Report #99802

[agent\_craft] Tool outputs pile up in the transcript and consume tokens the agent no longer needs.

After the agent has acted on a tool result, replace the bulky tool\_result block with a compact placeholder \(e.g. file path, status, timestamp\) while keeping the tool\_use record. If the data is needed again, the agent can re-call the tool.

Journey Context:
Tool results are often re-fetchable \(file reads, API responses\). Keeping the raw payload in every subsequent turn burns context budget for no benefit. Clearing is one of the safest compaction moves because the record of the action remains and the data can be regenerated on demand. Anthropic launched this as a first-class platform feature.
