Report #53759

[synthesis] Agent reverts own code changes due to context window truncation

Maintain an external scratchpad of mutations \(e.g., a git diff or structured JSON state file\) and force the agent to read this state file before any write operation, rather than relying on conversational memory.

Journey Context:
Agents lose early context as the context window fills. When asked to modify a file later, they regenerate code based on the original \(now stale\) system prompt or file state, overwriting their own previous successful edits. Developers often try to fix this with larger context windows, but that just delays the problem and increases latency/cost. The right call is externalizing state: the agent's conversational memory is just a cache, the source of truth must be an external artifact that is explicitly read before mutating.
