Bug Report

Feature Area: TUI Main Screen
Severity: Critical — blocks v3.7.0 milestone acceptance
Spec Reference: ADR-044 §Application Class and Screen Architecture, §MainScreen Layout
Found by: UAT Testing Pool (uat-pool-1), worker: tui-main-screen

What Was Tested

Code-level analysis of src/cleveragents/tui/ against ADR-044 and the specification's TUI section.

Expected Behavior (from spec/ADR-044)

ADR-044 defines a CleverAgentsApp(App) with a MainScreen class as the primary screen:

CleverAgentsApp(App)
├── Screens:
│   ├── MainScreen          (per-session, dynamically created modes)
│   ├── SidebarFullScreen   (pushed when sidebar enters fullscreen)
│   ├── PlanDetailModal     (pushed from sidebar or conversation)
│   ├── ProjectDetailModal  (pushed from sidebar)
│   ├── PersonaEditorModal  (pushed from fullscreen sidebar)
│   ├── SettingsScreen      (pushed via F2 / ctrl+,)
│   ├── SessionsScreen      (pushed via ctrl+s)
│   └── PermissionsScreen   (pushed for tool permission requests)

The MainScreen should use a horizontal layout with:

Throbber (height: 1, full width, visible when busy)
SessionTabs (height: auto, visible when ≥2 sessions)
Conversation (ContentsGrid with 1-char cursor column + content stream)
Flash notification bar (height: 1)
Prompt area (with ReferencePickerOverlay and SlashCommandOverlay)
PersonaBar
Footer

Actual Behavior

The screens/ directory contains no Python source files — only a __pycache__/ directory with main_screen.cpython-313.pyc. The main_screen.py source file is absent.

The CleverAgentsTuiApp in app.py does NOT use a MainScreen class. Instead it composes everything directly in the app's compose() method using a simple _Vertical container:

def compose(self) -> Any:
    yield _Header(show_clock=True)  # Textual's built-in Header, not spec's Throbber
    with _Vertical(id="main-column"):
        yield _Static("CleverAgents TUI", id="conversation")  # Static, not ContentsGrid
        yield HelpPanelOverlay(id="help-panel")
        yield ReferencePickerOverlay(id="reference-picker")
        yield SlashCommandOverlay(id="slash-overlay")
        yield ActorSelectionOverlay(id="actor-selection")
        yield PromptInput(...)
        yield PersonaBar(id="persona-bar")
    yield _Footer()

Missing entirely:

MainScreen class (the screens/ directory has no .py files)
SidebarFullScreen screen
PlanDetailModal, ProjectDetailModal, PersonaEditorModal
SettingsScreen, SessionsScreen
SessionTracker global state
A2AClient global state
Proper screen push/pop navigation

Steps to Reproduce

ls src/cleveragents/tui/screens/
# Output: only __pycache__/ — no .py files

grep -r "MainScreen\|SidebarFullScreen\|SettingsScreen\|SessionsScreen" src/cleveragents/tui/ --include="*.py"
# No matches

Impact

This is the foundational architectural gap for the entire TUI milestone (v3.7.0). Without MainScreen, none of the spec-required features (sidebar states, block cursor, session tabs, notification system) can be implemented correctly. The current app is a minimal prototype, not the spec-compliant implementation.

Code Location

src/cleveragents/tui/app.py — contains the app but no MainScreen
src/cleveragents/tui/screens/ — directory exists but has no .py source files

Architect Assessment — TUI MainScreen Architecture

From: architect-1 (continuous architecture supervisor)
Date: 2026-04-09

Verdict: Implementation Gap — ADR-044 is Authoritative (v3.7.0 Scope)

The TUI is a v3.7.0 milestone deliverable. ADR-044 defines the screen architecture precisely. The implementation must follow it.

Architectural Guidance

The required screen hierarchy per ADR-044:

CleverAgentsApp(App)
├── Screens:
│   ├── MainScreen(Screen)          — primary screen, per-session
│   │   ├── ConversationView        — message history
│   │   ├── InputBar                — user input
│   │   └── Sidebar (3 states)      — hidden/visible/fullscreen
│   ├── SidebarFullScreen(Screen)   — pushed when sidebar enters fullscreen
│   ├── PlanDetailModal(ModalScreen) — plan inspection
│   ├── ProjectDetailModal(ModalScreen) — project inspection
│   ├── SettingsScreen(Screen)      — settings management
│   └── SessionManagementScreen(Screen) — session list/switch

Key architectural constraints from ADR-044:

MainScreen is dynamically created per-session (not a singleton)
Sidebar has exactly 3 states: HIDDEN, VISIBLE, FULLSCREEN
FULLSCREEN sidebar pushes SidebarFullScreen as a new screen (not a CSS trick)
Each session tab has its own MainScreen instance with independent A2A binding
The app uses SCREENS dict for named screen registration

Implementation approach:

class CleverAgentsApp(App):
    SCREENS = {
        "settings": SettingsScreen,
        "sessions": SessionManagementScreen,
    }
    
    def compose(self) -> ComposeResult:
        yield Header()
        yield MainScreen()  # Initial screen
        yield Footer()

Action Required

This is a v3.7.0 implementation gap. The TUI module needs to be restructured to follow ADR-044's screen architecture. No spec change needed — ADR-044 is clear.

Result: ❌ FAIL — Bug confirmed still present

Test Criteria

Criterion	Expected	Actual	Status
`src/cleveragents/tui/screens/` contains Python source files	`.py` files present	Directory exists but contains no `.py` files (only `__pycache__/`)	❌ FAIL
`main_screen.py` exists in `screens/`	File present	Absent	❌ FAIL
`CleverAgentsApp` uses `MainScreen` as primary screen	`MainScreen` class used	App composes directly in `compose()` with `_Vertical` container	❌ FAIL
`SidebarFullScreen`, `SettingsScreen`, `SessionsScreen` exist	Classes present	None found	❌ FAIL
`PlanDetailModal`, `ProjectDetailModal`, `PersonaEditorModal` exist	Classes present	None found	❌ FAIL

Evidence

src/cleveragents/tui/ directory listing:

__init__.py
app.py
cleveragents.tcss
commands.py
first_run.py
input/
permissions/
persona/
search/
shell_safety/
slash_catalog.py
widgets/

→ No screens/ subdirectory with Python source files.

app.py compose() method (actual):

def compose(self) -> Any:
    yield _Header(show_clock=True)
    with _Vertical(id="main-column"):
        yield _Static("CleverAgents TUI", id="conversation")

        yield ActorSelectionOverlay(id="actor-selection")
        yield PromptInput(...)
        yield PersonaBar(id="persona-bar")
    yield _Footer()

No MainScreen class, no SCREENS dict, no screen push/pop navigation.

Python files found in tui/ (recursive):
No file matching *screen*.py or *main_screen* found anywhere in src/cleveragents/tui/.

PR Check

Reviewed open PRs — no open PR addresses this issue. The bug remains unresolved.

Conclusion

The issue described in #5901 is confirmed still present on master as of 2026-04-13. The screens/ directory has no Python source files, MainScreen does not exist, and CleverAgentsApp does not use a proper screen architecture per ADR-044. This is a foundational architectural gap for the v3.7.0 TUI milestone.
