ascii-cli-logo-banner

## When to use this skill
**CRITICAL TRIGGER RULE**
- Use this skill ONLY when the user explicitly mentions the exact skill name: `ascii-cli-logo-banner`.

**Use this skill when the user says they want:**
- A startup banner / logo / welcome screen for a CLI or service

**Trigger phrases include:**
- "ascii-cli-logo-banner"
- "use ascii-cli-logo-banner"
- "用 ascii-cli-logo-banner"
- "使用 ascii-cli-logo-banner 生成启动 Banner"
- "用 ascii-cli-logo-banner 做一个 ASCII Logo"

## Boundary
- This skill is a routing/selection entry point. It does not provide its own generator implementation.
- For built-in (no external font engine): use `ascii-cli-logo-banner-python`.
- For TAAG/FIGlet style (FIGfont spec, smushing layouts): use `ascii-cli-logo-banner-figletjs`.

## How to use this skill
### Inputs (recommended)
- brandName (required)
- version (optional)
- author (optional)
- repoUrl / docsUrl (optional)
- width (default 80)
- slogan (optional, centered line under the logo)
- hint (optional, centered line under the slogan)
- glyph (ascii | block, default ascii)
- center (default true)
- rule (default true; set false for logo-only hero output)
- style (block | outline | thin, default block)
- colorMode (none | ansi256, default none; logo only in scripts)
- includeCta (default true)

### Outputs (required)
- bannerPlain: ASCII-only full banner (logo area + info block + horizontal rule)
- compactPlain: compact banner for `width < 60` (single-line title + rule + 1-2 info lines)
- plainTextFallback: no-color fallback when ANSI is enabled (same structure as bannerPlain)
- embedNotes: 3-5 embedding notes (CLI start / service start / README / tickets)

### Steps
1. Decide width and fallback:
   - Default `width=80`
   - If `width < 60`, output `compactPlain` and skip the big-letter logo
2. Generate an ASCII-only logo:
   - Avoid full-width characters and ambiguous-width Unicode
   - Ensure each line is `<= width`
3. Compose the banner structure (recommended order):
   - Logo area (or a single-line title in compact mode)
   - Horizontal rule: exactly `width` characters (`-` or `=`)
   - Info block: Name / Version / Repo / Docs / Author (only include fields provided)
   - Optional CTA: e.g. `Run: <command>` or `Docs: <url>`
4. Optional ANSI coloring (must not break alignment):
   - Colorize visible characters only; do not colorize spaces
   - Always provide `plainTextFallback`

### Routing Decision

| Need | Skill to use | Why |
|------|-------------|-----|
| Simple built-in font, no npm/node deps | `ascii-cli-logo-banner-python` | Uses a built-in 5x5 font, Python only |
| TAAG/FIGlet fonts, layout smushing | `ascii-cli-logo-banner-figletjs` | Full FIGfont spec via figlet.js |

**Example**: For a quick startup banner with `brandName="MyApp"` and no external font engine needed, route to `ascii-cli-logo-banner-python`. For a FIGlet "Standard" or "Big" font banner with horizontal smushing, route to `ascii-cli-logo-banner-figletjs`.

## Script (optional)
- Use `ascii-cli-logo-banner-python` for the Python implementation.
- Use `ascii-cli-logo-banner-figletjs` for the figlet.js/FIGfont implementation.

## Examples
- See examples in the two implementation skills:
  - `ascii-cli-logo-banner-python/examples/*`
  - `ascii-cli-logo-banner-figletjs/examples/*`

## Quality checklist
1. Does not wrap or misalign at 80 columns; no trailing spaces
2. Copy-pastes cleanly into logs/email/tickets
3. Never prints secrets (tokens, internal URLs, personal data)
