ranbot-ai DDD Context Mapping
Use this skill when
- Defining integration patterns between bounded contexts.
- Preventing domain leakage across service boundaries.
- Planning anti-corruption layers during migration.
- Clarifying upstream and downstream ownership for contracts.
Do not use this skill when
- You have a single-context system with no integrations.
- You only need internal class design.
- You are selecting cloud infrastructure tooling.
Instructions
- List all context pairs and dependency direction.
- Choose relationship patterns per pair.
- Define translation rules and ownership boundaries.
- Add failure modes, fallback behavior, and versioning policy.
If detailed mapping structures are needed, open references/context-map-patterns.md.
Output requirements
- Relationship map for all context pairs
- Contract ownership matrix
- Translation and anti-corruption decisions
- Known coupling risks and mitigation plan
Examples
Use @ddd-context-mapping to define how Checkout integrates with Billing,
Inventory, and Fraud contexts, including ACL and contract ownership.
Limitations
- This skill does not replace API-level schema design.
- It does not guarantee organizational alignment by itself.
- It should be revisited when team ownership changes.
