Create or improve a 32×32 pixel-art persona face for the Frontier Faces demo (examples/04-frontier-faces/personas.mjs) — the animated agent avatars rendered by face-term.mjs / the browser <cotal-face> / the gallery. Use when the user asks to add a new persona/face/avatar, improve an existing one (hair, eyes, likeness, expression), make it "look more like" someone, or fix a face that "doesn't read". Drives the example's own tools (img2rows.mjs, render-png.mjs) and follows FACE-DESIGN.md; uses a…
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
# pixel-face — author & refine the Frontier Faces pixel art A persona face is pure data in **`examples/04-frontier-faces/personas.mjs`** (one entry per persona). The same data drives the terminal renderer (`face-term.mjs`), the browser element (`web/cotal-face.js`), and the PNG tool — so edit `personas.mjs` once and it's live everywhere. **Always work from `examples/04-frontier-faces/`.** ## Where things are - `personas.mjs` — the entries (rows, colors, glow, mouths, expr, eyes, lines). Single source of truth. - `FACE-DESIGN.md` — the full conventions (grid zones, color keys, eye recipe, visemes). **Read it first.** - `tools/img2rows.mjs` — rough a reference photo into a 32×32 `rows`+palette. - `tools/render-png.mjs` — render a 7-state contact sheet (PNG) for review. **This is the validator.** - `tools/face-template.mjs` — copy-me starter entry that encodes the conventions. - `gallery.html` (all personas, original-vs-pixel) and `preview.html?p=<key>` (one persona) — served via `python3 -m http.server` or `tools/serve-wall.mjs`; for visual QA. - `assets/<persona-key>.<ext>` — reference photos. **Gitignored / local-only — never commit them.** …

How to install
mdr add cotal-ai/cotal/pixel-face@sha256:82c3fe3f44e12967The line at the top of this page pins the label git:20260630.58d0aa6, 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.
