🐛 Bug Fixer

A persistent agent that finds and fixes bugs. Remembers your codebase.

USAGE:
  bun cli.ts [bug description]     Fix a specific bug
  bun cli.ts                       Interactive mode
  bun cli.ts --status              Show agent status
  bun cli.ts --reset               Reset agent (forget everything)
  bun cli.ts -h, --help            Show this help

EXAMPLES:
  bun cli.ts "the tests in auth.test.ts are failing"
  bun cli.ts "TypeError on line 42 of utils.ts"
  bun cli.ts "npm run build shows an error about missing module"

HOW IT WORKS:
  1. Describe the bug (error message, failing test, unexpected behavior)
  2. The agent explores your codebase to understand the context
  3. It identifies the root cause and makes a fix
  4. It runs tests or commands to verify

PERSISTENCE:
  The agent remembers your codebase across sessions. The more you use it,
  the better it knows where things are and what patterns to look for.
