mvp-plan

<!-- From the AI Product Development Toolkit (https://github.com/TechNomadCode/AI-Product-Development-Toolkit). Paste its skills install line again to update. --> This skill has two prompts in its folder. Unless the owner's message makes it clear, ask which one they need: - `mvp-plan.md`: a full development plan, with scope, tech stack, phases, testing and success metrics. - `mvp-plan-lean.md`: a short build spec for a fast first version, with purpose, user, features and tech choices. If a file is missing, tell the owner to install the skills again. Then run the prompt: - Read it in full and follow it exactly, as if the owner had pasted it. - Fill its placeholders from the owner: use what's in their message or the files they point to, and ask for the rest. Don't guess. - When the owner approves the draft, offer to save it as a Markdown file.
