 ### Embedding Model
 
+Search covers skills installed for every agent in the project, deduplicated. Restrict it with `--agents`:
+
+```bash
+skilld search "routing" --agents claude-code
+skilld search "routing" --agents claude-code,codex
+```
+
 `skilld search` is powered by a local embedding model. It runs offline through transformers.js. It needs no API key or network traffic after the first download. Pick one under **Embedding model** in `skilld config`:
