Example

Write a lint check to check for hardcoded values using regex or ast analysis.

The lint check should differentiate between constant declarations (typically in uppercase with underscores) and magic numbers in regular code.
The check should allow exceptions for commonly used numerical values (e.g., 0, 1, -1) and short, descriptive strings (e.g., "success", "error").
The check should be configurable, allowing developers to add or remove exceptions based on project-specific needs.

Example:

Good MAX_USERS = 100 result = "success"

Bad (would trigger a warning)
