Autonomous code repair starts with understanding.

Codna starts by understanding the repository deterministically. That map reduces context, lowers cost, and gives the agent a narrower path to fix.

The result is a workflow where humans review root cause, blast radius, and test evidence instead of watching an agent search blindly through the codebase.

Core pattern

Map the repo with zero LLM tokens.
Identify suspect files and call paths.
Pack a small evidence bundle.
Generate a patch.
Verify and open a pull request.
