  Confidence changes required: 0%
  The error message in the fetch_expected_integration_params function was updated to use app.name!r and auth_scheme!r for better readability and consistency. This is a good change as it improves the clarity of the error message.

2. python/composio/tools/toolset.py:1387

• Draft comment:
  Changed auth_scheme default to None to allow dynamic fetching of default auth scheme from API.
• Reason this comment was not posted:
  Confidence changes required: 0%
  The auth_scheme parameter in the initiate_connection function was changed from a default value of "OAUTH2" to None. This allows the function to dynamically fetch the default auth scheme from the API if not provided, which is a more flexible approach.

3. python/composio/tools/toolset.py:1401

• Draft comment:
  Updated auth_scheme check to handle None values appropriately.
• Reason this comment was not posted:
  Confidence changes required: 0%
  The check for auth_scheme in initiate_connection was updated to handle None values, which is necessary due to the change in default value. This ensures that the function behaves correctly when auth_scheme is not provided.

The docstring for initiate_connection should be updated to reflect that auth_scheme is now optional and will be fetched from the API if not provided. This helps maintain clear documentation for future developers.

Code Review Summary

Overall Assessment

The changes look good and improve the authentication scheme handling by making it more flexible and user-friendly. The code is clean and the error messages are more informative.

Strengths

✅ Good error message improvements using repr() for better clarity
✅ Removal of duplicate auth_scheme validation
✅ Clean implementation of default auth scheme fetching
✅ Backward compatible changes

Suggestions for Improvement

1. Update the docstring for initiate_connection to reflect the new optional behavior
2. Add error handling and logging around the default auth scheme fetching
3. Consider standardizing error message formatting across the codebase (some use backticks, others use repr())

Testing Recommendations

• Add tests for automatic auth scheme selection
• Test error cases when API calls fail
• Verify backward compatibility with existing code

The changes are well-structured and improve the codebase. With the suggested improvements implemented, this PR will be ready to merge.
