mcpskills.net — Curated AI Skills, MCPs & Agents

Purpose

Turn product design descriptions into a full-page text UI (TUI) that is also machine-readable and drawable:

Output a combined TUI_RENDER for the entire page.
Output a per-component summary table.
Output a consolidated PENCIL_SPEC and PENCIL_BATCH_DESIGN plan (≤25 ops per call).

This skill assumes you follow the shared contract and grid→pixel mapping from tui-front-ui.

Inputs (Recommended)

Provide a page request and a component list:

{
  "page": {
    "name": "Settings",
    "widthCols": 70,
    "canvas": { "widthPx": 390, "heightPx": 844 },
    "grid": { "cellWidthPx": 8, "cellHeightPx": 16 },
    "paddingPx": 24,
    "gapPx": 16,
    "backgroundColor": "#ffffff"
  },
  "components": [
    {
      "id": "cmp_nav",
      "type": "tui-navbar",
      "preferredSizePx": { "widthPx": 342, "heightPx": 56 },
      "zIndex": 10
    }
  ]
}

Output Contract (Mandatory)

  "grid": { "cellWidthPx": 8, "cellHeightPx": 16 },
  "nodes": [],
  "components": []
}

OUTPUT: PENCIL_BATCH_DESIGN

CALL 1:
root=G()
screen=I(root,{type:"frame",name:"Settings"})
U(screen,{width:390,height:844,x:0,y:0})

CALL 2:
...up to 25 ops...

Composition Rules (Strict)

1) Layout model

Use a single page frame as root.
Default layout: vertical stacking within page padding.
Place components by ascending topPx; break ties using zIndex.
Preserve requested zIndex in both COMPONENT_SPEC and drawing order:
- Background blocks first
- Content blocks next
- Overlays (modal/toast) last

2) Geometry calculation

Given:

paddingPx
gapPx
each component preferredSizePx or computed size from its TUI_RENDER grid bbox

Compute:

leftPx = paddingPx
topPx = paddingPx + sum(prev.heightPx + gapPx)
widthPx = canvas.widthPx - paddingPx * 2 unless a component requests a smaller width

3) ASCII rendering layout

Use one outer page frame.
Render each component as a framed block and separate blocks with a single blank line.
Ensure the entire page does not exceed page.widthCols.

4) Interactions

Combine hotkeys and de-duplicate:
- Page-level default: <tab> next, <esc> back
- Component-level only if meaningful
Do not show hotkeys for disabled components.

Pencil MCP Execution Playbook

get_editor_state(include_schema=false)
open_document("new") (or an existing .pen file path)
Apply PENCIL_BATCH_DESIGN in multiple calls (≤25 ops/call).
snapshot_layout(filePath, maxDepth=2, problemsOnly=true)
get_screenshot(filePath, nodeId) for the page frame node

If any layout problems are returned, create a follow-up batch_design patch block.

Example — Settings page with 4 components
