One prompt, zero config hell.</p> <p><strong>⚑ What it does:</strong></p> <ul> <li>🧠 Smart routing β€” says "plan this", "debug that", "review this PR" and sends it to the specialist that handles it best</li> <li>⚑ Instant response β€” you never wait at a blank screen. Agents work async, results appear when done</li> <li>πŸ“Š Live status β€” every 2 minutes, a heartbeat tree shows exactly which agent is running, blocked, or done</li> <li>πŸ”„ Auto fallback β€” rate limit hit? Switches to the next best model. You never notice</li> <li>πŸ›‘οΈ No hallucination β€” hard constraints: never invent files, never guess imports, always search first</li> <li>πŸ’°Cost smart β€” simple tasks get cheap fast models, complex ones get deep reasoning. No waste</li> </ul> <p><strong>πŸ‘€ What a session looks like:</strong></p> <p>πŸ”€ Router</p> <p>β”œβ”€β”€ πŸ—οΈ plan (Microservices arch) β†’ [RUNNING]</p> <p>β”œβ”€β”€ ⚑ fast (Find auth module) β†’ [FINISHED: src/auth/]</p> <p>└── πŸ“‹ Summary: Architecture in progress, auth found</p> <p><strong>πŸ› οΈ Setup:</strong></p> <p>Drop 2 files in your OpenClaw workspace. That's it.</p> <ul> <li><p>AGENTS.md β†’ the router prompt</p></li> <li><p>openclaw.json β†’ the agent definitions with fallback chains</p></li> </ul> <p>Works with OpenCode models out of the box, or swap in any provider you want.</p> <p><strong>πŸ”— Full config + docs:</strong> <a href="https://github.com/FaridLU/openclaw-task-router" rel="noopener noreferrer">https://github.com/FaridLU/openclaw-task-router</a></p> <p>MIT licensed.
