## Implementation Complete ### What was done: 1. Added `browser-cookie3>=0.20.0` dependency to pyproject.toml 2. Created `src/kafkactl/auth.py` with: - `extract_cf_cookie(domain: str) -> Optional[str]` - main function - `_get_chrome_cookie(domain: str)` - Chrome cookie extraction - `_get_firefox_cookie(domain: str)` - Firefox cookie extraction - `_get_safari_cookie(domain: str)` - Safari cookie extraction 3. Created comprehensive unit tests in `tests/test_auth.py` (14 tests) ### How it works: - Tries Chrome first (most common browser) - Falls back to Firefox if Chrome fails/no cookie - Falls back to Safari if Firefox fails/no cookie - Returns None if no cookie found in any browser - All exceptions are caught and logged, never crashes ### Verification: - All 24 tests pass (14 new auth tests + 10 existing config tests) - Tested with mocked browser cookie stores ### Files changed: - `pyproject.toml:23-28` - Added browser-cookie3 dependency - `src/kafkactl/auth.py` - New 84-line module - `tests/test_auth.py` - New 262-line test file ### Commit: 9ddaed5 KAFKA-1: Add browser cookie extraction for CF_Authorization

## Feature Triage Complete **Status:** NOT IMPLEMENTED **Summary:** This feature does not exist in the codebase. The requested browser-cookie3 integration for extracting CF_Authorization cookies is a straightforward implementation with low complexity. **Implementation Location:** - New file: `src/kafkactl/auth.py` (cookie extraction function) - Modify: `pyproject.toml` (add browser-cookie3>=0.20.0 dependency) - New test: `tests/test_auth.py` (mocked cookie store tests) **Key Findings:** - browser-cookie3 library (v0.20.1) is stable with ~27k weekly downloads - Supports Chrome, Firefox, Safari (macOS only) - matches requirements - macOS keychain access may prompt for password - needs graceful handling - Library API is simple: `browser_cookie3.chrome(domain_name='...')` **Complexity:** Low **Ready for Implementation:** Yes See full triage report at: `/tmp/triage-KAFKA-1.md`
