Summary

  • Adds codeflash auth login CLI subcommand for standalone OAuth authentication
  • Prints the auth URL for the user to open, runs the full PKCE flow, and saves the API key
  • Skips OAuth if an existing API key is detected

Test plan

  • Unit tests for all auth_login() code paths (existing key, OSError, OAuth failure, success, Windows RC creation)
  • Argument parsing tests for auth login and bare auth
  • uv run prek passes on all changed files

Prek Checks

All checks pass (ruff check, ruff format, mypy).

Code Review

Bug: Two tests were failing — test_successful_oauth_saves_key and test_windows_creates_rc_file_if_missing both patched codeflash.cli_cmds.cmd_auth.get_shell_rc_path, but get_shell_rc_path is never imported in cmd_auth.py (it lives inside save_api_key_to_rc in shell_utils.py). This caused AttributeError at test setup, and test_windows_creates_rc_file_if_missing also asserted mock_rc_path.touch.assert_called_once() — behavior that only exists inside save_api_key_to_rc, not in auth_login() itself.

Fixed and pushed (commit 2857e847): removed the phantom patches, dropped the untestable .touch() assertion, and renamed test_windows_creates_rc_file_if_missing → test_windows_oauth_saves_key to reflect what it actually tests. All 7 tests now pass.

Minor observation (cmd_auth.py): auth_login uses click.echo for error/success messages while using console.print (Rich) for status messages. Mixed output libraries in the same function is inconsistent, but not a blocking issue.

save_api_key_to_rc failure path (cmd_auth.py:35-36): when save_api_key_to_rc returns a Failure, the error is echoed but the function still prints "Signed in successfully!" and sets CODEFLASH_API_KEY. The API key is usable in-process but won't persist across sessions. This could silently mislead users. Worth either early-returning or adjusting the success message to note that persistence failed.

Duplicate Detection

No duplicates detected. auth_login and auth_status are new entry points with no equivalent elsewhere.

Test Coverage

7 tests added covering all major code paths in auth_login and argument parsing. auth_status has no dedicated tests — low risk given its simplicity, but worth noting.

Optimize auth_login
7985f16 
The optimization removed redundant operations that duplicated logic already inside `save_api_key_to_rc`. Previously, `auth_login` called `get_shell_rc_path()` (which performs `Path.home()` filesystem operations) and conditionally invoked `shell_rc_path.touch()` on Windows, then passed the result to `save_api_key_to_rc`. The optimized version calls `save_api_key_to_rc(api_key)` directly, because that function already internally calls `get_shell_rc_path()` and safely handles file creation via context managers. Line profiler shows `get_shell_rc_path()` dropped from ~1 ms to negligible per-call overhead, and `shell_rc_path.touch()` overhead was eliminated entirely. Runtime improved from 19 ms to 1.13 ms (1582% speedup) with no regressions across all test scenarios.
