img2mo-std · 2D Animation Baseline Standardizer

Audits and rescales a 2D character/prop baseline image with transparent action margin before motion generation.

Image & VideoIntermediate★ 208⑂ 7AI score 8/10Last updated: Jul 2, 2026

What it does

  • Triggered by /img2mo-std xxx.png, it audits your baseline frame and regenerates a standardized version.
  • Audit rules: subject longer than ~300–400px, subject touching the canvas edge, missing transparent room for limbs/weapons/capes/tails, opaque white background, oversized canvas, or prior frames showing clipping and scale popping.
  • Runs the repo tool scripts/standardize_baseline.py to emit sample/<stem>-standard.png, then reads the JSON report (needs_standardization, subject_longest_side, edge_clearance_ratio, warnings) to decide pass/fail.
  • Locks in a workflow rule: all later walk/attack/idle sprite generation must start from the standardized image.

Who it's for

  • Anyone generating 2D game sprites or character motion sheets with AI.
  • Artists hitting clipped limbs or inconsistent character scale across frames.
  • Indie devs using the 2dimg2motion pipeline.

Examples

  1. /img2mo-std s7 — resolves sample/s7.png and writes sample/s7-standard.png.
  2. Need more swing room: python scripts/standardize_baseline.py sample/s7.png --subject-max 320 --margin-ratio 0.85.
  3. Dry run: add --check-only to get the audit report without modifying the image.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/img2mo-std folder from the GitHub repo WU-HAOTIAN34/2dimg2motion into my ~/.claude/skills/img2mo-std/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/WU-HAOTIAN34/2dimg2motion.git && mkdir -p ~/.claude/skills && cp -r 2dimg2motion/skills/img2mo-std ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal in your projects folder.
  2. Clone the repo: git clone https://github.com/WU-HAOTIAN34/2dimg2motion.git
  3. Install the skill: mkdir -p ~/.claude/skills && cp -r 2dimg2motion/skills/img2mo-std ~/.claude/skills/
  4. Install Python 3 plus the image libraries the repo needs (e.g. Pillow — check its requirements file).
  5. Run cd 2dimg2motion and start Claude Code from the repo root, since the script path is relative.
  6. Test it with /img2mo-std sample/s7.png and check the JSON report output.
