gm-plugkit@2.0.2476
Bootstrap and daemon-spawn tool for gm plugkit binary. Downloads the correct platform wasm, verifies SHA256, and launches agentplug-runner (the native wasm host) as the spool watcher daemon.
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package implements user-invoked AI-agent configuration and daemon deployment with remote executable/content delivery. Its broad control surface warrants a warning, but the absence of install-time activation or a concrete exfiltration/destructive chain does not support a malicious block.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs the gm-plugkit CLI or bootstrap.js.
Impact
Can influence AI-agent behavior in the current project and user skill directories; downloaded native code executes as a background spool daemon.
Mechanism
Remote skill provisioning, project instruction rewrites, native-runner download and daemon launch.
AI rationale
The package implements user-invoked AI-agent configuration and daemon deployment with remote executable/content delivery. Its broad control surface warrants a warning, but the absence of install-time activation or a concrete exfiltration/destructive chain does not support a malicious block.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- No lifecycle scripts in package.json.
- Explicit CLI path runs ensureReady and starts a detached agentplug-runner daemon.
- bootstrap-shared.js writes/prepends project CLAUDE.md and AGENTS.md directives.
- bootstrap.js refreshes skills into ~/.agents/skills and ~/.claude/skills, including remotely fetched content.
- bootstrap.js downloads and executes a native runner from GitHub Releases.
- Bundled SKILL.md directs agent workflow through the installed spool daemon.
Evidence against
- Agent-control changes require explicit gm-plugkit CLI/bootstrap execution, not npm install.
- No source evidence of credential harvesting or network exfiltration.
- Downloads are constrained to named AnEntrypoint GitHub/npm endpoints and SHA-256 checked.
