SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill turns a pasted URL into a well-structured bookmark entry by automatically fetching basic page metadata and saving it to your persistent Bookmarks vault.

Core Features & Use Cases

  • One-step URL capture: paste a link and have it saved immediately to Bookmarks.md in a consistent format.
  • Automatic page metadata: fetches the target page to infer the bookmark name and a short description.
  • Smart categorization: assigns the best ## (and optional ###) category based on page content, without prompting the user.
  • Duplicate and existing-summary checks: prevents re-adding an already-saved URL and links to any prior summary note found in your vault.
  • Recategorize/move support: lets you move an existing bookmark to a new category while refreshing the Bookmarks metadata.

Quick Start

Use /bookmark https://example.com to save that URL to Bookmarks.md with an inferred name, description, and category.

FAQPage Schema
How do I save a URL to a markdown vault with automatic categorization?▼

To save a URL to a markdown vault, paste the link and the system fetches web metadata, infers a category, and appends the entry to your Bookmarks.md file. This captures the page title and description instantly without manual sorting.

Can I prevent duplicate bookmarks when adding new links?▼

Yes, duplicate bookmark prevention checks existing entries via grep before saving. If the URL already exists in your markdown vault, the system avoids re-adding it and links to any prior summary notes found for that page.

How does web metadata extraction work for bookmarking pages?▼

Web metadata extraction fetches the target page content to automatically infer the bookmark name and a short description. It uses this inferred data to structure the entry properly within your knowledge base.

What is the best way to reorganize saved bookmarks into new categories?▼

The best way to reorganize saved bookmarks is to use the recategorize support, which moves an existing bookmark to a new category while refreshing the page metadata. This updates your markdown vault structure dynamically without manual text editing.

Do I need to manually assign categories when capturing a URL?▼

No, you do not need to manually assign categories when capturing a URL. The system applies smart categorization by inferring the best heading levels directly from the fetched page content.

What happens if I try to bookmark a page I already summarized before?▼

If you try to bookmark a page you already summarized, the system detects the duplicate URL and prevents a redundant entry. It then links the bookmark to your existing summary notes within the vault.
