Baml Plugin
Two describe-first skills sharing the same content — the typed, expression-oriented language plus the LLM DSL that desugars into it. `core` discovers each name as needed; `overview` leads with `baml describe baml` to dump the whole stdlib first. Both name the few fatal traps and defer to `baml describe` for everything else rather than guessing. Auto-triggers when Claude opens a .baml file or is asked how to install / use BAML.
