+`profile:recommend` ranks installed Ollama models for `latency`, `balanced`, or `coding`, and `profile:auto` can persist the recommendation directly.
+If no profile exists yet, `dev:profile` now uses the same goal-aware defaults when picking the initial model.
+
+Use `--provider ollama` when you want a local-only path. Auto mode falls back to OpenAI when no viable local chat model is installed.
+Goal-based Ollama selection only recommends among models that are already installed and reachable from Ollama.
+
+Use `profile:codex` or `--provider codex` when you want the ChatGPT Codex backend.
+
 `dev:openai`, `dev:ollama`, and `dev:codex` run `doctor:runtime` first and only launch the app if checks pass.
 For `dev:ollama`, make sure Ollama is running locally before launch.
