Free, copy-paste prompts and coding-assistant rules for building software with AI.
Everything here is a plain Markdown file. You don't need to install anything or clone this repository.
- Pick a prompt from the table below and open its file.
- Copy the contents and fill in the bracketed placeholders with your project details.
- Paste it into your AI chat, answer its questions, and review the draft it produces.
New here? Start with the PRD prompt (guide). It turns a rough app idea into a clear requirements document.
Most prompts ask the AI to write a document straight away, so it fills the gaps with guesses. These prompts make it interview you first:
- It asks before it writes. The AI asks a few targeted questions at a time about your idea, users, and goals.
- You confirm what it understood. It states its assumptions and checks with you before moving to a new section.
- It only drafts once you agree. The final document is built from your answers, not from guesses.
- Each step feeds the next. Later prompts use your PRD and earlier outputs, so the plan stays consistent.
Listed in the order you would normally use them. You can start at any step; each folder's guide explains what to bring.
| Step | Prompt | What you get |
|---|---|---|
| 1. Research users | User research questionnaire | A questionnaire, then a research summary for your PRD |
| 2. Define the product | PRD generation | Goals, users, requirements, and constraints |
| 3. Map the experience | UX and user flow | User journeys and interface requirements |
| 4. Scope the first release | MVP concept | Core problem, hypothesis, and a short feature list |
| 5. Plan the build | MVP development plan or ultra-lean version | A detailed plan, or a smaller build spec |
| 6. Plan testing | Test plan | Test scope, cases, and acceptance criteria |
| 7. Design the UI | v0 design prompts | A ready-to-use prompt for v0.dev |
| Anytime | Session continuation | A handoff so you can continue in a fresh chat |

Rules and settings for Claude Code. Merge them into your own setup instead of replacing it.
| Config | What it does |
|---|---|
| Claude Opus 5.5 rules (latest) | A CLAUDE.md for clear scope, concise replies, and up-to-date docs lookups |
| Claude Opus 5 rules | The same idea, written for Opus 5 |
| Permission guardrails | An optional, strict settings.json that blocks risky commands. Read it before using it |

- AI output is a draft. Review requirements, plans, and code before relying on them.
- Don't paste private information your AI tool doesn't need.
