Agent Architecture Spec Prompt
Turns a fuzzy agent idea into a reviewable five-layer architecture spec.
/ quick answer
Run before building any agent. Feed the output to your team (or your coding agent) as the implementation brief. Turns a fuzzy agent idea into a reviewable five-layer architecture spec.
You are an AI agent architect. I will describe a job I want an agent to do. Return a specification with exactly these sections:
1. JOB CONTRACT — input, output, success criteria, hard limits.
2. LOOP — ReAct, plan-and-execute or hybrid, with justification and a max step count.
3. TOOLS — table of tool name, purpose, read/write, approval requirement.
4. MEMORY — what must persist, where it lives, retention and retrieval strategy.
5. POLICY — forbidden actions, spend ceiling, escalation triggers, kill switch.
6. FAILURE MODES — top 5 ways this agent fails and the mitigation for each.
7. EVAL SET — 10 concrete test cases with expected outcomes.
Be specific and opinionated. Flag anything that should not be an agent at all.

The vocabulary this page depends on.
- →Agent Architecture
Agent architecture is the structural blueprint of an AI agent: the model, the planning loop, the tools, the memory layer and the guardrails that decide how it acts.
- →Agent Planning (ReAct, Plan-and-Execute)
Agent planning is how an AI agent decides its next step — reactively step-by-step (ReAct) or by drafting a full plan up front (plan-and-execute).
- →Multi-Agent System
A multi-agent system splits a job across several specialised AI agents that coordinate through a shared plan, message bus or orchestrator.
- →Agent Handoff
Agent handoff is the controlled transfer of a task — with its context — from one agent to another agent or to a human.

- →Cut Agent Costs by 60% Without Losing Quality
A measurable cost-reduction pass for any agent already in production.
- →AI Agent + Web3 Execution
Give an AI agent on-chain capability safely: read freely, propose openly, and sign only inside hard-coded limits.

Comparisons & alternatives
Pick between the options.
- →Single Agent vs Multi-Agent System
One well-equipped agent beats a crowd for most jobs; multi-agent wins on genuinely separable, parallel work.
- →AI Agent vs Trading Bot
A trading bot executes fixed rules deterministically; an AI agent interprets context and decides which steps to take — powerful for research, risky for execution.
