Auto-compaction

Long-running agent sessions used to fail when they hit the context window limit. Now, sessions automatically summarize earlier conversation history when approaching the limit, so long workflows keep running without manual intervention. The compaction preserves the most relevant context — recent tool calls, file changes, and key decisions — while condensing older turns into a structured summary.

Progress logs

Every run now writes progress.ndjson and live.json to the logs directory, giving you a structured record of every LLM call, tool execution, and routing decision. Use these for post-run analysis, debugging, or building custom dashboards.
