Query Expert

Ask an agent expert a question, getting answers grounded in its expertise mental model.

Arguments

• $1: Domain name (required, e.g., "database", "websocket")
• Remaining arguments after $1: Your question (required)

Note: Extract the question by removing the domain name from $ARGUMENTS, or use $2, $3, etc. to capture question words.

Instructions

You are querying an agent expert to get answers based on its domain expertise.

Step 1: Parse Arguments

Extract:

• Domain name from $1 (required)
• Question from remaining arguments (required)

If no domain provided, STOP and ask for domain name. If no question provided, STOP and ask for the question.

Step 2: Validate Expert Exists

Check if expertise file exists and has content using the Read tool:

Read: .claude/commands/experts/{$1}/expertise.yaml

If not found or empty:

• STOP and report "Expert not found or not seeded."
• Suggest: /tac:create-expert {domain} or /tac:seed-expertise {domain}

Step 3: Load Expertise

Read the expertise file:

• Parse YAML structure
• Understand the mental model
• Note coverage areas

Step 4: Answer Question

Using the expertise as your knowledge base:

1. Identify relevant sections
2. Extract pertinent information
3. Validate against codebase if needed (read actual files)
4. Formulate answer

Step 5: Report

## {Domain} Expert Response

### Question

{question}

### Answer

{Your answer based on expertise}

### Sources

- **Expertise sections used:** [list]
- **Files referenced:** [list if any]

### Confidence: [High/Medium/Low]

{Explanation of confidence level}

### If Low Confidence

The expertise file may need updating. Run:

```bash
/tac:improve-expertise {domain} false

Quick Usage

# Ask database expert
/tac:query-expert database "How does connection pooling work?"

# Ask websocket expert
/tac:query-expert websocket "What events are available?"

# Ask about specific operation
/tac:query-expert database "How do I batch insert records?"

Confidence Levels

Level	Meaning
High	Expertise directly covers this topic
Medium	Expertise partially covers, some inference needed
Low	Expertise doesn't cover well, recommend self-improve

Notes

• Answers are grounded in the expertise mental model
• If expertise seems outdated, recommend self-improve
• Mental model is NOT source of truth - validate against code when uncertain
• This is the REUSE step of Act-Learn-Reuse
