+Each agent becomes a project-scoped `.md` SubAgent file in `.qwen/agents/`.
+
+From a fresh clone, generate the Qwen files first:
+
+```bash
+./scripts/convert.sh --tool qwen
+```
+
+Then install them from your project root:
+
+```bash
+cd /your/project && /path/to/agency-agents/scripts/install.sh --tool qwen
+```
