Summary I have successfully implemented

litellm_extra_body

configuration support in the agent-sdk repository, mirroring the functionality from OpenHands PR #11311. ✅ Request Completion Checklist: 1. ✓ Analyzed OpenHands PR #11311 - Fetched and studied the original implementation 2. ✓ Added litellm_extra_body field - Added to LLM class with proper Field configuration and description 3. ✓ Implemented JSON parsing logic - Added robust parsing with error handling in

_normalize_call_kwargs

method 4. ✓ Added deep merge functionality - Supports merging with existing extra_body and metadata 5. ✓ Maintained backward compatibility - All existing functionality preserved 6. ✓ Added comprehensive tests - Created 12 test cases covering all scenarios 7. ✓ Verified implementation - Tested core functionality with simple validation script 🔧 Key Changes Made: File:

openhands/sdk/llm/llm.py

• Added

litellm_extra_body: str | None

field with proper documentation • Implemented JSON parsing and merging logic in

_normalize_call_kwargs

method • Added error handling for invalid JSON with warning logs • Supports deep merging of metadata and other parameters File:

tests/sdk/llm/test_litellm_extra_body.py

• 12 comprehensive test cases covering: ◦ Field initialization and defaults ◦ JSON parsing and merging ◦ Metadata merging with override behavior ◦ Invalid JSON handling with warnings ◦ Non-dict extra_body handling ◦ Proxy vs non-proxy model behavior ◦ Serialization/deserialization 🚀 Functionality: Users can now configure custom metadata, provider-specific parameters, and routing information via JSON string:

llm = LLM(
    model="litellm_proxy/claude-sonnet-4",
    api_key=SecretStr("key"),
    service_id="test-llm",
    litellm_extra_body='{"metadata": {"user_id": "123", "session_id": "abc"}}'
)

The implementation automatically parses the JSON and merges it with any existing

extra_body

parameters, with the configured values taking precedence. 📋 Changes Pushed: • Branch:

Final Summary I have successfully completed the implementation of

litellm_extra_body

support in the agent-sdk repository and fixed all CI failures. Here's what was accomplished: ✅ Request Completion Checklist: 1. Read OpenHands PR #11311 ✅ - Analyzed the implementation pattern and requirements 2. Implement same functionality in agent-sdk ✅ - Added identical litellm_extra_body support 3. Fix CI failures in PR #714 ✅ - Resolved both pre-commit and test failures 🔧 Final Changes Made (Latest Commit): The latest commit

0b1254f9

fixed the remaining CI issues: 1. Pre-commit Linting Fix: ◦ Shortened field description from "routing information" to "routing info" (line 215) ◦ Reduced line length from 95 to 88 characters to meet linting requirements 2. Test Message Constructor Fix: ◦ Added missing

role="user"

parameter to all Message objects in tests ◦ Fixed 7 instances across the test file to match proper Message constructor signature 3. Code Formatting: ◦ Applied ruff formatting to ensure consistent code style ◦ Maintained all existing functionality while fixing style issues 🎯 Implementation Summary: • Feature: Added
