# Task Management UI Implementation Plan

## Overview

This document outlines the implementation of two key improvements to the task
management system:

1. **Safe Internal Tool Annotation System** - Mark task tools as never needing
   user approval
2. **Custom Task Tool Renderers** - Replace generic JSON output with clean,
   readable UI components

## Context Reading

Before starting, read these documents to understand the codebase:

- `docs/architecture.md` - Overall system architecture
- `docs/development.md` - Development setup and workflow
- `docs/design/tools.md` - Tool system design and patterns
- `docs/coding.md` - Code style and quality standards

## Current System Analysis

### Tool Approval Flow

- **Location**: `src/tools/policy-wrapper.ts`
- **How it works**: Global policy wrapper checks CLI options, then delegates to
  interface callback
- **Current annotations**: `readOnlyHint`, `destructiveHint`, `idempotentHint`,
  `openWorldHint`
- **Decision flow**: Session cache → disabled checks → guardrails → auto-approve
  → tool hints → user prompt

### Tool Renderer System

- **Location**: `src/interfaces/terminal/components/events/tool-renderers/`
- **Pattern**: Each tool has optional custom renderer (e.g.,
  `BashToolRenderer.tsx`)
- **Discovery**: `getToolRenderer.ts` uses naming convention to find renderers
- **Fallback**: `GenericToolRenderer.tsx` shows raw JSON with `[GENERIC]`
  indicator
- **Base Component**: All renderers use `TimelineEntry` component with status
  indicators

### Task Management Tools

- **Location**: `src/tools/implementations/task-manager/tools.ts`
- **Tools**: `TaskCreateTool`, `TaskListTool`, `TaskViewTool`, `TaskUpdateTool`,
  `TaskAddNoteTool`, `TaskCompleteTool`
- **Output**: Currently uses generic JSON rendering
- **Formatter**: `formatter.ts` has CLI-friendly formatting utilities

## Implementation Tasks

### Task 1: Add Safe Internal Tool Annotation System ✅ COMPLETED

**Goal**: Enable tools to bypass all approval prompts

**Files modified**:

- `src/tools/types.ts` - Added `safeInternal` to `ToolAnnotations` interface
- `src/tools/policy-wrapper.ts` - Added safe internal check at step 1.5
- `src/tools/implementations/task-manager/tools.ts` - Added annotation to all 6
  task tools
- `src/tools/__tests__/policy-wrapper.test.ts` - Added comprehensive test
  coverage

**TDD Steps completed**:

1. ✅ Wrote failing test that verifies `safeInternal` annotation bypasses
   approval
2. ✅ Added `safeInternal?: boolean` to `ToolAnnotations` interface
3. ✅ Ran test to confirm it fails
4. ✅ Added safe internal check to policy wrapper (step 1.5 in decision flow)
5. ✅ Ran test to confirm it passes
6. ✅ Added `safeInternal: true` to all task management tool classes

**Test coverage**: All tests passing, including new safe internal test

**Implementation completed**:

```typescript
// In src/tools/types.ts
export interface ToolAnnotations {
  title?: string;
  readOnlyHint?: boolean;
  destructiveHint?: boolean;
  idempotentHint?: boolean;
  openWorldHint?: boolean;
  safeInternal?: boolean; // NEW: Always approved, never needs user consent
}

// In src/tools/policy-wrapper.ts (added after step 1, before step 2)
// 1.5. Check if tool is marked as safe internal
const tool = toolExecutor.getTool(toolName);
if (tool?.annotations?.safeInternal === true) {
  return ApprovalDecision.ALLOW_ONCE;
}

// In each task tool class
annotations = {
  safeInternal: true,
};
```

npm run build
npm run lace -- --help

# Create and manipulate tasks to verify rendering
```

**Commit**: `test: add integration tests for task tool renderers`

## Technical Requirements

### Dependencies

- React and Ink for UI components
- `TimelineEntry` component for consistent styling
- `ink-testing-library` for component testing
- Existing task management system

### Code Quality

- Follow existing patterns in `BashToolRenderer.tsx`
- Use TypeScript strict mode
- Handle errors gracefully with fallback to generic renderer
- Maintain consistent spacing and color coding
- Follow TDD approach strictly

### Testing Strategy

- Unit tests for each renderer component
- Integration tests for tool discovery
- Error handling tests for malformed data
- Visual regression tests for UI consistency
- Test with real task operations

### Performance Considerations

- Avoid heavy computations in render methods
- Use React.memo for expensive components
- Minimize re-renders with proper dependencies
- Handle large task lists efficiently

## Success Criteria

1. **Safe Internal Tools**: All task management tools execute without approval
   prompts
2. **Custom Renderers**: All task tools show custom UI instead of generic JSON
3. **Consistent Design**: All renderers follow the same visual patterns
4. **Error Handling**: Graceful degradation when renderers fail
5. **Test Coverage**: >90% code coverage for all new components
6. **Performance**: No noticeable impact on terminal responsiveness

## Rollback Plan

If issues arise:

1. Disable custom renderers by removing them from `getToolRenderer.ts`
2. Revert to generic JSON rendering
3. Fix issues and re-enable gradually
4. Safe internal annotation can be disabled via CLI option

## Future Enhancements

1. **Interactive Elements**: Add cursor navigation for task lists
2. **Export Capabilities**: Allow exporting rendered output
3. **Theme Support**: Add color scheme customization
4. **Accessibility**: Screen reader support and keyboard navigation
5. **Performance**: Virtualization for large task lists
