[FEATURE] Single-prompt model override

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, to use a different model for just one prompt, I need to run three commands:

1. /model haiku (switch from default)
2. Ask my prompt
3. /model opus (switch back to default)

This is cumbersome for quick questions where I want to use a lighter model (like Haiku) but keep Opus as my default.

Proposed Solution

Allow specifying the model for a single prompt without changing the session default. For example:

/model haiku my prompt here


This would:

• Execute the prompt with the specified model
• Not change the default model for subsequent prompts
• Return to the original model for the next interaction

Allow configurable aliases in settings.json that could bundle model + effort selections, making it easier to switch to predefined configurations for a single prompt.

Use Case Example

When using Opus as my default, I frequently want to ask quick clarifying questions or simple tasks that don't need complex reasoning.

Having to manually switch models and back is friction that a single-command override would eliminate.
