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:** 4.3.8 - **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. This package establishes a server-controlled AI-agent instruction update path through an install-injected build script. The source documents the behavior and does not show direct credential theft or install-time agent-file writes. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-27T07:39:27.109Z - **Finished:** 2026-08-27T07:41:07.850Z - **Download time:** 254 ms - **Static scan time:** 889 ms - **AI review time:** 99597 ms - **Total time:** 100741 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 build command can download server-controlled AI-agent instruction files into the project root. Installation also rewrites the build command to invoke that behavior. - **Trigger:** npm install modifies the project build script; npm run build activates the download. - **Impact:** A server-controlled AGENTS.md can influence AI agents working in the project. - **Evidence paths:** package.json, scripts/sync-files.js, files/buildCodeplay/codeplayBeforeBuild-6.2.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-27T07:41:07.850Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote agent-instruction archive download and project-root overwrite. - **Rationale:** This package establishes a server-controlled AI-agent instruction update path through an install-injected build script. The source documents the behavior and does not show direct credential theft or install-time agent-file writes. - **Files touched:** package.json, AGENTS.md, AGENTS/, .codeplay-version - **Network endpoints:** https://htmlcodeplay.com/code-play-plugin/versions.json, https://htmlcodeplay.com/code-play-plugin/${zipName} ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Install hooks delete and copy project files, then rewrite the project's npm scripts., The injected build script fetches a server-selected archive and writes AGENTS.md and AGENTS/ at the project root., The remote archive is structurally checked but is not authenticated or integrity-pinned. - **Evidence against:** Agent instruction updates occur during npm run build, not directly during installation., The README clearly documents the agent-file update behavior., No credential harvesting or unrelated data exfiltration was found. ## Affected versions and remediation This report applies to codeplay-common@4.3.8. - Review the evidence and your use of codeplay-common@4.3.8 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.
