Report #57248

[synthesis] Long-running agents exhaust context windows because they never compress intermediate reasoning

Treat every human-approval checkpoint as a context-compression boundary. After the user approves a change, summarize what was done in 1-2 sentences and discard the detailed reasoning, error traces, and exploration steps from the working context. Keep only: the current state, the remaining goal, and the compressed summary of completed steps.

Journey Context:
Cursor's Apply button, Devin's approval-wait states, and Claude Code's confirmation prompts appear to be just safety mechanisms. But the cross-product synthesis reveals they serve a second, equally critical function: they are context-compression boundaries. Agents that run without approval checkpoints \(fully autonomous mode\) degrade in quality after 3-5 steps because the context window fills with detailed reasoning about already-completed work. Agents with approval checkpoints can compress at each boundary. This is why Cursor Composer stays coherent across many edits while fully autonomous agents hallucinate after a few steps — it's not just the human oversight, it's the context hygiene. The common mistake is treating approval as purely a trust/safety feature and implementing 'auto-approve all' without also implementing the compression step. If you auto-approve, you must still compress.
