DevOps Documentation Creator

Type: L3 Worker

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}

MANDATORY READ: Load shared/references/docs_quality_contract.md, shared/references/docs_quality_rules.json, and shared/references/markdown_read_protocol.md.

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 - Preserve the shared opening contract and standard top sections from the template - 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 - Never leave template markers in published infrastructure docs - If data is missing: omit the claim or use a concise neutral fallback, but do NOT emit [TBD:...]

1. Conditional Section Pruning:

- If no CI/CD detected: replace with concise empty-state note, not [TBD:...] - If no ARTIFACT_REPOSITORY: replace with concise empty-state note, not [TBD:...] - 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 - Preserve the shared opening contract and standard top sections from the template - Populate setup steps from package.json scripts - Extract env vars from.env.example - Never leave template markers in published runbooks - If data is missing: omit the claim or use a concise neutral fallback, but do NOT emit [TBD:...]

1. 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: replace with concise empty-state note, not [TBD:...] - 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 and metadata markers
2. Check required top sections (Quick Navigation, Agent Entry, Maintenance)
3. Validate sections: Server Inventory, Port Allocation, Deployed Services
4. Check no procedural content leaked (belongs in runbook.md)
5. Check docs-quality contract compliance (no forbidden placeholders, no leaked template metadata, valid doc kind/role)

For runbook.md (if created):

1. Check SCOPE tag and metadata markers
2. Check required top sections (Quick Navigation, Agent Entry, Maintenance)
3. Validate sections: Local Development Setup, Deployment, Troubleshooting
4. Check env vars documented
5. Check docs-quality contract compliance (no forbidden placeholders, no leaked template metadata, valid doc kind/role)

Phase 4: Return Status

{
  "created_files": ["docs/project/infrastructure.md", "docs/project/runbook.md"],
  "skipped_files": [],
  "quality_inputs": {
    "doc_paths": ["docs/project/infrastructure.md", "docs/project/runbook.md"],
    "owners": {
      "docs/project/infrastructure.md": "ln-115-devops-docs-creator",
      "docs/project/runbook.md": "ln-115-devops-docs-creator"
    }
  },
  "validation_status": "passed"
}

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
• Publishable output: No [TBD:...], TODO, or leaked template metadata in DevOps docs

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

Runtime Summary Artifact

MANDATORY READ: Load shared/references/docs_generation_summary_contract.md

Accept optional summaryArtifactPath.

Summary kind:

• docs-generation

Required payload semantics:

• worker = "ln-115"
• status
• created_files
• skipped_files
• quality_inputs
• validation_status
• warnings

Write the summary to the provided artifact path or return the same envelope in structured output.

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

Reference Files

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