notebooklm (13 tools)

Deep research + 9 downloadable artifact types (podcast, slides, report, quiz, flashcards, mindmap, datasheet, study_guide). ⚠️ infographic download is unreliable — use slides instead.

Management: create_notebook, list_notebooks, delete_notebook Research: add_source, ask, summarize, list_sources, research(mode="fast"|"thorough") Artifacts: generate_artifact(type, lang?), download_artifact(type, output_path) Pipelines: research_pipeline(sources, questions, output_format), trend_research(geo?, count?, platform?)

Video Synthesis (slides + podcast -> MP4):

1. Generate slides (PDF) + audio (podcast M4A) — sequentially
2. Download both
3. pdftoppm -png -r 300 slides.pdf slides_page
4. ffmpeg -framerate 1/$per_slide -pattern_type glob -i 'slides_page-*.png' -i audio.mp3 -c:v libx264 -pix_fmt yuv420p -c:a aac -shortest output.mp4

Visual Content Generation

Use NotebookLM to generate all visual content. It produces professional-quality slides and mind maps — far better than any alternative.

⛔ 嚴格禁止：不得使用 Pillow/PIL、ImageMagick、Python 程式碼或 HTML+Playwright 生成圖卡。 所有圖卡一律透過 NotebookLM nlm_generate(type="slides") 生成。

⚠️ Do NOT use infographic (download unreliable). Use slides for all visual content. ⚠️ NLM slides 多頁時 → 必須全部上傳 → 用 carousel_urls 發文（不要只發一張）。

Image Cards & Slides (圖卡 / 簡報)

Workflow: Create a NotebookLM notebook with the content as a text source, then generate the visual artifact.

1. create_notebook(title="Post Visual", text_sources=["<post content + key data points>"])
2. generate_artifact(name_or_id, "slides", lang="zh-TW")   → PDF slides (best for cards)
3. download_artifact(name_or_id, "slides", "downloads/card.pdf")

Choose artifact type by use case:

Need	Artifact Type	Output
Single image card	slides (1 slide)	PDF → export as image
Multi-slide carousel	slides (N slides)	PDF → split per page
Data visualization	slides	infographic ⚠️ download unreliable — use slides
Topic overview	mindmap	Mind map diagram
Detailed report	report	Formatted document
Study material	flashcards / study_guide	Learning cards

Carousel Posts (輪播貼文)

For multi-image carousel (Threads supports 2-20 images):

1. Create notebook with content organized as numbered sections (one per slide)
2. generate_artifact(name_or_id, "slides") → multi-page PDF
3. Download and split: pdftoppm -png -r 300 slides.pdf slide
4. Upload EVERY image — call upload_image for EACH slide PNG:

   upload_image(file_path="downloads/slide-1.png") → url1
   upload_image(file_path="downloads/slide-2.png") → url2
   upload_image(file_path="downloads/slide-3.png") → url3
   ...repeat for ALL slides
   

5. Publish as carousel — pass ALL URLs to publish_to_threads:

   publish_to_threads(text="...", carousel_urls=[url1, url2, url3, ...])
   

   Do NOT use image parameter — use carousel_urls when there are 2+ images.

⚠️ CRITICAL: When slides have multiple pages, you MUST use carousel_urls (not image). Single image parameter only posts the first image. carousel_urls posts ALL images as a swipeable carousel.

Video (影片)

Combine slides + podcast audio into MP4:

1. generate_artifact(name_or_id, "slides") → PDF
2. generate_artifact(name_or_id, "podcast") → M4A audio (run sequentially, NOT parallel)
3. Download both artifacts
4. pdftoppm -png -r 300 slides.pdf slides_page
5. ffmpeg -framerate 1/$per_slide -pattern_type glob -i 'slides_page-*.png' -i audio.mp3 -c:v libx264 -pix_fmt yuv420p -c:a aac -shortest output.mp4

Tips for Better Visuals

• Language: Always pass lang="zh-TW" for Traditional Chinese content
• Rich text sources: The more context you feed into the notebook, the better the visual output
• One topic per notebook: Don't mix unrelated topics — create separate notebooks
• Add URLs as sources: add_source(name_or_id, url="...") for reference material — NotebookLM will incorporate key data into visuals

Mandatory Rules

0. Workspace Containment

All files MUST be saved within the session workspace directory. Use relative paths like downloads/card.pdf. NEVER use ~/Downloads, ~/Desktop, or any absolute path outside the workspace.

1. Read Original Sources

NEVER write content based on titles/metadata alone.

• Single topic: read >= 1 primary source via browser_markdown(url)
• Controversial: read >= 2 sources (both sides)
• Data claims: find original data source

2. Timeline Verification

Every fact must have a verified timestamp. Discard anything > 48 hours old.

Source age	Allowed	Forbidden
Today	"today" "just now"	-
1-3 days	"recently" "the other day"	"just" "latest"
4-7 days	"last week" "this week"	"just" "yesterday"
8-30 days	"this month"	"last week" "just"
>30 days	"earlier" "this year"	any freshness words

3. Use ALL Sources

get_trending with sources="" to query ALL 20 sources. Do NOT filter unless user explicitly asks.

Meta Patent-Based Scoring (5 Dimensions)

#	Dimension	Weight	Check
1	Hook Power	25%	First line: number or contrast, 10-45 chars
2	Engagement Trigger	25%	CTA anyone can answer, direct "you" address
3	Conversation Durability	20%	Has contrast/both sides, creates discussion
4	Velocity Potential	15%	Timely, 50-300 chars, urgency language
5	Format Score	15%	Mobile-scannable, line breaks, no text walls

Quality Gates (ALL must pass before publishing):

• Overall Score >= 70
• Conversation Durability >= 55
• Hook: 10-45 chars with number or contrast
• CTA: clear question or poll
• Timeline: all time words verified
• Source: every claim traceable
• No AI filler words

Pipeline Workflow

1. Discover: get_trending(sources="", geo, count=20)
2. Read Source: browser_markdown(url) — MANDATORY
3. Verify Timeline: Check dates, discard stale
4. Research: browser_markdown + WebSearch, 2-3 sources min
5. Brief: get_content_brief(topic)
6. Create: Write -> patent check (5 dimensions)
7. Score: get_scoring_guide — self-score (>= 70)
8. Review: get_review_checklist — final check
9. NotebookLM (optional): create notebook -> generate artifacts
10. Publish: provide ready-to-post content or use publish tool
