The remote skill and runner sources are not pinned to an immutable trusted artifact. - **Trigger:** User runs gm-plugkit, including the documented bun x gm-plugkit@latest spool command. - **Impact:** Remote publisher changes can execute code and alter agent behavior across the project and user skill directories. - **Evidence paths:** package.json, cli.js, bootstrap.js, bootstrap-shared.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T09:37:57.438Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote native payload execution plus AI-agent instruction-surface mutation. - **Attack narrative:** Running the CLI calls ensureReady, which wires project agent instructions and refreshes user-level skills. It discovers and downloads mutable remote skill content, then downloads a latest native runner with only a checksum fetched from that same remote publisher and starts it detached. The installed skill tells agents to follow daemon-served imperatives, creating a remote-controlled agent and code-execution chain. - **Rationale:** Source establishes a concrete remote payload-execution chain and broad AI-agent control-surface mutation during ordinary CLI use. The absence of lifecycle hooks reduces install-time exposure but does not remove the explicit runtime attack surface. - **Files touched:** CLAUDE.md, AGENTS.md, .gm/next-step.md, ~/.agents/skills/\/SKILL.md, ~/.claude/skills/\/SKILL.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/${tag}, https://raw.githubusercontent.com/AnEntrypoint/gm/main/skills/${skillName}/SKILL.md, https://api.github.com/repos/AnEntrypoint/gm/contents/skills?ref=main ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** bootstrap.js: ensureReady rewrites project CLAUDE.md/AGENTS.md wiring., bootstrap.js: downloads remote SKILL.md files and writes ~/.agents and ~/.claude skill paths., bootstrap.js: fetches latest native agentplug-runner and executes it as a detached daemon., Runner checksum is fetched from the same mutable GitHub release, not a package-pinned trust root., SKILL.md directs agents to follow daemon-provided imperative instructions. - **Evidence against:** package.json has no npm lifecycle hooks., Behavior is reached through the gm-plugkit CLI, not import-time., Wasm downloads are SHA-256 checked against a bundled or remote manifest. ## Public findings ### 1.
