DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

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.
