Slides

## When to Use

- User wants to create a slide deck or presentation
- User asks for "slides", "幻灯片", "PPT", or "presentation"
- User wants visual content organized into slides from a topic or URL

## When NOT to Use

- User wants a narrated video without slides (use `/explainer`)
- User wants audio-only content (use `/speech` or `/podcast`)
- User wants a podcast-style discussion (use `/podcast`)
- User wants to generate a standalone image (use `/image-gen`)

## Purpose

Generate slide decks with AI-generated visuals from topics, URLs, or text. By default, slides are generated without audio narration. Narration can be optionally enabled. Ideal for presentations, summaries, and visual storytelling.

## Hard Constraints

- Always read config following `shared/config-pattern.md` before any interaction
- Follow `shared/cli-patterns.md` for execution modes, error handling, and interaction patterns
- Always follow `shared/cli-authentication.md` for auth checks
- Follow `shared/speaker-selection.md` when narration is enabled
- Never hardcode speaker IDs — always fetch from the speakers CLI when the user wants to change voice
- Never save files to `~/Downloads/` or `.listenhub/` — save artifacts to the current working directory with friendly topic-based names (see `shared/config-pattern.md` § Artifact Naming)
- Mode is always `slides` — never `info` or `story` (those are for `/explainer`)
- Only 1 speaker supported (when narration is enabled)
- Default behavior: skip audio (no narration). Only add narration when the user explicitly requests it via `--no-skip-audio`

<HARD-GATE>
Use the AskUserQuestion tool for every multiple-choice step — do NOT print options as plain text. Ask one question at a time. Wait for the user's answer before proceeding to the next step. After all parameters are collected, summarize the choices and ask the user to confirm. Do NOT call any CLI command until the user has explicitly confirmed.

</HARD-GATE>

## Step -1: CLI Auth Check

Follow `shared/cli-authentication.md`. If the CLI is not installed or the user is not logged in, auto-install and auto-login — never ask the user to run commands manually.

## Step 0: Config Setup

Follow `shared/config-pattern.md` Step 0 (Zero-Question Boot).

**If file doesn't exist** — silently create with defaults and proceed:
```bash
mkdir -p ".listenhub/slides"
echo '{"outputMode":"inline","language":null,"defaultSpeakers":{}}' > ".listenhub/slides/config.json"
CONFIG_PATH=".listenhub/slides/config.json"
CONFIG=$(cat "$CONFIG_PATH")
```
**Do NOT ask any setup questions.** Proceed directly to the Interaction Flow.

**If file exists** — read config silently and proceed:
```bash
CONFIG_PATH=".listenhub/slides/config.json"
[ ! -f "$CONFIG_PATH" ] && CONFIG_PATH="$HOME/.listenhub/slides/config.json"
CONFIG=$(cat "$CONFIG_PATH")
```

### Setup Flow (user-initiated reconfigure only)

Only run when the user explicitly asks to reconfigure. Display current settings:
```
当前配置 (slides)：
  输出方式：{inline / download / both}
  语言偏好：{zh / en / 未设置}
  默认主播：{speakerName / 使用内置默认}
```

Then ask:

1. **outputMode**: Follow `shared/output-mode.md` § Setup Flow Question.

2. **Language** (optional): "默认语言？"
   - "中文 (zh)"
   - "English (en)"
   - "每次手动选择" → keep `null`

After collecting answers, save immediately:
```bash
NEW_CONFIG=$(echo "$CONFIG" | jq --arg m "$OUTPUT_MODE" '. + {"outputMode": $m}')
echo "$NEW_CONFIG" > "$CONFIG_PATH"
CONFIG=$(cat "$CONFIG_PATH")
```

## Interaction Flow

### Step 1: Topic / Content

Free text input. Ask the user:

> What would you like to create slides about?

Accept: topic description, text content, URL(s), or any combination.

### Step 2: Language

If `config.language` is set, pre
