This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 98.0% - **Started:** 2026-08-09T13:21:41.325Z - **Finished:** 2026-08-09T13:22:17.504Z - **Download time:** 513 ms - **Static scan time:** 164 ms - **AI review time:** 35502 ms - **Total time:** 36179 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicit gm-plugkit CLI invocation modifies project and AI-agent instruction surfaces, downloads a native runner, and starts it detached. The runner and remotely refreshed skills can influence subsequent agent behavior. - **Trigger:** User runs the gm-plugkit CLI or calls ensureReady/startSpoolDaemon. - **Impact:** Project guidance and global agent skill files may be changed; remotely supplied executable and skill content gains control over the spool workflow. - **Evidence paths:** package.json, index.js, cli.js, bootstrap.js, bootstrap-shared.js, bootstrap-wasm-core.js, SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-09T13:22:17.504Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote agent-extension provisioning and detached native daemon execution. - **Rationale:** This is not an install-time malware chain, but its explicit CLI path provisions broad agent-control surfaces and executes remotely downloaded native code. The package warrants a warning for dangerous AI-agent capability abuse. - **Files touched:** .gm/next-step.md, .gm/instructions/\*\*, .gm/exec-spool/\*\*, CLAUDE.md, AGENTS.md, .npmignore, ~/.agents/skills/\*/SKILL.md, ~/.claude/skills/\*/SKILL.md, ~/.gm-tools/agentplug-runner, ~/.gm-tools/plugkit.wasm - **Network endpoints:** https://api.github.com/repos/AnEntrypoint/agentplug-bin/releases/latest, https://github.com/AnEntrypoint/agentplug-bin/releases/download/${tag}, https://github.com/AnEntrypoint/plugkit-bin/releases/download/v${version}, https://api.github.com/repos/AnEntrypoint/gm/contents/skills?ref=main, https://raw.githubusercontent.com/AnEntrypoint/gm/main/skills/${skillName}/SKILL.md, https://registry.npmjs.org/gm-plugkit/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 98.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** bootstrap.js: ensureReady modifies project .gm, CLAUDE.md, AGENTS.md, and .npmignore., bootstrap.js: ensureSkillMdFresh writes skill files under ~/.agents and ~/.claude., bootstrap.js downloads a platform-specific agentplug-runner and executes it as a detached spool daemon., bootstrap.js fetches remote skill names/content from GitHub, then installs them into agent skill directories., Bundled SKILL.md directs agents to use the daemon and follow returned instructions. - **Evidence against:** package.json has no preinstall, install, postinstall, or other lifecycle hook., Side effects require explicit CLI/runtime invocation; index.js only exports functions., No credential harvesting or source-level data exfiltration was found. ## Public findings ### 1.
