    • resultText

      public String resultText()
      Returns the tool execution result as text. It is a result() that is serialized into JSON string. The text is calculated lazily on first access and then cached.

      Thread-safety: In rare concurrent scenarios, the supplier may be invoked multiple times, but only one result will be cached. Suppliers should be idempotent and side-effect free.

      Virtual thread friendly: Uses lock-free atomic operations that do not pin carrier threads.
