Tool Output Summarization: Keep Context Small, Keep Decisions Sharp

Why raw outputs hurt reasoning

Raw outputs (HTML, long JSON, logs) are token-heavy and distracting. Summarization creates a “clean observation” layer that improves next-step decisions.

Summarize for decision-making, not for beauty

Good summaries include:

  • Key facts
  • Uncertainties
  • Next decision points
  • Evidence references (IDs, URLs)

Structured summaries

Use a small JSON format:

{"facts":[], "unknowns":[], "next":[], "evidence":[]}

Store summaries

Store the summary in memory/logs and keep the raw payload in storage for debugging.
