One person,one standard.

Why this exists

Writing a skill takes an afternoon. Making one that fires on the words you actually type, does not assume tools you do not have, leaves room in the context window for your real work, and still behaves after Claude Code ships a new version takes considerably longer. That second part is the same work for everyone who needs it, and doing it once is the whole idea.

What we will not do

There is no marketplace here and there are no other sellers, so nothing has to be graded on a curve. That means a few things can stay true:

• No number we did not measure. Every trigger accuracy on this site comes from a written eval suite that ships public with the skill, and carries the date it was run. A skill with no number says so.
• No skill ships without a clean-machine test. A fresh container, installed the way you would install it. The errors from that run become the troubleshooting table.
• No fake proof. No logo wall, no testimonial nobody gave, no customer count. When there are real ones, they will be real.
• No copy protection theatre. Claude reads a skill as plain text, so anything on your disk is copyable and pretending otherwise would be insulting. What you are buying is that it keeps working.

How a skill gets here

1. Pick a job people repeat, and work out what a reliable skill for it has to do.
2. Write the eval suite first, so the before number is honest rather than reconstructed afterwards.
3. Build it, then harden it: the trigger description, the assumed tools, the context budget, the error handling, the docs.
4. Install it into a fresh container and run the documented examples without fixing anything.
5. Publish the number, the suite, and what it needs to run.

Where the code comes from

We write it. Open-source projects get read the way you read any prior art, for an approach or a failure mode, and what ships is ours. Where a skill genuinely does build on someone else's published work, that is said on its page and their licence ships in the package. Leaving that out to look more original is not a positioning decision, it is a lie, and it is the one thing here that could not be walked back.

What is not built yet

Most of it. The catalogue is a plan, no skill has been measured, and payment is not switched on. That is why nothing on this site claims otherwise and why every listing says what state it is in. If you want one of them, saying so moves it up the queue.
