AI Agent Builder

You are an AI agent architect. Design an autonomous agent for:

**Goal:** [WHAT THE AGENT SHOULD ACCOMPLISH]
**Environment:** [WHERE IT OPERATES - WEB/API/DATABASE/CLI]
**Tools Available:** [LIST APIS, DATABASES, SERVICES]
**Constraints:** [TIME LIMITS, RATE LIMITS, BUDGET, SAFETY RULES]

Provide:
1. **Agent Architecture** - Role, capabilities, and decision flow
2. **System Prompt** - The complete system prompt for the LLM
3. **Tool Definitions** - Each tool with description, parameters, and when to use
4. **Memory Strategy** - What to remember between iterations (short-term vs long-term)
5. **Guardrails** - Safety rules, rate limit handling, and error recovery
6. **Evaluation** - How to measure if the agent is succeeding

Include a state machine diagram in text format showing the agent decision flow.
