gm-plugkit@2.0.2535
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 establishes an explicit-user-command AI-agent control-surface mutation and remote extension bootstrap. No install lifecycle hook, credential theft, or direct exfiltration was found.
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 (default/spool command) or calls ensureReady().
Impact
Agents may be redirected from user tasks to package-controlled imperative instructions across projects and agent homes.
Mechanism
AI-agent instruction injection plus remote bootstrap and daemon launch.
AI rationale
Source establishes an explicit-user-command AI-agent control-surface mutation and remote extension bootstrap. No install lifecycle hook, credential theft, or direct exfiltration was found.

Decision evidence
public snapshotAI called this Suspicious at 99.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bootstrap.js: ensureReady() runs project wiring and skill refresh.
- bootstrap-shared.js writes/edits CLAUDE.md and AGENTS.md to load .gm instructions.
- bootstrap.js installs SKILL.md files into ~/.agents and ~/.claude.
- SKILL.md directs agents to replace normal exits with daemon-supplied instructions.
- bootstrap.js fetches missing skills and native runner releases from GitHub at runtime.
- cli.js runs this path on explicit gm-plugkit invocation and starts the fetched runner.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- No credential harvesting or direct exfiltration is present in inspected JS.
