:** 80.0% Package declares lifecycle scripts that are not normally run for registry tarball installs. ### 4. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 5. Medium: Dynamic Require - **Category:** Source - **Confidence:** 75.0% - **Path:** src/utils/interactive-loader.ts - **Public source:** [View source]() Package source references dynamic require/import behavior.

Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 11. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 90.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 12. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** src/services/ReviewService.ts - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.
