# Switch Default Instance

Switch the default test instance used by all recipe skills. This updates `default_instance` in `settings.toml`. Domain is computed dynamically via `get_test_instance.py`, so no global find-and-replace is needed.

The target instance is: $ARGUMENTS

Read and follow the instructions in `.claude/commands/includes/logging.md`.

## Steps

1. **Validate the argument** — `$ARGUMENTS` must be either `b1cc` or `t1cc`. If it's empty or something else, tell the user the valid options and stop.

2. **Check the current instance** — run:
   ```bash
   python3 scripts/switch_default_instance.py
   ```
   This shows the current default and available instances. If the current default already matches the requested instance, tell the user and stop (no work needed).

3. **Run the switch script**:
   ```bash
   python3 scripts/switch_default_instance.py $ARGUMENTS
   ```

4. **Verify** — run `python3 scripts/get_test_instance.py` and confirm the SERVER uses the new instance's domain suffix.

5. **Summarise** — tell the user which instance is now active and what the test server domain is (`<instance>.commoninternet.net`).
