Agent Skills: Root Documentation Creator

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}.

Root Documentation Creator

Type: L3 Worker

L3 Worker that creates 6 root documentation files using templates and Context Store from coordinator.

Purpose & Scope

• Creates 6 root documentation files (entry points for AI agents)
• Receives Context Store from ln-110-project-docs-coordinator
• Replaces placeholders with project-specific data
• Self-validates structure and content (22 questions)
• Never gathers context itself; uses coordinator input

Inputs

From coordinator:

• contextStore: Key-value pairs with all placeholders
  • PROJECT_NAME, PROJECT_DESCRIPTION
  • TECH_STACK_SUMMARY
  • DEV_COMMANDS (from package.json scripts)
  • DATE (current date)
  • ENABLE_WORKFLOW_PRINCIPLES (optional boolean; default false) — when true, expands the {{WORKFLOW_PRINCIPLES_BLOCK}} placeholder in AGENTS.md with the content of references/templates/agents_md_workflow_principles.md
• targetDir: Project root directory

MANDATORY READ: Load shared/references/docs_quality_contract.md, shared/references/docs_quality_rules.json, and shared/references/agent_instructions_writing_guide.md (the canonical writing guide for AGENTS.md / CLAUDE.md / GEMINI.md).

Documents Created (6)

| File | Target Sections | Questions | |------|-----------------|-----------| | AGENTS.md | Quick Navigation, Agent Entry, Critical Rules, (optional) Workflow Principles, Development Commands, Maintenance | Q1-Q6 | | CLAUDE.md | @AGENTS.md import + ## Claude Code delta (≤20 lines total) | Q1-Q6 | | GEMINI.md | @AGENTS.md import + ## Gemini CLI delta (≤20 lines total) | Q1-Q6 | | docs/README.md | Quick Navigation, Agent Entry, Documentation Map, Maintenance | Q7-Q13 | | docs/documentation_standards.md | Quick Reference (60+ requirements), 12 main sections, Maintenance | Q14-Q16 | | docs/principles.md | Core Principles (8), Decision Framework, Anti-Patterns, Verification, Maintenance | Q17-Q22 |

Workflow

Phase 1: Receive Context

1. Parse Context Store from coordinator
2. Validate required keys present (PROJECT_NAME, PROJECT_DESCRIPTION)
3. Set defaults for missing optional keys (ENABLE_WORKFLOW_PRINCIPLES defaults to false)

Phase 2: Create Documents

For each document (AGENTS.md, CLAUDE.md, GEMINI.md, docs/README.md, docs/documentation_standards.md, docs/principles.md):

1. Check if file exists (idempotent)
2. If exists: skip with log
3. If not exists:
   • Copy template from references/templates/
   • For AGENTS.md: enforce the shared header contract (SCOPE, DOC_KIND, DOC_ROLE: canonical, READ_WHEN, SKIP_WHEN, PRIMARY_SOURCES) and the top-section contract (## Quick Navigation, ## Agent Entry, ## Critical Rules, ## Maintenance)
   • For AGENTS.md: if ENABLE_WORKFLOW_PRINCIPLES=true, replace the {{WORKFLOW_PRINCIPLES_BLOCK}} placeholder with the full content of references/templates/agents_md_workflow_principles.md; otherwise strip the placeholder line and its leading comment
   • For CLAUDE.md and GEMINI.md: use the import-stub templates (claude_md_template.md, gemini_md_template.md). They contain DOC_ROLE: derived, a single @AGENTS.md line, and a bounded harness-specific delta. Do not inline any AGENTS.md content
   • For docs/principles.md: prefer normalized principle inputs already present in Context Store
   • If project-specific principles are absent, keep the template structure and fill only facts supported by current project sources
   • Replace {{PLACEHOLDER}} tokens with Context Store values
   • Never leave template markers in published root docs
   • If data is missing: omit the claim or use a concise neutral fallback, but do NOT emit [TBD: ...]
   • Write file

Root entrypoint rule (canonical model):

• AGENTS.md is the single canonical source of content. It holds the Critical Rules table, MCP Tool Preferences, Navigation, Development Commands, and optional Workflow Principles.
• CLAUDE.md is a Claude Code-specific stub that contains @AGENTS.md plus a ## Claude Code delta with harness-specific rules (≤20 lines total, ≤50 absolute max). Do not duplicate AGENTS.md content.
• GEMINI.md is the Gemini CLI analog with @AGENTS.md plus a ## Gemini CLI delta.
• Both Claude Code and Gemini CLI natively expand @path imports into the session context at launch (5-hop recursion), so the imported AGENTS.md is available to both harnesses automatically.
• Harness delta content: command terminology (/compact, /memory show), storage pointers (~/.claude/projects/<project>/memory/), and features that only exist in one harness (.claude/rules/ with paths: frontmatter, nested on-demand loading).

Phase 3: Self-Validate

For each created document:

1. Check SCOPE tag in first 12 lines
2. Check metadata markers (DOC_KIND, DOC_ROLE, READ_WHEN, SKIP_WHEN, PRIMARY_SOURCES)
3. For AGENTS.md: check Quick Navigation, Agent Entry, Critical Rules, Maintenance
4. For CLAUDE.md / GEMINI.md: check @AGENTS.md import line is present and the file is ≤50 lines
5. Check required sections (from questions_root.md)
6. Check docs-quality contract compliance (no forbidden placeholders, no leaked template metadata)
7. Check POSIX endings (single newline at end)
8. Auto-fix issues where possible

Phase 4: Return Status

Return to coordinator:

{
  "created_files": ["AGENTS.md", "CLAUDE.md", "GEMINI.md", "docs/README.md", "docs/documentation_standards.md", "docs/principles.md"],
  "skipped_files": [],
  "quality_inputs": {
    "doc_paths": ["AGENTS.md", "CLAUDE.md", "GEMINI.md", "docs/README.md", "docs/documentation_standards.md", "docs/principles.md"],
    "owners": {
      "AGENTS.md": "ln-111-root-docs-creator",
      "CLAUDE.md": "ln-111-root-docs-creator",
      "GEMINI.md": "ln-111-root-docs-creator",
      "docs/README.md": "ln-111-root-docs-creator",
      "docs/documentation_standards.md": "ln-111-root-docs-creator",
      "docs/principles.md": "ln-111-root-docs-creator"
    }
  },
  "validation_status": "passed"
}

Critical Notes

Core Rules

• Idempotent: Never overwrite existing files; skip and log
• No context gathering: All data comes from coordinator's Context Store
• Publishable output: Root docs must not contain [TBD: ...], TODO, or leaked template metadata
• Language: All root docs in English (universal standards)
• SCOPE tags: Required in first 10 lines of each file (HTML comments are stripped from Claude Code's injected context but stay visible to maintainers and auditors)
• Canonical-stub root model: AGENTS.md is the single source; CLAUDE.md and GEMINI.md are @AGENTS.md imports plus bounded harness deltas. See shared/references/agent_instructions_writing_guide.md for rationale and anti-patterns.

NO_CODE_EXAMPLES Rule (MANDATORY)

Root documents define navigation and standards, NOT implementations:

• FORBIDDEN: Code blocks, implementation snippets
• ALLOWED: Tables, links, command examples (1 line)
• TEMPLATE RULE: All templates include <!-- NO_CODE_EXAMPLES: ... --> tag - FOLLOW IT

Stack Adaptation Rule (MANDATORY)

• All external links must match project stack (detected in Context Store)
• .NET project → Microsoft docs; Node.js → MDN, npm docs; Python → Python docs
• Never mix stack references (no Python examples in .NET project)

Format Priority (MANDATORY)

Tables/ASCII > Lists (enumerations only) > Text (last resort)

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-111"
• 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

• [ ] Context Store received and validated
• [ ] 6 root documents created (or skipped if exist)
• [ ] All placeholders replaced; no [TBD: ...] markers or template metadata remain in root docs
• [ ] CLAUDE.md and GEMINI.md each contain exactly one @AGENTS.md line and a bounded harness delta (≤50 lines total)
• [ ] If ENABLE_WORKFLOW_PRINCIPLES=true: the workflow principles shard is expanded in AGENTS.md; if false: the placeholder line is stripped
• [ ] Self-validation passed (SCOPE, metadata markers, top sections, Maintenance, POSIX)
• [ ] Actuality verified: all document facts match current code (paths, functions, APIs, configs exist and are accurate)
• [ ] Status returned
