| Key features | - Configure plugins, skills, MCP servers, and hooks in a single harness.yaml file
- Observatory: monitor every session, tool call, and minute of activity
- Memory: persistent knowledge graph for AI orientation
- Comparator: run prompts across Claude Code, Cursor, and Copilot side by side
- Import existing configs from multiple AI coding tools automatically
- Share complete setup via single file with teammates
- Harness Parity: verify all connected AI tools end up with identical configuration
- Cross-harness compatibility table showing actual tool capabilities
| - Schedule Python scripts to run from every 5 minutes to monthly on any timezone
- Receive webhooks and run automations on external events
- Store persistent state between runs with JSON values and counters
- Call any HTTPS API with saved secrets and connected accounts
- Send emails and post to Slack from automations
- Built-in Gemini AI model for text classification and summarization
- Full run logs with secrets masked and failure notifications
- Use CLI or MCP to set up and manage automations
- Approve all actions including turning on, running now, and deleting

| What makes it different | - Import-first approach: reads existing configs from all your tools and converges them before you write YAML
- No marketing gloss: capability table generated at build time from actual adapter code, not hand-maintained
- Portable across tools: single harness.yaml travels with you to every machine and tool
- Open source and free: no cost beyond existing Claude subscription
- Based on open specification: Harness Protocol is vendor-neutral and JSON Schema validated
| - Keeps user fully in control with approval required for all actions
- Never exposes API keys to the assistant, keys stay in the dashboard
- Works with multiple AI assistants including ChatGPT, Claude and Cursor
- One command works for both Node.js and Python installations
