blue-build — Architecture & Stack for Base Builders

Produces a complete technical blueprint for a Base project: recommended stack, folder structure, key integrations, file-by-file breakdown, and test plan. Powered by Blue Agent via x402.

Trigger Conditions

Activate on:

• "Help me architect this on Base"
• "What stack should I use for X"
• "Blue build: "
• "Give me the technical plan / folder structure"
• Any request for technical architecture of a Base project

Output Structure

1. Stack — frontend, backend, smart contracts, infra (specific libs + versions)
2. Folder structure — full directory tree with file-level annotations
3. Key integrations — Base RPC, Coinbase Wallet SDK, x402, Uniswap v4, etc.
4. Core files — what each critical file does and rough implementation notes
5. Test plan — unit, integration, and onchain test strategy
6. Deployment — Vercel / Railway / Cloudflare + contract deploy flow

Key Rules

• Stack must be Base-native: Wagmi/Viem over Ethers, Base RPC endpoints, Base-deployed contracts
• No Ethereum mainnet assumptions — flag if a dependency isn't available on Base
• Folder structure must be production-ready, not tutorial-level
• Include .env.example variables list
• Test plan must cover at minimum: happy path, edge cases, onchain fork tests

Integration

This is step 2 of the founder workflow:

• Before: blue-idea — validate the concept ($0.05)
• After: blue-audit — security review ($1.00) → blue-ship — deploy checklist ($0.10)
