Diagnose and fix Hypothesis (hypothes.is) annotation visibility — why two people in the same group see different annotation counts, why a class or study group can't see someone's notes, why highlights never show up for anyone else, and how to safely move "Only Me" annotations into a group or pull accidentally-public ones back out. Use this whenever someone mentions Hypothesis, hypothes.is, web annotations, annotation groups, highlights that aren't appearing, mismatched annotation counts ("I see 5, they see 149"), students who can't see the teacher's notes, or annotations that went public by mistake — including when they describe it as a broken integration, a sync issue, a caching problem, or a membership/permissions bug, because it is almost never any of those.

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.
