## Model Configuration

Agents are assigned to specific Claude models based on task complexity and computational requirements.

### Model Distribution Summary

| Model   | Agent Count | Use Case                                                        |
| ------- | ----------- | --------------------------------------------------------------- |
| Fable   | 0           | Longest-horizon autonomous work (tier above Opus; see criteria) |
| Opus    | 55          | Critical architecture, security, code review, production coding |
| Sonnet  | 71          | Complex tasks, support with intelligence                        |
| Haiku   | 25          | Fast operational tasks                                          |
| Inherit | 52          | Complex tasks where the user chooses the model at runtime       |

### Model Selection Criteria

#### Haiku - Fast Execution & Deterministic Tasks

**Use when:**

- Generating code from well-defined specifications
- Creating tests following established patterns
- Writing documentation with clear templates
- Executing infrastructure operations
- Performing database query optimization
- Handling customer support responses
- Processing SEO optimization tasks
- Managing deployment pipelines

#### Sonnet - Complex Reasoning & Architecture

**Use when:**

- Designing system architecture
- Making technology selection decisions
- Performing security audits
- Reviewing code for architectural patterns
- Creating complex AI/ML pipelines
- Providing language-specific expertise
- Orchestrating multi-agent workflows
- Handling business-critical legal/HR matters

#### Fable - Longest-Horizon Autonomous Work

Claude Fable 5 (`model: fable`) is the tier above Opus. It is opt-in in Claude Code
(v2.1.170+, never the default) and carries roughly 2.6× the effective cost of Opus
($10/$50 per MTok plus a ~30% heavier tokenizer), so reserve it for agents where Opus
demonstrably needs multiple attempts.

**Use when:**

- Running multi-hour autonomous sessions (large codebase migrations, overnight refactors)
- Executing end-to-end work from a single well-specified goal
- Coordinating long-lived parallel sub-agent workstreams

**Avoid for:**

- Security-analysis agents — Fable 5's cyber/bio safety classifiers fall back to
  Opus 4.8 on that content anyway
- Anything Sonnet or Opus already completes in one pass

Other harnesses map `fable` to their top available model (see
[authoring.md](authoring.md#model-aliases)). Fable-tier agent bodies should state goals
and constraints rather than step-by-step scaffolding, and must not ask the model to echo
its internal reasoning.

### Hybrid Orchestration Patterns

The plugin ecosystem leverages Sonnet + Haiku orchestration for optimal performance and cost efficiency:

#### Pattern 1: Planning → Execution

```
Sonnet: backend-architect (design API architecture)
  ↓
Haiku: Generate API endpoints following spec
  ↓
Haiku: test-automator (generate comprehensive tests)
  ↓
Sonnet: code-reviewer (architectural review)
```

#### Pattern 2: Reasoning → Action (Incident Response)

```
Sonnet: incident-responder (diagnose issue, create strategy)
  ↓
Haiku: devops-troubleshooter (execute fixes)
  ↓
Haiku: deployment-engineer (deploy hotfix)
  ↓
Haiku: Implement monitoring alerts
```

#### Pattern 3: Complex → Simple (Database Design)

```
Sonnet: database-architect (schema design, technology selection)
  ↓
Haiku: sql-pro (generate migration scripts)
  ↓
Haiku: database-admin (execute migrations)
  ↓
Haiku: database-optimizer (tune query performance)
```

#### Pattern 4: Multi-Agent Workflows

```
Full-Stack Feature Development:
Sonnet: backend-architect + frontend-developer (design components)
  ↓
Haiku: Generate code following designs
  ↓
Haiku: test-automator (unit + integration tests)
  ↓
Sonnet: security-auditor (security review)
  ↓
Haiku: deployment-engineer (CI/CD setup)
  ↓
Haiku: Setup observability stack
```

## Agent Invocation

### Natural Language

Agents can be invoked through natural language when you need Claude to reason about which specialist to use:

```
"Use backend-architect to design the authentication API"
"Have security-auditor scan for OWASP vulnerabilities"
"Get performance-engineer to optimize this database query"
```

### Slash Commands

Many agents are accessible through plugin slash commands for direct invocation:

```bash
/backend-development:feature-development user authentication
/security-scanning:security-sast
/incident-response:smart-fix "memory leak in payment service"
```

## Contributing

To add a new agent:

1. Create `plugins/{plugin-name}/agents/{agent-name}.md`
2. Add frontmatter with name, description, and model assignment
3. Write comprehensive system prompt
4. Update plugin definition in `.claude-plugin/marketplace.json`

See [Contributing Guide](../CONTRIBUTING.md) for details.
