Context

AI coding agents (OpenCode, Codex, Cursor, Claude Code) produce inconsistent results without structured specifications. Teams lack a repeatable methodology for breaking down work into AI-executable units.

Approach

Created a 7-stage pipeline where each stage has a defined role, rules, explicit handoff criteria, and output template:

1. Idea — high-level concept

2. Briefing — context and constraints

3. PRD — product requirements

4. Architecture — system design

5. UX/UI — interface design

6. Tasks — granular breakdown

7. Prompts — AI-executable units

Designed for tool-agnostic use across any coding agent platform.

Outcome

  • Released as MIT-licensed open-source methodology
  • Provides a repeatable framework that reduces ambiguity in AI-assisted development
  • Used across multiple projects to produce consistent, production-quality code from AI agents
