A package can establish instructions consumed by AI coding agents across the project and retain them after its cleanup path. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 4.2.5 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm install, lifecycle code can place package-supplied AGENTS.md and AGENTS/ at the consuming project's root. Those files are preserved by the next preinstall cleanup; a build helper also downloads remote replacement plugin code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-15T20:37:08.424Z - **Finished:** 2026-08-15T20:38:17.639Z - **Download time:** 508 ms - **Static scan time:** 355 ms - **AI review time:** 68351 ms - **Total time:** 69215 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm install, lifecycle code can place package-supplied AGENTS.md and AGENTS/ at the consuming project's root. Those files are preserved by the next preinstall cleanup; a build helper also downloads remote replacement plugin code. - **Trigger:** npm install with codeplayCommon.agentsVersion set to 1.0; later project build execution - **Impact:** A package can establish instructions consumed by AI coding agents across the project and retain them after its cleanup path. - **Evidence paths:** package.json, scripts/sync-files.js, scripts/uninstall.js, agent-templates/manifest.json, files/buildCodeplay/codeplayBeforeBuild-6.2.js - **Review source:** ai\_review - **Reviewed:** 2026-08-15T20:38:17.639Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time project-root agent instruction injection with persistent remote-update helper - **Attack narrative:** The package’s postinstall script reads a package-selected agent-template version and copies AGENTS.md plus AGENTS/ into the consuming project root without an interactive consent step. These are broad agent instruction files rather than package-owned configuration, and its preinstall cleanup intentionally excludes them, leaving the control surface in place. The bundled build helper separately obtains replacement code from the vendor endpoint without integrity verification. The shipped default agent version is missing, but the documented 1.0 selection activates the injection path. - **Rationale:** This is an unconsented install-time mutation of a broad AI-agent control surface, which meets the firewall block boundary. The absent default template limits default activation but does not remove the concrete version-1.0 lifecycle path. - **Files touched:** AGENTS.md, AGENTS/, files/, buildCodeplay/, package.json - **Network endpoints:** https://htmlcodeplay.com/code-play-plugin/versions.json, https://htmlcodeplay.com/code-play-plugin/ ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm preinstall and postinstall run automatically., Postinstall selects an agent template from project configuration or its manifest., Selected template is copied as root AGENTS.md and AGENTS/., Preinstall explicitly preserves these agent-control files., Build helper downloads replacement code from htmlcodeplay.com without integrity verification. - **Evidence against:** Agent templates contain project-development guidance, not credential theft., No install-time network or exfiltration code was found., Default manifest selects absent v1.1, causing agent-copy setup to fail unless 1.0 is explicitly selected. ## Public findings ### 1.
