🚨 CRITICAL GUIDELINES Windows File Path Requirements

MANDATORY: Always Use Backslashes on Windows for File Paths

When using Edit or Write tools on Windows, you MUST use backslashes () in file paths, NOT forward slashes (/).

Examples:

❌ WRONG: D:/repos/project/file.tsx ✅ CORRECT: D:\repos\project\file.tsx

This applies to:

Edit tool file_path parameter Write tool file_path parameter All file operations on Windows systems Documentation Guidelines

NEVER create new documentation files unless explicitly requested by the user.

Priority: Update existing README.md files rather than creating new documentation Repository cleanliness: Keep repository root clean - only README.md unless user requests otherwise Style: Documentation should be concise, direct, and professional - avoid AI-generated tone User preference: Only create additional .md files when user specifically asks for documentation Modern Automation Patterns (2025) Overview

Production-ready patterns for DevOps automation, CI/CD pipelines, and cloud-native operations following 2025 industry standards.

Container-Aware Scripting Docker/Kubernetes Detection

!/usr/bin/env bash

set -euo pipefail

Detect container environment

detect_container() { if [[ -f /.dockerenv ]]; then echo "docker" elif grep -q docker /proc/1/cgroup 2>/dev/null; then echo "docker" elif [[ -n "${KUBERNETES_SERVICE_HOST:-}" ]]; then echo "kubernetes" else echo "host" fi }

Container-aware configuration

readonly CONTAINER_ENV=$(detect_container)

case "$CONTAINER_ENV" in docker|kubernetes) # Container-specific paths DATA_DIR="/data" CONFIG_DIR="/config" ;; host) # Host-specific paths DATA_DIR="/var/lib/app" CONFIG_DIR="/etc/app" ;; esac

Minimal Container Scripts

!/bin/sh

Use /bin/sh for Alpine-based containers (no bash)

set -eu # Note: No pipefail in POSIX sh

Check if running as PID 1

if [ $$ -eq 1 ]; then # PID 1 must handle signals properly trap 'kill -TERM $child 2>/dev/null' TERM INT

# Start main process in background
/app/main &
child=$!

# Wait for child
wait "$child"

else # Not PID 1, run directly exec /app/main fi

Health Check Scripts

!/usr/bin/env bash

healthcheck.sh - Container health probe

set -euo pipefail

Quick health check (< 1 second)

check_health() { local timeout=1

# Check process is running
if ! pgrep -f "myapp" > /dev/null; then
    echo "Process not running" >&2
    return 1
fi

# Check HTTP endpoint
if ! timeout "$timeout" curl -sf http://localhost:8080/health > /dev/null; then
    echo "Health endpoint failed" >&2
    return 1
fi

# Check critical files
if [[ ! -f /app/ready ]]; then
    echo "Not ready" >&2
    return 1
fi

return 0

}

check_health

CI/CD Pipeline Patterns GitHub Actions Helper

!/usr/bin/env bash

ci-helper.sh - GitHub Actions utilities

set -euo pipefail

Detect GitHub Actions

is_github_actions() { [[ "${GITHUB_ACTIONS:-false}" == "true" ]] }

GitHub Actions output

gh_output() { local name="$1" local value="$2"

if is_github_actions; then
    echo "${name}=${value}" >> "$GITHUB_OUTPUT"
fi

}

GitHub Actions annotations

gh_error() { if is_github_actions; then echo "::error::$" else echo "ERROR: $" >&2 fi }

gh_warning() { if is_github_actions; then echo "::warning::$" else echo "WARN: $" >&2 fi }

gh_notice() { if is_github_actions; then echo "::notice::$" else echo "INFO: $" fi }

Set job summary

gh_summary() { if is_github_actions; then echo "$*" >> "$GITHUB_STEP_SUMMARY" fi }

Usage example

gh_notice "Starting build" build_result=$(make build 2>&1) gh_output "build_result" "$build_result" gh_summary "## Build Complete\n\nStatus: Success"

Azure DevOps Helper

!/usr/bin/env bash

azdo-helper.sh - Azure DevOps utilities

set -euo pipefail

Detect Azure DevOps

is_azure_devops() { [[ -n "${TF_BUILD:-}" ]] }

if is_azure_devops; then
    echo "##vso[task.setvariable variable=$name]$value"
fi

}

Azure DevOps logging

azdo_error() { if is_azure_devops; then echo "##vso[task.logissue type=error]$" else echo "ERROR: $" >&2 fi }

Section grouping

azdo_section_start() { is_azure_devops && echo "##[section]$*" }

azdo_section_end() { is_azure_devops && echo "##[endsection]" }

Usage

azdo_section_start "Running Tests" test_result=$(npm test) azdo_output "test_result" "$test_result" azdo_section_end

Multi-Platform CI Detection

!/usr/bin/env bash

set -euo pipefail

Detect CI environment

detect_ci() { if [[ "${GITHUB_ACTIONS:-false}" == "true" ]]; then echo "github" elif [[ -n "${TF_BUILD:-}" ]]; then echo "azuredevops" elif [[ -n "${GITLAB_CI:-}" ]]; then echo "gitlab" elif [[ -n "${CIRCLECI:-}" ]]; then echo "circleci" elif [[ -n "${JENKINS_URL:-}" ]]; then echo "jenkins" else echo "local" fi }

Universal output

ci_output() { local name="$1" local value="$2" local ci_env ci_env=$(detect_ci)

case "$ci_env" in
    github)
        echo "${name}=${value}" >> "$GITHUB_OUTPUT"
        ;;
    azuredevops)
        echo "##vso[task.setvariable variable=$name]$value"
        ;;
    gitlab)
        echo "${name}=${value}" >> ci_output.env

        ;;
esac

}

Universal error

ci_error() { local ci_env ci_env=$(detect_ci)

case "$ci_env" in
    github)
        echo "::error::$*"
        ;;
    azuredevops)
        echo "##vso[task.logissue type=error]$*"
        ;;
    *)
        echo "ERROR: $*" >&2
        ;;
esac

}

if command -v parallel &> /dev/null; then # Process files in parallel export -f process_file find data/ -name "*.json" | parallel -j 4 process_file {} else # Fallback to bash background jobs max_jobs=4 job_count=0

for file in data/*.json; do
    process_file "$file" &

    ((job_count++))

# Start new job
"$@" &
JOB_POOL_PIDS+=($!)

}

job_pool_wait_any() { # Wait for any job to finish if ((${#JOB_POOL_PIDS[@]} > 0)); then local pid wait -n # Remove finished PIDs for i in "${!JOB_POOL_PIDS[@]}"; do if ! kill -0 "${JOB_POOL_PIDS[$i]}" 2>/dev/null; then unset 'JOB_POOL_PIDS[$i]' fi done JOB_POOL_PIDS=("${JOB_POOL_PIDS[@]}") # Reindex fi }

# Health check
echo "Running health checks..."
if ! check_health "$health_check_url"; then
    echo "Health check failed, rolling back" >&2
    return 1
fi

# Switch traffic to green
echo "Switching traffic to green..."
switch_traffic "green"

# Keep blue as backup for rollback
echo "Deployment complete. Blue environment kept for rollback."

}

check_health() { local url="$1" local max_attempts=30 local attempt=1

while ((attempt <= max_attempts)); do
    if curl -sf "$url" > /dev/null; then

echo "Starting canary deployment: $new_version"

for percentage in "${stages[@]}"; do
    echo "Rolling out to $percentage% of traffic..."

    # Update traffic split
    update_traffic_split "$percentage" "$new_version"

    # Monitor for issues
    echo "Monitoring for 5 minutes..."
    if ! monitor_metrics 300; then
        echo "Issues detected, rolling back" >&2
        update_traffic_split 0 "$new_version"
        return 1
    fi

    echo "Stage $percentage% successful"
done

echo "Canary deployment complete"

}

monitor_metrics() { local duration="$1" local end_time=$((SECONDS + duration))

while ((SECONDS < end_time)); do
    # Check error rate
    local error_rate
    error_rate=$(get_error_rate)

    if ((error_rate > 5)); then
        echo "Error rate too high: $error_rate%" >&2
        return 1
    fi

    sleep 10
done

return 0

}

Logging and Monitoring Structured Logging

!/usr/bin/env bash

set -euo pipefail

JSON structured logging

log_json() { local level="$1" local message="$2" shift 2

local timestamp
timestamp=$(date -u +"%Y-%m-%dT%H:%M:%SZ")

# Build JSON
local json
json=$(jq -n \
    --arg timestamp "$timestamp" \
    --arg level "$level" \
    --arg message "$message" \
    --arg script "$SCRIPT_NAME" \
    --argjson context "$(echo "$@" | jq -Rs .)" \
    '{
        timestamp: $timestamp,
        level: $level,
        message: $message,
        script: $script,
        context: $context
    }')

echo "$json" >&2

}

log_info() { log_json "INFO" "$@"; } log_error() { log_json "ERROR" "$@"; } log_warn() { log_json "WARN" "$@"; }

Usage

log_info "Processing file" "file=/data/input.txt" "size=1024"
