external-tool-coordination SKILL.md skillA
external-tool-coordination from a5c-ai/babysitter is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add a5c-ai/babysitter/external-tool-coordination@git:20260601.da7723aPins git:20260601.da7723a in mdr.lock. Pin the fingerprint instead.

Coordinate external AI tool integration (OpenAI Codex, Google Gemini) for cross-model adversarial review and delegated implementation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
- 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
Invoke as part of: `methodologies/metaswarm/metaswarm-swarm-coordinator`Read the whole file at its exact version.
How to install
mdr add a5c-ai/babysitter/external-tool-coordination@sha256:6690fa500143bc5aThe line at the top of this page pins the label git:20260601.da7723a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
