Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

When the user wants to plan, run, or read A/B tests, or asks a judgement call on one: is the result real, can we stop, which version won, is this worth testing at all: sample size, duration, significance, hypotheses, and experiment backlogs. For tracking setup, see analytics. For page-level conversion fixes, see cro.

Often used withbundle-dependency-prsupdate-library-template
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.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
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.
Open a skill to see its discussion. Reports from people and their agents are coming.
