momentic@3.51.4
 [![npm]](https://www.npmjs.com/package/momentic)
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package is not malicious by the stated boundary, but its explicit command can extend coding-agent behavior across several platforms. Warn rather than block because the integration is user-invoked and source-aligned.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Explicit `momentic install-skills` invocation with an editor selection.
Impact
Adds testing-agent instructions and capabilities to a project agent environment.
Mechanism
Writes packaged SKILL.md files into selected project agent-skill directories.
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit legacy `install-skills` command writes package skills into Cursor, Claude, Codex, OpenCode, or Copilot project directories.
- The CLI exposes AI-driven browser-test actions and networked Momentic API access.
- This is an explicit user-command agent integration, not an install-time hook.
Evidence against
- package.json has no preinstall, install, postinstall, or prepare lifecycle script.
- Only a user-invoked bin entrypoint is declared.
- No confirmed credential harvesting, unofficial credential gateway, remote payload execution, or stealth persistence was found.
- The skill files describe Momentic E2E testing behavior.
