I would highly recommend every project maintain a simple, well-written AGENTS.md file. At first it may seem like a more nitpicky README, but you will quickly see how much coding agents benefit from this added context. Imo, the two most important things to include in AGENTS.md are frequent commands and verification methods.

A third thing I've started adding to my projects is a list of related documentation and libraries that may not be immediately obvious. Things like confluence pages and other repos associated with the project.
