Ln 730 Devops Setup

Paths: File paths (shared/, references/, ../ln-*) are relative to skills repo root. If not found at CWD, locate this SKILL.md directory and go up one level for repo root. If shared/ is missing, fetch files via WebFetch from https://raw.githubusercontent.com/levnikolaevich/claude-code-skills/master/skills/{path}.

ln-730-devops-setup

Type: L2 Domain Coordinator Category: 7XX Project Bootstrap Parent: ln-700-project-bootstrap

Coordinates DevOps infrastructure setup by delegating to specialized workers.

Purpose & Scope

Orchestrates the complete DevOps setup for a project:

• Does: Auto-detect stack, delegate to workers, verify configuration
• Does NOT: Generate files directly (delegates to ln-731, ln-732, ln-733)

Overview

Supported Stacks

Workflow

Phase 1: Pre-flight Validation

Check required tools and project structure:

• Verify Docker is installed (docker --version)
• Verify docker-compose is available
• Check for existing DevOps files (warn if overwriting)

Output: Validation report or STOP with instructions

Phase 2: Project Analysis (Auto-detect)

Detect project stack automatically:

Version Detection:

• Node.js: Read from package.json engines or use node -v
• .NET: Read from *.csproj TargetFramework
• Python: Read from pyproject.toml or runtime.txt
• PostgreSQL: Default to latest stable (17)

Output: Stack configuration object with detected versions

Phase 3: Worker Delegation

Delegate to workers in parallel (independent tasks):

ln-730 (Coordinator)
    |
    +---> ln-731-docker-generator (via Skill tool)
    |         Input: stack config, versions
    |         Output: Dockerfile.*, docker-compose.yml, .dockerignore
    |
    +---> ln-732-cicd-generator (via Skill tool)
    |         Input: stack config, detected commands
    |         Output: .github/workflows/ci.yml
    |
    +---> ln-733-env-configurator (via Skill tool)
              Input: detected environment variables
              Output: .env.example, .env.development, .gitignore updates

Error Handling:

• If worker fails, log error and continue with others
• Report all failures at the end
• Suggest manual fixes for failed components

Invocations:

Skill(skill: "ln-731-docker-generator", args: "{projectPath}")
Skill(skill: "ln-732-cicd-generator", args: "{projectPath}")
Skill(skill: "ln-733-env-configurator", args: "{projectPath}")

Phase 4: Configuration Verification

Verify generated configuration:

• Run docker-compose config to validate syntax
• Check all referenced files exist
• Verify no secrets in committed files

Output: Verification report

Phase 5: Completion Report

Generate summary:

• List all created files
• Show detected stack configuration
• Provide next steps for user

Generated Files

Docker (ln-731)

• Dockerfile.frontend - Multi-stage build for frontend
• Dockerfile.backend - Multi-stage build for backend
• docker-compose.yml - Service orchestration
• docker-compose.override.yml - Development overrides (optional)
• .dockerignore - Build context exclusions

CI/CD (ln-732)

• .github/workflows/ci.yml - Main CI pipeline

Environment (ln-733)

• .env.example - Template with all variables
• .env.development - Development defaults
• .env.production - Production template (placeholders)
• .gitignore updates - Secrets protection

Critical Notes

1. Auto-detect Only: No interactive prompts. Uses detected values or sensible defaults.
2. Idempotent: Check file existence before creation. Warn before overwriting.
3. Parallel Execution: Workers are independent, can run in parallel.
4. Error Recovery: Continue on partial failures, report all issues at end.
5. Version Pinning: Use detected versions, not hardcoded values.

TodoWrite format (mandatory):

- Invoke ln-731-docker-generator (pending)
- Invoke ln-732-cicd-generator (pending)
- Invoke ln-733-env-configurator (pending)
- Verify configuration (pending)
- Generate completion report (pending)

Worker Invocation (MANDATORY)

All workers: Invoke via Skill tool — workers see coordinator context.

Definition of Done

• Pre-flight validation passed
• Stack auto-detected successfully
• All workers completed (or failures documented)
• docker-compose config validates successfully
• No secrets in generated files
• Completion report displayed

Reference Files

• Worker: ../ln-731-docker-generator/SKILL.md
• Worker: ../ln-732-cicd-generator/SKILL.md
• Worker: ../ln-733-env-configurator/SKILL.md

Meta-Analysis

MANDATORY READ: Load shared/references/meta_analysis_protocol.md

Skill type: execution-orchestrator. Run after all phases complete. Output to chat using the execution-orchestrator format.
