How developers (and non-developers) build Claude Apps

There is no separate "Apps SDK" API surface documented on Anthropic's own site as of this fetch -- Claude Apps are built entirely through natural-language conversation inside the Claude.ai Artifacts space, not through a distinct code-first SDK. Anthropic's own tutorial describes the workflow directly:

The four-step workflow (per Anthropic's own tutorial)

1. Head to "artifacts" in your sidebar -- starting there signals intent to Claude so it can help build the best possible version of the app.
2. Start by exploring your problem -- share the idea and the underlying problem in plain language.
3. Let Claude interview you -- Claude asks follow-up clarifying questions about the vision (Anthropic's example: "what age range are you trying to teach?").
4. Ask Claude to build it -- once the idea is clarified, directly request the artifact ("Can you create this for me?" / "Let's build this now").

Iterating and debugging

"Simply ask Claude to modify your artifact ('make the buttons bigger,' 'add a timer,' 'change the color scheme'). Each request builds on previous versions while Claude maintains context about what you've built and why." For fixes: "click 'Fix with Claude' or describe the problem in plain language ('the calculator isn't working with decimals,' 'the game crashes at level 3'). No need to understand technical error messages." The tutorial also notes you can "turn on extended thinking or use a more intelligent model" for deeper debugging, and that you can fork any prior message into a new conversation branch to try different approaches without losing the original.

Sharing

Publishing generates a shareable link. Logged-out viewers get view-only access (with one exception: AI-powered artifacts require sign-in even to view, since usage draws on the viewer's own account). Signed-in Claude users can additionally "remix & customize" -- copy the artifact into their own account to modify, without altering the original creator's version.

Real documented examples cited directly by Anthropic

• A mood canvas that creates colorful visualizations from user input.
• An email writing assistant that turns raw thoughts into polished communications.
• A language tutor that lets a user chat and learn in a chosen language.
• A project dashboard generator producing Gantt charts, progress bars, and milestone tracking from user input.
• Music producer Rick Rubin's "The Way of Code" -- 81 meditations paired with interactive artifacts anyone can reshape with Claude, cited by Anthropic's own blog post as an example of "when conversation becomes creation."

Honest gap: this page and the announcement post are the only two Claude-Apps-specific build guides located this session -- no dedicated, separate "Apps SDK" reference document (distinct from the general Artifacts + MCP mechanism) was found.
