Turn a one-paragraph idea into a Mirage world's direction before any building ("先定方向再建设") - a brief (idea, mood, references, scale, target), a site plan plan.js (bounds, regions, footprints, paths, points, viewpoints, spawn, place, sun and time), a module list with build order, a brief per module, and the project scaffold. Use when starting a new Mirage world, when the user says "I want a scene of ...", "plan the world", "site plan", "layout", "brief", or when a world has no plan.js yet.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Brief → plan Direction first, building second. Nothing is modelled until the brief and the plan exist, because the plan is what lets several agents build at once without asking each other where things are. ## 1. Brief (5 minutes) → `BRIEF.md` Copy `references/brief-template.md`. Fill every field from the user's paragraph; where it says nothing, choose and write the choice down (do not ask unless the choice changes the whole world). One line each: | field | answers | becomes | |---|---|---| | idea | what the place is, what you do there | regions, the walk route, the interactable | | mood | time of day, weather, palette, sound | `render.time`, fog, materials' tints, audio loops | | references | 2–4 *kinds* of place or picture (no copyrighted designs, no real named sites) | proportions, materials | | scale | metres across, how long a walk takes | `bounds`, path lengths (walking speed 1.5 m/s, run 4.2) | | target | walk / game / stills; device; size budget | modes, `@mirage/game` or not, budgets | ## 2. Plan → `plan.js` Start from `references/plan-template.js`. Work on paper first: draw the bounds, then the regions, then the …

How to install
mdr add paraldameta/mirage-engine/mirage-brief-to-plan@sha256:06e8e22e869f5d79The line at the top of this page pins the label git:20261025.cd36420, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
