Lead several agents building one Mirage world at the same time, one module each - the coordination contract (site plan as single source of truth, file ownership, anchors, append-only NOTES.md requests, merge order, conflict rules), how to launch workers in Claude Code (background sub-agents), Codex or Cursor, and how to integrate and verify. Use when a Mirage world has three or more modules to write, or the user says "build in parallel", "use sub-agents", "split the world", "fan out…
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
# Parallel build (lead)
The lead plans, launches, integrates and verifies; workers each write one module (mirage-module). It works
because nobody needs anybody else's code: positions come from `plan.js`, connections are anchors, and talk goes
through NOTES.md.
## 0. Before launching (lead)
- `BRIEF.md` with one module brief per module (mirage-brief-to-plan), `plan.js` complete for this round.
- Anchor contract fixed in the briefs: every key, who offers it, what `pos` is exactly, who consumes it.
- Lead files exist: `main.js`, `modules/index.js` listing every module, a stub `modules/<name>.js` per module
(`export default { name: '<name>', build() {} }`), `modules/materials.js`, NOTES.md with a `## <name>` header
per module, `scenarios/playtest.json`. `npx vite build && npm run playtest` passes on the stubs.
## 1. The contract (paste into every worker prompt: `references/worker-prompt.md`)
| rule | |
|---|---|
| ownership | a worker writes only `modules/<name>.js`, `scenarios/<name>.json`, its `## <name>` NOTES section; it may add module-only files `modules/<name>-*.js`. Everything else is read-only. |

How to install
mdr add paraldameta/mirage-engine/mirage-parallel-build@sha256:71acff317898517cThe 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.
