Explicit gm-plugkit CLI use downloads and executes a native runner, then provisions persistent agent skills and project instruction wiring. The installed skill directs agents to a local daemon instruction channel. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-09T10:28:08.230Z - **Finished:** 2026-08-09T10:28:52.353Z - **Download time:** 502 ms - **Static scan time:** 186 ms - **AI review time:** 43435 ms - **Total time:** 44123 ms ## Security analysis ### Published attack-surface review - **Summary:** Explicit gm-plugkit CLI use downloads and executes a native runner, then provisions persistent agent skills and project instruction wiring. The installed skill directs agents to a local daemon instruction channel. - **Trigger:** User runs gm-plugkit (for example via bun x/npx). - **Impact:** Can influence future Claude/agent behavior and execute opaque downloaded runner code. - **Evidence paths:** package.json, cli.js, bootstrap.js, bootstrap-shared.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T10:28:52.353Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote native-runner bootstrap plus AI-agent skill/config provisioning. - **Rationale:** This is a concrete, explicit-user-command agent-extension bootstrap with broad persistent AI-agent configuration effects and opaque native code execution. It lacks lifecycle-based unconsented execution, so policy supports warning rather than blocking. - **Files touched:** ~/.gm-tools/agentplug-runner, ~/.agents/skills/\/SKILL.md, ~/.claude/skills/\/SKILL.md, \/.gm/next-step.md, \/CLAUDE.md, \/AGENTS.md - **Network endpoints:** https://api.github.com/repos/AnEntrypoint/agentplug-bin/releases/latest, https://github.com/AnEntrypoint/agentplug-bin/releases/download/, https://github.com/AnEntrypoint/plugkit-bin/releases/download/, https://raw.githubusercontent.com/AnEntrypoint/gm/main/skills/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** bootstrap.js installs fetched native agentplug-runner and runs it detached., bootstrap.js writes ~/.agents/skills and ~/.claude/skills SKILL.md files., bootstrap-shared.js modifies project CLAUDE.md and AGENTS.md to load .gm instructions., Bundled SKILL.md directs agents to follow daemon-provided instructions. - **Evidence against:** package.json has no preinstall/install/postinstall scripts., All mutation and daemon setup follows explicit CLI execution., Remote binaries are SHA-256 checked before installation., No credential harvesting or unrelated exfiltration found. ## Public findings ### 1.
