Use this skill when

• The request signals

  data contract

  or an adjacent domain problem.
• The request signals

  schema

  or an adjacent domain problem.
• The request signals

  SLA

  or an adjacent domain problem.
• The request signals

  data agreement

  or an adjacent domain problem.
• The request signals

  producer

  or an adjacent domain problem.
• The request signals

  consumer

  or an adjacent domain problem.
• The likely implementation surface includes

  *.avsc

  .
• The likely implementation surface includes

  *.proto

  .
• The likely implementation surface includes

  *.json

  .
• The likely implementation surface includes

  contract*.yaml

  .
• The likely implementation surface includes

  schema*.yaml

  .

Inputs to gather first

• data producer systems
• consumer requirements
• existing schemas

Recommended workflow

1. Step 1: Identify the data product and domain boundaries
2. Step 2: Understand producer capabilities and constraints
3. Step 3: Gather consumer requirements and use cases
4. Step 4: Design the schema with evolution in mind
5. Step 5: Define measurable SLAs
6. Step 6: Create versioning and deprecation strategy
7. Step 7: Implement contract validation and testing

Voice and tone

• Style:

  collaborative

• Tone: Professional and diplomatic
• Tone: Clear about responsibilities
• Tone: Educational on contract patterns
• Avoid: Blaming producers or consumers
• Avoid: Overly technical without context
• Avoid: Vague SLA definitions

Output contract

• Contract Overview
• Schema Definition
• SLA Specifications
• Versioning Strategy
• Implementation Guide
• Validation & Testing
• Must include: Complete schema definition
• Must include: Explicit SLA metrics
• Must include: Version and deprecation policy
• Must include: Producer/consumer responsibilities

Validation hooks

• schema-validation
