AgentHub Studio
Studio is a scratch surface AgentHub renders beside this session. You render into it; the user points, comments, tweaks, and sends feedback back to you. Nothing you file here touches the project.
Which tool
agenthub_design — several variants of one component, side by side on an infinite canvas ("show me 4 versions of the primary button", "compare a dense vs airy card"). Each variant is an HTML fragment + CSS; AgentHub isolates each variant's CSS to its own artboard.agenthub_artifact — one self-contained HTML document ("render this report", "mock up the landing page", "draw the flow"). Served verbatim; inline CSS/JS is fine.agenthub_list_artifacts — call first when the user is refining something already on screen; re-file with that id so the panel updates in place instead of stacking a near-duplicate.agenthub_get_artifact — the current content of one artifact, including edits the user made in the panel. Call it with variant=<name> when the user picks one, and before re-filing an existing canvas so you start from what they have.
Filing a canvas well
- Decide the axis of comparison (fill vs outline vs soft; density; tone) — 3–6 variants, each with a short
name and a one-line notes rationale.
- Write plain CSS per variant (
.btn, body, :root variables all work; scripts are stripped).
- Declare shared
props for the knobs worth comparing across every variant — e.g. radius (slider, unit px), accent (color), label (text), shadow (toggle) — and reference each one from variant CSS as var(--<name>) (text/select props can also fill an element marked data-prop="<name>"). A declared prop no variant uses is rejected. The user moves one control and every variant updates.
- Pass
sourcePath when you know the real component the variants explore; it is only used if the user later asks to implement one.
- After filing, say it is in the Studio panel and stop — do not also edit files.
Handling what comes back
- Comments, crops, tweak requests arrive as prompts naming the artifact id (and the variant). Re-file with the same id and change only what was asked. Do not edit project files for these.
- Edits the user makes with the panel's Edit tool are already saved into the canvas — you are not asked to apply them. They are simply part of the variant from then on.
- Choosing a variant is the one request that asks for code. It arrives either as an "Implement" prompt from the panel (it carries the current html/css) or in conversation ("let's go with the ghost one", "the second option", "that card"). In the conversational case call
agenthub_get_artifact with variant=<name> (map ordinals and descriptions to the variant names from the list), then implement exactly that html/css in the real component, preserving behaviour and public API, following project conventions rather than pasting the markup verbatim, and list the files you changed. If it is unclear which variant they mean, ask.
Boundaries
Inside AgentHub, prefer Studio over claude.ai artifacts or the /design skill so the result appears in the panel the user is watching. Never write into the repository as part of iterating on a canvas or artifact.
1---2name: agenthub-studio3description: Render UI variants or any visual — mockups, reports, diagrams, dashboards — into AgentHub's Studio panel beside this session, on a scratch surface that never touches project files. Use when the user asks to see, compare, mock up, or explore options, versions, or variants of a component or screen, asks "what would it look like", or wants a rendered document.
