@claude-code-kit/tools

Built-in tool collection for the claude-code-kit agent framework.

This package has two layers:

• builtinTools: 10 ready-to-use tools that form the default stable surface in v0.3.x
• Advanced factories: opt-in orchestration and integration helpers that are still evolving during 0.x

Ready-to-use built-ins

| Tool | Description | Read-only | |------|-------------|-----------| | Bash | Execute shell commands | No | | Read | Read file contents with line numbers | Yes | | Edit | Edit files via unique string replacement | No | | Write | Write/create files with auto-mkdir | No | | Glob | Find files by glob pattern | Yes | | Grep | Search file contents with regex | Yes | | WebFetch | Make HTTP requests | Yes (GET) | | WebSearch | Search the public web with domain allow/block filters | Yes | | EnterWorktree | Create and enter a git worktree | No | | ExitWorktree | Clean up and exit a git worktree | No |

Advanced factories

| Export | Produces | Status | Description | |--------|----------|--------|-------------| | createLspTool | LSP | Experimental | Language Server Protocol queries against a caller-provided transport | | createSubagentTool | Agent | Experimental | Delegates isolated work to a child agent | | createTaskTool | TaskCreate / TaskUpdate / TaskGet / TaskList | Experimental | In-memory task orchestration toolset | | notebookEditTool | NotebookEdit | Experimental | Edit Jupyter notebook cells |

Usage

import { Agent, AnthropicProvider } from "@claude-code-kit/agent";
import { builtinTools } from "@claude-code-kit/tools";

const agent = new Agent({
  provider: new AnthropicProvider({ apiKey: "..." }),
  model: "claude-sonnet-4-20250514",
  tools: builtinTools,
});

builtinTools includes only the ready-to-use core toolset. Advanced factories are opt-in and should be added explicitly when you want those workflows.

Or import individual tools:

import { bashTool, readTool, editTool } from "@claude-code-kit/tools";
