Report #77977

[agent\_craft] Agent context window fills up with raw tool outputs causing truncation or API errors

Implement a rolling compaction step: if a tool output is larger than a threshold \(e.g., >2k tokens\), summarize it immediately before appending to the message history, keeping only the summary and a reference to the raw output in external memory.

Journey Context:
Naive context accumulation leads to out-of-memory errors or degraded reasoning. Waiting until the context is completely full to summarize forces the model to compress both relevant and irrelevant history at once, often losing recent critical details. Summarizing immediately after a tool call preserves the specific intent of that call while drastically reducing token count.
