Explicit gm-plugkit CLI use downloads a verified native runner, starts a spool daemon, and installs agent/project instruction wiring. This creates a package-owned agent control surface but no unconsented install-time activation is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-09T14:36:24.444Z - **Finished:** 2026-08-09T14:37:12.451Z - **Download time:** 505 ms - **Static scan time:** 188 ms - **AI review time:** 47313 ms - **Total time:** 48007 ms ## Security analysis ### Published attack-surface review - **Summary:** Explicit gm-plugkit CLI use downloads a verified native runner, starts a spool daemon, and installs agent/project instruction wiring. This creates a package-owned agent control surface but no unconsented install-time activation is present. - **Trigger:** User runs gm-plugkit CLI or calls ensureReady. - **Impact:** Daemon-controlled instructions can influence coding-agent behavior and persist skill/config files. - **Evidence paths:** package.json, cli.js, bootstrap.js, bootstrap-shared.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T14:37:12.451Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote native runner bootstrap plus AI-agent skill/config provisioning - **Rationale:** The package has a real, explicit-user-triggered agent extension and remote executable bootstrap capability. It is risky enough to warn, but does not meet the policy threshold for malicious blocking because it lacks unconsented install-time or broad foreign control-surface mutation. - **Files touched:** ~/.gm-tools/agentplug-runner, ~/.agents/skills/\/SKILL.md, ~/.claude/skills/\/SKILL.md, \/CLAUDE.md, \/AGENTS.md, \/.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 ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** bootstrap.js fetches and executes a native agentplug-runner daemon., bootstrap.js writes ~/.agents and ~/.claude skill files., bootstrap.js modifies project CLAUDE.md and AGENTS.md., SKILL.md directs agents to treat daemon instruction responses as authoritative. - **Evidence against:** package.json has no lifecycle scripts., Activation is explicit CLI/import use, not install-time., Downloaded runner and wasm are SHA-256 checked., No source evidence of credential harvesting or exfiltration. ## Public findings ### 1.
