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. LPM treats this as warn-only first-party agent extension lifecycle risk. The package automatically installs a runtime and patches a specific Pi dependency during npm post-install. Its bundled agent extension writes Pi command shims and can expand shell blocks from discovered command content. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-09-29T04:19:16.723Z - **Finished:** 2026-09-29T04:20:53.368Z - **Download time:** 1771 ms - **Static scan time:** 9868 ms - **AI review time:** 85005 ms - **Total time:** 96645 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 package automatically installs a runtime and patches a specific Pi dependency during npm post-install. Its bundled agent extension writes Pi command shims and can expand shell blocks from discovered command content. - **Trigger:** Installing the package triggers post-install; using the Pi extension triggers command discovery and input handling. - **Impact:** This is a guarded agent-extension and dependency-mutation capability. No confirmed credential theft, remote code execution chain, or broad agent-control takeover was established. - **Evidence paths:** scripts/postinstall.mjs, scripts/install-runtime.mjs, scripts/patch-pi-tree-root-ordering.mjs, dist/builtin-pi-packages/pi-crtr-extensions/extensions/claude-plugin-commands.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-29T04:20:53.368Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Post-install launches a runtime installer, which runs npm with scripts disabled and patches Pi. The extension rebuilds local shims and processes shell blocks for matched commands. - **Rationale:** The automatic lifecycle hook mutates a specific agent dependency and the bundled extension writes agent command shims with shell-capable command processing. The inspected source does not establish malicious intent or an active attack, so a non-blocking warning is appropriate. - **Files touched:** scripts/postinstall.mjs, scripts/install-runtime.mjs, scripts/patch-pi-tree-root-ordering.mjs, dist/builtin-pi-packages/pi-crtr-extensions/extensions/claude-plugin-commands.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package declares an automatic post-install hook., The post-install hook launches the runtime installer., The installer runs a locked dependency installation with lifecycle scripts disabled, then applies a Pi patch., The patch locates and alters a pinned Pi dependency file., The bundled Pi extension recreates command shims under the user's Pi agent directory., The extension expands shell blocks only through its Pi input handling. - **Evidence against:** The inspected nested dependency installation explicitly disables lifecycle scripts., No credential collection, exfiltration sink, hidden remote payload, or self-dependency was found in the inspected paths. ## Affected versions and remediation This report applies to @north-light/crouter@0.3.369. - Review the evidence and your use of @north-light/crouter@0.3.369 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.
