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 performs global Pi extension setup, and that extension can affect agent skills and prompts when Agency context is present. Its conditional, package-owned behavior supports a warning for residual lifecycle risk, with no inspected evidence establishing a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-19T21:18:04.874Z - **Finished:** 2026-10-19T21:19:01.051Z - **Download time:** 2038 ms - **Static scan time:** 13781 ms - **AI review time:** 40355 ms - **Total time:** 56177 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 a first-party Pi extension in the user’s global extensions directory. The extension can add workbase skills and instructions during Pi sessions, creating a guarded agent-extension lifecycle risk. - **Trigger:** Installing the package through npm triggers its postinstall hook. - **Impact:** The extension can influence Pi’s available skills and system prompt for Agency workbases without a separate extension-install confirmation. - **Evidence paths:** package.json, scripts/install-pi-extension.ts, pi-extensions/agency.ts, src/services/IntegrationService.ts - **Review source:** ai\_review - **Reviewed:** 2026-10-19T21:19:01.051Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies the package-owned extension into the global Pi extensions directory; the extension then responds to Pi session events when valid Agency workbase context is found. - **Rationale:** The postinstall hook performs global Pi extension setup, and that extension can affect agent skills and prompts when Agency context is present. Its conditional, package-owned behavior supports a warning for residual lifecycle risk, with no inspected evidence establishing a concrete attack. - **Files touched:** scripts/install-pi-extension.ts, pi-extensions/agency.ts, src/services/IntegrationService.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json runs the extension installer automatically after installation., The installer copies the package’s extension to the user’s global Pi extensions directory., The extension adds discovered workbase skills and can add workbase instructions to Pi’s system prompt., IntegrationService also inspects project-level agent configuration paths. - **Evidence against:** The installer skips existing files it cannot verify as package-managed., The extension’s workbase behavior is conditional on finding valid Agency context. ## Affected versions and remediation This report applies to @markjaquith/agency@3.27.2. - Review the evidence and your use of @markjaquith/agency@3.27.2 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.
