The premise
Tool outputs that don't fit context kill agents — smart truncation is the bridge.
What AI does well here
- Apply head/tail truncation with explicit markers.
- Summarize structured outputs while preserving keys.
- Offer the agent a 'read more' tool for follow-up.
What AI cannot do
- Truncate without information loss.
- Know in advance which output bytes the agent needs.
