How to draw hands in drawn-by-code, in any style. Use it before drawing, redrawing or reviewing any hand, and whenever a character holds, grips, carries, throws, touches or points at something, or the user complains about a hand. Covers the reference-first workflow, handedness, the grips and what is visible from each side, proportions, one-skin drawing, and the hand check sheet that must pass before any render.

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

# Hands

Hands are where the viewer catches a fake first, and where this repo has failed most often. In
physics-history the hands took rounds 13 to 16b, many of them making things worse, for
three reasons:
- the grip was guessed instead of copied;
- the hand was mirrored (a left hand's geometry on a right arm);
- images were sent without being looked at.

Follow this page every time a hand is on screen.

## The workflow (in this order, every time)

1. **Reference first.** Before drawing any grip, find or ask for a reference of that grip
   seen from the camera's side: a drawing or a photo, or the user's own hand. Write in the
   code comment which reference it follows. Never invent a grip from memory. The user's
   references are the best ones; ask for one as soon as a grip is new.
2. **Decide what is visible from the camera.** Grips hide a lot: a fist round a bar seen
   from the fingers' side shows no thumb at all. Draw only what the reference shows. A thumb
   that "should be there" drawn where it would be hidden is the typical mistake.
3. **Check handedness against a real hand in the same pose, forearm included.** For a right

How to install

The exact contents, by fingerprint
mdr add illodev/drawn-by-code/hands@sha256:1a8f3d0368210d44

The line at the top of this page pins the label git:20260925.a9e0822, 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.
