gm-plugkit@2.0.2536
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 has a concrete, high-risk remote execution and AI-agent configuration capability, but it is activated by an explicit CLI command and not by npm installation. That fits a warn verdict rather than a publish block under the supplied policy.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
User runs gm-plugkit CLI/bootstrap.
Impact
A remote-controlled binary and skill content can gain execution through the user-invoked daemon and influence supported agent environments.
Mechanism
Remote native payload execution plus AI-agent instruction-surface mutation.
AI rationale
The package has a concrete, high-risk remote execution and AI-agent configuration capability, but it is activated by an explicit CLI command and not by npm installation. That fits a warn verdict rather than a publish block under the supplied policy.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bootstrap.js:624 fetches skill content and writes it to ~/.agents and ~/.claude.
- bootstrap-shared.js:251 modifies project CLAUDE.md and AGENTS.md to load .gm instructions.
- bootstrap.js:931 downloads a native agentplug-runner and startSpoolDaemon executes it.
- bootstrap.js:798 invokes those mutations during the default CLI bootstrap path.
- Remote artifacts are verified only against hashes fetched from the same remote release.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- cli.js requires an explicit CLI invocation; importing index.js only exports functions.
- No source evidence of credential harvesting or data exfiltration.
