Use Emacs introspection functions to inspect commands and variables. Distinguish symbol existence, function binding, interactive command status, default values, and buffer-local values.
When checking key bindings, inspect the active keymaps in the relevant buffer.
Do not guess the representation of unfamiliar variables or complex values. Inspect the value's type and shape with a purpose-built helper or describe-variable before extracting fields. If an operation reports Wrong type argument, inspect type-of next instead of retrying with another guessed representation.
