+# Change: Add Development Scripts
+
+## Why
+Developers currently need to manually start multiple services (MinIO, backend, frontend) and verify environment prerequisites before running the application. This is error-prone and time-consuming. Automated scripts will streamline the development workflow and reduce onboarding friction.
+
+## What Changes
+- **NEW**: Environment check script (`check-env.sh`) - Validates all prerequisites
+- **NEW**: Unified development startup script (`start-dev.sh`) - Starts all services
+- **NEW**: Stop script (`stop-dev.sh`) - Gracefully stops all services
+
+## Impact
+- Affected specs: Creates new `dev-scripts` specification
+- Affected code:
+  - Shell scripts in project root directory
+  - No changes to existing application code
+
+## Dependencies
+- Existing docker-compose.minio.yml for MinIO
+- Python virtual environment (venv/)
+- Node.js and npm for frontend
+
+## Success Criteria
+1. `check-env.sh` validates Python 3.10+, Node.js, Docker, required ports
+2. `check-env.sh` provides clear error messages for missing prerequisites
+3. `start-dev.sh` starts MinIO, backend, and frontend in correct order
+4. `start-dev.sh` waits for each service to be healthy before proceeding
+5. `stop-dev.sh` gracefully terminates all services
+6. Scripts work on Linux/WSL environments

+# dev-scripts Specification
+
+## Purpose
+Shell scripts to automate development environment setup, validation, and service orchestration for the Task Reporter system.
+
+## ADDED Requirements
+
+### Requirement: Environment Validation
+The check-env script SHALL validate all prerequisites required to run the development environment.
+
+#### Scenario: Check Python version
+- **WHEN** the check-env script runs
+- **THEN** the system SHALL:
+  - Verify Python 3.10 or higher is installed
+  - Display the detected Python version
+  - Exit with error if Python version is insufficient
+
+#### Scenario: Check Node.js and npm
+- **WHEN** the check-env script runs
+- **THEN** the system SHALL:
+  - Verify Node.js is installed (v18+ recommended)
+  - Verify npm is available
+  - Display detected versions
+
+#### Scenario: Check Docker availability
+- **WHEN** the check-env script runs
+- **THEN** the system SHALL:
+  - Verify Docker daemon is running
+  - Verify docker-compose is available
+  - Display Docker version
+
+#### Scenario: Check virtual environment
+- **WHEN** the check-env script runs
+- **THEN** the system SHALL:
+  - Verify venv/ directory exists
+  - Suggest creation command if missing: `python -m venv venv`
+
+#### Scenario: Check environment file
+- **WHEN** the check-env script runs
+- **THEN** the system SHALL:
+  - Verify .env file exists
+  - Suggest copying from .env.example if missing
+  - Warn if critical variables appear empty (FERNET_KEY)
+
+#### Scenario: Check port availability
+- **WHEN** the check-env script runs
+- **THEN** the system SHALL:
+  - Check if ports 8000, 3000, 9000, 9001 are available
+  - Display which ports are in use and by what process
+  - Warn but continue if ports are occupied
+
+### Requirement: Development Server Startup
+The start-dev script SHALL orchestrate the startup of all development services in the correct order.
+
+#### Scenario: Pre-flight validation
+- **WHEN** the start-dev script runs
+- **THEN** the system SHALL:
+  - Execute check-env.sh first
+  - Abort startup if critical checks fail
+
+#### Scenario: Start MinIO
+- **WHEN** start-dev begins service startup
+- **THEN** the system SHALL:
+  - Start MinIO using docker-compose -f docker-compose.minio.yml up -d
+  - Wait for MinIO health check to pass (up to 30 seconds)
+  - Display MinIO console URL (http://localhost:9001)
+
+#### Scenario: Start backend server
+- **WHEN** MinIO is healthy
+- **THEN** the system SHALL:
+  - Activate the virtual environment
+  - Install/update requirements if requirements.txt is newer than last install
+  - Start uvicorn in background: uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
+  - Wait for backend to respond (up to 15 seconds)
+  - Display backend URL (http://localhost:8000)
+
+#### Scenario: Start frontend dev server
+- **WHEN** backend is healthy
+- **THEN** the system SHALL:
+  - Check if node_modules exists, run npm install if missing
+  - Start frontend dev server: npm run dev
+  - Display frontend URL (http://localhost:3000)
+
+#### Scenario: Display startup summary
+- **WHEN** all services are running
+- **THEN** the system SHALL:
+  - Display summary table with all service URLs
+  - Display log file locations
+  - Display instructions for stopping services
+
+#### Scenario: Handle graceful shutdown
+- **WHEN** user presses Ctrl+C during startup or operation
+- **THEN** the system SHALL:
+  - Trap the SIGINT signal
+  - Execute stop-dev.sh to clean up
+  - Display shutdown confirmation
+
+### Requirement: Development Server Shutdown
+The stop-dev script SHALL gracefully terminate all development services.
+
+#### Scenario: Stop frontend server
+- **WHEN** stop-dev script runs
+- **THEN** the system SHALL:
+  - Find and terminate the Vite dev server process
+  - Confirm termination or report if not running
+
+#### Scenario: Stop backend server
+- **WHEN** stop-dev script runs
+- **THEN** the system SHALL:
+  - Find and terminate the uvicorn process
+  - Confirm termination or report if not running
+
+#### Scenario: Stop MinIO
+- **WHEN** stop-dev script runs
+- **THEN** the system SHALL:
+  - Run docker-compose -f docker-compose.minio.yml down
+  - Preserve data volumes (do not use -v flag)
+  - Confirm MinIO container stopped
+
+#### Scenario: Display shutdown summary
+- **WHEN** all services are stopped
+- **THEN** the system SHALL:
+  - Display confirmation message for each service
+  - Report any services that failed to stop
