NotebookLM — Browser Automation

Requires: A browser automation environment (Claude Code CLI with computer-use, Claude Chrome Extension, or equivalent). Skill will gracefully fail in non-automation contexts with a clear "not supported" message.

Critical: This skill is the only browser-automation skill in the v2 collection. It does NOT follow the research-pack Agent Integrity Rules convention. Different constraints apply (UI dynamics, async generation, login walls).

Step 0: Browser Context Setup (Mandatory)

Before any other action, verify browser automation is available:

1. Check whether browser-control tools are loaded in the harness (screenshot, click, find-element, navigate)
2. If unavailable → halt with clear message: "This skill requires browser automation. Currently in {context}. Cannot proceed. Use Claude Code CLI with computer-use, Claude Chrome Extension, or equivalent."
3. If available → take initial screenshot, navigate to https://notebooklm.google.com
4. Detect login wall via screenshot. If login screen detected: halt with "Please log in to NotebookLM in the browser, then re-invoke this skill." Never attempt to handle login automatically.

Phase 0: Grill-Me Intake (Action-Routing)

Up to 4 forcing questions, one at a time, dependency-ordered. Most invocations stop at Q3.

Q1 (root) — Action

What do you want me to do? Pick one:

1. Read / extract — ask a question of an existing notebook
2. Add a source — push content (URL, text, file, Google Doc, or synthesized content) into a notebook
3. Generate a Studio output — Audio Overview, Study Guide, Briefing Doc, Timeline, FAQ, Infographic, Slides, or Mind Map
4. Create a new notebook — initialize with title + initial sources

Why I'm asking: Each action takes a different path through the UI and requires different parameters. Naming the action upfront prevents wasted screenshots and lets me ask only the follow-up questions that apply.

Forcing choice. If the user says "open NotebookLM" without specifying an action, refuse to start and re-ask Q1.

Q2 (depends on Q1) — Notebook identity

Which notebook? (asked for actions 1, 2, 3 — not for "create new")

Why I'm asking: If you give me a name, I'll search the homepage; if you give me a URL, I'll navigate directly. Names that are ambiguous will get a disambiguation prompt with screenshots.

For action 4 (create new): replace with "What's the title for the new notebook?"

Q3 (depends on Q1) — Action-specific parameter

Action 1 (read/extract):

"What's the question to ask the notebook? Use natural phrasing — the notebook's chat handles it best."

Action 2 (add source):

"What source type? Pick one:

1. URL / website / YouTube link
2. Copied text (paste here or point at content)
3. File upload (provide absolute path)
4. Google Doc (link)
5. Synthesized content (I'll pre-process and add as 'Copied text')

Why I'm asking: Each source type goes through a different sub-flow in the Add Source dialog. Picking upfront saves a step."

Action 3 (Studio output):

"Which Studio output? Audio Overview / Study Guide / Briefing Doc / Timeline / FAQ / Table of Contents / Infographic / Slides / Mind Map. And: any custom-prompt direction? Default prompts produce mediocre output — I always open the customization menu and write a detailed prompt. Tell me the angle or audience.

Why I'm asking: The output type sets the UI button to find. The custom prompt is mandatory for quality."

Action 4 (create new):

"Initial sources? Provide URLs, file paths, or 'I'll add later'."

Q4 (depends on Q1 = action 3) — Studio custom prompt detail

Tell me the angle, audience, and length for the Studio output. Examples:

• Audio Overview: "Two-host conversation for a non-technical executive, 8–10 min, focus on business implications not technical depth"
• Infographic: "Decision-tree style, action-oriented, 6 panels max, monochrome navy"
• Study Guide: "Undergrad-level, definitions + 3 practice questions per concept"

Why I'm asking: This becomes the custom prompt. Default Studio prompts produce mediocre output — specific direction produces sharp output.

Asked only for Studio output generation (Q1=3). Skip otherwise.

Stop condition: After Q4 (or earlier with dependency skips), commit and start the action sequence.

See references/studio_output_custom_prompts.md for the canon.

Notebook Discovery

For actions 1-3 (require existing notebook):

1. Navigate to homepage → screenshot
2. If user provided URL → navigate directly
3. If user provided name:
   • Use semantic find() to locate notebook card by visible title text
   • If multiple matches → screenshot homepage, list options, ask user to specify
   • If no match → ask user to provide URL or confirm spelling

For action 4 (create new):

1. Locate "New notebook" button on homepage
2. Click → set title from Q2
3. Add initial sources per Q3

Action 1: Read / Extract

1. Open the notebook (notebook discovery above)
2. Locate chat input (semantic find or screenshot coordinates)
3. Type the question (use the user's natural phrasing from Q3)
4. Submit (Enter or send button)
5. Wait 3–5 seconds
6. Screenshot the response area
7. Extract and present in clean format (not raw chat dump)

Action 2: Add Sources

Sub-flows per source type:

After every add: wait for ingestion spinner, screenshot to confirm success.

Synthesized content pattern (powerful): instead of asking NotebookLM to ingest a raw URL with potentially noisy content, pre-process the content (extract main article, strip nav/ads/comments), then add as "Copied text". Produces dramatically better summarization.

Action 3: Studio Outputs

All 9 output types supported: Audio Overview, Study Guide, Briefing Doc, Timeline, FAQ, Table of Contents, Infographic, Slides, Mind Map.

Mandatory workflow:

1. Locate Studio panel (right side; may need toggle)
2. Find the specific output button for the requested type
3. Open customization menu (chevron/arrow next to button) — NOT the main button
4. Write detailed custom prompt (from Q4)
5. Confirm and submit
6. Do NOT wait for completion — confirm generation started, notify user, return

Custom prompt examples (4 output types)

Audio Overview:

"Two-host conversation between a researcher and an experienced practitioner. Audience: non-technical executive making a budget decision. Length: 8-10 minutes. Focus on business implications, not technical depth. Include one concrete example per major point. Acknowledge counter-arguments briefly."

Infographic:

"Decision-tree style. Action-oriented (each panel ends with a decision or action). 6 panels max. Monochrome navy + amber highlight. Each panel has: title (4-6 words), 1-2 sentence body, decision/action line. No filler panels."

Study Guide:

"Undergraduate-level (define every technical term). Structure: 6 concepts × 4 elements each (definition / why it matters / one worked example / 3 practice questions). Practice questions Bloom-higher-order (apply/analyze), not recall."

Slides (slide deck):

"12 slides max. 1-2 sentences per slide body. Presenter notes per slide with: one concrete example + one likely audience objection + how to address it. No bullet points in slide bodies — prose only. End with one-slide call-to-action."
