@atproto/lex quickly became part of my daily Bluesky workflow. It feels focused, fast, and polished in a way most side tools do not.
Uses it throughout the day for posting, reading, and lightweight workflow management.MP

The best part is how approachable it is. I understood the core value in minutes, and the details make it feel considered instead of rushed.
Especially helpful for developer tool workflows.
