AI Summaryagent-builder enables developers to create production-ready AI agents with pai-agent-sdk and Pydantic AI, including tools configuration, session persistence, and hierarchical agent setups. Ideal for building autonomous applications, chatbots, and HITL workflows.
Install
Copy this and paste it into Claude Code, Cursor, or any AI assistant:
I want to install the "agent-builder" skill in my project. Please run this command in my terminal: # Install skill into the correct directory mkdir -p .claude/skills/pai-agent-sdk && curl --retry 3 --retry-delay 2 --retry-all-errors -o .claude/skills/pai-agent-sdk/SKILL.md "https://raw.githubusercontent.com/youware-labs/pai-agent-sdk/main/SKILL.md" Then restart Claude Code (or reload the window in Cursor) so the skill is picked up.
Description
Build AI agents using pai-agent-sdk with Pydantic AI. Covers agent creation via create_agent(), toolset configuration, session persistence with ResumableState, subagent hierarchies, and browser automation. Use when creating agent applications, configuring custom tools, managing multi-turn sessions, setting up hierarchical agents, or implementing HITL approval flows.
Creating Custom Tools
Inherit from BaseTool: `python from pai_agent_sdk.toolsets.core.base import BaseTool from pydantic_ai import RunContext from pai_agent_sdk.context import AgentContext class MyTool(BaseTool): name = "my_tool" description = "Does something useful" async def call(self, ctx: RunContext[AgentContext], arg: str) -> str: return f"Result: {arg}" ` Full guide: docs/toolset.md
See examples/browser_use.py for complete implementation
` Full example: examples/browser_use.py
Agent can read messages via bus tools
` Full guide: docs/message-bus.md
