Slash command tab completion

[anentropic]

Describe the feature or problem you'd like to solve

It would be nice to have tab completion for slash command params

Proposed solution

Screen.Recording.2026-01-12.at.17.57.28.mov

e.g. here... there is no hint for what the set of possible model names is

hitting tab seems to toggle back to the /mcp command for some reason, instead of providing a completion of the /model command I already selected

Example prompts or workflows

Here I typed in "Claude Opus 4.5" :

It didn't like that, so after getting it wrong once it gave me the list of acceptable values (it'd be nice to see their cost multipliers here too!)

these should be provided as a tab completion or drop down menu in the first place though

or I'd love to be able to just click on the current model name over on the RHS and change it from there:
