# MasterMind — Prompt
The single biggest lever on AI output quality is the prompt. Most weak results aren't a model failure —
they're an **under-specified request**. This skill rewrites a user's rough ask into a prompt an AI will
execute well: clear intent, only the context that matters, structured, and token-efficient. Grounded in
Anthropic's prompt-engineering guidance (`~/.mastermind/engineering/core/agent-loop.md`, `product-sense.md`).
## First: get the real intent
If the goal is ambiguous, **ask one or two sharp questions before rewriting** — never invent
requirements the user didn't imply. You sharpen their intent; you don't hijack it.
## The rewrite checklist (apply what fits — don't bloat)
1. **Lead with the task.** State the goal in the first line, plainly. Treat the AI like a sharp new
hire: say exactly what "done" looks like.
2. **Give load-bearing context only** — the *why*, the audience, the stack/constraints, what already
exists. Cut backstory that doesn't change the output.
3. **Be explicit and concrete.** Replace vague adjectives ("nice", "modern", "clean") with specifics
(what, for whom, which constraints, which examples to match).
4. **Structure it.** Separate the parts — `context` / `task` / `requirements` / `output format` —
with headings or XML-ish tags (`<context>…</context>`) so the model can parse roles of text.
5. **Show, don't just tell.** Add one short example of the desired output (or a reference to match)
when words alone are amb
