I Ran Anatomy's /anatomy Skill on a 1.7B Local Model. The Kit Passed Every Check; the Figure Was 738 Bytes.

Description and use

The Anatomy kit functions correctly on a plain Linux box: examples rebuild deterministically, tests pass, geometry audit and headless‑Chrome checks succeed. The /anatomy skill runs but produces minimal SVG output with limited interactivity because the local 1.7B model is too weak to drive the full skill workflow.

Problem

Determine if the Anatomy skill and its underlying kit work correctly on a plain Linux box with a local 1.7B model, and assess how much of the output is driven by the skill versus the model.

Outcome

The Anatomy kit functions correctly on a plain Linux box: examples rebuild deterministically, tests pass, geometry audit and headless‑Chrome checks succeed. The /anatomy skill runs but produces minimal SVG output with limited interactivity because the local 1.7B model is too weak to drive the full skill workflow.

Workflow

• Install Node 22.20.0 and run npx skills add wheresryan22/anatomy -g -a opencode -y to install the skill.
• Verify installation path with opencode debug skill.
• Run kit examples via node examples/.../build.mjs and confirm byte‑identical output.
• Execute the test suite with npm test and note the five React‑related failures.
• Run geometry audit with node examples/arcade-cabinet/build.mjs --audit audit and confirm pass.
• Set CHROME_PATH and run headless‑Chrome checks with node scripts/capture.mjs and node scripts/lines.mjs.
• Run /anatomy prompts using opencode run --model ollama/qwen3:1.7b --command anatomy "prompt" < /dev/null and adjust provider timeout settings.
• Collect generated SVG files and inspect their content and location.

The README's quick start is one line: npx skills add wheresryan22/anatomy -g -a opencode -y
