Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 3.21.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook automatically adds a package-owned extension to the user’s global Pi configuration, creating an agent extension lifecycle risk. The installer limits replacement of existing files, and the inspected extension behavior does not establish a malicious attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-14T09:28:43.490Z - **Finished:** 2026-10-14T09:30:02.070Z - **Download time:** 2061 ms - **Static scan time:** 13641 ms - **AI review time:** 62875 ms - **Total time:** 78580 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The postinstall hook automatically installs the package’s own Pi extension in the user’s global extension directory. The extension adds Agency workbase context to future prompts; the inspected source does not establish a malicious action. - **Trigger:** Installing the package with lifecycle scripts enabled. - **Impact:** Pi sessions can receive Agency workbase instructions and context without a separate extension setup command. This guarded first-party extension setup warrants a warning, but no concrete attack was established. - **Evidence paths:** package.json, scripts/install-pi-extension.ts, pi-extensions/agency.ts, src/services/IntegrationService.ts - **Review source:** ai\_review - **Reviewed:** 2026-10-14T09:30:02.070Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies the package-owned extension into the global Pi extensions directory, then Pi loads it in later sessions. - **Rationale:** The postinstall hook automatically adds a package-owned extension to the user’s global Pi configuration, creating an agent extension lifecycle risk. The installer limits replacement of existing files, and the inspected extension behavior does not establish a malicious attack. - **Files touched:** .pi/agent/extensions/agency.ts, scripts/install-pi-extension.ts, pi-extensions/agency.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs its Pi extension installer from its postinstall hook., The installer targets the user’s global Pi extension directory and copies the package’s extension there during installation., For an existing extension, the installer skips changes unless it can verify the file is package-owned and unchanged., The extension adds Agency workbase context and instructions to later Pi system prompts., IntegrationService inspects workbase-scoped agent configuration; its sync path is a separate service operation. - **Evidence against:** The installer preserves existing extensions it cannot verify as package-owned and unchanged., The inspected extension source establishes no credential transfer or malicious action. ## Affected versions and remediation This report applies to @markjaquith/agency@3.21.0. - Review the evidence and your use of @markjaquith/agency@3.21.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
