What problem does it solve?
This Skill helps when a result must work across multiple technical boundaries, such as UI, API, services, data, infrastructure, or observability, and no single domain can prove the whole outcome by itself.
Core Features & Use Cases
- End-to-End Reasoning: Starts from the final visible result and works backward through every boundary and release state.
- Boundary Rule Setting: Defines meaning, data shape, ownership, compatibility, retries, idempotency, and failure behavior at each handoff.
- Safe Rollout Planning: Sequences addition, migration, enforcement, and removal so old and new states stay safe.
- Cross-Domain Proof: Identifies the smallest full path needed to prove the result and focuses testing on the weakest links.
- Use Case: A product team is changing checkout flow, payment service behavior, and database schema together; this Skill helps coordinate the change so the user-visible outcome remains correct throughout rollout.
Quick Start
Use the plane skill to map this change from the final user-visible result back through every boundary, release state, and required proof.
