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 automatic postinstall installs a first-party agent extension, which is a guarded agent-extension lifecycle risk under the review policy. The source shows ownership checks for existing files and no concrete malicious behavior in the inspected paths. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T20:05:29.558Z - **Finished:** 2026-10-10T20:06:19.993Z - **Download time:** 3593 ms - **Static scan time:** 13105 ms - **AI review time:** 33734 ms - **Total time:** 50435 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 installs a package-owned extension into the user’s Pi agent extensions directory. This is a guarded first-party agent extension setup and no broader confirmed attack surface was identified. - **Trigger:** Installing the package through npm runs its postinstall hook. - **Impact:** The extension becomes available to the user’s Pi agent. No credential access or exfiltration was established from the inspected evidence. - **Evidence paths:** package.json, scripts/install-pi-extension.ts - **Review source:** ai\_review - **Reviewed:** 2026-10-10T20:06:19.993Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook copies the bundled extension into the user’s Pi agent extensions directory; existing files are protected unless ownership can be verified. - **Rationale:** The automatic postinstall installs a first-party agent extension, which is a guarded agent-extension lifecycle risk under the review policy. The source shows ownership checks for existing files and no concrete malicious behavior in the inspected paths. - **Files touched:** package.json, scripts/install-pi-extension.ts, ~/.pi/agent/extensions/agency.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook automatically runs the extension installer., The installer targets the user’s Pi agent extensions directory., Installation creates the destination directory and copies the bundled extension when no file exists there., Uninstall removes the extension only when its ownership hash matches., Integration inspection also targets project-level agent and OpenCode configuration paths. - **Evidence against:** The installer skips an existing destination it cannot verify as package-managed., No evidence inspected here shows credential collection, exfiltration, or a broader agent-control write. ## Affected versions and remediation This report applies to @markjaquith/agency@3.19.0. - Review the evidence and your use of @markjaquith/agency@3.19.0 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.
