Claude Code + MemorySync

Overview

Install the MemorySync plugin from its marketplace and Claude Code remembers: lifecycle hooks persist every prompt and reply the moment they happen and inject relevant memories at session start, per prompt, and again after context compaction. Memory is auto-scoped to the git repository (worktree-aware), the full MemorySync MCP server and memory skills come bundled, and every hook exits 0 on every failure — memory being down can never break a session. Cross-platform Node hooks: Windows, macOS and Linux natively. The same plugin works in Claude Cowork cloud sessions via repo-declared settings.

Setup status and requirements

Permissions

A MemorySync API key with read and write scopes (or OAuth through the bundled MCP server).

• Per-repo project scoping from the git remote, worktree-aware

• Session-safe by contract: every hook exits 0 on every failure
• Bundled MemorySync MCP server (API key or OAuth) + docs server
• /memorysync:status, /memorysync:remember, /memorysync:recall
