what is skills fr?

skills is a personal library of reusable instructions, called agent skills, that teach an AI coding assistant how to plan, build, and check its own work across many kinds of projects. It is meant to work with several different AI coding tools, including Claude Code, Codex, opencode, Cursor, and many others that support the same skill format. You add it to a project with a single command, and you can either pull in every skill or pick individual ones and copy them into your tool's own skills folder. The core idea behind the collection is that a big goal should be broken down not just into a list of tasks, but into pieces that can each be checked and confirmed correct on their own, before moving on to the next piece. One skill interviews you about what you want built and writes that plan out as a specification file. Another skill then works through that plan step by step, building each piece and reviewing it before continuing, and updating the plan itself if the work reveals that the original plan no longer fits. Other skills in the set handle more specific jobs: reviewing a code change for leftover mess or unclear naming, writing tests that check real behavior rather than superficial details, writing documentation that explains ideas instead of just describing code, and comparing screenshots to judge whether a visual change actually looks right. There are also skills for keeping the skill library itself in good shape, such as one for writing new skills well and another for testing whether a skill actually works as intended before relying on it. A separate small group of skills focuses on graphics work, specifically building and debugging WebGPU renderer code. This project is best suited for developers who already use an AI coding assistant regularly and want a more structured, checked way of directing it on larger features, rather than giving one-off instructions and hoping the result is correct. It is released under the MIT license, which allows free use, including commercially.
