| Key features | - Session recovery across 31 AI coding tools including Claude, Cursor, Codex, Gemini, Cline, Devin, Windsurf, and more
- Git-aware state tracking with branch, diff, changed files, and recent commits
- Dependency graph showing file relationships and god-node detection
- 49 MCP tools callable directly from Claude Code, Cursor, Devin, and Windsurf
- Session Vault for local recovery history after crashes and outages
- Zero telemetry with local recovery and optional explicit exports only
- Hivy on-device intelligence for context trimming and drift detection
- Windows, macOS, and Linux desktop apps with CLI and VS Code/Cursor extension
- Council 12-agent review layer for risky handoffs to surface stale assumptions
| - 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

| What makes it different | - Recovers from disk state without needing the old session alive, unlike transcript-based approaches
- Works after the session ends or is locked out, unlike /compact or /handoff skills
- Formats for 31 AI tools instead of locking you into one platform
- Local-first with zero telemetry and no cloud sync unless explicitly configured
| - 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
