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}.

DevOps Documentation Creator

L3 Worker that creates infrastructure.md and runbook.md. Infrastructure inventory is always created; runbook is conditional on Docker presence.

Purpose & Scope

• Creates infrastructure.md (always) — declarative inventory: WHAT is deployed WHERE
• Creates runbook.md (if hasDocker) — procedural guide: HOW to deploy/restart/troubleshoot
• Receives Context Store from ln-110-project-docs-coordinator
• Never gathers context itself; uses coordinator input

Invocation (who/when)

• ln-110-project-docs-coordinator: ALWAYS invoked (infrastructure.md is unconditional)
• Never called directly by users

Inputs

From coordinator:

• contextStore: Context Store with DevOps-specific data
  • DOCKER_COMPOSE_DEV (development setup)
  • DOCKER_COMPOSE_PROD (production setup)
  • ENV_VARIABLES (from .env.example)
  • STARTUP_SEQUENCE (services order)
  • DEPLOYMENT_TARGET (AWS, Vercel, Heroku)
  • CI_CD_PIPELINE (from .github/workflows)
  • DOCKER_SERVICES (parsed from docker-compose.yml services)
  • DEPLOYMENT_SCALE ("single" | "multi" | "auto-scaling" | "gpu-based")
  • DEVOPS_CONTACTS (from CODEOWNERS, package.json author, git log)
  • HAS_GPU (detected from docker-compose nvidia runtime)
  • SERVER_INVENTORY (from SSH config, deploy targets)
  • DOMAIN_DNS (from docker-compose VIRTUAL_HOST vars, nginx configs)
  • ARTIFACT_REPOSITORY (from .env registry URLs, .npmrc, pip.conf)
  • HOST_REQUIREMENTS (from docker-compose deploy.resources.limits)
• targetDir: Project root directory
• flags: { hasDocker }

Documents Created (2: 1 always + 1 conditional)

Workflow

Phase 1: Check Conditions

1. Parse flags from coordinator
2. infrastructure.md: ALWAYS proceeds (no condition check)
3. runbook.md: Create ONLY if hasDocker=true
4. If target file already exists: skip that file (idempotent)

Phase 2a: Create infrastructure.md (unconditional)

1. Check if docs/project/infrastructure.md exists
2. If exists: skip with log
3. If not exists:
   • Copy references/templates/infrastructure_template.md
   • Replace placeholders with Context Store values
   • Populate Server Inventory from SERVER_INVENTORY
   • Populate Port Allocation from DOCKER_SERVICES port mappings
   • Populate Deployed Services from DOCKER_SERVICES
   • Populate CI/CD Pipeline from CI_CD_PIPELINE
   • Mark [TBD: X] for missing data
4. Conditional Section Pruning:
   • If no CI/CD detected: mark CI/CD Pipeline section as [TBD: Configure CI/CD]
   • If no ARTIFACT_REPOSITORY: mark Artifact Repository as [TBD: Configure registry]
   • If single server / no SERVER_INVENTORY: simplify to single-column table
   • If !HAS_GPU: remove GPU column from Server Inventory and Deployed Services
   • Populate Deployed Services ONLY from DOCKER_SERVICES (no generic examples)

Phase 2b: Create runbook.md (conditional)

1. If !hasDocker: skip entirely
2. Check if docs/project/runbook.md exists
3. If exists: skip with log
4. If not exists:
   • Copy references/templates/runbook_template.md
   • Replace placeholders with Context Store values
   • Populate setup steps from package.json scripts
   • Extract env vars from .env.example
   • Mark [TBD: X] for missing data
5. Conditional Section Pruning:
   • If DEPLOYMENT_SCALE != "multi" or "auto-scaling": Remove scaling/load balancer sections
   • If !HAS_GPU: Remove GPU-related sections (nvidia runtime, CUDA)
   • If service not in DOCKER_SERVICES: Remove that service's examples
   • If DEVOPS_CONTACTS empty: Mark as [TBD: Provide DevOps team contacts via Q50]
   • Populate service dependencies ONLY from DOCKER_SERVICES
   • Populate port mapping ONLY from docker-compose.yml ports section

Phase 3: Self-Validate

For infrastructure.md:

1. Check SCOPE tag
2. Validate sections: Server Inventory, Port Allocation, Deployed Services
3. Check no procedural content leaked (belongs in runbook.md)
4. Check Maintenance section

For runbook.md (if created):

1. Check SCOPE tag
2. Validate sections: Local Development Setup, Deployment, Troubleshooting
3. Check env vars documented
4. Check Maintenance section

Phase 4: Return Status

{
  "created": ["docs/project/infrastructure.md", "docs/project/runbook.md"],
  "skipped": [],
  "tbd_count": 3,
  "validation": "OK"
}

Critical Notes

Core Rules

• infrastructure.md: Always created, no condition
• runbook.md: Conditional on hasDocker
• Heavy auto-discovery: Most data from docker-compose.yml, .env.example, package.json, SSH config
• Reproducible: Setup steps must be testable and repeatable
• Idempotent: Never overwrite existing files

NO_CODE_EXAMPLES Rule (MANDATORY)

Both documents describe inventory/procedures , NOT implementations:

• FORBIDDEN: Full Docker configs, CI/CD pipelines (>5 lines), full nginx configs
• ALLOWED: Command examples (1-3 lines), env var tables, step lists, verification commands
• INSTEAD OF CODE: "See docker-compose.yml"

Stack Adaptation Rule (MANDATORY)

• Commands must match project stack (npm vs pip vs go)
• Link to correct cloud provider docs (AWS/Azure/GCP)
• Never mix stack references (no npm commands in Python project)

Format Priority (MANDATORY)

Tables (env vars, ports, services, servers) > Lists (setup steps) > Text

Definition of Done

• infrastructure.md created (always)
• runbook.md created if hasDocker
• Infrastructure: server inventory, ports, services documented
• Runbook: setup steps, deployment, troubleshooting documented
• All env vars from .env.example included in runbook
• Actuality verified: all document facts match current code (paths, functions, APIs, configs exist and are accurate)
• Status returned to coordinator

Reference Files

• Templates: references/templates/infrastructure_template.md, references/templates/runbook_template.md
• Questions: references/questions_devops.md (Q46-Q51 runbook, Q52-Q55 infrastructure)
