Built-in Tools

Built-in tools are not enabled by default. Use createClaudeCodeTools() when your application intentionally wants Claude Code-style workspace access.

import {
  createAgent,
  createClaudeCodeTools,
} from "@npm-while1/claude-agent-sdk";

const agent = createAgent({
  apiKey: process.env.DEEPSEEK_API_KEY,
  baseURL: "https://api.deepseek.com/anthropic",
  model: "deepseek-v4-flash",
  tools: createClaudeCodeTools({
    cwd: process.cwd(),
    allowedDirectories: [process.cwd()],
    bashTimeoutMs: 30_000,
  }),
});
