About Sphinx
I make sphinxstack, an independent library of skills for AI agents. I use the name Sphinx online. This is why I built the library and who I hope it helps.
Why I made it
Young people leaving school or college are often given four instructions at once: learn AI, build projects, make a portfolio, and find a job. The advice is reasonable, but it usually arrives without an order of work or a standard for what counts as finished.
AI makes the gap more visible. Opening an agent is easy. Knowing what work is worth doing, how to direct it, how to check the result, and how to turn it into evidence is harder. A chat can produce an answer. It does not automatically supply a method you can inspect, improve, and use again.
I kept seeing versions of the same problem in people trying to enter technology: they had access to capable tools, but no working system for using them. sphinxstack is my attempt to make that system public and practical.
Why the site is built around skills
Getting a job is not one task. It is a chain of tasks: choose something worth building, plan it, build it, check it, publish it, explain it, reach the right people, and record the evidence on a resume. sphinxstack treats each part as a skill.
A prompt names what you want. A skill carries the method: what to inspect, which questions to ask, what not to break, and what proves the work is finished. Because the skill is a plain file, you can read it before trusting it, change it after a failure, and take it to the next agent you use.
Who it is for
The library is mainly for people near the beginning of working life: students, recent graduates, self-taught builders, and anyone trying to find their first real foothold in technology. It assumes they know AI exists and want to use it. It does not assume they already know the unwritten process around good work.
It is also for the friend, teacher, manager, or older sibling trying to help. A skill is easier to hand over than a long explanation, and easier for the recipient to question or adapt.
What success looks like
A successful visit should end somewhere outside this website: with a deployed project, a cleaned dataset, a sent application, a useful conversation, or a resume line supported by work another person can inspect. The skills are not credentials. The artifacts and the judgment behind them are the evidence.
The library is free to use. There is no required account, installation, or course. Take one file, use it on a real problem, and keep the parts that help.
About Sphinx
On X, I am @protosphinx. I care about people learning to build, technology widening access to useful work, and making practical knowledge available to people who did not start with insider instructions. sphinxstack is the focused, working part of that motivation.
I also care deeply about manufacturing and the systems that turn designs into real products: materials, machines, suppliers, logistics, quality, and the people who keep them working. That interest and sphinxstack share the same concern: turning knowledge into repeatable capability that more people can use.
