Seed Expertise

Generate initial expertise file by exploring the codebase and building a mental model.

Arguments

• $1: Domain name (required, e.g., "database", "websocket")
• $ARGUMENTS: Focus areas (optional, e.g., "connection-pool queries migrations")

Instructions

You are seeding an expertise file by exploring the codebase and extracting domain knowledge.

Step 1: Parse Arguments

Extract:

• Domain name from $1 (required)
• Focus areas from remaining arguments

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

Step 2: Validate Expert Exists

Check if expert directory exists using Glob:

Glob: .claude/commands/experts/{$1}/*

If not found:

• STOP and report "Expert not found. Use /tac:create-expert to create it first."

Check if expertise already populated:

• Read .claude/commands/experts/{domain}/expertise.yaml
• If it has real content (not just placeholders), warn and ask to confirm overwrite

Step 3: Spawn Expertise-Seeder Agent

Delegate to the expertise-seeder agent with:

• Domain name
• Focus areas
• Output path: .claude/commands/experts/{domain}/expertise.yaml

The agent will:

1. Explore codebase for domain-related files
2. Analyze patterns and operations
3. Build YAML mental model structure
4. Enforce line limits
5. Write expertise file

Step 4: Validate and Report

After seeding completes:

## Expertise Seeded: {domain}

### Coverage

| Section | Entries |
| --- | --- |
| Core Implementation | X modules |
| Key Operations | X operations |
| Best Practices | X items |
| Known Issues | X items |

### File Stats

- Location: `.claude/commands/experts/{domain}/expertise.yaml`
- Lines: X/1000
- Valid YAML: Yes/No

### Next Steps

1. Review the generated expertise for accuracy
2. Run self-improve to validate: `/tac:improve-expertise {domain} false`
3. Test with a question: `/experts/{domain}/question "How does X work?"`

Quick Usage

# Seed with default exploration
/tac:seed-expertise database

# Seed with focus areas
/tac:seed-expertise database connection-pool queries migrations

# Seed websocket expert
/tac:seed-expertise websocket events hooks frontend-integration

Seeding Strategy

The expertise-seeder follows this approach:

1. Start Blank - Don't assume structure
2. Explore - Find relevant files and patterns
3. Build - Create YAML structure from findings
4. Validate - Ensure accuracy and completeness
5. Iterate - Run self-improve until stable

Notes

• Seeding creates the initial mental model
• Run self-improve after seeding to validate
• Mental model is NOT source of truth
• Stay under 1000 lines
• Focus areas help prioritize what to explore
