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. An install hook patches a Pi agent dependency and provisions a package runtime. Its bundled extension writes Pi command shims and can run shell blocks from indexed Claude command content after a matching slash command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-28T06:17:20.214Z - **Finished:** 2026-09-28T06:20:44.621Z - **Download time:** 1273 ms - **Static scan time:** 8858 ms - **AI review time:** 194275 ms - **Total time:** 204407 ms The recorded confidence comes from the underlying analysis.

Its bundled extension writes Pi command shims and can run shell blocks from indexed Claude command content after a matching slash command. - **Trigger:** Installing the package runs postinstall; later, a user invokes an indexed Pi slash command. - **Impact:** A guarded first-party agent extension can execute command-provided shell content in the active working directory. No credential export, unrelated network recipient, or destructive payload was confirmed. - **Evidence paths:** scripts/postinstall.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:** 2026-09-28T06:20:44.621Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle script calls the Pi patch and runtime installer. The extension rebuilds its shim directory, reads the indexed command, and expands shell blocks through the Pi shell runner. - **Rationale:** The package automatically modifies an agent dependency and provides an extension that executes shell-enabled command content. The observed user-command gate and absence of a confirmed export or destructive payload support a warning rather than a block. - **Files touched:** scripts/postinstall.mjs, scripts/patch-pi-tree-root-ordering.mjs, scripts/install-runtime.mjs, dist/builtin-pi-packages/pi-crtr-extensions/extensions/claude-plugin-commands.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package defines an automatic postinstall hook., Postinstall invokes runtime installation and patches the bundled Pi dependency., The patch rewrites a specific Pi interactive-agent file., The bundled Pi extension rebuilds a user-agent shim directory and executes shell blocks from selected command content. - **Evidence against:** The runtime dependency installation disables dependency lifecycle scripts., The command extension only acts on slash commands that resolve to its indexed command records. ## Affected versions and remediation This report applies to @north-light/crouter@0.3.367. - Review the evidence and your use of @north-light/crouter@0.3.367 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.
