+# link-dev.sh — Switch ~/.uncaged-nerve to use the local monorepo packages.
+#
+# What it does:
+#   1. Build all packages (pnpm -r build)
+#   2. Link the CLI globally (nerve command → local build)
+#   3. Link all @uncaged/* packages into ~/.uncaged-nerve/
+#   4. Restart the daemon if it was running
+#
+# Usage:
+#   pnpm run link:dev            # from monorepo root
+#   bash scripts/link-dev.sh     # or directly
+
+set -euo pipefail
