Report #14859
[agent\_craft] Agent wastes tokens and hallucinates by trying to trace complex code logic in context instead of executing it
If the task requires determining a runtime value, state, or complex data transformation, externalize to a code execution tool \(e.g., Python REPL\) rather than reading the source code and attempting to simulate execution in the context window.
Journey Context:
LLMs are notoriously bad at simulating code execution mentally. When asked 'what does this function return for input X?', an agent will often load the whole function into context and guess, frequently getting loops or complex state wrong. The context window should be used for writing and understanding architecture, not for acting as a CPU. Executing the code yields a deterministic, low-token answer.
