# Notion to Markdown

This skill provides a high-level workflow for fetching live Notion pages and converting them into clean, localized Markdown files suitable for an Obsidian vault.

## Overview

Unlike bulk migration from exports, this skill leverages the Notion MCP (`notion-fetch`) to retrieve page content directly and then uses the `stable_jarvis.notion_to_obsidian` toolkit to perform surgical processing.

## Execution Workflow

### Step 1: Precise Identification
Use `notion-search` to find the exact page ID or URL.
```bash
# Example search
notion-search query="Leveraging Skills from Unlabeled Prior Data"
```

### Step 2: Fetch and Save Content
Retrieve the raw Notion content and save it to a temporary JSON file.
```bash
# Fetch content via MCP
notion-fetch id="[PAGE_ID]" > temp_fetch.json
```

### Step 3: Local Processing
Run the migration script to convert the JSON content to localized Markdown.
```bash
python skills/notion-to-markdown/scripts/migrate.py temp_fetch.json [OUTPUT_DIR]
```

### Step 4: Verification and Refinement
Inspect the output Markdown. Notion content can sometimes be "jammed" or have deep indentation that script-based normalization might miss. Use the `replace` tool to:
- **Normalize Indentation**: Ensure consistent 2 or 4-space indentation for nested blocks.
- **Fix Block Spacing**: Ensure double newlines exist between headings, details blocks, and paragraphs.
- **Verify Equations**: Check that all `$$` blocks are correctly populated with recovered LaTeX.
- **Final Polish**: Remove any redundant HTML tags or artifacts (e.g., empty `<span>` tags).

## Key Capabilities

- **LaTeX Normalization**: Converts Notion's `$ \dots $` and `$ \dots $` to standard `$...$` and `$$...$$` syntax.
- **Image Localization**: Automatically detects and downloads Notion S3-hosted images, saving them to a local `assets/` folder and updating Markdown links.
- **Frontmatter Mapping**: Extracts Notion properties (Status, Tags, Journal Name, etc.) and maps them to YAML frontmatter.
- **Style Conversion**: Transforms Notion-specific spans (e.g., color backgrounds) to Obsidian highlights (`==text==`).

## Dependencies

- **Conda Environment**: Must use the `jarvis` environment (`conda activate jarvis`).
- **`notion-fetch` MCP Tool**: Required to retrieve page data.
- **`stable_jarvis` package**: Must be installed in editable mode (`pip install -e .`) within the `jarvis` environment.
- **`httpx`**: Used for reliable image downloads.

## Troubleshooting

- **Expired Image URLs**: Notion S3 URLs are temporary. Ensure the `migrate.py` script is run immediately after `notion-fetch`.
- **Missing Content**: If the fetch result is truncated, ensure you are capturing the full output of the `notion-fetch` tool.
