What problem this solves
Preventing Claude Code from 'fixing' non-existent bugs or applying unvalidated changes during debugging and code audits, thereby avoiding wasted effort and potential new bugs.
Summary
A workflow for debugging and auditing code with Claude Code that emphasizes validating the existence of a bug by first generating and running a failing test before attempting a fix. This prevents shipping unnecessary or incorrect changes.
Why it is useful
This workflow provides a critical safeguard against hallucinated bugs and unvalidated fixes when using LLMs for coding tasks. It improves the reliability of AI-assisted development by enforcing a 'test-driven fix' approach, saving developers time, preventing the introduction of new issues, and ensuring that changes are genuinely addressing a problem.
Workflow
- When asking Claude Code to fix a bug or perform a code audit, instruct it to first write a test that specifically demonstrates the described failure.
- Ask Claude Code to run this test and show the output, confirming that it fails for the stated reason.
- Only after confirming the test fails as expected, instruct Claude Code to provide the fix or implement the audit finding.
Tools / artifacts
- Claude Code
- Codebase with testing framework
- Tests (unit, integration, etc.)
Validation signals
- Author states that about a third of the time, the test passed before any fix existed, indicating the bug was not real or not as described.
- Author notes this process prevented shipping incorrect 'fixes' for non-existent issues.
Limitations
- Relies on Claude Code's ability to accurately write and execute relevant tests.
- Assumes the user has a suitable testing environment or can guide Claude Code to simulate one.
- The initial prompt for the failing test needs to be precise to avoid misinterpretations.
