Prefs change defaults for the active session.
Use them when you want repeated CLI behavior without repeating request fields.

Set prefs:
session prefs set <name> <value> [<name> <value>...]

Example:
session prefs set inspect.graph.hubs false inspect.graph.leaves false

Show prefs:
session prefs get [prefix] [--all]

By default, get shows session overrides.
--all includes defaults.
prefix filters keys.

boolean = true|false
N = integer

Available prefs:
inspect.code.maxNonEmptyLines N
inspect.usages.maxLocations N
inspect.usages.maxCodeBlocks N
inspect.members.maxItems N
inspect.members.all boolean
inspect.graph.hubs boolean
inspect.graph.entrypoints boolean
inspect.graph.leaves boolean
inspect.graph.edges boolean
inspect.graph.symbols boolean
inspect.graph.symbolUsage boolean

Use prefs to reduce repeated request fields and avoid unnecessary output.

If graph output is too noisy:
session prefs set inspect.graph.hubs false inspect.graph.leaves false

Change prefs while working. Turn details back on when you need them.
