gm-plugkit@2.0.2468
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, persistent AI-agent control surface and executes a remotely updated native component, but source inspection found no lifecycle hook, credential theft, or other concrete malicious payload. This meets the explicit-user-command agent-config mutation warning boundary.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
User runs gm-plugkit CLI or calls ensureReady/bootstrap.
Impact
Can alter future AI-agent behavior and execute a remotely supplied native runner in the user's environment.
Mechanism
explicit agent-config mutation plus verified remote native-runner download and execution
AI rationale
The package has a concrete, persistent AI-agent control surface and executes a remotely updated native component, but source inspection found no lifecycle hook, credential theft, or other concrete malicious payload. This meets the explicit-user-command agent-config mutation warning boundary.

Decision evidence
public snapshotAI called this Suspicious at 93.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bootstrap.js:571-640 installs bundled skill files into ~/.agents/skills and ~/.claude/skills.
- SKILL-gm-continue.md requires repeated agent dispatches and discourages deferring to the user.
- bootstrap-shared.js:251-289 creates/edits project CLAUDE.md and AGENTS.md to load .gm instructions.
- bootstrap.js:841-878 downloads a native runner, verifies its hash from the same release, and cli.js executes it.
- package.json has no lifecycle scripts; this occurs on explicit CLI/bootstrap use.
Evidence against
- No install, preinstall, or postinstall hook is declared.
- No credential harvesting or data-exfiltration code was found.
- Network targets are package-associated GitHub releases/API and npm registry.
- Project and agent-skill writes are reached through user-invoked CLI/bootstrap paths.
