Transfer a Notion page to the Wasp blog

Given a Notion page URL, convert it into an MDX blog post for the Wasp website at web/blog/.

Step 1: Fetch the Notion page

1. Extract the page ID from the URL (the UUID at the end, formatted with dashes: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).
2. Use mcp__notion__API-retrieve-a-page to get page metadata (title, properties).
3. Use mcp__notion__API-get-block-children to fetch all content blocks. Notion paginates at 100 blocks — check has_more and next_cursor to fetch all pages.

Step 2: Parse the content

The Notion page may contain WIP/working notes before and after the actual blog post. Ask the user where the actual post starts and ends if unclear. Typically:

• The post starts at the first heading_1 block
• WIP sections are often marked with a ## WIP heading or appear after a divider near the end

Use a Python script (via Bash) to parse the JSON block data because it can be very large (50K+ tokens). The script should:

• Extract blocks in the post range
• Convert each block to markdown based on its type:
  • heading_1/2/3 → # / ## / ###
  • paragraph → plain text with formatting
  • bulleted_list_item → -
  • numbered_list_item → 1.
  • code → fenced code block with language
  • image → collect URL and caption
  • quote → >
  • callout → > {emoji}
  • divider → ---
  • table_of_contents → skip (Docusaurus handles this)
• Preserve rich text formatting: bold (**), italic (*), code (`), strikethrough (~~), links ([text](url))
• Collect all image URLs and captions separately

Step 3: Download and optimize images

1. Create directory: web/static/img/<post-slug>/
2. Download all images using curl (Notion URLs are temporary signed S3 URLs — download immediately).
3. Give images descriptive names based on their context/caption.
4. Convert all images to WebP using cwebp -q 85 for smaller file sizes.
5. Remove the original files after conversion.

Step 4: Create the MDX file

Create web/blog/YYYY-MM-DD-<slug>.mdx following these conventions:

Frontmatter:

---
title: "Post Title"
authors: [authorHandle]  # from web/blog/authors.yml
image: /img/<post-slug>/banner.webp
tags: [wasp, tag2, tag3]  # 3-6 lowercase tags
keywords: ["keyword1", "keyword2", ...]  # 10+ for SEO
description: "SEO summary under 160 chars."
---

Content rules:

• Add import { ImgWithCaption } from './components/ImgWithCaption'; after frontmatter
• Add {/* truncate */} after the opening hook paragraph (this controls the blog listing excerpt)
• Use <ImgWithCaption source="..." caption="..." alt="..." /> for ALL images. Omit caption prop if there's no caption. When a caption contains double quotes, use single quotes for the prop value instead: caption='text with "quotes" in it'
• Make ALL URLs pointing to wasp.sh or wasp-lang.dev relative (e.g., https://wasp.sh/blog/... → /blog/..., https://wasp.sh/docs/... → /docs/..., https://wasp-lang.dev/docs/... → /docs/...). This applies to both markdown links and any other references throughout the entire post.
• Keep external URLs (GitHub, Twitter, etc.) as-is

Step 5: Verify with the user

Show a summary of what was created:

• File path
• Number of images downloaded and total size savings from WebP conversion
• Any decisions made (title choice, skipped sections, etc.)
• Remind user to review anchor links in TL;DR sections
