Claude Code Memory 2.0 (AutoDream)

A three-layer memory system in Claude Code: normal session chat, Auto Memory (a memory.md file that stores per-project facts and preferences injected into every new session), and AutoDream. AutoDream runs a background sub-agent periodically that consolidates, prunes, and refreshes memory files — modelled explicitly on human sleep. Activated via /memory, runs via /dream or on a time/session interval, and only touches memory files (never code). Reduces repetition, bloat, and context rot across long-lived projects.

Key points

• Three layers: session chat, Auto Memory (persistent memory.md), AutoDream (background cleanup)
• AutoDream runs a sub-agent that consolidates, prunes, and rewrites memory files
• Triggered by interval (hours) or session count — runs in background with a 'dreaming' status
• Only touches memory files (.md), never code or scripts
• Explicitly modelled on how humans consolidate memory during sleep
• Activated globally across projects via /memory interface
• Shows diff of added entries and removed sections after each dream
• Jack Roberts describes a complementary manual architecture for Claude/Codex-style work: stable identity instructions, per-project operating manuals, and long-term Pinecone or Obsidian archives ^[src-059].
• Roberts's emphasis is cross-app memory rather than only Claude Code internals: the outcome of a conversation should not depend on one chat history if the important context has been written into files or indexes ^[src-059].
• In the Hermes Agent OS demo, Roberts extends Claude Code memory outward: Hermes can ask what the Claude/Codex-style operating system knows, read overnight reflections, and surface active work context through Telegram ^[src-079].
