+### CLI Naming Convention
+
+Prefer proper subcommands over hyphenated command names:
+- **Preferred:** `parallel-cc templates list`, `parallel-cc templates show <name>`
+- **Avoid:** `parallel-cc templates-list`, `parallel-cc templates-show <name>`
+
+Use hyphens only when it makes sense semantically (e.g., `sandbox-run` as a single action) or to maintain backward compatibility with existing commands.
