Practical templates for turning an idea into a clear product scope, design brief, architecture, specifications, and AI-ready implementation plan.
“What do we build for, if not to lessen each other’s hardship?”
idea/ Problem and opportunity framing
validation/ Assumptions and validation plans
product/ PRD, MVP scope, stories, acceptance criteria
design/ Design briefs and UX decisions
engineering/ Architecture, ADRs, and implementation plans
agents/ Context and working agreements for coding agents
- Turning an early idea into an MVP
- Preparing a project before code generation
- Writing implementation-ready feature specs
- Handing work to an AI coding agent
- Recording decisions that should survive chat history
Keep documents short, decision-oriented, and current. Delete stale assumptions instead of accumulating process for its own sake.
Fonij may generate or update these artifacts automatically, but the files remain understandable without the CLI.
