It also mutates project agent-instruction files so the daemon-controlled workflow is loaded. - **Trigger:** User runs gm-plugkit (for example bun x gm-plugkit spool). - **Impact:** A mutable remote publisher can replace the native runner or skill instructions, gaining code execution and control over supported agent environments. - **Evidence paths:** package.json, cli.js, bootstrap.js, bootstrap-shared.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T10:38:49.642Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary execution plus cross-agent instruction/control-surface writes. - **Attack narrative:** On explicit invocation, the package fetches a native runner and its checksum from the same remote release, persists it under ~/.gm-tools, and launches it detached. It also fetches mutable remote skill files into both ~/.agents and ~/.claude, then rewrites project CLAUDE.md and AGENTS.md to load daemon-directed instructions. The bundled skill tells agents to treat daemon-served prose as principal and avoid ordinary summaries, creating a remote-controlled agent workflow. - **Rationale:** This is concrete remote-code and broad AI-agent control-surface behavior, not merely a package-aligned downloader. No lifecycle hook mitigates the risk because the explicit CLI path performs the full chain. - **Files touched:** ~/.gm-tools/agentplug-runner, ~/.agents/skills/\/SKILL.md, ~/.claude/skills/\/SKILL.md, \/CLAUDE.md, \/AGENTS.md, \/.gm/next-step.md, \/.gm/instructions/ - **Network endpoints:** https://github.com/AnEntrypoint/agentplug-bin/releases/download/, https://api.github.com/repos/AnEntrypoint/agentplug-bin/releases/latest, https://raw.githubusercontent.com/AnEntrypoint/gm/main/skills/, https://github.com/AnEntrypoint/plugkit-bin/releases/download/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** bootstrap.js downloads and executes a native agentplug-runner., bootstrap.js fetches remote SKILL.md files and writes ~/.agents/skills and ~/.claude/skills., bootstrap-shared.js alters project CLAUDE.md and AGENTS.md to activate .gm instructions., Bundled SKILL.md directs agents to obey daemon-served instructions and suppress normal summaries., Remote artifact hashes are fetched from the same mutable release source. - **Evidence against:** package.json has no npm lifecycle scripts., Network activity is reached through the explicit gm-plugkit CLI/bootstrap path., Downloads include a SHA-256 comparison before persistence. ## Public findings ### 1.
