Toasted golden, schmeared with insight. Top of the rack.
Summary
OpenAI is quietly implementing skills support in both ChatGPT and Codex CLI, following Anthropic's skills mechanism introduced in October. Skills are simple folders containing Markdown files and optional resources that allow LLM tools to navigate and read from filesystems. The article discusses how this implementation works, the potential for skills to become a standard format for LLM capabilities, and the implications for developers and users.

· 3 pulledA skill is just a folder with a Markdown file and some optional extra resources and scripts, so any LLM tool with the ability to navigate and read from a filesystem should be capable of using them.
It turns out OpenAI are doing exactly that, with skills support quietly showing up in both their Codex CLI tool and now also in ChatGPT itself.
One of the things that most excited me about Anthropic's new Skills mechanism back in October is how easy it looked for other platforms to implement.
