Unconsented control of repository AI-agent behavior across installed tool surfaces. - **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:** 0.9.0 - **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 automatically imports a governed agent kit into the consuming repository. It mutates broad multi-vendor AI-agent instruction, skill, and configuration surfaces without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-09T15:29:57.704Z - **Finished:** 2026-08-09T15:30:47.367Z - **Download time:** 765 ms - **Static scan time:** 1096 ms - **AI review time:** 47800 ms - **Total time:** 49663 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically imports a governed agent kit into the consuming repository. It mutates broad multi-vendor AI-agent instruction, skill, and configuration surfaces without an explicit user command. - **Trigger:** npm install in a project that depends on the package - **Impact:** Unconsented control of repository AI-agent behavior across installed tool surfaces. - **Evidence paths:** package.json, dist/src/postinstall.mjs, dist/src/bootstrap.mjs, dist/src/file-ops.mjs, assets/enterprise-ai-agent-os/.ai/adapters/registry.json - **Review source:** ai\_review - **Reviewed:** 2026-08-09T15:30:47.367Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall auto-bootstrap of all AI-agent adapters - **Attack narrative:** On installation, the postinstall handler detects a project dependency and calls bootstrap non-interactively with automatic confirmation. Because no adapter selection is supplied, bootstrap selects every registered adapter and writes package-provided instructions and skills into numerous third-party AI-agent control surfaces in the consumer repository. - **Rationale:** This is a concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces. Safeguards against source-code changes and exfiltration do not remove that control-hijack behavior. - **Files touched:** package.json, dist/bin/postinstall.mjs, dist/src/postinstall.mjs, dist/src/bootstrap.mjs, dist/src/file-ops.mjs, dist/src/paths.mjs, assets/enterprise-ai-agent-os/.ai/adapters/registry.json, AGENTS.md, CLAUDE.md, GEMINI.md, CONVENTIONS.md, .aider.conf.yml, .ai/, .agents/, .claude/, .codex/ ### 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 invokes bootstrap with --yes., Bootstrap defaults to all adapters., Registry targets Codex, Claude, Cursor, Copilot, and other agent config surfaces., bootstrap writes generated instruction/skill files into those surfaces. - **Evidence against:** Postinstall limits writes to approved project configuration paths., Bootstrap rejects symlink paths and validates no application-source changes., No network or credential-exfiltration path is used by postinstall/bootstrap. ## Public findings ### 1.
