Vibe-code Fusion 360 add-ins.
Give your AI agent deep knowledge of Fusion add-ins that use an HTML and JavaScript architecture for maximum UI flexibility. A complete, self-contained kit — no other purchase required.
One-time · self-contained · works with Claude, Codex, Cursor, Copilot & Gemini.
The problem
Fusion's add-in API is thinly documented.
The docs are thin and the palette architecture isn't obvious, so a general-purpose agent guesses at the API — and gets it wrong. You lose days to gotchas nobody wrote down.
The bridge is easy to get wrong
Palette architecture, event wiring, the HTML/JS-to-Python bridge — subtly wrong in ways that only show up at runtime.
The agent guesses
Without Fusion-aware steering, the AI guesses at API names and patterns — confidently, and wrong.
Every add-in starts from zero
No scaffolder, no templates, no conventions — just a blank folder and a docs site that doesn't quite answer the question.
Why listen to me
I build these add-ins — and taught my agent how.
I ship real Fusion tooling through the same thinly-documented API you're staring at. This kit is the steering I use to make my own agent good at it — packaged so yours starts out the same way.
The plan
Three steps to add-ins that ship
Drop in the bootstrap
Add the scaffolder, templates, and steering docs to your add-in folder.
Your agent learns Fusion
It picks up the API gotchas, palette patterns, and conventions automatically.
Build & test real add-ins
Ship add-ins that hold up — and a workflow you can repeat for the next one.

Skills your agent learns
Reusable commands your agent already knows how to run. Invoke by name or in plain language — your AI follows the skill's playbook either way.
/jgl-fusion-checkRun the full and detailed test suite. Activate via "check", "/jgl-fusion-check", "verify", "is everything passing"/jgl-fusion-commitStage and commit changes locally with a meaningful message. Does NOT push./jgl-fusion-mcpRegister the Autodesk Fusion MCP server and validate it's actually live — an active preflight before any MCP-dependent work (headless integration tests, API probing, viewport screenshots)./jgl-fusion-pushPush committed changes to the remote, with branch-aware safety./jgl-fusion-review-codeReview the codebase for structural issues — duplication, large files, dead code, dependency health, and Fusion API misuse. Produces a refactor plan if warranted. Activate via "review code", "/jgl-fusion-review-code", "code review", "anything need refactoring?", or "look over the code"./jgl-fusion-review-testingAudit the test suite across all three Fusion test layers — Python unit, TypeScript unit, and Fusion integration. Produces a plan to improve testing if warranted. Activate via "review tests", "/jgl-fusion-review-testing", "audit tests", "how are my tests?", "improve test quality", or before a refactor./jgl-fusion-scaffoldScaffold the file/folder structure for a new add-in/jgl-fusion-scopeGuided-start interview for a new Fusion 360 add-in — a 15-20 minute conversation about what you're building, which Fusion workspaces it touches, whether it reads or mutates the model, how it persists state, and the dev/MCP loop. Produces docs/SCOPE.md, adds a Project context section to CLAUDE.md, sets up the Fusion MCP server, and hands the scaffold inputs to /jgl-fusion-scaffold. Use on a new/empty add-in project, or when the user says "help me get started", "scope this out", "what am I building"./jgl-fusion-setup-testingWire up the three test layers on a Fusion add-in that doesn't have one — pytest+pytest-cov for Python, Vitest for the webapp, and the in-Fusion integration runner./jgl-fusion-statusSession checkpoint for a Fusion add-in — what changed, what's still open, anything risky uncommitted, integration-test hash freshness.
Wait, what's a "skill"?
From Napoleon Dynamite (2004): “I don't even have any good skills. You know like num-chuk skills, bow hunting skills, computer hacking skills. Girls only want boyfriends who have great skills!”
Modern AI coding tools let you teach your agent skills — named playbooks it can recognize and follow. Each card above is one your agent gets when you install the kit.
What's at stake
The difference Fusion-aware steering makes
With a generic agent
- Invented API calls that don't exist
- Days lost to undocumented gotchas
- A blank folder every single time
- Add-ins that break on the next update
With the Fusion kit
- An agent that knows the real API
- A scaffolder + templates to start fast
- Good dev practice baked in
- Add-ins you can test and trust
