# Execute Spec Tasks with TDD

Execute implementation tasks from spec using Kent Beck's Test-Driven Development methodology.

## Arguments: {{args}}

## Current Specs
Available specs: !{bash -c 'ls .kiro/specs/ 2>/dev/null || echo "No specs found"'}

## Instructions

### Help Mode (--help)
If arguments contain "--help", show usage:
```
/kiro:spec-impl [feature-name] <task-numbers>

Examples:
  /kiro:spec-impl auth-system 1.1            # Execute task 1.1
  /kiro:spec-impl auth-system 1,2,3          # Execute tasks 1, 2, 3
  /kiro:spec-impl auth-system --all          # Execute all pending tasks
```

### Pre-Execution Validation
Feature name: **{{args}}** (first argument will be parsed as feature name)

Validate required files exist:
Validate required files exist for feature **[feature-name]**:
- Requirements: `.kiro/specs/[feature-name]/requirements.md`
- Design: `.kiro/specs/[feature-name]/design.md`  
- Tasks: `.kiro/specs/[feature-name]/tasks.md`
- Metadata: `.kiro/specs/[feature-name]/spec.json`

### Project Context Loading
**Load all required content before execution:**

**Core Steering:**
- Structure: @.kiro/steering/structure.md
- Tech Stack: @.kiro/steering/tech.md  
- Product: @.kiro/steering/product.md

**Custom Steering:**
- Additional `*.md` files in `.kiro/steering/` (excluding structure.md, tech.md, product.md)

Core Steering and Custom Steering files will provide overall project context.

**Spec Documents:**
Feature name directory: **{{args}}** (first argument)
- Metadata: @.kiro/specs/[feature-name]/spec.json
- Requirements: `.kiro/specs/[feature-name]/requirements.md`
- Design: `.kiro/specs/[feature-name]/design.md`
- Tasks: `.kiro/specs/[feature-name]/tasks.md`


### Task Execution
1. **Parse feature name and task numbers** from arguments
2. **Load all context** (steering + spec documents)
3. **Execute selected tasks** using TDD methodology

### TDD Implementation
For each selected task:

1. **RED**: Write failing tests first
2. **GREEN**: Write minimal code to pass tests  
3. **REFACTOR**: Clean up and improve code structure
4. **Verify**: 
   - All tests pass
   - No regressions in existing tests
   - Code quality and test coverage maintained
5. **Mark Complete**: Update checkbox from `- [ ]` to `- [x]` in tasks.md

**Note**: Follow Kent Beck's TDD methodology strictly, implementing only the specific task requirements.

## Implementation Notes

- **Feature**: Use `$1` for feature name
- **Tasks**: Use `$2` for specific task numbers (optional)
- **Validation**: Check all required spec files exist
- **TDD Focus**: Always write tests before implementation
- **Task Tracking**: Update checkboxes in tasks.md as completed
