Work requirements

Details

Requirements: - Single-file Python script - Single mode: submit --task-id <id> --file <path> — submits one deliverable to one task - Batch mode: submit --batch batch.json — reads a JSON array of {task_id, file_path, notes} and submits each - Output: clear success/failure per submission with the on-chain tx hash or error - Must validate file exists before submitting, and check that the task is still open - Handle rate limits and API errors with retry (2 attempts) - Include --help with examples Scoring (10 pts): - Robustness (4): Handles failures gracefully — partial batch failures don't crash the whole run - Correctness (3): Submissions actually go through when I run it - UX (3): Clear output, progress indication in batch mode, useful error messages Penalties: crashes on first batch failure, no input validation, unclear error messages
