# ToolUniverse Router

Route user questions to specialized skills. If no skill matches, use general strategies from [references/general-strategies.md](references/general-strategies.md).

## Routing Workflow

1. **Extract keywords** from user's question
2. **Scan routing table** below for keyword matches
3. **Take action**:
   - **1 clear match** → invoke that skill NOW using the Skill tool
   - **Multiple matches** → ask user which they prefer (AskUserQuestion)
   - **No match** → use general strategies (load [references/general-strategies.md](references/general-strategies.md))
4. **If ambiguous** (e.g., "Tell me about aspirin") → ask user to clarify intent

**CRITICAL**: Actually INVOKE skills — don't describe them or show the routing table to the user.

**Language**: If the user writes in a non-English language, extract keywords for routing but respond in their language. All tool calls use English terms.

## Tie-Breaking Rules

1. **Domain Over Setup**: When "how do I", "help me", "explain", or "what is" co-occurs with a **domain entity** (drug, gene, protein, disease, variant, pathway name), route to the **domain skill**, NOT setup.
   - "how do I find interactions for TP53?" → protein-interactions
   - "help me research metformin" → drug-research
   - "what is EGFR?" → target-research
   - "I'm new, can you research diabetes?" → disease-research
   - Only route to setup when NO domain entity present ("how do I use this?")

2. **Specificity Rule**: More specific beats general.
   - "cancer treatment" → precision-oncology (not disease-research)

3. **Data Type Rule**: "get/retrieve/fetch" → retrieval skills.
   - "get compound structure" → chemical-compound-retrieval (not drug-research)

4. **Still ambiguous**: Ask user with AskUserQuestion.

## When to Use General Strategies

Only when no specialized skill matches:
- Meta-questions about ToolUniverse itself (no domain entity)
- Custom workflows combining multiple skills
- User explicitly says "don't use specialized skills"

**WARNING**: "how do I find interactions for TP53?" is NOT a meta-question — route to protein-interactions.

When using general strategies, load [references/general-strategies.md](references/general-strategies.md) and **execute** them (run actual queries, don't just describe).

## Routing Examples

**Clear match**: "comprehensive research report on breast cancer" → `Skill(skill="tooluniverse-disease-research", args="breast cancer")`

**Ambiguous**: "Tell me about aspirin" → AskUserQuestion: drug profile, safety, chemical data, or repurposing?

**No match**: "How can I find all tools related to proteomics?" → General strategies: run find_tools queries

**Domain + setup keyword**: "help me understand BRCA1 variants" → `Skill(skill="tooluniverse-variant-interpretation", args="BRCA1")`
