Greptile Overview

Greptile Summary

This PR refactors authentication header handling in executor handlers by replacing hardcoded Content-Type headers with the centralized buildAuthHeaders() utility function.

• Updated evaluator-handler.ts and router-handler.ts to use buildAuthHeaders() instead of manually setting headers
• The buildAuthHeaders() utility provides both Content-Type and Authorization headers with internal tokens when running server-side
• Added mock implementations for the http utils in testing package to support unit tests
• This change ensures consistent authentication across all provider API calls and aligns with the pattern already used in agent-handler.ts and workflow-handler.ts

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward refactoring that improves consistency by using an established utility function. The buildAuthHeaders() utility already exists and is used in other handlers (agent, workflow). The mock implementation properly mirrors the actual implementation behavior. No breaking changes or risky logic alterations.
• No files require special attention
