# ML Engineer Orchestrator

**Communication: User's language. Code: English.**

## Purpose

Routes AI/ML tasks to specialized sub-skills. Orchestrates LLM integration, RAG, operations, agents, and multimodal AI.

## Context Discovery

### Auto-Investigation

Check for existing AI/ML setup:

| Signal | How to Check | What It Tells Us |
|--------|--------------|------------------|
| `openai` in dependencies | `Grep("openai", "**/requirements.txt")` | OpenAI SDK used |
| `anthropic` in dependencies | `Grep("anthropic", "**/requirements.txt")` | Claude SDK used |
| `langchain` in dependencies | `Grep("langchain", "**/requirements.txt")` | LangChain framework |
| `llamaindex` in dependencies | `Grep("llama-index", "**/requirements.txt")` | LlamaIndex framework |
| Vector DB config | `Grep("qdrant\|chroma\|pinecone\|weaviate", "**/*")` | Vector DB setup exists |
| Embedding models | `Grep("embed\|embedding", "**/*.py")` | Embeddings used |
| `.env` with API keys | `Grep("OPENAI_API_KEY\|ANTHROPIC_API_KEY", "**/.env*")` | Which APIs configured |

### Discovery Questions

Use `AskUserQuestion` to understand AI/ML requirements.

#### Q1: AI/ML Goal

```yaml
question: "What do you want to achieve with AI/ML?"
header: "Goal"
multiSelect: false
options:
  - label: "Use LLM APIs (chat, generation)"
    description: "Integrate OpenAI, Claude, or Gemini"
  - label: "Build RAG system (knowledge base)"
    description: "Search and retrieve from documents"
  - label: "Create AI agent (autonomous tasks)"
    description: "Agent that uses tools and reasons"
  - label: "Fine-tune a model"
    description: "Train model on custom data"
  - label: "Add vision/image/voice"
    description: "Multimodal AI capabilities"
```

**Routing:**
- "LLM APIs" → `Skill(faion-llm-integration)`
- "RAG system" → `Skill(faion-rag-engineer)`
- "AI agent" → `Skill(faion-ai-agents)`
- "Fine-tune" → `Skill(faion-ml-ops)`
- "Multimodal" → `Skill(faion-multimodal-ai)`

#### Q2: LLM Provider Preference (if LLM task)

```yaml
question: "Which LLM provider do you prefer?"
header: "Provider"
multiSelect: false
options:
  - label: "OpenAI (GPT-4)"
    description: "Best general purpose, good tools support"
  - label: "Anthropic (Claude)"
    description: "Best for long context, reasoning, safety"
  - label: "Google (Gemini)"
    description: "Multimodal, 2M context, grounding"
  - label: "Local (Ollama)"
    description: "Privacy, no API costs, offline"
  - label: "Not sure / recommend"
    description: "I'll suggest based on your use case"
```

#### Q3: Data Situation (if RAG or fine-tuning)

```yaml
question: "What data do you have?"
header: "Data"
multiSelect: true
options:
  - label: "Documents (PDF, markdown, text)"
    description: "Unstructured text content"
  - label: "Structured data (database, CSV)"
    description: "Tabular or relational data"
  - label: "Code repositories"
    description: "Source code to search/understand"
  - label: "Conversation logs"
    description: "Chat history, support tickets"
```

**Routing:**
- "Documents" → RAG with chunking strategies
- "Structured data" → Text-to-SQL or structured RAG
- "Code repos" → Code embeddings, AST-aware chunking
- "Conversations" → Fine-tuning dataset prep

#### Q4: Deployment Requirements

```yaml
question: "How will this be deployed?"
header: "Deploy"
multiSelect: false
options:
  - label: "API endpoint (backend service)"
    description: "Part of web application"
  - label: "CLI tool"
    description: "Command-line interface"
  - label: "Batch processing"
    description: "Process data in bulk"
  - label: "Real-time/streaming"
    description: "Live interactions, low latency"
```

**Context impact:**
- "API endpoint" → Async patterns, rate limiting, caching
- "CLI tool" → Simple integration, local models option
- "Batch processing" → Cost optimization, parallel processing
- "Real-time" → Streaming responses, edge deployment
