## User Experience Research Assessment

**Review Date**: 2026-02-18
**Reviewer**: UX Research Agent
**Document**: TASK_ORCHESTRATION_MASTER_PLAN.md
**Overall Assessment**: **APPROVE WITH CHANGES**
**UX Rating**: **7.5/10**

## Executive Summary

The Task Orchestration Master Plan presents a compelling vision for natural language-powered task management across multi-repository ecosystems. The plan demonstrates strong understanding of developer workflows and leverages existing ecosystem components effectively. However, several **critical UX issues** must be addressed before implementation to ensure adoption and usability.

**Key Strengths**:
- Natural language task creation reduces cognitive load
- Semantic search addresses discoverability gaps
- Multi-interface approach (CLI, TUI, GUI, Web) accommodates different workflows
- Quality gate integration ensures developer-centric design

**Critical Issues**:
- CLI command discoverability is insufficient
- TUI design lacks modern UX patterns from existing research
- Error handling and recovery strategies are underdeveloped
- Onboarding and training gaps exist
- Accessibility considerations are missing

---

## 1. CLI UX Assessment

### 1.1 Command Structure & Discoverability

**Current Design**:
```bash
mhv task add "Fix auth bug in session-buddy by Friday"
mhv task list --status pending
mhv task find "authentication issues"
mhv task start 42
mhv task complete 42
```

**Issues**:

#### ❌ Issue 1: Command Palette Missing (CRITICAL)

**Severity**: P0 - Blocks discoverability

**Problem**:
The plan shows standard CLI commands but lacks the **command palette** pattern identified as high-impact in existing UX research (`/docs/archive/analysis/TUI_UI_INNOVATION_ANALYSIS.md`).

**Evidence from Existing Research**:
> "Command Palette (Ctrl+K style) - Impact: ⭐⭐⭐⭐⭐, Effort: ⭐⭐"

**Impact**:
- Users must memorize command syntax or read docs
- Contradicts "natural language" value proposition
- Creates friction for new users

**Recommended Fix**:
```bash
# Add command palette to CLI
mhv --help  # Show: Press Ctrl+K for command palette

# Implement fuzzy search
> <Ctrl+K>
> Command Palette: _
> 🔍 fix auth
>    add        Add new task
>    find       Find tasks by search
>    start      Start task execution
```

**Implementation Priority**: Phase 1 (Foundation)
**Effort**: 1-2 days (using prompt_toolkit or Textual)

---

#### ❌ Issue 2: No Command Shorthands (HIGH)

**Severity**: P1 - Reduces efficiency

**Problem**:
Commands are verbose compared to developer expectations from tools like Git, Docker, and existing Mahavishnu CLI patterns.

**Evidence**:
From UX assessment: "Alias provides shell-like convenience without shell overhead"

**Current**:
```bash
mahavishnu task add "Fix bug"
mahavishnu task list --status pending
mahavishnu task complete 42
```

**Recommended**:
```bash
# Full commands (for scripts)
mhv task add "Fix bug"
mhv task list --status pending

# Shorthands (for interactive use)
mhv t add "Fix bug"        # t = task
mhv t ls -s pending        # ls = list, -s = status
mhv t cmplt 42             # cmplt = complete

# Or following Git pattern
mhv task add "Fix bug"
mhv tasks --status pending  # Plural noun is shorter
mhv task 42 --complete      # Subcommand pattern
```

**Implementation Priority**: Phase 1
**Effort**: 1 day (add Typer aliases)

---

#### ⚠️ Issue 3: Natural Language Parser Uncertainty (MEDIUM)

**Severity**: P2 - Risk of user frustration

**Problem**:
The plan shows regex-based parser in Phase 1, LLM-based in Phase 8. This creates **uncertainty** about which features work when.

**Example**:
```bash
# Will this work in Phase 1?
mhv task add "Fix the thing that's broken in the API"
# Parser extracts: "thing" (what?), "API" (where?)
# User expectation: AI should understand context
```

**Recommended Fix**:

1. **Set Clear Expectations** in CLI output:
```bash
$ mhv task add "Fix the thing"
⚠️  Simple parser active: Be specific
   Try: "Fix bug in session-buddy by Friday"
   Tip: Advanced AI parsing available in Phase 8
```

2. **Provide Fallback to Manual Mode**:
```bash
# If parser is uncertain
$ mhv task add "Fix that thing" --interactive
? Repository: [session-buddy] _
? Type: [bug/feature/refactor] _
? Priority: [low/medium/high/critical] _
? Deadline: [optional] _
```

3. **Show Extracted Metadata for Confirmation**:
```bash
$ mhv task add "Fix auth bug by Friday"
✅ Created task #42: Fix auth bug
   Repository: session-buddy (inferred)
   Priority: HIGH (inferred)
   Deadline: 2025-02-21 (inferred)
   ⚠️  Is this correct? [Y/n]
```

**Implementation Priority**: Phase 1
**Effort**: 2-3 days

---

### 1.2 Output Design & Feedback

#### ✅ Strength: Rich Console Output

**Example from plan**:
```bash
✅ Created task #42: Fix authentication bug
   Repository: session-buddy
   Priority: HIGH
   Deadline: 2025-02-21
   ⚠️  Note: 3 similar tasks found
   🔮 Predicted duration: 4 hours (87% confidence)
```

**Assessment**: EXCELLENT
- Clear visual hierarchy
- Actionable insights
- Emoji status indicators (matches terminal conventions)

**Minor Recommendation**:
- Add hyperlinks to related tasks (OSC 8 protocol):
```bash
   🔗 Related: #41, #45
   🔗 View: https://github.com/user/repo/issues/42
```

---

#### ❌ Issue 4: Error Messages Lack Recovery Guidance (CRITICAL)

**Severity**: P0 - Blocks task completion

**Problem**:
The plan shows NO examples of error handling or recovery patterns.

**Example Scenarios** (not addressed):

```bash
# What happens when repository doesn't exist?
$ mhv task add "Fix bug in unknown-repo"
❌ Error: Repository not found
# Missing: "Did you mean...?", "Available repos: ..."

# What happens when worktree creation fails?
$ mhv task start 42
❌ Error: Worktree creation failed
# Missing: "Reason: ...", "Retry: ...", "Skip worktree: ..."

# What happens when quality gates fail?
$ mhv task complete 42
❌ Quality gates failed
   Tests: 15/18 passing
   Coverage: 62% (needs 80%)
# Missing: "Next steps: ...", "Override: ..."
```

**Recommended Fix**:

Adopt pattern from existing UX research:

```python
def show_error(message: str, solution: str, command: str = None):
    """Show error with actionable recovery"""
    console.print(f"[red]✗[/red] {message}")
    console.print(f"[dim]→ {solution}[/dim]")
    if command:
        console.print(f"[dim]→ Run: {command}[/dim]")
```

**Examples**:

```bash
# Repository not found
$ mhv task add "Fix bug in unknown-repo"
❌ Repository 'unknown-repo' not found
→ Available repositories:
   - session-buddy
   - mahavishnu
   - backend-api
→ Did you mean 'session-buddy'?
→ List all repos: mhv list-repos

# Worktree creation failed
$ mhv task start 42
❌ Worktree creation failed
→ Reason: Git worktree 'task-42-fix-auth-bug' already exists
→ Solution: Remove existing worktree first
→ Run: mhv worktree prune --name task-42-fix-auth-bug
→ Or: mhv task start 42 --skip-worktree

# Quality gates failed
$ mhv task complete 42
❌ Quality gates failed (2/4 passed)
   ✅ Tests: 18/18 passing
   ❌ Coverage: 62% (needs 80%)
   ✅ Security: 0 issues
   ❌ Type Safety: 3 errors
→ Next steps:
   1. Add tests for uncovered functions
   2. Fix type errors: mhv task show 42 --type-errors
→ Override anyway: mhv task complete 42 --force
→ Save for later: mhv task pause 42
```

**Implementation Priority**: Phase 1
**Effort**: 3-5 days (all error paths)

---

### 1.3 Interactive vs Scriptable

#### ✅ Strength: Dual-Mode Design

**Assessment**: The plan correctly supports both interactive and scripted usage.

**Interactive Mode** (Phase 2+):
```bash
mhv task  # Enter TUI
```

**Scriptable Mode** (Phase 1):
```bash
mhv task add "Fix bug" --repo session-buddy
```

**Recommendation**:
- Document all commands for CI/CD use
- Provide JSON output option:
```bash
mhv task list --format json
# For parsing in scripts
```

---

## 2. TUI Design Assessment

### 2.1 Framework Choice

#### ✅ Strength: Textual Framework

**Assessment**: EXCELLENT choice

**Evidence from Existing Research**:
> "Textual - ⭐⭐⭐⭐⭐ (Production), Rich widgets, Async/Event-driven, Medium learning curve - PRIMARY CHOICE"

**Rationale**:
- Modern async architecture (fits Mahavishnu)
- Rich widget ecosystem (DataTable, TreeView, etc.)
- CSS-like styling (familiar to web developers)
- Built-in testing (headless mode)
- Active development (10K+ GitHub stars)

---

### 2.2 TUI Layout & Navigation

#### ⚠️ Issue 5: TUI Layout Missing Key UX Patterns (HIGH)

**Severity**: P1 - Reduces discoverability

**Problem**:
The proposed TUI layout is functional but lacks **modern UX patterns** identified as high-impact in existing research.

**Current Design** (from plan):
```
┌────────────────────────────────────────────────────────────────┐
│  Mahavishnu Task Manager                          [All Tasks ▼]│
│  ┌────────────────────┐  ┌────────────────────────────────────┐│
│  │ 📋 Task List (23)  │  │ 🔍 Task Details                     ││
│  │                    │  │                                    ││
│  │ [ACTIVE]           │  │ Task #42: Fix auth bug              ││
│  │ ▶ Fix auth bug     │  │                                    ││

│  [n] New  [s] Start  [c] Complete  [d] Delete  [q] Quit          │
└──────────────────────────────────────────────────────────────────┘
```

**Missing Features** (from UX research):

1. **Command Palette** (⭐⭐⭐⭐⭐ impact)
   - Current: No search capability
   - Needed: Ctrl+K fuzzy search for all commands

2. **Contextual Help** (⭐⭐⭐⭐ impact)
   - Current: Static help screen
   - Needed: Hover tooltips, context-sensitive help

3. **Split Panes** (⭐⭐⭐⭐⭐ impact)
   - Current: Fixed layout
   - Needed: Resizable panels (e.g., `vim` splits)

4. **Tabbed Interface** (⭐⭐⭐⭐ impact)
   - Current: Single view
   - Needed: Tabs for Tasks, Workflows, Analytics

5. **Keyboard Shortcuts Display** (⭐⭐⭐⭐ impact)
   - Current: Footer shows basic shortcuts
   - Needed: Context-aware shortcuts (change per view)

**Recommended Enhanced Layout**:

```

```

**Key Improvements**:
1. Tabbed interface (switch views)
2. Command palette indicator (top-right)
3. Contextual shortcuts (bottom)
4. Split pane with resize (drag border)
5. Insights panel (bottom-left)

**Implementation Priority**: Phase 6 (TUI) - Week 1
**Effort**: 3-5 days

---

#### ❌ Issue 6: No Visual Workflow Builder (HIGH)

**Severity**: P1 - Misses strategic opportunity

**Problem**:
The plan mentions "visual workflow builder" in GUI/Web (Phase 7) but NOT in TUI (Phase 6).

**Evidence from UX Research**:
> "Visual Workflow Builder - Impact: ⭐⭐⭐⭐⭐, Effort: ⭐⭐⭐⭐"

**Why This Matters**:
- Developers live in the terminal
- Switching to GUI breaks flow
- TUI can do node-based workflows (TreeView)

**Recommended TUI Workflow Builder**:

```python
from textual.widgets import TreeView

class WorkflowBuilder(Vertical):
    """Node-based workflow editor in TUI"""

    def compose(self) -> ComposeResult:
        yield TreeView("Workflow")

    def on_mount(self) -> None:
        tree = self.query_one(TreeView)
        root = tree.root.add("Task #42 Workflow", expand=True)

        # Add nodes
        root.add_leaf("1. Setup: Create worktree")
        dev = root.add("2. Development", expand=True)
        dev.add_leaf("  2a. Write code")
        dev.add_leaf("  2b. Write tests")
        qa = root.add_leaf("3. Quality Gates")
        qa.add_leaf("  3a. Run tests")
        qa.add_leaf("  3b. Check coverage")
        root.add_leaf("4. Completion: Create PR")

    async def on_tree_node_selected(self, event):
        """Edit node on Enter"""
        # Show edit form
        pass
```

**Screen Layout**:
```

```

**Implementation Priority**: Phase 6 (TUI) - Week 2
**Effort**: 1 week

---

### 2.3 Real-Time Updates

#### ✅ Strength: WebSocket Integration

**Assessment**: EXCELLENT design

**Current Design** (from plan):
```python
# WebSocket integration for real-time updates
async def update_metrics(self):
    pools = await self.app.pool_manager.list_pools()
    # Update UI live
```

**Recommendation**:
- Show "Live" indicator when connected
- Handle disconnect gracefully:
```bash
📋 Task List (23) [🔴 Live]
# vs
📋 Task List (23) [⚠️ Disconnected - Retrying...]
```

---

## 3. GUI/Web Interface Assessment

### 3.1 Desktop App vs Web App

#### ✅ Strength: Dual Interface Strategy

**Assessment**: GOOD approach

**Desktop (Electron)**:
- Native notifications
- Menu bar integration (macOS)
- Offline capability

**Web (FastAPI + React)**:
- Mobile-responsive
- Real-time collaboration
- Lower distribution barrier

**Concern**: Electron app adds maintenance burden

**Alternative**: Progressive Web App (PWA)
- Single codebase (React/Next.js)
- Native-like features (notifications, offline)
- Installable from browser
- Auto-updates

**Recommendation**:
- Build **PWA** instead of Electron (Phase 7)
- Reduces maintenance from 2 codebases to 1
- Still provides native app experience

---

### 3.2 Mobile Responsiveness

#### ⚠️ Issue 7: Mobile UX Underdeveloped (MEDIUM)

**Severity**: P2 - Limits usability

**Problem**:
The plan shows mobile view but lacks **mobile-specific UX patterns**.

**Current Design** (from plan):
```
┌─────────────────────────────┐
│  ☰  Tasks             @les  │
│  [+ New Task]               │
│  🔴 Fix auth bug            │
│     [Start] [Complete]      │
└─────────────────────────────┘
```

**Missing**:
1. **Swipe gestures** (archive, complete)
2. **Pull-to-refresh**
3. **Bottom navigation** (easier for thumbs)
4. **Haptic feedback**
5. **Offline mode** (view tasks without network)

**Recommended Mobile UX**:

```javascript
// Swipe to complete
<ListItem
  onSwipeRight={() => completeTask(task.id)}
  onSwipeLeft={() => deleteTask(task.id)}
>
  <TaskItem task={task} />
</ListItem>

// Pull to refresh
<RefreshControl onRefresh={refreshTasks} />

// Bottom navigation
<BottomNavigation>
  <NavItem icon="list" label="Tasks" />
  <NavItem icon="chart" label="Analytics" />
  <NavItem icon="settings" label="Settings" />
</BottomNavigation>
```

**Implementation Priority**: Phase 7 (Web) - Week 2
**Effort**: 3-5 days

---

## 4. Onboarding & Training

### 4.1 First-Time User Experience

#### ❌ Issue 8: No Onboarding Flow (CRITICAL)

**Severity**: P0 - Blocks adoption

**Problem**:
The plan has NO onboarding, tutorials, or interactive guidance.

**Evidence from UX Research**:
> "Interactive Tutorials - Impact: ⭐⭐⭐⭐, Effort: ⭐⭐⭐"

**User Impact**:
```bash
# First-time user experience
$ mhv task add "Fix bug"
# What happens? No guidance, no examples, no help
# User must read 100-page manual
```

**Recommended Onboarding Flow**:

**1. First Run Detection**:
```bash
$ mhv task

**2. Interactive Tutorial** (TUI):
```python
class InteractiveTutorial:
    """Step-by-step guided onboarding"""

    async def run(self):
        # Step 1: Create task
        yield TutorialStep(
            title="Create Your First Task",
            instruction="Type: mhv task add 'Fix bug in session-buddy'",
            hint="Use natural language! Be specific about repo and deadline.",
            validate=self.check_task_created
        )

        # Step 2: List tasks
        yield TutorialStep(
            title="View Your Tasks",
            instruction="Type: mhv task list",
            hint="You can filter by status, priority, or repository",
            validate=self.check_task_listed
        )

        # Step 3: Start task
        yield TutorialStep(
            title="Start Working",
            instruction="Type: mhv task start 1",
            hint="This creates a worktree and opens your terminal",
            validate=self.check_task_started
        )
```

**3. Progressive Hints** (after tutorial):
```bash
# Show contextual hints based on user actions
$ mhv task add "Fix bug"
💡 Tip: You can be more specific!
   Try: "Fix bug in session-buddy by Friday, high priority"
   Press [?] for help, [Ctrl+K] for command palette

# After 3 tasks created
$ mhv task add "Fix bug"
💡 New feature unlocked!
   Try semantic search: mhv task find "authentication issues"
   Or view insights: mhv task insights 1
```

**Implementation Priority**: Phase 1 (Foundation)
**Effort**: 1 week

### 4.2 Documentation & Help

#### ⚠️ Issue 9: Help System Fragmented (MEDIUM)

**Severity**: P2 - Reduces self-service

**Problem**:
The plan shows help commands but doesn't specify **help discoverability**.

**Current**:
```bash
mhv task --help  # Show help for task commands
mhv task add --help  # Show help for add
```

**Missing**:
- Global help index (search all docs)
- Contextual help (show help relevant to current action)
- Example library (common patterns)

**Recommended Help System**:

```bash
# 1. Global help search
$ mhv help search "worktree"
📚 Found 3 results:
   1. Worktree Management (5 min read)
   2. Task Workflows > Worktree Integration (2 min read)
   3. Troubleshooting > Worktree Errors (3 min read)
   View: mhv help open 1

# 2. Contextual help
$ mhv task start 42 --help-context
📖 Starting a Task
   When you start a task:
   1. A worktree is created (git worktree)
   2. A terminal session is opened
   3. Baseline tests are run
   4. Task status changes to "in_progress"

   Related:
   - Worktrees: mhv worktree --help
   - Quality Gates: mhv task complete --help
   - Examples: mhv help examples task-start

# 3. Example library
$ mhv help examples
📚 Example Library:
   Daily Workflow:
     1. mhv task add "Fix bug by Friday"
     2. mhv task start 1
     3. # Work in worktree
     4. mhv task complete 1

   Multi-Repo Workflow:
     1. mhv task add "Update API, then frontend and docs"
     2. mhv task graph 1
     3. mhv task start 1
```

**Implementation Priority**: Phase 1
**Effort**: 3-5 days

---

## 5. Accessibility Assessment

### 5.1 Screen Reader Support

#### ❌ Issue 10: No Accessibility Considerations (CRITICAL)

**Severity**: P0 - Excludes users

**Problem**:
The plan has ZERO mention of accessibility, screen readers, or assistive technologies.

**Impact**:
- Developers with visual disabilities cannot use the system
- Violates inclusive design principles
- May have legal compliance implications (WCAG)

**Recommended Accessibility Features**:

**CLI Accessibility**:
```bash
# Screen reader friendly mode
$ mhv task list --accessibility
# Output:
Task 1: Fix authentication bug. Status: In progress. Priority: High.
Task 2: Update API. Status: Pending. Priority: Medium.
Task 3: Add tests. Status: Blocked. Priority: Low.

# Or use text-to-speech
$ mhv task list --speak
# Uses system TTS to announce tasks
```

**TUI Accessibility**:
```python
# Textual has accessibility support
from textual.widgets import DataTable

class AccessibleDataTable(DataTable):
    """Screen reader compatible table"""

    def on_mount(self):
        # Enable accessibility mode
        self.announce_to_screen_reader = True

        # Provide row descriptions
        self.announce("Task list loaded. 23 tasks total.")
```

**Web Accessibility**:
- ARIA labels on all interactive elements
- Keyboard navigation (not just mouse)
- High contrast mode support
- Screen reader testing (NVDA, JAWS)

**Implementation Priority**: Phase 1 (Foundation)
**Effort**: Ongoing (test with screen readers)

---

### 5.2 Color Blindness

#### ⚠️ Issue 11: Color-Only Status Indicators (MEDIUM)

**Severity**: P2 - Affects 8% of male population

**Problem**:
The plan uses emoji/color for status but lacks **alternative indicators**.

**Current**:
```
🔴 High priority
🟡 Medium priority
🟢 Low priority
```

**For Color-Blind Users** (red-green color blindness):
```
🔴 High priority → ❌ Cannot distinguish red
🟡 Medium priority → ⚠️ May look like red/green
🟢 Low priority → ❌ Cannot distinguish green
```

**Recommended Fix**:

**1. Add Text Labels**:
```bash
🔴 HIGH   Fix auth bug
🟡 MEDIUM Update API
🟢 LOW    Add tests
```

**2. Add Icon Indicators**:
```bash
🔴 ⬆️ HIGH   Fix auth bug        # Arrow up = high
🟡 ➡️ MEDIUM Update API          # Arrow right = medium
🟢 ⬇️ LOW    Add tests            # Arrow down = low
```

**3. Use Color Blind-Safe Palette**:
```python
# Use Okabe-Ito palette (color blind safe)
COLORS = {
    "HIGH": "#E69F00",      # Orange (visible to all)
    "MEDIUM": "#56B4E9",    # Sky blue
    "LOW": "#009E73",       # Bluish green
    "CRITICAL": "#D55E00",  # Vermillion
}
```

**Implementation Priority**: Phase 1
**Effort**: 1 day (add text labels, change palette)

---

## 6. Mental Model & Cognitive Load

### 6.1 Conceptual Model

#### ✅ Strength: Familiar Mental Models

**Assessment**: GOOD alignment with developer mental models

**Task Lifecycle**:
```
pending → in_progress → completed
```
**Matches**: Git workflow, Jira, GitHub Projects

**Worktree Integration**:
```
task → worktree → terminal → quality gates → complete
```
**Matches**: Existing development workflow

**Minor Issue**:
- "Orchestration" terminology may confuse new users
- Suggest: Use "task management" in docs, "orchestration" in code

---

### 6.2 Cognitive Load

#### ⚠️ Issue 12: Multi-Storage Complexity (MEDIUM)

**Severity**: P2 - Increases learning curve

**Problem**:
The plan uses **3 storage systems** (SQLite, Akosha, Session-Buddy), which creates cognitive load.

**User Impact**:
```bash
# User question: "Where is my task stored?"
# Answer: "Well, it's complicated..."
```

**Recommended Simplification**:

**Hide Complexity from Users**:
```bash
# User sees:
$ mhv task add "Fix bug"
✅ Task created

# User asks:
$ mhv task show 1 --storage
📊 Task Storage:
   Primary: SQLite (fast queries)
   Semantic: Akosha (searchable)
   Context: Session-Buddy (conversation history)

# Most users don't need to know this
```

**Developer Docs** (separate):
```markdown
## Storage Architecture
- SQLite: Primary store (structured data)
- Akosha: Semantic layer (embeddings, relationships)
- Session-Buddy: Context layer (conversation history)
```

**Implementation Priority**: Phase 2 (document in developer guide)
**Effort**: 1 day (docs only)

---

## 7. Error Handling & Recovery

### 7.1 Error Messages

**Already covered in Issue 4** (CLI Error Messages)

### 7.2 Undo/Redo

#### ❌ Issue 13: No Undo/Redo Capability (HIGH)

**Severity**: P1 - Risk of data loss

**Problem**:
The plan has NO undo/redo for destructive operations.

**User Impact**:
```bash
$ mhv task delete 42
# Oops! Wrong task. Can't undo.
```

**Recommended Fix**:

**1. Soft Delete**:
```bash
$ mhv task delete 42
✅ Task moved to archive (restore with --unarchive)
$ mhv task list --archived
# Show archived tasks
```

**2. Confirmation Prompt**:
```bash
$ mhv task delete 42
⚠️  Delete task #42: Fix auth bug?
   This will move the task to archive.
   [y/N]
```

**3. Undo Command**:
```bash
$ mhv task undo
# Undo last destructive action
```

**4. Time-Travel for Task State**:
```bash
$ mhv task history 42
# Show all state changes
2025-02-18 10:00  Created (pending)
2025-02-18 10:05  Started (in_progress)
2025-02-18 12:00  Completed
2025-02-18 12:05  Reopened (in_progress)

$ mhv task restore 42 --to-state 2025-02-18T10:00
# Restore to previous state
```

**Implementation Priority**: Phase 1 (soft delete), Phase 4 (history)
**Effort**: 2-3 days

---

## 8. Performance & Responsiveness

### 8.1 CLI Performance

#### ✅ Strength: Async Design

**Assessment**: GOOD performance foundation

**From Plan**:
```python
async def create_task(self, description: str) -> Task:
    # Non-blocking operations
```

**Recommendation**:
- Add progress indicators for long operations:
```bash
$ mhv task add "Fix bug"
⏳ Creating task...
   ⏳ Parsing description...
   ⏳ Creating worktree...
   ⏳ Running quality gates...
✅ Task created (3.2s)
```

---

### 8.2 TUI Performance

#### ⚠️ Issue 14: No Optimization Strategy (MEDIUM)

**Severity**: P2 - Risk of slow UI

**Problem**:
The plan doesn't address TUI performance optimization.

**Recommended Optimizations**:

**1. Lazy Loading**:
```python
# Don't load all 1000 tasks at once
async def load_tasks_paginated(self, page: int = 0, per_page: int = 50):
    # Load first 50, load more on scroll
    tasks = await self.store.list(limit=per_page, offset=page*per_page)
    return tasks
```

**2. Virtual Scrolling**:
```python
# Only render visible rows
from textual.widgets import DataTable
table = DataTable(virtual_scroll=True)  # Not actual API, but concept
```

**3. Debounced Search**:
```python
# Don't search on every keystroke
async def on_input_changed(self, event: Input.Changed):
    # Debounce 300ms
    await asyncio.sleep(0.3)
    await self.search_tasks(event.value)
```

**4. Caching**:
```python
# Cache frequently accessed data
from functools import lru_cache

@lru_cache(maxsize=100)
def get_task_cached(self, task_id: int):
    return self.store.get(task_id)
```

**Implementation Priority**: Phase 6 (TUI)
**Effort**: 2-3 days

---

## 9. Internationalization (i18n)

### 9.1 Language Support

#### ⚠️ Issue 15: English-Only Design (LOW)

**Severity**: P3 - Limits global adoption

**Problem**:
The plan assumes English-only natural language processing.

**Impact**:
- Non-English developers cannot use NL features
- Date/time parsing fails for non-English formats

**Recommended Fix**:

**1. Locale Detection**:
```python
import locale

# Detect user locale
user_locale = locale.getdefaultlocale()[0]  # e.g., 'en_US', 'de_DE'

# Load NLP patterns for locale
nlp_patterns = load_patterns(locale=user_locale)
```

**2. Multi-Language Date Parsing**:
```python
# English: "by Friday"
# German: "bis Freitag"
# Spanish: "para el viernes"

from dateparser import parse
# Supports 70+ languages
date = parse("vor 3 tagen", languages=['de'])  # German
```

**3. UI Translations**:
```python
# Use gettext for translations
import gettext
_ = gettext.gettext

print(_("Task created successfully"))
```

**Implementation Priority**: Phase 8 (Advanced Features)
**Effort**: 2-3 weeks (all languages)

---

## 10. Developer Experience (DX)

### 10.1 Plugin/Extension System

#### ✅ Strength: MCP Integration

**Assessment**: EXCELLENT extensibility

**From Plan**:
```python
# MCP server integration
await mcp.call_tool("create_task", {...})
```

**Recommendation**:
- Document plugin API
- Provide plugin examples
- Create plugin template

---

### 10.2 Testing & Debugging

#### ⚠️ Issue 16: No Debug Mode (MEDIUM)

**Severity**: P2 - Hinders troubleshooting

**Problem**:
The plan doesn't specify debug/verbose modes.

**Recommended Fix**:

```bash
# Verbose mode
$ mhv task add "Fix bug" --verbose
📝 DEBUG: Parsing input: "Fix bug"
📝 DEBUG: Detected repository: None (using default)
📝 DEBUG: Detected type: bug (keyword match)
📝 DEBUG: Detected deadline: None (not specified)
⚠️  Warning: No repository specified, using 'session-buddy'
✅ Task created

# Debug mode with stack traces
$ mhv task add "Fix bug" --debug
🐛 DEBUG MODE ENABLED
📝 Stack traces on error
📝 Logging to: /tmp/mahavishnu-debug.log
```

**Implementation Priority**: Phase 1
**Effort**: 1 day
