# Story 438: Slash command autocomplete in web UI text input

## User Story

As a user, I want to type `/` at the start of the text box and see a filtered list of available slash commands, so that I can discover and quickly invoke commands without memorizing them.

## Acceptance Criteria

- [ ] Typing `/` at position 0 in the ChatInput textarea shows a command picker overlay above the input
- [ ] The overlay lists all slash commands with name and description
- [ ] Typing further characters after `/` fuzzy-filters the list
- [ ] Arrow keys navigate the list, Tab/Enter selects, Escape dismisses
- [ ] Selecting a command inserts `/<command> ` into the input (with trailing space)
- [ ] Command list is a single shared source of truth used by both the picker and HelpOverlay
- [ ] The overlay follows the same visual style as the existing file picker (@-mention overlay)

## Out of Scope

- TBD
