Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.3.67 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. Source inspection does not support the scanner's malicious verdict. The cross-host configuration writes are user-triggered and guarded, but warrant a warning under the firewall policy for explicit AI-agent control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-07-27T12:41:29.554Z - **Finished:** 2026-07-27T12:42:18.932Z - **Download time:** 1013 ms - **Static scan time:** 3584 ms - **AI review time:** 44780 ms - **Total time:** 49378 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:** No concrete malicious chain was found. The CLI does provision marker-guarded command templates into existing Claude/pi host directories when users run crtr. - **Trigger:** User runs a crtr CLI command. - **Impact:** Adds or updates package-owned command templates in existing host configuration directories. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli.js, dist/core/host-exports/export.js, dist/core/host-exports/builtins.js, dist/core/self-update.js - **Review source:** ai\_review - **Reviewed:** 2026-07-27T12:42:18.932Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Marker-guarded AI-agent command-template export - **Rationale:** Source inspection does not support the scanner's malicious verdict. The cross-host configuration writes are user-triggered and guarded, but warrant a warning under the firewall policy for explicit AI-agent control-surface mutation. - **Files touched:** dist/cli.js, dist/core/host-exports/export.js, dist/core/host-exports/builtins.js, scripts/postinstall.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** dist/cli.js invokes host export provisioning on CLI runs., dist/core/host-exports/export.js writes marker-owned templates to existing ~/.claude and ~/.pi agent command directories., scripts/postinstall.mjs patches a version-pinned dependency file during install. - **Evidence against:** Postinstall only alters one exact pi UI ordering expression; no network or credential access., Host exports require an explicit CLI invocation, existing host roots, and do not overwrite markerless user files., Runtime self-update and plugin installation are exposed through user-invoked commands., No source evidence of stealth exfiltration, remote payload execution, or destructive foreign-agent takeover. ## Affected versions and remediation This report applies to @crouton-kit/crouter@0.3.67. - Review the evidence and your use of @crouton-kit/crouter@0.3.67 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.
