+When storing repository-specific context, scope it to the project by passing a
+`project` slug to `add_memory`. Derive the slug the same way the plugin does, so
+memories align across clients: take the repo's git remote URL path
+(`owner/repo`, minus host and `.git`) — or the working-directory name if there's
+no remote — lowercase it, and replace every run of non-alphanumeric characters
+with a single `-` (e.g. `https://github.com/aristoapp/membase-plugin-mcp.git`
+→ `aristoapp-membase-plugin-mcp`). If you can't determine a slug, omit `project`
+rather than guessing. On the Claude Code plugin only, the `membase://project`
+resource returns this already-resolved slug; other clients (remote MCP) do not
+expose it, so don't depend on reading it.
