Bilibili Digest Skill

Extract Bilibili (B站) video/column content and transform it into structured, note-ready Markdown with AI-generated summaries, timestamped key points, chapter segmentation, and cross-video integration.

How It Works

This skill operates in a pipeline:

1. Parse – Extract BV/column ID from any Bilibili URL (including b23.tv short links)
2. Fetch – Retrieve video metadata (title, author, duration, views), CC subtitles, and danmaku via Bilibili public APIs
3. Segment – Auto-detect video chapters from timestamps or subtitle gaps
4. Summarize – Call LLM (DeepSeek) to generate structured summary, key points, resources, and action steps
5. Export – Output as Markdown (default), Obsidian, JSON, or prepare for Notion/Feishu

Fallback Strategy for Missing Subtitles

If a video has no CC subtitles, the skill degrades gracefully:

• Generate a summary from title + description + danmaku highlights
• Prompt the user to paste their own notes as enrichment

API Rate Limiting

• Minimum 1-second interval between Bilibili API calls
• Exponential backoff retry (max 3 attempts) on 429 / timeout
• Local cache (24h TTL) at ~/.openclaw/data/bilibili-digest/cache/

Usage

clawhub run bilibili-digest --url \x3Cbilibili-url> [options]

Options

Sample Prompts

1. Extract a single video into structured notes (most common)

clawhub run bilibili-digest --url "https://www.bilibili.com/video/BV1xx411c7mD"
# → Structured Markdown with title, author, key points (with timestamps), chapters, resources

2. Batch process a tutorial series with cross-video merge

clawhub run bilibili-digest \
  --urls '["https://www.bilibili.com/video/BV1xx01","https://www.bilibili.com/video/BV1xx02"]' \
  --cross-video-merge
# → Combined knowledge tree across multiple videos

3. Quick minimal summary for social sharing

clawhub run bilibili-digest --url "https://www.bilibili.com/video/BV1xx411c7mD" \
  --summary-mode minimal
# → One-liner + 3-5 core bullet points

4. Export in Obsidian format with full transcript

clawhub run bilibili-digest --url "https://www.bilibili.com/video/BV1xx411c7mD" \
  --summary-mode detailed --export-format obsidian --include-transcript
# → Obsidian-compatible note with WikiLinks, tags, and YAML frontmatter

5. Mindmap summary for quick review

clawhub run bilibili-digest --url "https://www.bilibili.com/video/BV1xx411c7mD" \
  --summary-mode mindmap
# → Hierarchical mindmap with main topics, subtopics, and key connections,
#   ideal for sharing or importing into mind-mapping tools (XMind, etc.)
