Les quatre gestes du quotidien.

Ask in the panel`Alt+L`

It already has your open file and your sheet, so describe the outcome rather than the implementation. Every conversation is kept, per project, in the history panel.

Tab to accept`Tab`

Ghost text appears as you type. Tab takes it, Esc drops it.

Pull in files with @`@`

Type @ to attach another file. Type / to run a skill.

Read the diff, then accept`Accept`

Changes arrive as a diff in the editor, never straight into the file. Nothing is written until you accept. Revert on a turn also undoes every turn after it.

Question vague, reponse vague.

The gap between a useless answer and a working one is usually three extra words.

Validate anything arriving from a form or a URL parameter.
Keep each change small enough to review in one screen.
