gm-plugkit@2.0.2443
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-aiNo lifecycle hook establishes an automatic install-time compromise, so a block is not warranted under policy. The explicit command nevertheless performs broad AI-agent configuration writes and accepts mutable remote instruction content.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs gm-plugkit (for example via bun x/npx) or invokes its bootstrap entrypoint.
Impact
Can alter AI-agent behavior across the current project and user profile; remotely sourced instructions are trusted without a pinned content hash.
Mechanism
remote skill provisioning, project instruction wiring, WASM download, and daemon launch
AI rationale
No lifecycle hook establishes an automatic install-time compromise, so a block is not warranted under policy. The explicit command nevertheless performs broad AI-agent configuration writes and accepts mutable remote instruction content.

Decision evidence
public snapshotAI called this Suspicious at 93.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bootstrap.js fetches SKILL.md from GitHub main and writes it to ~/.agents and ~/.claude.
- bootstrap-shared.js mutates project CLAUDE.md and AGENTS.md to load .gm instructions.
- Bundled SKILL.md directs agents to continue work indefinitely and avoid prose-only completion.
- bootstrap.js downloads and launches a remote plugkit WASM through agentplug-runner.
Evidence against
- package.json has no npm lifecycle scripts.
- Risky behavior is activated by the explicit gm-plugkit CLI/bootstrap command.
- WASM downloads are SHA-256 checked when a remote or bundled manifest is available.
- No credential harvesting or direct exfiltration code found.
