gm-plugkit@2.0.2497
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 explicit-user-command mutation of project and global AI-agent control surfaces plus remote executable loading. Under the install-control policy this warrants a warning, not a publish block, because there is no lifecycle trigger or confirmed malicious chain.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs gm-plugkit (for example bun x gm-plugkit).
Impact
Can replace global agent skills and alter project agent instructions, steering future agent behavior.
Mechanism
explicit agent-skill installation, remote binary bootstrap, and daemon launch
AI rationale
Source confirms explicit-user-command mutation of project and global AI-agent control surfaces plus remote executable loading. Under the install-control policy this warrants a warning, not a publish block, because there is no lifecycle trigger or confirmed malicious chain.

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bootstrap.js:803 runs project wiring on ensureReady.
- bootstrap-shared.js writes CLAUDE.md and AGENTS.md directives.
- bootstrap.js:664 overwrites global .agents/.claude skill files.
- bootstrap.js:611 can fetch skill content from GitHub main.
- bootstrap.js:938 downloads a native runner then executes it.
- SKILL.md directs agents to route work through its daemon.
Evidence against
- package.json has no lifecycle scripts.
- cli.js activates bootstrap only through explicit CLI invocation.
- bootstrap.js verifies downloaded artifact hashes before writes.
- No source evidence of credential harvesting or exfiltration.
