🎨 Palette: Interactive input validation & cleanup by google-labs-jules[bot] · Pull Request #133 · abhimehro/ctrld-sync

google-labs-jules · 2026-01-25T22:58:47Z

Improved CLI UX by adding interactive input validation loops for Profile ID and API Token prompts. This prevents the script from starting with invalid credentials and provides immediate feedback to the user. Also cleaned up some duplicate code.

PR created automatically by Jules for task 5319312495894963983 started by @abhimehro

- Add `get_validated_input` helper for robust interactive prompts. - Validate Profile ID format immediately during input. - Prevent empty API Token input. - Refactor `validate_profile_id` to separate logic from logging. - Remove duplicate `MAX_RESPONSE_SIZE` constant. - Update `palette.md` with UX learnings.

Pull request overview

This PR enhances the CLI user experience by adding interactive input validation loops for Profile ID and API Token prompts. The changes prevent the script from proceeding with invalid credentials by validating input immediately and providing clear error messages. The PR also includes code cleanup by removing a duplicate constant definition.

Changes:

Added get_validated_input function to enable validation loops for interactive prompts
Refactored profile ID validation by extracting format checking into a separate is_valid_profile_id_format function
Updated interactive prompts in main() to use the new validation function for both Profile ID and API Token inputs
Removed duplicate MAX_RESPONSE_SIZE constant definition
Added documentation of the interactive validation pattern to .Jules/palette.md

main.py

+def validate_profile_id(profile_id: str) -> bool:
+    if not is_valid_profile_id_format(profile_id):
+        if not re.match(r"^[a-zA-Z0-9_-]+$", profile_id):
+            log.error("Invalid profile ID format (contains unsafe characters)")
+        elif len(profile_id) > 64:
+            log.error("Invalid profile ID length (max 64 chars)")
        return False
    return True


The validate_profile_id function contains redundant validation logic. After calling is_valid_profile_id_format (line 277), the function re-checks the same conditions (regex match on line 278 and length check on line 280) that were already validated inside is_valid_profile_id_format. This duplicates the validation logic and makes the code harder to maintain. Consider simplifying this function to only call is_valid_profile_id_format and provide appropriate error messages based on which specific check failed, or refactor is_valid_profile_id_format to return more detailed information about why validation failed.

The new get_validated_input function and is_valid_profile_id_format function lack test coverage. While the test file (test_main.py) includes tests for other functions like check_api_access, push_rules, and interactive prompts, there are no tests for these new validation functions. Since the codebase has comprehensive test coverage for similar functions, these new functions should also be tested to ensure they work correctly, especially for edge cases like empty input, whitespace-only input, invalid characters, and length boundaries.

This 'lambda' is just a simple wrapper around a callable object. Use that object directly.
