Report #23176

[synthesis] Agent context window fills up with verbose tool logs causing amnesia of the original goal

Implement a summarization or truncation step for tool outputs. Keep the first N lines and last M lines of stdout/stderr, or use a secondary LLM to summarize the output before injecting it back into the main agent's context.

Journey Context:
When running shell commands or reading large files, agents often dump the entire output into the context. This pushes the original task instructions out of the active attention window, leading to goal amnesia where the agent starts doing irrelevant things. The tradeoff is losing fine-grained details vs. maintaining strategic coherence. Summarization preserves the signal while discarding the noise.
