Report #75199

[frontier] In iterative coding sessions, the agent's own previous outputs become the dominant training signal, creating an 'echo chamber' where style and constraint adherence drift toward the agent's own statistical preferences rather than the original instructions

Implement 'Contextual Reset with Distilled Memory'—every 10-15 turns, perform a 'soft reset' where the raw history is replaced by a compressed 'memory' generated by the agent itself that explicitly includes: \(1\) the original constraints, \(2\) key decisions made, and \(3\) current code state—effectively simulating a fresh session with a 'sticky note' summary

Journey Context:
This is the 'Context Window Pollution' problem. As agents iterate, they see their own code/style more than the original prompt. This is similar to how 'Chain of Thought' can drift if not grounded. Raw truncation loses critical constraints. MemGPT-style virtual memory helps, but for short-term role switches, explicit checkpointing is lighter than full OS-style paging. Distilled memory \(similar to 'summarization for context compression'\) preserves the semantic content while removing the 'echo' of the agent's own voice. This prevents the statistical drift where the model falls into patterns from its own previous outputs. It's distinct from simple summarization because it explicitly re-injects the original constraints, treating them as non-compressible while compressing the execution history.
