Unconsented modification of foreign AI-agent control surfaces can influence future agent behavior in the project. - **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:** 0.9.1 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall silently imports a large AI-agent scaffold into the consuming repository. It defaults to every supported third-party agent surface rather than requiring an explicit user command or adapter selection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-11T01:24:14.697Z - **Finished:** 2026-08-11T01:25:08.665Z - **Download time:** 1006 ms - **Static scan time:** 1266 ms - **AI review time:** 51693 ms - **Total time:** 53968 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall silently imports a large AI-agent scaffold into the consuming repository. It defaults to every supported third-party agent surface rather than requiring an explicit user command or adapter selection. - **Trigger:** npm install of the package as a project dependency or top-level install - **Impact:** Unconsented modification of foreign AI-agent control surfaces can influence future agent behavior in the project. - **Evidence paths:** package.json, dist/bin/postinstall.mjs, dist/src/postinstall.mjs, dist/src/bootstrap.mjs, dist/src/adapters.mjs, assets/enterprise-ai-agent-os/.ai/adapters/registry.json - **Review source:** ai\_review - **Reviewed:** 2026-08-11T01:25:08.665Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** non-interactive bootstrap writes broad AI-agent instructions, hooks, rules, and skills - **Attack narrative:** Installing the package executes postinstall, which calls bootstrap with --non-interactive and --yes. Bootstrap defaults to all adapters and writes packaged content into multiple third-party AI-agent configuration and skill locations in the target repository, including .claude, .codex, .cursor, and .github, without an explicit setup command or adapter consent. - **Rationale:** This is a concrete unconsented install-time mutation of broad foreign AI-agent control surfaces. Guardrails and lack of observed exfiltration do not remove that attack surface. - **Files touched:** AGENTS.md, CLAUDE.md, GEMINI.md, .claude/, .codex/, .cursor/, .github/, .ai-agent-kit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., dist/src/postinstall.mjs invokes bootstrap non-interactively with --yes., Bootstrap defaults to all adapters., dist/src/bootstrap.mjs writes agent config/skill surfaces., Registry targets Claude, Codex, Copilot, Cursor, and other agents. - **Evidence against:** No postinstall network request or credential harvesting found., Bootstrap validates paths and refuses symlink traversal., Runner blocks git write operations and remote API commands. ## Public findings ### 1.
