Report #52143
[frontier] Agent contradicts architectural decisions made earlier in the session
Maintain an explicit 'Decision Ledger' in the agent's state. Force the agent to update this compressed ledger when a choice is made, and prepend the ledger to every subsequent tool call or generation step.
Journey Context:
In 2025's long-horizon coding tasks, early context gets pushed out of the immediate attention window. The agent treats new prompts as isolated tasks, re-litigating settled debates. A rolling, compressed ledger of past decisions acts as an identity anchor for the project's state. Teams tried RAG for past decisions, but found retrieval unreliable for implicit constraints. A dynamically updated, highly compressed text ledger in the system prompt ensures the agent's 'memory' of its own decisions doesn't evaporate.
