Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/levnikolaevich/claude-code-skills --skill ln-730-devops-setup
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads ln-730-devops-setup automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Paths: File paths (references/, ../ln-*) are relative to this skill directory.

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

AspectDetails
InputProject directory with source code
OutputDocker, CI/CD, environment configuration
Workersln-731 (Docker), ln-732 (CI/CD), ln-733 (Environment)
ModeAuto-detect (no user prompts)

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:

DetectionMethodFiles to Check
FrontendPackage.json presencesrc/frontend/package.json, package.json
Backend .NET.csproj/.sln presence*.sln, src/**/*.csproj
Backend Pythonrequirements.txt/pyproject.tomlrequirements.txt, pyproject.toml
DatabaseConnection strings in codeappsettings.json, .env.example
Existing CI/CDWorkflow 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)

Host Skill Invocation: Skill(skill: "...", args: "...") is mandatory delegation.

  • Claude: call the Skill tool exactly as shown.
  • Codex: if no Skill tool exists, locate the named skill in available skills, read its SKILL.md, treat args as $ARGUMENTS, execute that skill workflow, then return here with its result/artifact.
  • Do not inline worker logic or mark the worker complete without executing the target skill.
PhaseWorkerContext
3aln-731-docker-generatorShared (Skill tool) — Dockerfiles, docker-compose, .dockerignore
3bln-732-cicd-generatorShared (Skill tool) — CI/CD pipeline configuration
3cln-733-env-configuratorShared (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)
  • 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

Optional reference: load references/meta_analysis_protocol.md only when the user asks for post-run meta-analysis or protocol-formatted run reflection.

Skill type: execution-orchestrator. When requested, run after all phases complete. Output to chat using the execution-orchestrator format.
