Don't automatically add ASD-STE100 to your agents instructions
I read quite a lot of advice from people recommending adding ASD-STE100 to your Claude/Agents md instruction file.
My counter advice is don't do that. Because ASD-STE100 cannot represent domain language and so you will lose specific domain concepts defined by some words.
I showed here https://allaboutcoding.ghinda.com/explain-to-me-in-simple-technical-english/ that a better approach is to use "Simple Technical English" which will preserve domain concepts as they are without trying to re-explain them.
For me this is a better alternative and I ran some experiments comparing them.
See the entire experiment here at my repo about llm-experiments and you can run it yourself via Apple Containers or can ask your agent to make a version that works with your machine configuration.
I gave it Ruby code as domain content but you can set up your own experiment using your own codebase or documents.
This way you can make sure that you decide based on your specific case and business domain. For some people AST-STE100 might work, for other people might not.
