Plan

⚠️ CRITICAL RULES - READ FIRST

1. DETECT MODE: Determine if input is an existing task reference or a new requirement description

   • If input looks like story-user-profile Task 1 or standalone-fix-login Task 2: MODE A
   • If input is a new requirement (e.g., "Fix login button hover"): MODE B

2. MODE A - Enhance Existing Task:

   • Read the task file from docs/reference/frontend/tasks/
   • User must specify task number (e.g., "Task 1", "Task 2")
   • Add or update the "Implementation Steps" section for that specific task
   • Keep all other sections intact
   • Save back to the same file

3. MODE B - Create Standalone Task File:

   • Analyze the requirement - is it simple (1 task) or complex (multiple tasks)?
   • If complex, break into multiple tasks (like task-breakdown does)
   • Use filename: standalone-{requirement-name}.md (kebab-case)
   • Save to docs/reference/frontend/tasks/
   • File format: same as story-based (multiple task sections)

4. READ CONSTRAINTS FIRST:

   • Must read docs/reference/frontend/design-system.md for design tokens
   • Must read docs/reference/frontend/constraints.md for tech stack
   • If task references a design, read from docs/reference/frontend/designs/

Language Configuration

Before generating any content, check aico.json in project root for language field to determine the output language. If not set, default to English.

MODE A: Enhance Existing Task

Process

1. Read task file: Get file from docs/reference/frontend/tasks/{filename}.md (story-_ or standalone-_)
2. Extract specific task: Find the task section by number (e.g., "Task 1", "Task 2")
3. Read related files (if referenced): Load design from docs/reference/frontend/designs/
4. Read design system: Load docs/reference/frontend/design-system.md for design tokens
5. Read constraints: Load docs/reference/frontend/constraints.md
6. Break into atomic steps:
   • Start with file creation/setup
   • One section/feature per step
   • Include verification for each step
   • Do NOT include commit step (that happens during execution)
7. Keep steps atomic: One action per step
8. Update task section: Add/replace "Implementation Steps" in the specific task
9. Present summary: Show what was added

Example

# Input: User runs /frontend.plan story-user-profile Task 2

# Output:
✓ Read file: docs/reference/frontend/tasks/story-user-profile.md
✓ Found Task 2: Implement Header Section
✓ Added 4 implementation steps

Steps added:
1. Create header component file
2. Implement header layout
3. Add responsive styles
4. Add unit tests

Task ready for implementation. Use /frontend.implement to execute.

MODE B: Create Standalone Task File

Process

1. Analyze requirement:

   • Is this a simple task (single responsibility) or complex (multiple steps)?
   • If complex, break down into multiple independent tasks

2. Ask user for details (optional):

   • Auto-generate task name from description
   • Ask for confirmation

3. Read constraints:

   • Read design system and technical constraints
   • If user mentions a component, check existing code

4. Generate task file (unified format):

   • File header with metadata
   • If simple: 1 task section with detailed steps
   • If complex: Multiple task sections (Task 1, Task 2, etc.)
   • Each task has: Description, Context, AC, Scope, Implementation Steps
   • Progress section at end

5. Save task file: Write to docs/reference/frontend/tasks/standalone-{name}.md

6. Present summary: Show created file and next steps

Example - Simple Requirement

# Input: User runs /frontend.plan "Fix login button hover state"

# Output:
✓ Created standalone task: standalone-fix-login-button-hover.md

File contains:
- 1 task: Fix Button Hover
- 3 implementation steps
- Test verification included

Next: Use /frontend.implement standalone-fix-login-button-hover Task 1

Example - Complex Requirement

# Input: User runs /frontend.plan "Add user profile page with avatar, bio, and settings"

# Output:
✓ Created standalone task: standalone-user-profile-page.md

File contains:
- Task 1: Setup Profile Page Component
- Task 2: Implement Avatar Section
- Task 3: Implement Bio Section
- Task 4: Implement Settings Section
- Task 5: Add Tests

Total: 5 tasks

Next: Use /frontend.implement standalone-user-profile-page Task 1

Implementation Steps Format

Both modes use the same step format:

## Implementation Steps

### Step 1: [Action]

**Files**:

- Create: `src/components/[Name].tsx`
- Modify: `src/pages/[Page].tsx:L10-L20`

**Action**:
[Exact code or action to take]

**Verify**:

```bash
[verification command]
```

Expected: [expected output]

Step 2: [Next Action]

...

## Step Granularity

Each step = ONE atomic action:

| Good Steps | Bad Steps |
|------------|-----------|
| Create component file with imports | Create component with all logic |
| Add component skeleton (empty return) | Implement entire component |
| Implement single section | Implement all sections |
| Write one test case | Write all tests |

## Step Types

### Setup Step
```markdown
**Files**: Create: `src/components/ProfileCard.tsx`
**Action**: Create file with basic structure
**Verify**: `npx tsc --noEmit` → No errors

Implementation Step

**Files**: Modify: `src/components/ProfileCard.tsx:L8-L10`
**Action**: Implement header section with Avatar and name
**Verify**: `npm run dev` → Component renders correctly

Test Step

**Files**: Create: `src/components/__tests__/ProfileCard.test.tsx`
**Action**: Write unit test for profile name rendering
**Verify**: `npm test ProfileCard` → 1 test passed

Standalone Task File Template

For MODE B, see Task File Template for complete structure.

Use the same format as story-based tasks, just with:

• Filename: standalone-{requirement-name}.md
• Header: # Standalone Tasks: [Requirement Name]
• No > **Story**: ... line

Note: For simple requirements, file may contain only 1 task. For complex requirements, break into multiple tasks.

Key Rules

• ALWAYS include verification command for each step
• MUST keep steps to 2-5 minutes of work
• MUST save to docs/reference/frontend/tasks/ directory
• NEVER combine multiple actions into one step
• Do NOT include commit step in plan (commits happen during execution)
• MODE A: Preserve all existing content, only add/update steps
• MODE B: Generate complete, self-contained task file

Common Mistakes

• ❌ Steps too large → ✅ One action per step
• ❌ Skip verification → ✅ Every step has verify command
• ❌ Vague actions → ✅ Include exact code
• ❌ Not saving to file → ✅ Always save task file
• ❌ Including commit in steps → ✅ Commits happen during execution, not planning
• ❌ MODE A: Overwriting existing content → ✅ Only update Implementation Steps section
• ❌ MODE B: Missing metadata → ✅ Include all template sections
