Reference Documentation Creator

This skill creates the reference documentation structure (docs/reference/) and smart documents (ADRs, Guides, Manuals) based on project's TECH_STACK. Documents are created only when justified (nontrivial technology choices with alternatives).

When to Use This Skill

This skill is a L2 WORKER invoked by ln-100-documents-pipeline orchestrator.

This skill should be used directly when:

• Creating only reference documentation structure (docs/reference/)
• Setting up directories for ADRs, guides, and manuals
• NOT creating full documentation structure (use ln-100-documents-pipeline for complete setup)

Inputs

From ln-100 (via ln-110 Context Store):

{
  "context_store": {
    "PROJECT_NAME": "my-project",
    "TECH_STACK": {
      "frontend": "React 18",
      "backend": "Express 4.18",
      "database": "PostgreSQL 15",
      "orm": "Prisma 5.0",
      "auth": "JWT",
      "cache": "Redis 7"
    },
    "DEPENDENCIES": [...],
    "flags": { "hasBackend": true, "hasDatabase": true, "hasFrontend": true }
  }
}

TECH_STACK is used for smart document creation in Phase 2.

How It Works

The skill follows a 4-phase workflow: CREATE STRUCTURE → SMART DOCUMENT CREATION → VALIDATE STRUCTURE → VALIDATE CONTENT. Phase 2 creates documents only for justified technology choices.

Phase 1: Create Structure

Objective: Establish reference documentation directories and README hub.

Process:

1.1 Check & create directories:

• Check if docs/reference/adrs/ exists → create if missing
• Check if docs/reference/guides/ exists → create if missing
• Check if docs/reference/manuals/ exists → create if missing
• Check if docs/reference/research/ exists → create if missing
• Log for each: "✓ Created docs/reference/[name]/" or "✓ docs/reference/[name]/ already exists"

1.2 Check & create README:

• Check if docs/reference/README.md exists
• If exists:
  • Skip creation
  • Log: "✓ docs/reference/README.md already exists, proceeding to validation"
• If NOT exists:
  • Copy template: ln-112-reference-docs-creator/references/reference_readme_template.md → docs/reference/README.md
  • Replace placeholders:
    • {{VERSION}} — "1.0.0"
    • {{DATE}} — current date (YYYY-MM-DD)
    • {{ADR_LIST}} — kept as placeholder (filled in Phase 4)
    • {{GUIDE_LIST}} — kept as placeholder (filled in Phase 4)
    • {{MANUAL_LIST}} — kept as placeholder (filled in Phase 4)
  • Log: "✓ Created docs/reference/README.md from template"

1.3 Output:

docs/reference/
├── README.md         # Created or existing
├── adrs/            # Empty, ready for ADRs
├── guides/          # Empty, ready for guides
├── manuals/         # Empty, ready for manuals
└── research/        # Empty, ready for research documents

Phase 2: Smart Document Creation

Objective: Create ADRs, Guides, and Manuals for justified technology choices. Skip trivial/obvious selections.

2.1 Check Context Store:

• If no context_store provided → skip Phase 2, proceed to Phase 3
• If no TECH_STACK in context_store → skip Phase 2, proceed to Phase 3
• Log: "Context Store received with TECH_STACK: [categories count]"

2.2 Load Justification Rules:

• Read references/tech_justification_rules.md
• Parse category → justified/skip conditions

2.3 Analyze TECH_STACK for ADRs:

For each category in TECH_STACK (frontend, backend, database, orm, auth, cache):

1. Check if justified (from justification rules):

   • frontend: Justified if React/Vue/Angular/Svelte (multiple options exist)
   • backend: Justified if Express/Fastify/NestJS/Koa (multiple options exist)
   • database: Justified if PostgreSQL/MySQL/MongoDB (multiple options exist)
   • auth: Justified if JWT/OAuth/Session (decision required)
   • orm: Justified if Prisma/TypeORM/Sequelize (multiple options exist)
   • cache: Justified if Redis/Memcached (decision required)

2. Skip if trivial:

   • jQuery-only frontend (no framework choice)
   • Simple http server (no framework)
   • SQLite for dev only
   • No auth required
   • Raw SQL only
   • In-memory cache only

3. Create ADR if justified:

   • Determine next ADR number: adr-NNN-{category}.md
   • Use template: shared/templates/adr_template.md
   • MCP Research: mcp__context7__resolve-library-id(technology)
   • Fill template:
     • Title: "ADR-NNN: {Category} Selection"
     • Context: Why decision was needed
     • Decision: Technology chosen with version
     • Rationale: 3 key reasons from research
     • Alternatives: 2 other options with pros/cons
   • Save: docs/reference/adrs/adr-NNN-{category}.md
   • Log: "✓ Created ADR for {category}: {technology}"

4. Skip if not justified:

   • Log: "⊘ Skipped ADR for {category}: trivial choice"

2.4 Analyze TECH_STACK for Guides:

For each technology with complex configuration:

1. Check if justified:
   • Has config file with
