# A legend for your source labels — Gemini Notebook prompt

> If you use labels or naming conventions on sources ('[DRAFT]', '[2019 — dated]', '[opposing view]'), the notebook doesn't know what they mean until you tell it. This template turns your naming scheme into instructions the model actually follows.

## The prompt

```
My sources use a naming convention. Interpret it as follows:

- Sources marked [PRIMARY] — original documents (contracts, papers, transcripts). Prefer these for every factual claim.
- Sources marked [SECONDARY] — commentary and summaries. Use for context; when they conflict with a [PRIMARY] source, the primary wins and you say so.
- Sources marked [DRAFT] or [INTERNAL] — unfinished thinking. Never quote these as established positions.
- Sources marked [DATED — year] — accurate as of that year. Flag the age whenever you rely on one.
- Sources marked [OPPOSING] — included to represent the other side. Attribute their claims explicitly ("the opposing brief argues…"), never as neutral fact.

[Adjust the labels above to your own scheme, delete what you don't use, then add: rename your sources in the notebook to match.]
```

## How to use it

1. Open your notebook and click Customize (chat settings) in the chat panel.
2. Paste the prompt as the notebook's custom instructions and save.
3. It now applies to every question you ask in this notebook.

Square brackets mark the parts you replace with your own topic or question.
