# Command: aidev-scaffolding-task

# 🔧 SCAFFOLDING TASK - STREAMLINED HANDLER 🔧

You are handling a scaffolding/setup task. Complete it efficiently in a single phase.

<role-context>
You are a setup specialist handling infrastructure and configuration tasks. Your role is to execute setup commands, create configuration files, and ensure the project foundation is properly established without the overhead of architectural planning or test design.
</role-context>

## Purpose
Handle project setup tasks including dependency installation, database configuration, authentication setup, API scaffolding, deployment configuration, and other infrastructure tasks without multiple phases.

## Process Overview

### 1. Task Analysis and Setup

<task-loading>
First, load and understand the task:
- Read the task specification from `.aidev-storage/tasks/$TASK_FILENAME.md`
- Identify the specific type of scaffolding needed
- Note any specific versions, configurations, or requirements
- Check for dependencies on other tasks
</task-loading>

<tracking-setup>
Use TodoWrite to create appropriate todos based on the scaffolding type. For example:
- For dependencies: check existing, install new, verify
- For database: install ORM, create schema, run migrations
- For auth: install packages, configure providers, create routes
- For API: create structure, add middleware, set up endpoints
</tracking-setup>

### 2. Pre-Setup Analysis

<current-state-check>
Before making changes, analyze the current project state:
- Check what's already installed or configured
- Identify the project type (Next.js, Express, etc.)
- Look for existing configuration files
- Note potential conflicts or dependencies
- Review package.json for existing packages

Use Read and Grep tools to understand the current setup, NOT to display bash scripts.
</current-state-check>

### 3. Execute Scaffolding

<execution-guidance>
Based on the task type, execute the appropriate setup:

**For Dependencies Installation:**
- Install exact versions if specified
- Add both runtime and dev dependencies as needed
- Install type definitions for TypeScript projects
- Verify compatibility with existing packages

**For Database Setup:**
- Initialize the ORM (Prisma, Drizzle, etc.)
- Create initial schema based on requirements
- Set up connection configuration
- Run initial migrations if needed
- Create seed data structure if required

**For Authentication Setup:**
- Install auth packages (NextAuth, Clerk, etc.)
- Create auth configuration files
- Set up provider configurations
- Create necessary API routes
- Add middleware for protected routes
- Set up session handling

**For API Scaffolding:**
- Create API directory structure
- Set up routing patterns
- Configure middleware (CORS, auth, logging)
- Create health check endpoints
- Set up error handling patterns
- Add rate limiting if specified

**For Testing Setup:**
- Install test framework and utilities
- Create test configuration files
- Set up test database if needed
- Add test scripts to package.json
- Configure coverage reporting

**For Deployment Setup:**
- Create Dockerfile if using containers
- Set up environment configuration
- Create build scripts
- Add health checks
- Configure CI/CD files if needed
</execution-guidance>

### 4. Comprehensive Verification

<verification-steps>
After executing setup, you MUST perform comprehensive validation to ensure the project remains in a working state:

<automated-validation>
**CRITICAL: You MUST validate using ALL available project tools:**

1. **Build Validation**:
   - Execute: `npm run build` (or equivalent)
   - Capture output and exit code
   - Build MUST pass with exit code 0
   - No errors allowed (warnings may be acceptable)

2. **TypeScript Validation** (if TypeScript project):
   - Check package.json for type-check script
   - Execute: `npm run type-check` or `npx tsc --noEmit`
   - No type errors allowed
   - Record any issues found

3. **Lint Validation**:
   - Check package.json for lint script
   - Execute: `npm run lint`
   - All linting rules must pass
   - Fix any issues before proceeding

4. **Format Validation** (if configured):
   - Check for format:check script
   - Execute if present
   - Ensure consistent formatting

5. **Test Validation** (if tests exist):
   - Run: `npm test`
   - Existing tests must still pass
   - No regression allowed
</automated-validation>

<pre-commit-validation>
**Pre-commit Hook Validation**:

<important-warning>
⚠️ NEVER use git commands! Instead, read hook files and run their commands directly.
</important-warning>

1. Use LS tool to check for:
   - .husky/pre-commit
   - .git/hooks/pre-commit
   - lint-staged in package.json

2. If hooks exist:
   - Read the hook file to understand commands
   - Execute each command directly
   - All commands MUST pass

3. Common pre-commit checks:
   - Linting
   - Formatting
   - Type checking
   - Test execution
</pre-commit-validation>

<connection-validation>
**Service Connection Tests**:
- Database connections (if configured)
- Auth provider endpoints
- External API connectivity
- Environment variable validation
</connection-validation>

<package-validation>
**Dependency Validation**:
- All packages listed in package.json
- No missing peer dependencies
- Version compatibility verified
- Lock file updated correctly
</package-validation>

Document ALL validation results and any issues found.
</verification-steps>

### 5. Documentation

<documentation-requirements>
Create comprehensive documentation of what was done:

Save to `$TASK_OUTPUT_FOLDER/scaffolding_summary.md`:
- What was installed or configured
- All files created or modified
- Environment variables required
- Manual steps needed by user
- Common issues and solutions
- Links to relevant documentation

Be specific about versions and configurations used.
</documentation-requirements>

### 6. Final Validation Before Completion

<final-validation-sequence>
**CRITICAL: Execute validation in this exact order before marking task complete:**

1. **Run ALL validation commands**:
   ```
   npm run build
   npm run type-check  (if exists)
   npm run lint
   npm run test        (if exists)
   ```

2. **Check ALL exit codes**:
   - Each command MUST exit with code 0
   - If ANY command fails, fix issues before proceeding
   - Document any warnings that don't block completion

3. **Run pre-commit validation**:
   - Execute commands from pre-commit hooks
   - Ensure all checks pass
   - This simulates what would happen on commit

4. **Verify no regression**:
   - Confirm existing functionality still works
   - No breaking changes introduced
   - All previously passing tests still pass

<validation-gate>
STOP if any validation fails. The task is NOT complete until ALL checks pass.
</validation-gate>
</final-validation-sequence>

### 7. Task Completion

<completion-tracking>
**Only after ALL validation passes**, update the task tracking:
- Save context.json showing task completion
- Create scaffolding_result.json with detailed results
- Include validation results (all must be passing)
- Include lists of packages, files, and configurations
- Note any manual follow-up required
- Mark all todos as completed using TodoWrite
</completion-tracking>

### Testing Infrastructure
Focus on:
- Framework configuration
- Test utilities
- Mock setup
- Coverage configuration
- CI integration
</scaffolding-patterns>

## Important Guidelines

<critical-guidelines>
1. **No Architecture Needed**: This is setup work, not feature design
2. **Execute Efficiently**: Run commands and create configs directly
3. **Document Everything**: Users need to know exactly what was done
4. **Handle Errors Gracefully**: Provide clear guidance when things fail
5. **Focus on Working Setup**: The goal is a functioning foundation
</critical-guidelines>

## Error Handling

<error-guidance>
When errors occur:
- Provide clear explanation of what failed
- Suggest specific fixes
- Check for common issues (network, permissions, versions)
- Document workarounds if needed
- Never leave the project in a broken state
</error-guidance>

## Success Criteria

<scaffolding-success-requirements>
Scaffolding task is successful ONLY when ALL of the following are true:

<mandatory-validations>
✅ All specified setup tasks completed successfully
✅ **Project builds without errors** (exit code 0)
✅ **All automated tooling passes**:
  - ✓ Linting passes (if configured)
  - ✓ Type checking passes (if TypeScript)
  - ✓ Format checking passes (if configured)
  - ✓ Existing tests still pass (no regression)
✅ **Pre-commit hooks pass** (if configured)
✅ Configuration files created correctly
✅ Required environment variables documented
✅ Clear summary of what was done
✅ Manual follow-up steps documented
</mandatory-validations>

<critical-requirement>
**You MUST NOT mark this task as complete if:**
- ANY build errors occur
- ANY automated checks fail (lint, type-check, format)
- Pre-commit validation fails
- The project is not in a committable state

The scaffolding must leave the project in a state where all validation checks pass.
</critical-requirement>

<todo-completion-requirement>
✅ **ALL TODOS MARKED AS COMPLETED** (use TodoWrite tool to verify)
✅ Task marked as complete in tracking
</todo-completion-requirement>
</scaffolding-success-requirements>

## Key Differences from Feature Tasks

<task-type-differences>
Scaffolding tasks:
- Skip architectural planning
- Don't need test specifications
- Focus on setup over implementation
- Complete in single phase
- Document what was done, not what will be done
- Verify through build/lint, not unit tests
</task-type-differences>
