Power Agent Creator
Overview
This skill provides everything needed to create powerful AI agents comparable to Claude Code. It includes:
Battle-tested System Prompt - A masterpiece prompt refined through millions of dollars of evaluation
Production-ready Tools - Comprehensive toolset for file ops, search, execution, and task management
The Agent Loop - The same simple pattern used by the most powerful agents
Core Philosophy
"The main agent is just a loop. The session memory is just a list of messages. It is enough to build the most powerful agent in the world. PERIOD!"
CRITICAL: Do NOT modify the system prompts or tool descriptions. They are masterpieces refined through extensive evaluation.
The Customization Secret
To create ANY kind of agent, you only need to add ONE HumanMessage after the SystemMessage:
from langchain_core.messages import SystemMessage, HumanMessage
from prompts import coding_agent_prompt
messages = [
SystemMessage(content=coding_agent_prompt()),
HumanMessage(content="""You are now specialized as a [ROLE].
Your additional capabilities:
- [CAPABILITY 1]
- [CAPABILITY 2]
Your constraints:
- [CONSTRAINT 1]
- [CONSTRAINT 2]
Focus on: [SPECIFIC DOMAIN]"""),

Structured messaging protocols for agent team communication including message type selection, plan approval, shutdown procedures, and anti-patterns to avoid. Use this skill when establishing communication norms for a newly spawned team, when deciding whether to send a direct message or a broadcast, when a team-lead needs to review and approve an implementer's plan before work begins, when orchestrating a graceful team shutdown after all tasks are complete, or when debugging why teammates are not
