gm-plugkit@2.0.2477
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-aiSource confirms a user-invoked AI-agent control-surface mutation and opaque remote native execution. No lifecycle hook, credential theft, or direct JS exfiltration was found, so policy calls for a warning rather than a block.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Explicit `gm-plugkit`/bun x CLI invocation.
Impact
A project AI agent can be steered through package-controlled spool instructions; downloaded native code executes outside the inspected JS source.
Mechanism
Project agent-instruction mutation plus remote native-runner download and daemon launch.
AI rationale
Source confirms a user-invoked AI-agent control-surface mutation and opaque remote native execution. No lifecycle hook, credential theft, or direct JS exfiltration was found, so policy calls for a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bootstrap-shared.js mutates project AGENTS.md and CLAUDE.md.
- It creates .gm/next-step.md directing an agent to follow returned imperatives.
- cli.js explicitly starts a detached spool daemon on user invocation.
- bootstrap.js downloads and executes agentplug-runner from GitHub releases.
- bootstrap.js refreshes bundled skill content from AnEntrypoint/gm.
Evidence against
- package.json contains no npm lifecycle scripts.
- JS source shows no credential harvesting or direct exfiltration.
- The bootstrap/download path is reached through the explicit CLI, not import-time.
