Implementation Reference
- mcp_hitchcode/server.py:239-262 (handler)The core handler function for the 'apply_prompt_change' tool. It renders the 'change' prompt template using the provided change_request, optional specific_instructions, and version, then returns it as TextContent.async def apply_prompt_change( change_request: str, specific_instructions: str = "", version: str = "latest", ) -> list[types.TextContent]: """ Provides a prompt for systematically handling change requests.
