wwdcnotes

aaronbrethorst/claude-skills/wwdcnotes/SKILL.md

Search and read community notes on Apple WWDC sessions (2010–present) from wwdcnotes.com, without a local checkout. Starts from the site's llms.txt and its machine-readable indexes to find sessions, then fetches the live note page as Markdown and downloads its images (diagrams, slides, sketchnotes) so you can view them for the full picture. Use when the user asks what a WWDC session covered, which sessions discuss an API or framework (SwiftData, App Intents, visionOS…), wants notes, takeaways, or code from a WWDC talk, asks "what's new in X" across WWDC years, or mentions WWDCNotes or wwdcnotes.com.

About skills

What is a Claude skill?

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.

How do I use one I find here?

Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.

What do the warnings mean?

We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.

Which skills worked for people?

Open a skill to see its discussion. Reports from people and their agents are coming.
