Generate per-asset visual specifications and AI generation prompts from GDDs, level docs, or character profiles. Produces structured spec files and updates the master asset manifest. Run after art bible and GDD/level design are approved, before production begins.
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
If no argument is provided, check whether `design/assets/asset-manifest.md` exists: - If it exists: read it, find the first context (system/level/character) with any asset at status "Needed" but no spec file written yet, and use `question`: - Prompt: "The next unspecced context is **[target]**. Generate asset specs for it?" - Options: `[A] Yes — spec [target]` / `[B] Pick a different target` / `[C] Stop here` - If no manifest: fail with: > "Usage: `/asset-spec system:<name>` — e.g., `/asset-spec system:tower-defense` > Or: `/asset-spec level:iron-gate-fortress` / `/asset-spec character:frost-warden` > Run after your art bible and GDDs are approved." --- ## Phase 0: Parse Arguments Extract: - **Target type**: `system`, `level`, or `character` - **Target name**: the name after the colon (normalize to kebab-case) - **Review mode**: `--review [full|lean|solo]` if present **Mode behavior:** - `full` (default): spawn both `art-director` and `technical-artist` in parallel - `lean`: spawn `art-director` only — faster, skips technical constraint pass …

How to install
mdr add striderza/opencodegamestudios/asset-spec@sha256:80ad1243ccb1ca29The line at the top of this page pins the label git:20260622.695134d, 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.
