📝 WalkthroughWalkthroughA new authentication manager module is introduced with a static class providing two entry points: one for retrieving provider API credentials from environment variables and another for session token validation. Changes

3-12: Consider integration strategy with existing backends.The relevant code snippets show that
oai.py,gemini.py, andclaude_computer_use_tool.pyalready read their respective API keys directly viaos.getenv(). This new manager duplicates that pattern but won't be used by existing code paths until those backends are refactored.Consider documenting the migration plan or updating at least one backend to use
AuthProviderManager.get_credentials()as a reference implementation. Otherwise, callers may be confused about which approach to use.🤖 Prompt for AI Agents

function signature to include a return type hint (-> Optional[str]), add a
Google-style docstring describing parameters and return value, replace the
print(f"Retrieving credentials for provider: {provider}") with
logging.debug(...) and ensure typing.Optional is imported (or referenced) and
logging is configured/imported so get_credentials(provider: str) returns
Optional[str] and logs at debug level.

Missing docstring, return type hint, and inappropriate print() statement.
Per coding guidelines, new functions require Google-style docstrings. Additionally:
- Missing return type hint (
-> Optional[str]) print()should be replaced with proper logging (e.g.,logging.debug()) to avoid polluting stdout in production and to respect log level configuration
Proposed fix

+logger = logging.getLogger(__name__)

There was a problem hiding this comment.
Security risk: stub always returns True; also missing docstring and return type.
This method unconditionally returns True, which is dangerous if called in production—it would accept any token as valid. Consider either:
- Raising
NotImplementedErrorto prevent accidental use until implemented - Adding a prominent warning/TODO and ensuring this isn't wired into any auth flow yet
Also missing Google-style docstring and return type hint (-> bool).
Proposed fix (raise until implemented)
