Generate guardrailed UI from natural language. Emits constrained JSON that a Preact runtime renders. Use when the request is for a dashboard with metrics, charts, or tables; an admin panel; a data visualization interface; or a form-based application.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# JSON Render UI
## Overview
Transform natural language UI requests into working dashboards and applications. Claude acts as the translation layer (prompt → JSON), the skill provides the rendering runtime (JSON → UI).
**Architecture:**
```
User prompt → Claude (constrained by catalog) → UITree JSON → Preact renderer → UI
```
## Output Format
Claude emits a **UITree** structure:
```json
{
"root": "main",
"elements": {
"main": {
"key": "main",
"type": "Grid",
"props": { "columns": 2, "gap": "md" },
"children": ["metric1", "metric2"]
},
"metric1": {
"key": "metric1",
"type": "Metric",
"props": {
"label": "Revenue",
"valuePath": "/revenue",
"format": "currency"
}
},
"metric2": {
"key": "metric2",
"type": "Metric",
"props": {
"label": "Growth",
"valuePath": "/growth",
"format": "percent"
}
}
},
"data": {
"revenue": 125000,
"growth": 0.15
}
}
```

How to install
mdr add oaustegard/claude-skills/json-render-ui@sha256:7d499ca410a4ea3eThe line at the top of this page pins the label v0.0.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
