Memory System Overhaul

What

Complete restructuring of the persistent memory system with typed categories, frontmatter format, and two-step save process.

Details
  • Four memory types: user (preferences/role), feedback (corrections/guidance), project (ongoing work context), and reference (external system pointers)
  • Memories use markdown files with YAML frontmatter (name, description, type fields)
  • Two-step save: write the memory file, then add a pointer in the memory index
  • Clear guidance on what NOT to save (code patterns, git history, ephemeral details)
  • When users correct information stated from memory, the stored entry must be updated
  • CLAUDE_COWORK_MEMORY_PATH_OVERRIDE environment variable to customize the memory directory
Evidence

Memory system (search for "## Types of memory", "## What NOT to save in memory", "CLAUDE_COWORK_MEMORY_PATH_OVERRIDE")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
