ubx fix runs ubx validate, sends errors and source code to Claude, and proposes fixes as a unified diff with a confirmation prompt.
Requires UBX_AI_API_KEY or ai.api_key in ubx.yaml.

​
Usage

ubx fix [path] [flags]

​
Examples

ubx fix                  # fix all errors in current directory
ubx fix main.iac         # fix specific file
ubx fix --dry-run        # show proposed diff without writing
ubx fix --yes            # apply fixes without confirmation

​
Flags

​
Behaviour

  • If no errors → exits 0 with ”✓ no errors found”
  • If errors → sends source + errors to Claude, shows diff, prompts
  • --dry-run shows diff but never writes
  • --yes applies without prompting (CI/CD)
