+#### Auto-commit and Auto-review
+
+When `autoCommit` is enabled (default), a follow-up agent session is spawned
+after each task to stage and commit uncommitted changes. When `autoReview` is
+enabled, a second follow-up session reviews the latest commit against the task
+description. Both options can be overridden at loop startup via a selection
+prompt.
+
+`commitModel` and `reviewModel` accept `<provider>/<model>` strings (e.g.
+`anthropic/claude-sonnet-4`) resolved via the model registry. When empty, the
+task's model is inherited. `implModel` sets the model for task implementation
+in sequential mode (overridden by `execution.models` round-robin in parallel
+mode).
