Run overnight in your project. Chat to generate detailed specs.
Approve the specs and go to bed. Agents work through the night.
Wake up to commits, tests, and a summary. Iterate and repeat.
Agents verify their work twice. Only stops when 2 consecutive passes find zero defects.
Every task tracked: scope, duration, defects found, defects fixed. Full visibility.
Agents score themselves and learn from mistakes. Gets better over time.
