claude-msync

Sync Claude Code memories to Claude clients (claude.ai / Claude App).

Claude Code stores memories as local markdown files, but these are not accessible from Claude clients. claude-msync scans memory files across all projects, generates a structured summary via Claude's memory migration prompt locally, and copies it to your clipboard — ready to paste into a Claude client as a Project Prompt.

Install

npx claude-msync             # run directly
npm install -g claude-msync  # or install globally as `msync`

Usage

msync                    # Interactive select → choose model → stream summary → clipboard
msync --list             # List all memories
msync --all              # Select all, skip picker
msync --export out.md    # Export to file
msync --model opus       # Specify model (sonnet/opus/haiku)

How it works

1. Scans all Claude Code auto-generated memory locations (see below)
2. Interactive multi-select picker (all selected by default)
3. Calls local Claude CLI with a memory migration prompt to deduplicate and categorize
4. Copies result to clipboard
5. Go to claude.ai/settings/capabilities, click Start Import, paste the result to sync

Scanned locations

| Source | Location | |--------|----------| | Project auto memory | ~/.claude/projects/*/memory/*.md (including MEMORY.md index) | | Subagent memory (user scope) | ~/.claude/agent-memory/*/*.md | | Subagent memory (project scope) | <project>/.claude/agent-memory/*/*.md | | Subagent memory (local scope) | <project>/.claude/agent-memory-local/*/*.md | | Custom memory directory | Via autoMemoryDirectory in ~/.claude/settings.json |

Only auto-generated memory is included. User-authored files (CLAUDE.md, AGENTS.md, etc.) are never scanned.

**Instructions**

[2026-04-01] - When encountering model ID issues, check proxy config and connectivity first
[2026-04-07] - Apply code changes directly instead of describing what to change
