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}.

Project Core Documentation Creator

L3 Worker that creates 4 core project documentation files. These are ALWAYS created regardless of project type.

Purpose & Scope

• Creates 4 core project documentation files (required for all projects)
• Receives Context Store from ln-110-project-docs-coordinator
• Heavy use of auto-discovery (architecture needs full project scan)
• Replaces placeholders with project-specific data
• Self-validates structure and content (16+ questions)
• Never gathers context itself; uses coordinator input

Invocation (who/when)

• ln-110-project-docs-coordinator: ALWAYS invoked as second worker (after ln-111)
• Never called directly by users

Inputs

From coordinator:

• contextStore: Full Context Store with all discovered data
  • PROJECT_NAME, PROJECT_DESCRIPTION
  • TECH_STACK (full object: frontend, backend, database, etc.)
  • DEPENDENCIES (from package.json)
  • SRC_STRUCTURE (folder analysis)
  • EXTERNAL_SYSTEMS (from .env.example)
  • CODE_CONVENTIONS (from eslint, prettier)
  • ADR_LIST (from docs/reference/adrs/)
  • LEGACY_CONTENT (optional, from ln-100 Phase 0 migration):
    • legacy_architecture: { layers[], components[], diagrams[], data_flow }
    • legacy_requirements: { functional[], non_functional[], user_stories[] }
    • legacy_tech_stack: { frontend, backend, database, versions }
• targetDir: Project root directory

LEGACY_CONTENT is used as base content when creating documents. Priority: Legacy > Auto-discovery > Template defaults.

Documents Created (4)

Workflow

Phase 1: Receive Context

1. Parse full Context Store from coordinator
2. Validate required keys (PROJECT_NAME, TECH_STACK)
3. Extract architecture-specific data (SRC_STRUCTURE, DEPENDENCIES)

Phase 2: Create Documents

For each document (requirements.md, architecture.md, tech_stack.md, patterns_catalog.md):

1. Check if file exists (idempotent)
2. If exists: skip with log
3. If not exists:
   • Copy template from references/templates/
   • Check LEGACY_CONTENT for this document type:
     • For architecture.md: If LEGACY_CONTENT.legacy_architecture exists:
       • Use legacy_architecture.layers[] for "## Building Block View" (Section 5)
       • Use legacy_architecture.components[] for component descriptions
       • Use legacy_architecture.diagrams[] for existing diagrams (preserve mermaid/images)
       • Use legacy_architecture.data_flow for "## Runtime View" (Section 6)

Phase 3: Self-Validate

For each created document:

1. Check SCOPE tag in first 10 lines
2. Check required sections (from questions_core.md)
3. Validate specific format requirements:
   • requirements.md: FR-XXX identifiers, MoSCoW labels
   • architecture.md: 11 sections, C4 diagrams, ADR references
   • tech_stack.md: versions, rationale for each technology
4. Check Maintenance section
5. Auto-fix issues where possible

Phase 4: Return Status

Return to coordinator:

{
  "created": ["docs/project/requirements.md", ...],
  "skipped": [],
  "tbd_count": 5,
  "validation": "OK",
  "diagrams_generated": 3
}

Critical Notes

• Idempotent: Never overwrite existing files
• Heavy auto-discovery: architecture.md requires deep project analysis
• C4 diagrams: Generated from SRC_STRUCTURE in Mermaid format
• ADR integration: Section 8 links to docs/reference/adrs/
• arc42 compliance: ISO/IEC/IEEE 42010:2022 structure
• TBD markers: Use [TBD: X] for missing data

NO_CODE_EXAMPLES Rule (MANDATORY)

Documents describe contracts and decisions , NOT implementations:

• FORBIDDEN: Code blocks > 5 lines, function implementations, imports, DI configuration
• ALLOWED: Mermaid diagrams, component tables, method signatures (1 line), ADR links
• INSTEAD OF CODE: Reference source: "See src/Services/UserService.cs:45"
• TEMPLATE RULE: All templates include <!-- NO_CODE_EXAMPLES: ... --> tag - FOLLOW IT

Stack Adaptation Rule (MANDATORY)

• Links must reference stack-appropriate docs (Microsoft for .NET, MDN for JS)
• Never mix stack references (no Python examples in .NET project)

Format Priority (MANDATORY)

Tables > Mermaid/ASCII diagrams > Lists > Text

Definition of Done

• Context Store received and validated
• 4 core documents created (or skipped if exist)
• C4 diagrams generated (Context, Container, Component)
• ADR links populated
• Patterns auto-detected and added to catalog
• Self-validation passed (SCOPE, sections, format)
• 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/requirements_template.md, architecture_template.md, tech_stack_template.md
• Patterns template: shared/templates/patterns_template.md
• Questions: references/questions_core.md (Q23-Q38)
