Anthropic published a new feature called Skills and on the surface it sounds like a simple plugin of some sort. What it actually does is JIT context injection with increasing levels of information added as needed:

It uses YAML frontmatter for token efficiency and has the following anatomy:

*   Level 1: Metadata (always loaded) < 100 Tokens
    
*   Level 2: Instructions (loaded when triggered) < 5000 Tokens
    
*   Level 3: Resources and code (loaded as needed) (∞)!

Some people will consider this a proprietary approach but I have used heavily to allow for larger protocols but seeing Anthropic standardise is great validation of the concept. You can find an excerpt of my [AGENTS.md](http://AGENTS.md) that uses this approach [here](https://gist.github.com/numman-ali/c97fa2ae47d71c53f3a5c955fe9ec609)

Very excited to see more of this "Context Engineering" in the coming months!
