Implementation Reference

• mcp_hitchcode/server.py:317-340 (handler)

  The core handler function for the 'apply_prompt_unit_tests' tool. It renders a prompt template named 'test' using the provided code_to_test, specific_instructions, and version, then returns the result as TextContent.

  async def apply_prompt_unit_tests(
      code_to_test: str,
      specific_instructions: str = "",
      version: str = "latest",
  ) -> list[types.TextContent]:
      """
      Provides a prompt for generating unit tests for code.
  
      Args:
          code_to_test: The code that needs unit tests.
          specific_instructions: Optional specific instructions to include in the prompt.
          version: The version of the prompt template to use. Defaults to "latest".
  
      Returns:
          A list containing a TextContent object with the prompt.
      """
      # Render the prompt template with the code to test and specific instructions
      response_text = render_prompt_template(
          "test",
          version_str=version,
          code_to_test=code_to_test,

• mcp_hitchcode/server.py:725-746 (schema)

  The input schema definition for the tool, specifying required 'code_to_test' parameter and optional 'specific_instructions' and 'version'.

• mcp_hitchcode/server.py:510-524 (registration)

  The dispatch logic in the call_tool handler that routes requests for 'apply_prompt_unit_tests' to the corresponding function, including input validation.

          return [

                  text="Error: Missing required argument 'code_to_test'",
              )
          ]
