[architecture] Stale tool outputs and API responses polluting working memory

Ephemeralize tool outputs. Only persist the derived insight or extracted variables from a tool call into long-term memory, discarding the raw JSON payload immediately after processing.

Journey Context:
When an agent calls an API, the raw response \(often massive JSON\) gets appended to the context or saved as a memory. This quickly fills the context window, pushing out the actual system prompt or user request. The tradeoff is auditability \(keeping raw logs\) vs. context efficiency. The right call is to treat raw tool outputs as ephemeral scratchpad data; extract the semantic value, and discard the raw payload to maintain a high signal-to-noise ratio in the context.
