- **Category:** config_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

setup.py uses deprecated parameter names like 'description' instead of 'description', or other outdated setuptools APIs.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.8 | active | — | — |
| 3.9 | active | — | — |
| 3.10 | active | — | — |
| 3.11 | active | — | — |

## Workarounds

1. **** (95% success)
   ```
   Update setup.py to use underscore-separated parameters: `description='...'`.
   ```
2. **** (90% success)
   ```
   Use setup.cfg with proper keys: `[metadata] description = ...`.
   ```
3. **** (70% success)
   ```
   Run `python -m pip install --upgrade setuptools` and then fix any remaining warnings.
   ```

## Dead Ends

- **** — Future setuptools versions will break; the warning is a sign of impending failure. (40% fail)
- **** — This may cause conflicts or warnings; better to migrate fully. (50% fail)
- **** — This is the opposite direction; dash-separated is being deprecated. (80% fail)
