Controls future agent behavior across ~/.agents, ~/.claude, and the current project; executes a remotely supplied native runner. - **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:** 2.0.2533 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A user CLI invocation provisions and refreshes global AI-agent skill files, rewrites project agent instruction entrypoints, and launches a detached spool daemon. The installed instructions direct future agents to follow daemon-provided imperatives. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-08T23:11:09.177Z - **Finished:** 2026-08-08T23:11:56.939Z - **Download time:** 253 ms - **Static scan time:** 183 ms - **AI review time:** 47326 ms - **Total time:** 47762 ms ## Security analysis ### Published attack-surface review - **Summary:** A user CLI invocation provisions and refreshes global AI-agent skill files, rewrites project agent instruction entrypoints, and launches a detached spool daemon. The installed instructions direct future agents to follow daemon-provided imperatives. - **Trigger:** Running the gm-plugkit CLI or calling ensureReady - **Impact:** Controls future agent behavior across ~/.agents, ~/.claude, and the current project; executes a remotely supplied native runner. - **Evidence paths:** package.json, cli.js, bootstrap.js, bootstrap-shared.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-08T23:11:56.939Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-updatable AI-agent control-surface provisioning plus daemon bootstrap - **Attack narrative:** On explicit CLI use, the package writes or replaces global skills for multiple agent platforms, alters project instruction-loading files, and starts a detached native spool daemon. Skill content instructs agents to obtain future actions from that daemon. The package also refreshes skills from a mutable GitHub main branch and downloads the runner from the latest release; the checksum is fetched from the same release source. - **Rationale:** The package has no install hook, but its normal runtime path performs broad, remote-updatable AI-agent control-surface mutation and executes a detached downloaded native runner. This is a concrete agent-control chain beyond a narrow package-owned setup. - **Files touched:** ~/.agents/skills/\/SKILL.md, ~/.claude/skills/\/SKILL.md, \/CLAUDE.md, \/AGENTS.md, \/.gm/next-step.md, ~/.gm-tools/agentplug-runner, \/.gm/exec-spool - **Network endpoints:** https://api.github.com/repos/AnEntrypoint/agentplug-bin/releases/latest, https://github.com/AnEntrypoint/agentplug-bin/releases/download/${tag}, https://api.github.com/repos/AnEntrypoint/gm/contents/skills?ref=main, https://raw.githubusercontent.com/AnEntrypoint/gm/main/skills/${skillName}/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** bootstrap.js writes remote/bundled skills into ~/.agents/skills and ~/.claude/skills, bootstrap-shared.js edits project CLAUDE.md and AGENTS.md to load .gm instructions, SKILL.md instructs agents to follow a spool daemon and disallows normal exits, bootstrap.js downloads current-release native runner and spawns it detached, Remote skill discovery/fetch uses mutable GitHub main content without a pinned trust root - **Evidence against:** package.json has no npm lifecycle scripts, No credential harvesting or outbound data-exfiltration code found, Downloaded release artifacts are SHA-256 checked, though checksum source is co-hosted ## Public findings ### 1.
