Report #60805

[agent\_craft] Agent waits until context is 100% full before summarizing, causing API truncation or failure

Trigger compaction/summarization when context reaches 60-70% of the window limit, ensuring there is enough room for the model to process the summary and continue the task.

Journey Context:
Late compaction is a race condition. If you hit the limit, the API will truncate your prompt, often cutting off the latest user message or tool output. Early compaction guarantees a smooth degradation into a summary rather than a hard crash or loss of the most recent context.
