Project Documentation Coordinator
Type: L2 Coordinator Category: 1XX Documentation Pipeline
Runtime-backed docs coordinator. The runtime owns context assembly checkpoints, conditional worker fan-out, and docs-generation summary aggregation.
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
- Builds the routing table used by
ln-100docs-quality repair loop
Runtime Contract
MANDATORY READ: Load references/coordinator_runtime_contract.md, references/docs_runtime_contract.md, references/docs_generation_summary_contract.md
Runtime family: docs-runtime
Identifier:
project-docs

PHASE_0_CONFIGPHASE_1_CONTEXT_ASSEMBLYPHASE_2_DETECTIONPHASE_3_DELEGATEPHASE_4_AGGREGATEPHASE_5_SELF_CHECK
Worker summary contract:
ln-111..115may receivesummaryArtifactPath- each worker writes or returns
docs-generationsummary envelope - ln-110 consumes worker summaries, not free-text worker prose
Invocation (who/when)
- ln-100-documents-pipeline: Invoked as first L2 coordinator in documentation pipeline
- Never called directly by users
Inputs
From ln-100 (optional source cleanup phase):
{
"SOURCE_DOC_NOTES": {
"architecture_notes": { "sections": [...], "diagrams": [...] },
"requirements_notes": { "functional": [...] },
"principles_notes": { "principles": [...], "anti_patterns": [...] },
"tech_stack_notes": { "frontend": "...", "backend": "...", "versions": {} },
"api_notes": { "endpoints": [...], "authentication": "..." },
"database_notes": { "tables": [...], "relationships": [...] },
"runbook_notes": { "prerequisites": [...], "install_steps": [...], "env_vars": [...] },
"infrastructure_notes": { "servers": [...], "domains": [...], "ports": {} }
}
}
SOURCE_DOC_NOTES enriches the standard context store before worker dispatch. Workers consume normalized context fields only; there is no legacy-specific override branch.
MANDATORY READ: Load references/docs_quality_contract.md.

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 Normalized Source Notes (if provided by ln-100):
- Check if
SOURCE_DOC_NOTESwas passed from ln-100 cleanup phase - If present, merge supporting facts into the standard Context Store:
contextStore.SOURCE_DOC_NOTES = input.SOURCE_DOC_NOTES - Enrichment intent:
- architecture notes strengthen architecture evidence
- requirement notes strengthen requirements evidence
- tech-stack notes clarify versions and rationale
- principles, API, database, runbook, and infrastructure notes provide supplemental factual input
- Workers always generate from normalized context + current project sources
- If no
SOURCE_DOC_NOTESare present: rely on direct auto-discovery + current canonical docs
Phase 2: Delegate to Workers
MANDATORY: All applicable workers MUST be invoked. Workers run in parallel via Agent tool for context isolation.
2.1 Always invoke (parallel):
ln-111-root-docs-creatorwith Context Storeln-112-project-core-creatorwith full Context Storeln-115-devops-docs-creatorwith Context Store (infrastructure.md always; runbook.md internally conditional on hasDocker)
2.2 Conditionally invoke:
ln-113-backend-docs-creatorif hasBackend OR hasDatabaseln-114-frontend-docs-creatorif hasFrontend
Invocation (parallel via Agent tool):
Agent(description: "{doc_type} docs via {worker}",
prompt: "Invoke Skill(skill: \"{worker}\") with context below.\n\nCONTEXT: {contextStore}",
subagent_type: "general-purpose")
Delegation Rules:
- Pass Context Store and flags to workers via Agent+Skill pattern
- Wait for all Agent completions
- Collect normalized result (
created_files,skipped_files,quality_inputs,validation_status)
Phase 3: Aggregate Results
- Col
