## FAQ

### Which agent runtimes can Trinity run?

Trinity can run agents on Claude Code, OpenAI Codex or Gemini CLI.

### Is Trinity self-hosted and open source?

Yes, Trinity is open source under Apache 2.0 and runs on your own infrastructure with Docker.

### Can Trinity require human approval before an agent acts?

Yes. Marking a skill as gated freezes requests for it until a named approver approves or rejects them in their Inbox.

### Where can agents be reached from besides the web UI?

Agents also answer in Slack, Telegram and WhatsApp, on phone calls, over a public chat link, over MCP and from the CLI.

### Does Trinity keep an audit log of agent actions?

Yes, every tool call lands in an append-only audit log, with an optional SHA-256 hash chain in compliance mode.
