Part 2: Shell Scripting (bash/zsh)

General Principles

Generate clean, simple, and concise code
Ensure scripts are easily readable and understandable
Add comments where needed for understanding
Generate concise echo outputs for execution status
Avoid unnecessary output and excessive logging

Error Handling & Safety

Enable Strict Mode

Always enable strict mode at the top of scripts:

#!/bin/bash
set -euo pipefail

-e: Exit on first error
-u: Treat unset variables as errors
-o pipefail: Surface pipeline failures

Cleanup with Traps

cleanup() {
    # Remove temporary files
    if [[ -n "${TEMP_DIR:-}" && -d "$TEMP_DIR" ]]; then
        rm -rf "$TEMP_DIR"
    fi

    # Close connections
    if [[ -n "${CONNECTION:-}" ]]; then
        echo "Closing connection..."
        # connection close logic
    fi
}

trap cleanup EXIT



## Skill Paths

- Workspace skills: `.github/skills/`
- Global skills: `C:/Users/LOQ/.agents/skills/`

trap 'echo "Interrupted"; cleanup; exit 1' INT TERM

Validate Requirements

validate_requirements() {
    local errors=0

    # Check required variables
    if [[ -z "${RESOURCE_GROUP:-}" ]]; then
        echo "Error: RESOURCE_GROUP environment variable not set" >&2
        ((errors++))
    fi

    # Check required commands
    for cmd in curl jq az; do
        if ! command -v "$cmd" &> /dev/null; then
            echo "Error: $cmd is not installed" >&2
            ((errors++))
        fi
    done

    # Return appropriate exit code
    return $errors
}

Part 3: PowerShell Scripting

General Practices

Use proper cmdlet names instead of aliases (e.g., Get-ChildItem, not dir)
Quote paths with spaces: "C:\Path With Spaces\file.txt"
Use ShouldProcess for destructive operations
Implement proper error handling with try-catch
Parameterize scripts for reusability

DevOps Best Practices

Git

Use conventional commits
Keep commits small and focused
Write clear, descriptive messages
Keep feature branches short-lived
Rebase feature branches before merging
Sign commits for security-critical projects

Shell Scripting

Always use strict mode (set -euo pipefail)
Quote variables properly
Handle errors gracefully with traps
Validate inputs and parameters
Use functions for reusability
Add proper error messages to stderr

PowerShell

Use strict mode for security
Use proper cmdlet names (no aliases)
Implement error handling with try-catch
Test scripts thoroughly
Use parameter validation
Handle pipeline errors properly

CI/CD

Use secure variable management for secrets
Cache dependencies to speed up builds
Run tests on multiple environments
Use matrix builds for different configurations
Implement proper artifact management
Add deployment gates and approvals
Provide clear build status
