Host AI coding agents can receive package-authored instructions and skills. - **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:** 0.5.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package as a project dependency automatically imports an AI-agent kit into the host repository. It mutates broad, cross-vendor agent instruction and configuration surfaces without an explicit bootstrap command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-03T13:57:05.944Z - **Finished:** 2026-08-03T13:57:51.191Z - **Download time:** 765 ms - **Static scan time:** 298 ms - **AI review time:** 44183 ms - **Total time:** 45247 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package as a project dependency automatically imports an AI-agent kit into the host repository. It mutates broad, cross-vendor agent instruction and configuration surfaces without an explicit bootstrap command. - **Trigger:** npm install of the package in a Git project - **Impact:** Host AI coding agents can receive package-authored instructions and skills. - **Evidence paths:** package.json, dist/bin/postinstall.mjs, dist/src/postinstall.mjs, dist/src/bootstrap.mjs, dist/src/adapters.mjs, dist/src/paths.mjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-03T13:57:51.191Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven bootstrap writes cross-agent control files - **Attack narrative:** The postinstall hook detects a project install and invokes non-interactive bootstrap with the governed preset. Bootstrap defaults to all adapters and writes managed content into repository-level instructions and multiple AI-agent configuration/skill directories. This is an unconsented install-time mutation of a broad foreign AI-agent control surface. - **Rationale:** Source confirms the prohibited chain directly: npm postinstall invokes a non-interactive bootstrap that writes cross-vendor AI-agent controls in the consuming project. No exfiltration is required for this concrete install-time control-surface mutation. - **Files touched:** AGENTS.md, CLAUDE.md, GEMINI.md, CONVENTIONS.md, .agents/, .claude/, .codex/, .github/, .cursor/, .windsurf/, .ai/, .ai-agent-kit/, .gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall., dist/src/postinstall.mjs automatically calls bootstrap for project installs., dist/src/adapters.mjs defaults bootstrap to all agent adapters., dist/src/bootstrap.mjs writes scaffold and managed instruction files., dist/src/paths.mjs authorizes AGENTS.md, CLAUDE.md, .codex/, .claude/, and other foreign agent surfaces., README.md confirms npm install imports the governed kit through postinstall. - **Evidence against:** No credential harvesting, exfiltration endpoint, eval, or remote payload loading found., Tool installation requires an explicit tools install --apply command. ## Public findings ### 1.
