Total Recall is a memory system for Claude Code that provides persistent, curated memory across sessions. It implements a tiered architecture with daily logs for raw capture, registers for structured domain knowledge, working memory for essential context (auto-loaded every session), and archive for historical data. The core innovation is its write gate mechanism that evaluates whether information should be saved based on whether it changes future behavior, preventing memory bloat. The system includes automatic hooks for session context loading and pre-compaction flushing, a sophisticated ID-based metadata system for tracking memory entries, and maintenance routines for pressure-based cleanup. It's designed as both a plugin and standalone installation with comprehensive slash commands for all memory operations.
