Meta-orchestrator: reads kanban board, lets user pick ONE Story, drives it through pipeline 300->310->400->500 via TeamCreate. Creates worktree isolation; coordinates workers + reports.

Project Documentation Coordinator

L2 Coordinator that gathers project context once and delegates document creation to specialized L3 workers.

Purpose & Scope

Single context gathering — analyzes project once, builds Context Store
Project type detection — determines hasBackend, hasDatabase, hasFrontend, hasDocker
Delegates to 5 workers — passes Context Store to each worker
Aggregates results — collects status from all workers, returns summary
Solves the "context loss" problem by gathering data once and passing explicitly

Invocation (who/when)

ln-100-documents-pipeline: Invoked as first L2 coordinator in documentation pipeline
Never called directly by users

Inputs

From ln-100 (via Phase 0 Legacy Migration):

{
  "LEGACY_CONTENT": {
    "legacy_architecture": { "sections": [...], "diagrams": [...] },
    "legacy_requirements": { "functional": [...] },
    "legacy_principles": { "principles": [...], "anti_patterns": [...] },
    "legacy_tech_stack": { "frontend": "...", "backend": "...", "versions": {} },
    "legacy_api": { "endpoints": [...], "authentication": "..." },
    "legacy_database": { "tables": [...], "relationships": [...] },
    "legacy_runbook": { "prerequisites": [...], "install_steps": [...], "env_vars": [...] },
    "legacy_infrastructure": { "servers": [...], "domains": [...], "ports": {} }
  }
}

LEGACY_CONTENT is passed to workers as base content. Priority: Legacy > Auto-discovery > Template defaults.

Workflow

Phase 1: Context Gathering (ONE TIME)

1.1 Auto-Discovery (scan project files):

Source	Data Extracted	Context Store Keys
package.json	name, description, dependencies, scripts, engines, author, contributors	PROJECT_NAME, PROJECT_DESCRIPTION, DEPENDENCIES, DEV_COMMANDS, DEVOPS_CONTACTS
docker-compose.yml	services, ports, deploy.replicas, runtime:nvidia	DOCKER_SERVICES, DEPLOYMENT_SCALE, HAS_GPU
Dockerfile	runtime version	RUNTIME_VERSION
src/ structure	folders, patterns	SRC_STRUCTURE, ARCHITECTURE_PATTERN
migrations/	table definitions	SCHEMA_OVERVIEW
.env.example	environment variables	ENV_VARIABLES
tsconfig.json, .eslintrc	conventions	CODE_CONVENTIONS
README.md	project description, scaling mentions	PROJECT_DESCRIPTION (fallback), DEPLOYMENT_SCALE (fallback)
CODEOWNERS	maintainers	DEVOPS_CONTACTS
git log	frequent committers	DEVOPS_CONTACTS (fallback)
~/.ssh/config, deploy targets	SSH aliases, hostnames, IPs	SERVER_INVENTORY
docker-compose VIRTUAL_HOST vars	domain routing	DOMAIN_DNS
.env.example registry URLs, .npmrc	artifact repos	ARTIFACT_REPOSITORY
docker-compose deploy.resources	resource limits	HOST_REQUIREMENTS

1.2 Detect Project Type:

Flag	Detection Rule
hasBackend	express/fastify/nestjs/fastapi/django in dependencies
hasDatabase	pg/mongoose/prisma/sequelize in dependencies OR postgres/mongo in docker-compose
hasFrontend	react/vue/angular/svelte in dependencies
hasDocker	Dockerfile exists OR docker-compose.yml exists

1.3 User Materials Request:

Ask: "Do you have existing materials (requirements, designs, docs)?"
If provided: Extract answers for Context Store

1.4 MCP Research (for detected technologies):

Use Context7/Ref for best practices
Store in Context Store for workers

1.5 Build Context Store:

{
  "PROJECT_NAME": "my-project",
  "PROJECT_DESCRIPTION": "...",
  "TECH_STACK": { "frontend": "React 18", "backend": "Express 4.18", "database": "PostgreSQL 15" },
  "DEPENDENCIES": [...],
  "SRC_STRUCTURE": { "controllers": [...], "services": [...] },
  "ENV_VARIABLES": ["DATABASE_URL", "JWT_SECRET"],
  "DEV_COMMANDS": { "dev": "npm run dev", "test": "npm test" },
  "DOCKER_SERVICES": ["app", "db"],
  "DEPLOYMENT_SCALE": "single",
  "DEVOPS_CONTACTS": [],
  "HAS_GPU": false,
  "SERVER_INVENTORY": [],
  "DOMAIN_DNS": [],
  "ARTIFACT_REPOSITORY": {},
  "HOST_REQUIREMENTS": {},
  "flags": { "hasBackend": true, "hasDatabase": true, "hasFrontend": true, "hasDocker": true }
}

DEPLOYMENT_SCALE detection rules:

"single" (default): No deploy.replicas, no scaling keywords in README
"multi": deploy.replicas > 1 OR load balancer mentioned
"auto-scaling": auto-scaling keywords in README/docker-compose
"gpu-based": runtime: nvidia in docker-compose

DEVOPS_CONTACTS fallback chain:

CODEOWNERS file → extract maintainers
package.json author/contributors → extract names/emails
git log → top 3 frequent committers
If all empty → [TBD: Provide DevOps team contacts]

1.6 Merge Legacy Content (if provided by ln-100):

Check if LEGACY_CONTENT was passed from ln-100 Phase 0

If exists, merge into Context Store:

contextStore.LEGACY_CONTENT = input.LEGACY_CONTENT

Merge priority for workers:
- LEGACY_CONTENT.legacy_architecture → used by ln-112 for architecture.md
- LEGACY_CONTENT.legacy_requirements → used by ln-112 for requirements.md
- LEGACY_CONTENT.legacy_tech_stack → merged with auto-discovered TECH_STACK
- LEGACY_CONTENT.legacy_principles → used by ln-111 for principles.md
- LEGACY_CONTENT.legacy_api → used by ln-113 for api_spec.md
- LEGACY_CONTENT.legacy_database → used by ln-113 for database_schema.md
- LEGACY_CONTENT.legacy_runbook → used by ln-115 for runbook.md
- LEGACY_CONTENT.legacy_infrastructure → used by ln-115 for infrastructure.md
If no LEGACY_CONTENT: workers use auto-discovery + template defaults

Phase 2: Delegate to Workers

2.1 Always invoke (parallel):

ln-111-root-docs-creator with Context Store
ln-112-project-core-creator with full Context Store
ln-115-devops-docs-creator with Context Store (infrastructure.md always; runbook.md internally conditional on hasDocker)

2.2 Conditionally invoke:

ln-113-backend-docs-creator if hasBackend OR hasDatabase
ln-114-frontend-docs-creator if hasFrontend

Delegation Pattern:

Pass Context Store and flags to workers via direct Skill tool invocation
Wait for completion
Collect result (created, skipped, tbd_count, validation)

Phase 3: Aggregate Results

Collect status from all workers
Sum totals: created files, skipped files, TBD markers
Report any validation warnings
Return aggregated summary to ln-100
Include Context Store for subsequent workers (ln-120 needs TECH_STACK)

Output:

{
  "workers_invoked": 5,
  "total_created": 11,
  "total_skipped": 0,
  "total_tbd": 8,
  "validation_status": "OK",
  "files": [
    "CLAUDE.md",
    "docs/README.md",
    "docs/documentation_standards.md",
    "docs/principles.md",
    "docs/project/requirements.md",
    "docs/project/architecture.md",
    "docs/project/tech_stack.md",
    "docs/project/api_spec.md",
    "docs/project/database_schema.md",
    "docs/project/design_guidelines.md",
    "docs/project/infrastructure.md",
    "docs/project/runbook.md"
  ],
  "context_store": {
    "PROJECT_NAME": "...",
    "TECH_STACK": { "frontend": "React 18", "backend": "Express 4.18", "database": "PostgreSQL 15" },
    "DEPENDENCIES": [...],
    "flags": { "hasBackend": true, "hasDatabase": true, "hasFrontend": true, "hasDocker": true }
  }
}

Critical Notes

Context gathered ONCE — never duplicated in workers
Context Store passed explicitly — no implicit state
Workers self-validate — coordinator only aggregates
Idempotent — workers skip existing files
Parallel where possible — ln-111 and ln-112 can run in parallel

Documentation Standards (passed to workers)

NO_CODE Rule: Documents describe contracts, not implementations
Stack Adaptation: Links must match TECH_STACK (Context Store)
Format Priority: Tables/ASCII > Lists > Text

Definition of Done

Context Store built with all discovered data
Project type flags determined
All applicable workers invoked
Results aggregated
Actuality verified: all document facts match current code (paths, functions, APIs, configs exist and are accurate)
Summary returned to ln-100

Phase 4: Meta-Analysis

MANDATORY READ: Load shared/references/meta_analysis_protocol.md

Skill type: planning-coordinator. Run after all phases complete. Output to chat using the planning-coordinator format.
