## Houston 0.4.22

A release about choice and recovery. Switch the AI behind a chat without starting over, give each scheduled task its own brain, and get clearer prompts when a provider needs you to reconnect. Drop-in on top of 0.4.21, no breaking changes.

### Added

- **Switch the AI mid-conversation.** You can move a live chat to a different AI provider at any time without losing the thread. Houston carries your conversation over to the new provider: the full history when it fits, or a short summary (with your go-ahead) when it does not. Handy when one provider runs out of credit, or you just want a second opinion partway through.
- **Each scheduled task can pick its own AI.** Routines can now choose their own provider, model, and effort level instead of always inheriting the agent's default. Pin a faster, cheaper model for a routine check-in, or a higher-effort one for the heavy weekly job. Leave it untouched and it keeps following the agent.

### Fixed

- **Houston picks the AI you actually use.** Agents with no provider set used to fall back to Claude, which failed if you only use OpenAI. Houston now falls back to your last-used or only connected provider, so agents from the Store, scheduled tasks, and quick sends all start on the right AI.
- **A clear reconnect prompt for OpenAI.** When OpenAI ends your login session on their side, the chat showed a red border but no way to fix it, and any hint vanished on reload. Now you get the same inline reconnect button Claude already had, and it sticks around until you reconnect.
- **Clearer messages when Claude is rate-limited.** A Claude "too many requests" response used to show up as an unknown error with a "Report bug" button, sometimes doubled. It now reads correctly as a temporary rate limit, shown just once.
- **Your own message shows in the mission card.** Starting a task from a skill used to show a raw behind-the-scenes marker instead of what you wrote. The mission card now shows your message.
- **Tool steps no longer take over the chat.** A long list of an agent's tool steps could expand and crowd out the conversation. That panel is now capped, so the chat stays readable.

### Before you upgrade

- **Mac:** quit Houston before installing. macOS does not always replace a running app cleanly. If in doubt, remove `/Applications/Houston.app` and drag the new copy in.
- **Windows x64:** auto-update from 0.4.7 or later pulls you forward automatically. The MSI is still not OS-code-signed (SignPath integration still pending), so Windows SmartScreen may warn on a fresh install.
- **Windows ARM64:** there is no auto-update path from an emulated x64 install. Download the ARM64 MSI manually, uninstall the x64 build first, then install the ARM64 one.
