# Build Digital Twin Universes

## Directive
Create **simulated clones of all external services** (identity providers, issue trackers, databases, comms tools) so that autonomous AI agents can safely run end-to-end integration tests without touching live production environments.

## Suggested Targets
- Identity providers (Okta, Auth0)
- Issue trackers (Jira, Linear)
- Communication tools (Slack, Teams)
- Productivity suites (Google Docs, Notion)
- Databases and queues
- Customer-facing APIs

## Specific Steps
1. Inventory every external service the production system depends on.
2. Build behavioral clones (not just stubs) — they must respond like the real service across the relevant protocols.
3. Wire the agent's full integration test suite to run against the twins.
4. Validate twin fidelity periodically with contract tests against the real service.

## Expected Outcome
Autonomous agents can run unbounded integration tests safely, enabling [[concept-dark-factory|Dark Factory]] operation. See [[concept-digital-twin-universe]].
