Proposal: Provide official llms.txt / prompts for LLM-assisted Firebase development

[fumito-ito]

Hi Firebase team,

I’d like to propose that Firebase officially provides LLM-friendly development prompts (such as in a llms.txt format), similar to what Supabase and a few other platforms have started doing.

Background

As AI-assisted coding (via ChatGPT, Claude, Gemini, etc.) becomes more common in real-world development workflows, developers are increasingly relying on structured prompts to:

• Scaffold Firebase projects using best practices
• Set up Firestore security rules correctly
• Write serverless Cloud Functions safely
• Implement Firebase Auth flows without breaking SSR
• Understand Firebase Emulator Suite usage
• Generate test cases, docs, and reviews automatically

Platforms like Supabase are now shipping official AI prompt guidelines that significantly reduce hallucinations, deprecated API usage, and misuse of auth/session flows. These prompts also act as live, executable documentation for LLMs.

Proposal

It would be extremely helpful if Firebase provided:

• A well-documented llms.txt file in the project root or docs
• A section in the Firebase docs for “AI/LLM-assisted development” use cases
• Official prompts for common use cases (Auth, Firestore, Cloud Functions, Emulator Suite, etc.)
• Clear examples of anti-patterns that LLMs should avoid generating

Benefits

• Improved developer experience for those using LLMs daily
• Reduced LLM-generated bugs related to outdated patterns or security holes
• Lower support load caused by AI-generated misuse
• Sets a standard for other cloud platforms to follow

I’d love to hear what the team thinks about this idea.

Thanks for considering!

Great idea! Thanks for the suggestion, @fumito-ito.

No plans yet, but I'll see if we can get this on our roadmap.
