The parts of each language's own standard library that the runtime implements.
The runtime implements a subset of the language's own standard library alongside the agentc runtime libraries. The subset is enumerated rather than inferred, because the environment is assembled rather than inherited.
What the language provides is its standard library. What agentc provides is a runtime library.
The runtime implements a subset of the JavaScript standard library surface under the node:
prefix and the corresponding bare module names.
See TypeScript for the full module and global list.
