Report #90515

[architecture] Agent reasoning degrades because the context window is clogged with large, outdated tool outputs

Implement a transient scratchpad memory with explicit summarize and clear actions after the agent extracts the necessary information from a tool response.

Journey Context:
Agents often append tool outputs directly to the ongoing context. A single file read or API response can consume thousands of tokens. Once the agent extracts the few facts it needs, the raw output becomes pollution. A scratchpad allows the agent to explicitly clean up its working memory, trading the safety of raw data visibility for focused, cost-effective reasoning over long trajectories.
