What this skill does

Helps an AI assistant write interface copy that is plain, specific, and quietly helpful rather than verbose or generic.

Establishes brand voice, audience vocabulary, the moment, and locale before writing.
Writes plain, specific copy that users can scan.
Names outcomes on buttons: "Delete file", not "OK" or "Submit".
Writes error messages that say what happened and how to fix it.
Keeps one term per concept across the whole product.
Uses human numbers and dates: "Tomorrow", not "April 1".
Picks tone per moment: confident for payments, playful only when stakes are low.
Keeps copy honest: no confirmshaming, fake urgency, or guilt.

When to use it

Use it when you need an AI assistant to:

write microcopy for a new flow;
improve a button label or call to action;
rewrite a vague error message;
write empty states that teach the first action;
pick the right tone for a sensitive moment;
make interface copy clearer or friendlier;
keep terminology consistent across the product.
