This is an unconsented persistent change to a foreign agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-07-29T18:38:19.085Z - **Finished:** 2026-07-29T18:39:11.542Z - **Download time:** 1278 ms - **Static scan time:** 4057 ms - **AI review time:** 47121 ms - **Total time:** 52457 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall mutates a third-party AI coding-agent package already installed in the dependency tree. This is an unconsented persistent change to a foreign agent control surface. - **Trigger:** npm installation of @crouton-kit/crouter@0.3.154 outside CI - **Impact:** Alters the behavior of another AI-agent package for subsequent use. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/patch-pi-tree-root-ordering.mjs, scripts/install-runtime.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-29T18:39:11.542Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall source rewrite of @earendil-works/pi-coding-agent - **Attack narrative:** Installation runs a postinstall hook that locates a parent-installed @earendil-works/pi-coding-agent package and atomically rewrites its compiled tree-selector source. The mutation happens before the CI skip and survives as a node\_modules modification, changing a foreign AI-agent package without an explicit user command. - **Rationale:** The lifecycle hook concretely mutates a foreign AI-agent implementation during installation. Its narrow, version-checked patch does not remove the unconsented cross-package control-surface write. - **Files touched:** scripts/postinstall.mjs, scripts/patch-pi-tree-root-ordering.mjs, node\_modules/@earendil-works/pi-coding-agent/dist/modes/interactive/components/tree-selector.js, ~/.crouter/runtime ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., scripts/postinstall.mjs invokes the patch before its CI guard., scripts/patch-pi-tree-root-ordering.mjs searches upward for @earendil-works/pi-coding-agent., It rewrites that foreign agent's dist/modes/interactive/components/tree-selector.js., The rewrite changes root ordering and persists in node\_modules. - **Evidence against:** Patch is version-pinned and narrowly replaces one declared source statement., No install-time credential harvesting or non-registry network endpoint was found. ## Public findings ### 1.
