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

| Aspect | Details | |--------|---------| | Input | Project directory with source code | | Output | Docker, CI/CD, environment configuration | | Workers | ln-731 (Docker), ln-732 (CI/CD), ln-733 (Environment) | | Mode | Auto-detect (no user prompts) |

---

Supported Stacks

| Component | Option 1 | Option 2 | |-----------|----------|----------| | Frontend | React/Vite + Nginx | - | | Backend | .NET 8/9 | Python (FastAPI/Django) | | Database | PostgreSQL | - | | CI/CD | GitHub Actions | - |

---

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:

| Detection | Method | Files to Check | |-----------|--------|----------------| | Frontend | Package.json presence | src/frontend/package.json, package.json | | Backend .NET | .csproj/.sln presence | *.sln, src/**/*.csproj | | Backend Python | requirements.txt/pyproject.toml | requirements.txt, pyproject.toml | | Database | Connection strings in code | appsettings.json, .env.example | | Existing CI/CD | Workflow files | .github/workflows/, azure-pipelines.yml |

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)

| Phase | Worker | Context | |-------|--------|---------| | 3a | ln-731-docker-generator | Shared (Skill tool) — Dockerfiles, docker-compose, .dockerignore | | 3b | ln-732-cicd-generator | Shared (Skill tool) — CI/CD pipeline configuration | | 3c | ln-733-env-configurator | Shared (Skill tool) — environment files and .gitignore |

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)
