Installing the package writes a persistent Pi agent extension outside the package. On later Pi agent starts in a validated Agency workbase, that extension reads workbase instructions and modifies the agent system prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 95.0% - **Started:** 2026-09-03T23:21:45.517Z - **Finished:** 2026-09-03T23:22:36.912Z - **Download time:** 503 ms - **Static scan time:** 2479 ms - **AI review time:** 48409 ms - **Total time:** 51395 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package writes a persistent Pi agent extension outside the package. On later Pi agent starts in a validated Agency workbase, that extension reads workbase instructions and modifies the agent system prompt. - **Trigger:** npm postinstall, followed by a Pi agent start in an Agency workbase. - **Impact:** It changes an AI-agent control surface without an explicit setup command; source inspection found no exfiltration or remote payload execution. - **Evidence paths:** package.json, scripts/install-pi-extension.ts, pi-extensions/agency.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-03T23:22:36.912Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global agent-extension installation and startup prompt augmentation. - **Rationale:** This is an automatic first-party agent-extension setup that modifies a global AI-agent control surface, so it warrants a warning. The inspected implementation does not establish malicious behavior or the broader mutation chain required for blocking. - **Files touched:** scripts/install-pi-extension.ts, pi-extensions/agency.ts, .pi/agent/extensions/agency.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Postinstall automatically launches the Pi extension installer., The installer copies a package-controlled file into the user's Pi agent extension directory., The installed extension hooks agent startup and appends Agency-controlled text to the system prompt. - **Evidence against:** The extension only activates after finding an Agency workbase and successful context validation., No runtime outbound network or credential-exfiltration code was found in the inspected lifecycle installer and extension., The manifest has no dependency on another release of this package. ## 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: 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: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** fixtures/protocol/error.json - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```json stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 6 ``` ### 13. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** src/cli.test.ts - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.
