# runtime/list-defs
List definitions in a child runtime's current namespace. Faster than `runtime/eval "[info/defs]"` — avoids the source-string round-trip.
## Syntax
[runtime/list-defs $name]
## Parameters
- `$name` — child runtime name
## Examples
[runtime/list-defs "worker"]
## Returns
`%{ :value :output :error }` (same shape as `runtime/eval`).
## See Also
`runtime/eval`, `runtime/list`
