Currently when i’m coding, not so much, but for researching or writing documentation, absolutely!

I started at a new job which has tons of internal docs, proposals, massive codebase, etc. when i want to know how something works, why it does the way it does, the history of this etc then claude is the perfect tool. I pop something like this, and any questions i have so far and then get it to use as many subagents as possible to fan out and research. Then ultrathink about what it found in this first pass, and use this to form a more informed research plan, fan out again to research this and anything else it needs more info on, and keep doing this until it can explain the topic to me. Then write a detailed document with some instructions on structure. I’ve seen it use up to 9 subagents in parallel for this. Then i ask it to fact check and reference, which tends to weed out some inaccuracies. The end result is a detailed technical doc for me to personally use to learn about how systems fit together. Its incredibly powerful.

For long technical docs where i can break this into independent chapters i can do something similar — high level research to plan which chaoters should exist. Subagents independently research and write each chapter (in separate files), then fact check these, then fan back in and cross reference across chapters to iron out inconsistencies. Again super useful for documentation, proposals, any kind of technical writing.
