Brainstorm-to-Build Skill

Converts a project idea into 3 sequential prompt files that progressively build the project.

Steps

Understand the idea — Extract: what it is, tech stack (or infer one), key features, target user.
Plan the 3 stages — Identify MVP scope, highest-priority/standout features, and remaining polish items.
Generate 3 prompt files — Write each to /mnt/user-data/outputs/<project-slug>/.

Goal: Working skeleton. Claude reading this should be able to build a runnable project.

Include:

Project summary (1–2 lines)
High-level architecture (layers, services, data flow)
Tech stack with versions if relevant
File/folder structure
Core data models / DB schema
MVP feature list (minimum to "work")
Prompt instruction: "Build this project end-to-end as described. Prioritize correctness over polish. Deliver a working MVP."

Goal: Elevate the most impactful or visually standout features.

Include:

Reference to prompt-1 output ("Assume the MVP from Stage 1 is built")
List of high-priority features to optimize (pick top 2–4)
For each: what "good" looks like, edge cases, UX/perf notes
Any standout UI interaction or complex business logic to nail
Prompt instruction: "Optimize only the listed features. Don't refactor unrelated code."

Goal: Ship-ready quality on everything remaining.

Include:

Reference to prompt-1 and prompt-2 outputs
Remaining feature checklist (everything not in Stage 2)
Non-functional concerns: error handling, loading states, empty states, responsiveness, accessibility, security basics, env config
Code quality: remove dead code, consistent naming, add comments where needed
Prompt instruction: "Do a final pass. Fix all rough edges. The output should be production-ready."

Be decisive. Pick a reasonable tech stack if the user hasn't. State assumptions inline rather than asking.
