gm-plugkit@2.0.2514
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 install-time hook makes this unsuitable for a malicious block verdict. Its explicit-user-command agent-control mutation and remotely supplied executable daemon remain a material warning-level risk.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User runs `gm-plugkit`/`bun x gm-plugkit` or calls exported `ensureReady()`.
Impact
Can persist project-local agent instructions and cause agents to follow spool-delivered directives.
Mechanism
User-invoked agent-extension bootstrap, remote binary download, and daemon launch.
AI rationale
No install-time hook makes this unsuitable for a malicious block verdict. Its explicit-user-command agent-control mutation and remotely supplied executable daemon remain a material warning-level risk.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- `bootstrap-shared.js` appends `@.gm/next-step.md` to project `AGENTS.md`.
- `bootstrap.js` creates/changes project `CLAUDE.md`, `.gm/` instructions, and `.npmignore` during `ensureReady()`.
- `bootstrap.js` downloads and executes a native `agentplug-runner` daemon from GitHub Releases.
- Remote WASM/native integrity checks fetch SHA256 values from the same mutable release source.
- Bundled `SKILL.md` directs agents to follow daemon-provided instructions.
Evidence against
- `package.json` has no preinstall, install, or postinstall hook.
- Mutations and daemon startup occur only when the user invokes the `gm-plugkit` CLI.
- No source evidence of credential harvesting or data exfiltration.
