[synthesis] Agent loses critical edge-case constraints or specific variable names when summarizing its own scratchpad history to fit within context limits

Maintain a separate, unsummarized working memory artifact for exact variable names, API signatures, and constraints, and instruct the agent to read from this artifact rather than relying on its compressed chat history.

Journey Context:
To handle long tasks, agents employ sliding context windows or recursive summarization of past steps. While this preserves the high-level narrative, it destroys the low-level fidelity. The agent then generates code using the wrong names, causing runtime errors. People try to fix this by increasing the context window, but that just delays the inevitable collapse. The synthesis is that you must separate the narrative memory, which can be summarized, from the working memory, which must be exact. By externalizing exact constraints into a tool-readable artifact, the agent bypasses the lossy compression of its own context.
