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:** 4.3.9 - **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. The package creates a remote, unpinned AI-agent instruction update path during its build workflow. This is a real capability risk, but it is not an unconsented install-time AI control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-27T21:25:11.527Z - **Finished:** 2026-08-27T21:27:02.658Z - **Download time:** 257 ms - **Static scan time:** 695 ms - **AI review time:** 110178 ms - **Total time:** 111131 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 user-run build can replace project-root AI agent instruction files with a remote ZIP chosen by the vendor server. No install-time agent-control write was confirmed. - **Trigger:** The consuming project runs npm run build after installation. - **Impact:** A compromised or changed vendor endpoint could alter instructions read by AI coding agents in the project. - **Evidence paths:** package.json, scripts/sync-files.js, files/buildCodeplay/codeplayBeforeBuild-6.2.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-27T21:27:02.658Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote agent-instruction download and project-root overwrite. - **Rationale:** The package creates a remote, unpinned AI-agent instruction update path during its build workflow. This is a real capability risk, but it is not an unconsented install-time AI control-surface mutation. - **Files touched:** package.json, files/buildCodeplay/codeplayBeforeBuild-6.2.js, AGENTS.md, AGENTS/ - **Network endpoints:** https://htmlcodeplay.com/code-play-plugin/versions.json, https://htmlcodeplay.com/code-play-plugin/agents-\.zip ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Install hooks copy build tooling into the consuming project and replace its build command., A build command fetches a server-selected ZIP and writes AGENTS.md and AGENTS/ at the project root., The downloaded agent instructions are not integrity-pinned or signed., The build entry point invokes the agent-instruction sync. - **Evidence against:** The agent-instruction download is not executed by preinstall or postinstall., The source documents this behavior and limits it to npm run build., No credential harvesting or unrelated data exfiltration was found in the inspected lifecycle and build code. ## Affected versions and remediation This report applies to codeplay-common@4.3.9. - Review the evidence and your use of codeplay-common@4.3.9 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.
