Modifies broad project AI-agent instruction and configuration surfaces, including AGENTS.md, CLAUDE.md, GEMINI.md, and adapter files. - **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:** 1.5.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm installation, the package automatically imports a governed kit into the consumer project. This writes AI-agent control/configuration files without a user command or approval. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-21T01:07:05.878Z - **Finished:** 2026-08-21T01:08:12.232Z - **Download time:** 753 ms - **Static scan time:** 3315 ms - **AI review time:** 62283 ms - **Total time:** 66354 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm installation, the package automatically imports a governed kit into the consumer project. This writes AI-agent control/configuration files without a user command or approval. - **Trigger:** npm postinstall during a qualifying project install. - **Impact:** Modifies broad project AI-agent instruction and configuration surfaces, including AGENTS.md, CLAUDE.md, GEMINI.md, and adapter files. - **Evidence paths:** package.json, dist/src/postinstall.mjs, dist/src/adapters.mjs, dist/src/bootstrap.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-21T01:08:12.232Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Non-interactive bootstrap of all AI-agent adapters into the install target. - **Attack narrative:** Installing the dependency triggers postinstall. For a project dependency or top-level npm install, it invokes bootstrap with --non-interactive and --yes; bootstrap selects every adapter by default and writes generated agent configuration and managed instruction sections into the consumer repository. This is an unconsented install-time mutation of a broad foreign AI-agent control surface. - **Rationale:** The automatic lifecycle path performs broad AI-agent configuration writes in the consuming project without an explicit user command. That meets the install-control-surface block criterion despite no observed postinstall exfiltration. - **Files touched:** AGENTS.md, CLAUDE.md, GEMINI.md, CONVENTIONS.md, .ai/, .agents/, .claude/, .codex/, .cursor/, .ai-agent-kit/installation.json, .gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Lifecycle hook invokes postinstall., Postinstall non-interactively bootstraps into the installing project with --yes., Bootstrap defaults to all adapters and writes AI-agent instruction/configuration paths. - **Evidence against:** No credential harvesting or network request occurs in the postinstall path., Bootstrap states it does not install global tools. ## Public findings ### 1.
