SYSTEM DOCUMENTATION & REQUIREMENTS

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.

Frequently Asked Questions about plane

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I coordinate database schema migrations with API and UI changes safely?

Coordinate cross-boundary changes by sequencing rollout phases from addition to enforcement, ensuring old and new states remain safe throughout the migration. This approach traces the user-visible result backward through API, data, and UI layers to prevent failures at handoffs.

What is end-to-end reasoning for software changes that cross multiple service boundaries?

End-to-end reasoning maps a final user-visible outcome backward through every technical boundary and release state. It defines rules for data shape, ownership, and failure behavior at each handoff to prove the smallest complete path works across UI, API, service, and infrastructure layers.

How do I plan a safe rollout sequence for changes spanning infrastructure and observability layers?

Plan a safe rollout by ordering phases for addition, migration, enforcement, and removal. This ensures compatibility across infrastructure and observability layers while verifying the smallest full path needed to prove the result remains correct at every release state.

When do I need cross-domain proof for software migrations across system boundaries?

Cross-domain proof is needed when a result spans UI, API, services, data, or infrastructure boundaries and no single domain can prove the whole outcome alone. It identifies the smallest full path to test, focusing on the weakest links where meaning or guarantees can fail at handoffs.

Can I use this approach to manage changes across payment services and checkout flows?

Yes, this approach manages changes across payment services and checkout flows by mapping the final user-visible result back through every boundary. It coordinates checkout flow, payment service behavior, and database schema changes so the outcome remains correct throughout rollout.

What boundary rules are required for safe end-to-end changes across API and service layers?

Required boundary rules define meaning, data shape, ownership, compatibility, retries, idempotency, and failure behavior at each handoff. Setting these rules across API and service layers ensures guarantees do not fail during release states and cross-domain migrations.
