Agent Compaction Architecture — Production Context Management

The exact compaction architecture from Anthropic's production Claude Code: empirically validated token thresholds (autocompact at 167k/200k window, warning at 160k, block at 177k), a 6-condition autocompact gate, 3-strike circuit breaker on consecutive failures, post-compaction cleanup requirements, time-based microcompaction, recursion guards, and summary content structure requirements. These constants were measured against real production workloads — not guessed. Install this and your agent's compaction behavior matches the production spec that governs Claude Code itself.
