gm-plugkit@2.0.2478
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 creates persistent AI-agent extension/control surfaces and executes remotely obtained native code after an explicit CLI invocation. This meets a warning-level first-party agent-extension lifecycle risk, not the policy threshold for a publish block.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs gm-plugkit (for example through bun x/npx).
Impact
Can persist package-controlled instructions into project and user-level AI-agent skill surfaces and direct future agent behavior.
Mechanism
Remote agent-extension provisioning plus verified native-runner download and daemon spawn.
AI rationale
The package creates persistent AI-agent extension/control surfaces and executes remotely obtained native code after an explicit CLI invocation. This meets a warning-level first-party agent-extension lifecycle risk, not the policy threshold for a publish block.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bootstrap.js: ensureReady unconditionally calls agent-wiring on CLI bootstrap.
- bootstrap-shared.js writes project CLAUDE.md and appends .gm/next-step.md to AGENTS.md.
- bootstrap.js downloads remote SKILL.md files and writes them to ~/.agents/skills and ~/.claude/skills.
- bootstrap.js downloads, SHA-checks, then executes agentplug-runner as a detached daemon.
- The generated next-step instruction tells an agent to follow daemon-supplied imperatives.
Evidence against
- package.json has no preinstall, install, postinstall, or prepare hooks.
- The behavior is reached through the explicit gm-plugkit CLI command.
- Downloaded runner and wasm artifacts are SHA-256 checked before use.
- No source evidence of credential harvesting or unrelated data exfiltration.
