# Create ADRs for REST API Development

Guide stakeholders through a structured conversation to uncover and document technical decisions and functional requirements for REST API implementations. **This is an interactive SKILL**. The ADR is the documentation of that conversation, not the conversation itself.

**What is covered in this Skill?**

- Initial context: API purpose, consumers, constraints, load
- Functional requirements: use cases, resources, operations, response formats, error handling
- Technical decisions: language/framework, API design, auth/security, data, integration, infrastructure, testing, monitoring
- Decision synthesis and validation before ADR creation
- ADR document generation and next steps

## Constraints

Use conversational discovery—ask 1-2 questions at a time, build on answers, validate before proceeding. Only create ADR after thorough conversation and user confirmation.

- **MANDATORY**: Run `date` before starting to get accurate timestamps for the ADR
- **MUST**: Read the reference template fresh—do not use cached questions
- **MUST**: Ask one or two questions at a time; never all at once
- **MUST**: Validate summary with user ("Does this accurately capture your requirements?") before proposing ADR creation
- **MUST**: Wait for user to confirm "proceed" before generating the ADR
