It changes the behavior of a separate AI agent without an explicit setup command. - **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:** 1.1.203 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically writes a persistent instruction file into the user's global Claude skills directory. That instruction declares itself active for every response. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-28T20:01:45.600Z - **Finished:** 2026-08-28T20:03:01.479Z - **Download time:** 1011 ms - **Static scan time:** 17947 ms - **AI review time:** 56920 ms - **Total time:** 75879 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically writes a persistent instruction file into the user's global Claude skills directory. That instruction declares itself active for every response. - **Trigger:** npm installation runs postinstall. - **Impact:** It changes the behavior of a separate AI agent without an explicit setup command. - **Evidence paths:** package.json, scripts/install-skills.cjs, .claude/skills/leanchy/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-28T20:03:01.479Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time global Claude skill injection. - **Attack narrative:** The package's postinstall hook discovers bundled skills and copies them into the user's global Claude configuration. The installed leanchy skill instructs Claude to apply a communication protocol to every response until disabled. This automatic, persistent modification targets a broad third-party AI-agent control surface and does not require the user to run a package setup command. - **Rationale:** The package automatically mutates the global Claude skills directory and installs instructions that take effect across Claude responses. This is unconsented install-time control-surface modification. - **Files touched:** .claude/skills/leanchy/SKILL.md, ~/.claude/skills/leanchy/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall hook copies a bundled skill into the user's global Claude configuration., The copied skill says it is active for every response, creating persistent agent-output control without a user command., The package also registers a command named claude that can shadow the expected Claude CLI when installed globally. - **Evidence against:** The install hook makes no network request and copies only the bundled skill file., No runtime self-dependency is declared in the manifest. ## Public findings ### 1.
