Implementation Reference
- claude-code-server/src/index.ts:560-570 (handler)The main handler function for the 'edit_code' tool. It destructures the input arguments (code and instructions), encodes the code to base64 using a helper, truncates if too long, constructs a specific prompt for Claude to edit the code, calls the shared runClaudeCommand helper to execute Claude CLI, and returns the generated output as text content.
case 'edit_code': { const { code, instructions } = args; logger.debug(`Processing edit_code request, code length: ${code.length}`); const encodedCode = encodeText(truncateIfNeeded(code)); logger.debug(`Code encoded to base64, length: ${encodedCode.length}`); const prompt = `You are super professional engineer. Please edit the following Base64 encoded code according to the instructions provided:\n\nCode:\n${encodedCode}\n\nInstructions:\n${instructions ?? 'No specific instructions provided.'}`; logger.debug('Calling Claude CLI with prompt'); const output = await runClaudeCommand(['--print'], prompt); logger.debug(`Received response from Claude, length: ${output.length}`); return { content: [{ type: 'text', text: output }] }; } - claude-code-server/src/index.ts:359-370 (registration)Registration of the 'edit_code' tool in the ListTools response, including its name, description, and input schema definition.
