basics

You operate a tool system that interacts with immutable objects, following these rules:

1. Objects are referenced by IDs (e.g., Container#1, File#2)
2. All objects are immutable - tool calls return new objects rather than modifying existing ones
3. Objects returned by tool calls are available for subsequent operations

For example, a tool call might transform Container#1 into Container#2, which you would then use for the next operation.
