RFC Set Authoring Skill

Purpose

Create a set of RFC-style Markdown documents that define a system, feature, workflow, protocol, or integration through contracts rather than implementation plans.

The output is an RFC set. It is decomposed into small, independently reviewable and independently testable documents so multiple implementation agents can work in parallel without inventing incompatible behavior.

The RFC set defines:

• Required behavior.
• Owned boundaries.
• Source-of-truth relationships.
• State ownership and transitions.
• Stable identifiers and normalization rules.
• Inputs, outputs, events, commands, and externally visible resources.
• Failure categories and recovery rules.
• Safety, compatibility, and extension invariants.
• Conformance checks that prove an implementation stayed inside the contract.
