What it does
Vision Decompose is an agent skill from ReshefElisha/jarvis-onshape-mcp. Look at an engineering reference image (drawing, iso render, photo) and produce a structured feature decomposition BEFORE building anything in Onshape. Output is a feature tree the user can review and the build phase can execute against. Use this whenever the user gives you a reference image and asks you to model it. Skip if the user has already described the part in plain text.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Jarvis Onshape MCP — Claude Code plugin for driving real Onshape CAD. Vision-decomposition skill + truth-telling + parametric iteration + FeatureScript.
When your agent uses it
- Gives you a reference image and asks you to model it
Example prompts
- “/vision-decompose”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Overview scan. Look at the attached images for ~5 seconds. Write the
- Cache + count. For each reference image path, call
- Crop-and-describe each feature. For every feature you counted, use

What it can do on your machine
Read from SKILL.md and the folder at commit b0e7258. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Vision Decompose loads about 1.9k tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 853 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 853 words (~1,937 tokens).
“When the user shares an engineering reference image and asks you to build it, your first job is NOT to start create_document. It is to produce a rigorous, structured feature tree the user can sanity-check and the build phase can…”

What does Vision Decompose do?
Look at an engineering reference image (drawing, iso render, photo) and produce a structured feature decomposition BEFORE building anything in Onshape. Vision Decompose is an agent skill from ReshefElisha/jarvis-onshape-mcp. Look at an engineering reference image (drawing, iso render, photo) and produce a structured feature decomposition BEFORE building anything in Onshape.
When should I use Vision Decompose?
Vision Decompose fits situations like: gives you a reference image and asks you to model it.
How do I install Vision Decompose in Claude Code?
Run `npx skills add ReshefElisha/jarvis-onshape-mcp --skill vision-decompose -a claude-code`. Or copy the skill folder (skills/vision-decompose in ReshefElisha/jarvis-onshape-mcp) into .claude/skills/vision-decompose in your project. Claude Code loads it when a task matches its description.
How do I install Vision Decompose in Codex?
Run `npx skills add ReshefElisha/jarvis-onshape-mcp --skill vision-decompose -a codex`. Or copy the skill folder (skills/vision-decompose in ReshefElisha/jarvis-onshape-mcp) into .agents/skills/vision-decompose in your project. Codex loads it when a task matches its description.
Can I use Vision Decompose in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ReshefElisha/jarvis-onshape-mcp --skill vision-decompose -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/vision-decompose, .gemini/skills/vision-decompose, .github/skills/vision-decompose and .opencode/skills/vision-decompose in your project.
What does Vision Decompose need to run?
SKILL.md names no scripts, command-line tools or credentials: Vision Decompose is instructions for the agent only.
Does Vision Decompose access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Vision Decompose safe to install?
