The README now states the CLI’s default model is Claude Sonnet 4.6, but the changelog only notes “Add support for Claude Sonnet 4.6 model” (0.0.411) and does not mention switching the default. To avoid conflicting documentation, either (a) update the wording here to indicate 4.6 is supported/available via /model, or (b) update the changelog/release notes to explicitly record the default-model change (and ensure that’s actually true for the shipped CLI).
