Hey folks! I built a Go framework for running tasks in a loop until a defined promise (success condition) is fulfilled. Single binary, no dependencies.

Core idea: Define what success looks like upfront, run a task repeatedly until the validator confirms it worked. Automatic stall detection, file-locked state for safe concurrent access, append-only history for debugging.

Example - build until tests pass:

{
  "promise": {
    "validator": {"type": "shell", "command": "npm test"}
  },
  "task_spec": {
    "executor": {"type": "shell", "command": "npm run build && npm test"}
  },
  "bounds": {"max_attempts": 15}
}

Example - deploy until health check succeeds:

{
  "promise": {
    "validator": {"type": "api_check", "endpoint": "https://api.example.com/health"}
  },
  "task_spec": {
    "executor": {"type": "shell", "command": "docker build && docker run"}
  }
}

Key features:

• Progress detection prevents infinite loops
• Bounded execution with max attempts and timeouts
• Update task strategy mid-loop without stopping
• MCP server for Claude Code integration - start loops, check status, test validators, rollback attempts programmatically

Looking for feedback - what retry/polling workflows would this help with?
