# bilibili-cli Skill

A CLI tool for interacting with Bilibili (哔哩哔哩). Use it to fetch video info, search content, browse user profiles, download audio, and perform interactions like liking or triple-clicking.

## Prerequisites

```bash
# Install (requires Python 3.10+)
pip install bilibili-cli
# Or: uv tool install bilibili-cli
```

## Authentication

Most read commands work without login. Subtitles, favorites/following/watch-later/history, feed, and interactions require login.

```bash
bili status                    # Check if logged in
bili login                     # QR code login (if not authenticated)
```

Authentication auto-detects local browser cookies (Chrome/Firefox/Edge/Brave). If cookies are found and valid, no manual login needed.

bili hot --json | python3 -c "import sys,json; print(json.load(sys.stdin)['list'][0]['title'])"                # First trending title
bili user 946974 --json | python3 -c "import sys,json; print(json.load(sys.stdin)['user_info']['name'])"       # Username
```

```bash
# Get a video's subtitle text for summarization
bili video BV1ABcsztEcY --subtitle

# Extract audio for speech-to-text (ASR)
# Segments are saved to /tmp/bilibili-cli/{title}/seg_000.wav, seg_001.wav, ...
bili audio BV1ABcsztEcY --segment 25

# Find a user's latest video BV ID
bili user-videos 946974 --max 1 --json | python3 -c "import sys,json; print(json.load(sys.stdin)[0]['bvid'])"

# Check if logged in before performing actions
bili status && bili like BV1ABcsztEcY

# Search and get first result
bili search "topic" --type video --json | python3 -c "import sys,json; r=json.load(sys.stdin); print(r[0]['bvid'] if r else 'not found')"
```
