Bug Report

Feature area: TUI @ reference picker and / slash command overlay — live update

Severity: Medium — overlays are only populated on submit, making them useless as interactive pickers

What was tested

src/cleveragents/tui/app.py — event handler registration and overlay update logic.

Expected behavior (from spec)

Both the @ reference picker overlay and the / slash command overlay should update live as the user types:

When the user types @, the reference picker should appear and filter candidates in real time
When the user types /, the slash command overlay should appear and filter commands in real time
As the user continues typing after @ or /, the overlay should narrow its suggestions

Actual behavior

app.py defines only two event handlers:

on_mount(self) — initialises overlays with empty/full data at startup
on_input_submitted(self, event) — fires only when the user presses Enter

There is no on_input_changed handler. The overlays are never updated while the user is typing. Specifically:

The slash command overlay is set once on mount with all 70 commands and never updated again
The reference picker overlay is only updated in on_input_submitted — after the user has already submitted the message

# app.py — only these two handlers exist
def on_mount(self) -> None:
    # Sets slash overlay once with all commands
    slash.set_commands("", slash_command_specs())
    # Sets ref picker with empty suggestions
    ref_picker.set_suggestions("", [])

def on_input_submitted(self, event) -> None:
    # Only updates ref picker AFTER submit — too late
    if "@" in text:
        ref_picker.set_suggestions(text, suggestions(...))

Code locations

src/cleveragents/tui/app.py lines 123–141 — on_mount (no live update)
src/cleveragents/tui/app.py lines 168–210 — on_input_submitted (only fires on Enter)
Missing: on_input_changed handler that would call slash.set_commands(query, ...) and ref_picker.set_suggestions(query, ...) as the user types

Steps to reproduce

Open the TUI
Type /ses — the slash overlay shows all 70 commands, not filtered to session:*
Type @proj — no reference picker appears while typing
Press Enter with @proj in the prompt — only now does the reference picker update

Impact

The interactive autocomplete UX is completely absent. Users see a static list of all 70 commands regardless of what they type, and the @ reference picker is invisible until after message submission.

Implementation Attempt — Tier 3: sonnet — Success

Added the missing on_input_changed event handler to src/cleveragents/tui/app.py.

What was done

Added on_input_changed handler to _TextualCleverAgentsTuiApp that:
- When text starts with /, filters slash commands by the query after the slash in real time
- When text contains @, extracts the token after the last @ and updates the reference picker with matching suggestions
- Otherwise resets both overlays to their default (unfiltered) state
Added 5 BDD scenarios to features/tui_app_coverage.feature covering all branches of the new handler
Added step definitions to features/steps/tui_app_coverage_steps.py
