Best use case

tui-line is best used when you need a repeatable AI agent workflow instead of a one-off prompt. It is especially useful for teams working in multi. Generate and render a pixel-precise ASCII TUI Line component with complete output blocks (TUI_RENDER, COMPONENT_SPEC, PENCIL_SPEC, PENCIL_BATCH_DESIGN) for Pencil MCP drawing workflows. Use when the user asks to create a line in a terminal UI, text-based interface, or Pencil MCP project.

Users should expect a more consistent workflow output, faster repeated execution, and less time spent rewriting prompts from scratch.

Practical example

Example input

Use the "tui-line" skill to help with this workflow task. Context: Generate and render a pixel-precise ASCII TUI Line component with complete output blocks (TUI_RENDER, COMPONENT_SPEC, PENCIL_SPEC, PENCIL_BATCH_DESIGN) for Pencil MCP drawing workflows. Use when the user asks to create a line in a terminal UI, text-based interface, or Pencil MCP project.

Example output

A structured workflow result with clearer steps, more consistent formatting, and an output that is easier to reuse in the next run.

When to use this skill

Use this skill when you want a reusable workflow rather than writing the same prompt again and again.

When not to use this skill

Do not use this when you only need a one-off answer and do not need a reusable workflow.
Do not use it if you cannot install or maintain the related files, repository context, or supporting tools.

## Purpose

- Produce an ASCII Text UI (TUI) representation of **Line**.
- Always output layout attributes (top/left/width/height, spacing, colors, typography, zIndex).
- Always output Pencil MCP–ready specs and a `batch_design` plan (≤25 operations per call).

## Workflow

1. **Parse input** — Read the input model JSON (widthCols, grid, props, state, style, typography, layout, hotkeys).
2. **Calculate layout** — Convert column/row positions to pixel coordinates using the grid (cellWidthPx=8, cellHeightPx=16).
3. **Render TUI_RENDER** — Build the monospace ASCII art with box-drawing characters, respecting widthCols.
4. **Build COMPONENT_SPEC** — Emit the JSON spec with bbox, style, typography, state, and hotkeys.
5. **Build PENCIL_SPEC** — Emit the canvas and component list for Pencil MCP.
6. **Plan PENCIL_BATCH_DESIGN** — Emit batch_design calls (max 25 ops per call) to create the design in Pencil.
7. **Validate** — Verify bbox dimensions in COMPONENT_SPEC match the TUI_RENDER grid; confirm batch ops stay within the 25-op limit.

## Input Model (Recommended)

```json
{
  "widthCols": 70,
  "grid": { "cellWidthPx": 8, "cellHeightPx": 16 },
  "props": {},
  "modelValue": null,
  "state": { "focused": false, "disabled": false, "loading": false, "error": null },
  "style": {
    "fillColor": "#ffffff",
    "textColor": "#111111",
    "strokeColor": "#e5e7eb",
    "strokeThickness": 1,
    "cornerRadius": 12
  },
  "typography": { "fontFamily": "Inter", "fontSize": 14, "fontWeight": 400, "lineHeight": 20 },
  "layout": { "paddingPx": 16, "gapPx": 8 },
  "hotkeys": []
}
```

## Output Contract (Mandatory)

### OUTPUT: TUI_RENDER

...monospace-only text...
```

U(cmpText,{x:40,y:56,width:310,height:20,textColor:"#111111",fontFamily:"Inter",fontSize:14,fontWeight:600})
```

## Rendering Rules (Component-Level)

Follow the shared rules from `tui-front-ui`:
- No TAB characters.
- Do not exceed `widthCols`.
- Provide a header row, body area, and minimal hotkeys if interactive.
- `disabled=true` must suppress interaction hints.
- `loading=true` must show a stable placeholder.
- `error!=null` must be printed in a single line footer (truncated to width).

## Examples (Must include all output blocks)
