Autonomous
Checksum is a background agent, not a copilot. You give it a task (generate 20 tests, 200 tests) and it works independently. No prompting back and forth. No waiting for each response. The agent goes to work and returns finished results.
Why it matters: 

‍Coding copilots like Claude Code require constant conversation: prompt, wait, check, run, repeat. With Checksum's high accuracy, you can trust it to work autonomously. This is what enables scale: let it generate hundreds of tests while you do other work.
