description: Coordinate external AI tool integration (OpenAI Codex, Google Gemini) for cross-model adversarial review and delegated implementation.

allowed-tools: Read, Write, Edit, Bash, Grep, Glob, WebFetch, WebSearch, Agent, AskUserQuestion

skillAreas: [skill-area:agentic-loops, skill-area:orchestration-loop]

workflows: [workflow:feature-development]

topics: [topic:developer-experience]

roles: [role:tech-lead, role:backend-engineer]

- For cross-model adversarial review (writer reviewed by different model)

- When delegating implementation to cheaper external models

- For escalation chains across tools

## Capabilities

- **Delegated Implementation** - Send work units to external AI tools for implementation

- **Cross-Model Review** - Implementation by Model A, adversarial review by Model B

- **Escalation Chains** - Tool A -> Tool B -> Claude -> human

- **Cost Optimization** - Route simpler tasks to cheaper models

## Configuration

Requires `.metaswarm/external-tools.yaml`:

```yaml

tools:

- name: codex

type: openai

capabilities: [implement, review]

- name: gemini

type: google

capabilities: [implement, review]

escalation:

chain: [codex, gemini, claude, human]

```

## Agents Used

- `agents/swarm-coordinator/` - Multi-tool orchestration

## Tool Use
