Create a project from scratch

This path starts from an idea that has not been coded yet. The priority is not to generate code quickly, but to produce a base that Codex can use.

What the user does

• Create a ChatGPT or Claude project dedicated to the product.
• Describe the intent without freezing the solution too early.
• Ask the AI to challenge the idea, competitors, open-source building blocks and risks.
• Validate V0, exclusions and critical business rules.
• Produce a Codex Project Pack.

Recommended steps

1. Create a dedicated discovery space.
2. Describe product intent.
3. Ask for analysis of blind spots, risks, competitors, alternatives and open-source building blocks.
4. Formalize Product Discovery.
5. Identify domain expertise areas.
6. Generate the Codex Project Pack.
7. Create the GitHub repository.
8. Install the SR Method from the official repository.
9. Ask Codex to restate its understanding and propose first lots.
10. Validate the first lot before any code.

Prompt for additional documents

Which documents should we produce before handing this project to Codex?

I want a folder usable by a Codex developer: brief, PRD, functional specs, technical architecture, data model, API, UX, security, test strategy, roadmap, initial lots, bootstrap prompt, domain map and domain skills plan.

Also propose additional documents required by the domain: regulation, security, RAG, runtime agents, integrations, existing migration, mobile/offline or specialized UX.

Condition before code

Codex should start development only when:

• V0 scope is clear;
• exclusions are explicit;
• critical business rules are documented;
• first lots are validated;
• the user has validated the lot to execute.
