Report #63616
[agent\_craft] Verbose tool outputs push critical agent reasoning out of the context window
Cap tool stdout/stderr to a fixed token limit \(e.g., 2000 tokens\) at the execution layer, appending a '... truncated' marker, before returning to the agent context.
Journey Context:
A single massive stack trace or directory listing can consume thousands of tokens, instantly causing context overflow and pushing the system prompt out of the attention window. Agents rarely need the entire raw output; they need the signal. Aggressive truncation at the tool layer preserves the context window for the agent's chain-of-thought.
