Plan mode is where Claude works out a plan before making changes. The error for a bad `plansDirectory` now says the folder must be inside your project and, outside Windows, must not contain a backslash. A related check now looks for backslashes on every system, not only outside Windows.\n\n**Why**\n\nIf your `plansDirectory` path contains a backslash, Claude Code may now refuse it. Use forward slashes to avoid this.\n\n- Area: Plan Mode\n- Names: `plansDirectory`\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: yes"}
