 ## Edit a Model
 
-Open model input file in your editor, or update via stdin in non-interactive
-mode.
+**Recommended:** Use `swamp model get <name> --json` to get the file path, then
+edit directly with the Edit tool, then validate with
+`swamp model validate <name> --json`. Never modify the `id` field.
 
-```bash
-# Interactive: opens in editor
-swamp model edit my-echo
-swamp model edit my-echo --resource  # Edit resource file instead
-
-# Non-interactive: update from stdin
-cat updated-model.yaml | swamp model edit my-echo --json
-
-# With here-doc (agent-friendly)
-swamp model edit my-echo --json <<EOF
-id: existing-uuid
-name: my-echo
-version: 1
-attributes:
-  message: "Updated message"
-EOF

-Without arguments in interactive mode, shows a search interface to select a
-model.
+- Interactive: `swamp model edit my-echo` (opens in system editor)
