gm-plugkit@2.0.2475
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-aiThis is an explicit-user-command agent-control and remote-code-loading capability, not an install-time attack, so a warning is appropriate rather than a publish block. The mutable remote skill installation and persistent AI-agent configuration changes are concrete unresolved risk.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs the gm-plugkit CLI or calls ensureReady/bootstrap.
Impact
Persistent AI-agent behavior changes and execution of remotely supplied native code.
Mechanism
remote skill installation plus downloaded daemon execution
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bootstrap.js: ensureReady writes project agent wiring on CLI bootstrap.
- bootstrap-shared.js creates/edits CLAUDE.md and AGENTS.md.
- bootstrap.js refreshes skills into ~/.agents/skills and ~/.claude/skills.
- bootstrap.js discovers remote skill names from a mutable GitHub branch.
- bootstrap.js downloads a native runner and executes it as a detached spool daemon.
- Bundled SKILL.md directs agents to continue dispatching rather than end normally.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- index.js only exports functions; import alone does not bootstrap.
- Network and daemon actions require explicit CLI/bootstrap execution.
- No source evidence of credential harvesting or exfiltration.
