Report #13712

[architecture] Agent hallucinates or repeats itself because old, irrelevant instructions or outputs are still in the context window

Implement context window curation via rolling summaries. Periodically summarize the middle/oldest parts of the conversation and replace them with the summary, keeping the system prompt and most recent turns intact.

Journey Context:
Just truncating the top of the context window loses the system prompt or early task definitions. Truncating the bottom loses recent actions. A rolling summary preserves the semantic intent of the early conversation while freeing up token space, preventing old context from polluting new answers.
