gm-plugkit@2.0.2480
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-aiNo lifecycle hook or import-time execution establishes malicious installation behavior. However, explicit execution installs remotely sourced agent instructions and executes a dynamically fetched native binary, so it warrants a warning.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Running gm-plugkit (default CLI or bootstrap entrypoint).
Impact
Remote release content can execute locally and influence agent behavior in the invoked project and user skill directories.
Mechanism
remote binary bootstrap plus AI-agent skill/config mutation
AI rationale
No lifecycle hook or import-time execution establishes malicious installation behavior. However, explicit execution installs remotely sourced agent instructions and executes a dynamically fetched native binary, so it warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bootstrap.js downloads platform-native agentplug-runner then executes it as a daemon.
- bootstrap.js fetches remote skill names/content and writes them into ~/.agents and ~/.claude skill directories.
- bootstrap-shared.js edits project CLAUDE.md and AGENTS.md to load .gm instructions.
- SKILL.md contains coercive agent-continuation and standing-approval instructions.
Evidence against
- package.json has no preinstall, install, or postinstall scripts.
- Network, writes, and daemon launch occur only after CLI/bootstrap invocation; index.js has no import-time action.
- Downloaded wasm/native runner paths are package-aligned and SHA-checked, though hashes come from the same remote release.
