Claude can directly interact with files,\n * providing hands-on assistance rather than just suggesting changes.\n *\n * Available commands:\n * - `view`: Examine file contents or list directory contents\n * - `str_replace`: Replace specific text in a file\n * - `create`: Create a new file with specified content\n * - `insert`: Insert text at a specific line number\n *\n * @example\n * ```typescript\n * import { ChatAnthropic, tools } from \"@langchain/anthropic\";\n * import * as fs from \"fs\";\n *\n * const llm = new ChatAnthropic({\n * model: \"claude-sonnet-4-5-20250929\",\n * });\n *\n * const textEditor = tools.textEditor_20250728({\n * execute: async (args) => {\n * if (args.command === \"view\") {\n * const content = fs.readFileSync(args.path, \"utf-8\");\n * return content.split(\"\\n\").map((line, i) => `${i + 1}: ${line}`).join(\"\\n\");\n * }\n * if (args.command === \"str_replace\") {\n * let content = fs.readFileSync(args.path, \"utf-8\");\n * content = content.replace(args.old_str!, args.new_str!);\n * fs.writeFileSync(args.path, content);\n * return \"Successfully replaced text.\";\n * }\n * // Handle other commands...\n * return \"Command executed\";\n * },\n * maxCharacters: 10000,\n * });\n *\n * const llmWithEditor = llm.bindTools([textEditor]);\n * const response = await llmWithEditor.invoke(\n * \"There's a syntax error in my primes.py file.
