PR Review Summary

Prek Checks

Linting and formatting passed. Fixed missing -> None return type annotations in tests/test_help_banner.py (auto-committed).

Code Review

SMALL PR — focused correctness check.

The implementation is clean and correct:

• main.py:36-37 — checks sys.argv[1:] before parse_args() so the banner is printed before argparse intercepts and exits. No double-banner risk since argparse exits via sys.exit(0) when --help is passed, so line 40 is never reached.
• print_codeflash_banner() at line 40 handles the normal (non-help, non-auth) flow, unchanged from before.

One minor observation: codeflash init --help (and other subcommands) will also trigger the banner since --help is in sys.argv[1:] regardless of position. This matches the stated test plan, so it appears intentional.

No bugs, security issues, or breaking changes found.

Duplicate Detection

No duplicates detected. print_codeflash_banner() is already defined and reused.

Test Coverage

Tests cover both --help and -h flags. The subprocess-based approach correctly verifies the full CLI behavior end-to-end.

Auto-fixed: Added -> None return type annotations to both test functions in tests/test_help_banner.py (commit 8e2bab2e).
