🧹 [Code Health] Refactor handle_json_rpc_message to reduce deep nesting#18
Conversation
Extracted deep nesting in the `handle_json_rpc_message` method by pulling out the logic for `initialize`, `tools/list`, and `tools/call` into dedicated helper functions: `handle_initialize`, `handle_tools_list`, and `handle_tools_call_request`. This change preserves all previous functionality and greatly reduces cognitive load. Co-authored-by: google-labs-jules[bot] <161369871+google-labs-jules[bot]@users.noreply.github.com>

🎯 What: The code health issue addressed was the deeply nested
matchblock logic inhandle_json_rpc_messagefound incrates/poke-around/src/mcp.rs. The logic to handle multiple MCP methods (initialize,tools/list,tools/call) was previously implemented entirely inline, making the function overly complex.💡 Why: Extracting the logic into dedicated helper functions (
handle_initialize,handle_tools_list,handle_tools_call_request) reduces cognitive load and improves testability by isolating responsibilities. The main match block is now clean and easily legible.✅ Verification: I ran
cargo checkandcargo testfor the workspace. All modules compiled successfully and all test cases passed, ensuring that no prior logic or functionality was broken by the extraction. Code review also verified correctness and safety.✨ Result: Improved maintainability and reduced complexity for
handle_json_rpc_messagein the MCP server logic.PR created automatically by Jules for task 16878614178767090670 started by @undivisible
