claude-agent-sdk

claude-agent-sdk is a skill for Claude Code from tdimino/claude-code-minoan. It costs 64 tokens per session (1,859 once invoked), scanned A, original, MIT.

A software kit for building AI agents with Anthropic's Claude models. It supports one-off tasks, ongoing conversations, custom tools, connections to MCP servers, permission controls, hooks, subagents, and browser automation.

In plain words
What is it for?
Use it to create agents and configure how they act, add tools or browser control, connect external services, and automate coding tasks in Python or TypeScript.
Why use it?
It provides the building blocks for agents that can read files, run commands, search the web, edit code, and check their work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

claude-agent-sdk scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (templates/agent-with-tracking-python.py, templates/continuous-chat-python.py, templates/custom-tool-python.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Claude Agent SDK Overview

The Claude Agent SDK gives agents the same tools that power Claude Code: file operations, bash commands, web search, and more. Build autonomous agents that read files, run commands, search the web, edit code, and verify their work.

Two Ways to Query

Function Session Best For
query() New each time One-off tasks, automation
ClaudeSDKClient Continuous Conversations, follow-ups, hooks

Key Difference: query() is simpler but doesn't support hooks, interrupts, or custom tools. Use ClaudeSDKClient for advanced features.

Agent Loop Pattern

Agents operate in a feedback loop:

gather context → take action → verify work → repeat

Installation

Python:

uv add claude-agent-sdk

TypeScript:

npm install @anthropic-ai/claude-agent-sdk

Requirements:

  • Claude Code CLI installed (npm install -g @anthropic-ai/claude-code)
  • ANTHROPIC_API_KEY environment variable set

Quick Start

import asyncio
from claude_agent_sdk import query, ClaudeAgentOptions

async def main():
    async for message in query(
        prompt="Find and fix bugs in auth.py",
        options=ClaudeAgentOptions(allowed_tools=["Read", "Edit", "Bash"])
    ):
        print(message)

asyncio.run(main())

What would you like to do?

  1. Create a new agent - Build an agent from scratch
  2. Add custom tools - Create tools with @tool decorator or MCP servers
  3. Add hooks - Intercept tool calls for logging, validation, or modification
  4. Configure permissions - Control what tools can do
  5. Create subagents - Define specialized agents for parallel work
  6. Control browsers - Chrome extension, dev-browser skill
  7. Get API reference - Python or TypeScript SDK details

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
