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. A bundled Pi extension imports Claude command and skill files, creates Pi prompt shims, and can execute embedded shell blocks when a matching slash command is invoked. No confirmed credential or data exfiltration was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-26T16:37:19.263Z - **Finished:** 2026-09-26T16:40:55.867Z - **Download time:** 1546 ms - **Static scan time:** 4509 ms - **AI review time:** 210548 ms - **Total time:** 216604 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:** A bundled Pi extension imports Claude command and skill files, creates Pi prompt shims, and can execute embedded shell blocks when a matching slash command is invoked. No confirmed credential or data exfiltration was identified. - **Trigger:** The Pi extension must load, discover resources, and receive a matching slash command. - **Impact:** A selected Claude command can execute its embedded local shell content through the agent integration. This is a guarded agent-extension capability, not a confirmed install-time attack. - **Evidence paths:** dist/builtin-pi-packages/pi-crtr-extensions/extensions/claude-plugin-commands.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-26T16:40:55.867Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The extension indexes files under the user's Claude configuration, writes copied prompt shims under the Pi agent directory, then reads the original selected command and expands its shell blocks. - **Rationale:** The package contains a concrete, guarded agent-extension capability that writes Pi shims and runs shell blocks from indexed Claude command content. Its user-command trigger and lack of confirmed exfiltration support a warning rather than a block. - **Files touched:** 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 has an automatic postinstall hook that stages its runtime., The bundled agent extension reads command and skill sources from the user's Claude configuration., On agent resource discovery, the extension deletes and recreates its Pi shim directory., A matching slash command reads the indexed source and expands embedded shell blocks before transforming input., The observed shell capability is tied to a loaded extension and a matching user slash command; no direct credential export or unrelated network recipient was found in the inspected paths. - **Evidence against:** No evidence in the inspected paths showed secret collection, exfiltration, or a package-controlled network endpoint., The extension's shell expansion is conditional on a user invoking an indexed command rather than an install-time shell execution. ## Affected versions and remediation This report applies to @north-light/crouter@0.3.331. - Review the evidence and your use of @north-light/crouter@0.3.331 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.
