READMESKILL.md - Create Specification
# Create Specification Your goal is to create a new specification file for `${input:SpecPurpose}`. The specification file must define the requirements, constraints, and interfaces for the solution components in a manner that is clear, unambiguous, and structured for effective use by Generative AIs. Follow established documentation standards and ensure the content is machine-readable and self-contained. ## Best Practices for AI-Ready Specifications - Use precise, explicit, and unambiguous language. - Clearly distinguish between requirements, constraints, and recommendations. - Use structured formatting (headings, lists, tables) for easy parsing. - Avoid idioms, metaphors, or context-dependent references. - Define all acronyms and domain-specific terms. - Include examples and edge cases where applicable. - Ensure the document is self-contained and does not rely on external context. The specification should be saved in the [/spec/](/spec/) directory and named according to the following convention: `spec-[a-z0-9-]+.md`, where the name should be descriptive of the specification's content and starting with the highlevel purpose, which is one of [schema, tool, data, infrastructure, process, architecture, or design]. The specification file must be formatted in well formed Markdown. Specification files must follow the template below, ensuring that all sections are filled out appropriately. The front matter for the markdown should be structured correctly as per the example following: ```md --- title: [Concise Title Describing the Specification's Focus] version: [Optional: e.g., 1.0, Date] date_created: [YYYY-MM-DD] last_updated: [Optional: YYYY-MM-DD] owner: [Optional: Team/Individual responsible for this spec] tags: [Optional: List of relevant tags or categories, e.g., `infrastructure`, `process`, `design`, `app` etc] --- # Introduction [A short concise introduction to the specification and the goal it is intended to achieve.] ## 1. Purpose & Scope [Provide a clear, concise description of the specification's purpose and the scope of its application. State the intended audience and any assumptions.] ## 2. Definitions [List and define all acronyms, abbreviations, and domain-specific terms used in this specification.] ## 3. Requirements, Constraints & Guidelines [Explicitly list all requirements, constraints, rules, and guidelines. Use bullet points or tables for clarity.] - **REQ-001**: Requirement 1 - **SEC-001**: Security Requirement 1 - **[3 LETTERS]-001**: Other Requirement 1 - **CON-001**: Constraint 1 - **GUD-001**: Guideline 1 - **PAT-001**: Pattern to follow 1 ## 4. Interfaces & Data Contracts [Describe the interfaces, APIs, data contracts, or integration points. Use tables or code blocks for schemas and examples.] ## 5. Acceptance Criteria [Define clear, testable acceptance criteria for each requirement using Given-When-Then format where appropriate.] - **AC-001**: Given [context], When [action], Then [expected outcome] - **AC-002**: The system shall [specific behavior] when [condition] - **AC-003**: [Additional acceptance criteria as needed] ## 6. Test Automation Strategy [Define the testing approach, frameworks, and automation requirements.] - **Test Levels**: Unit, Integration, End-to-End - **Frameworks**: MSTest, FluentAssertions, Moq (for .NET applications) - **Test Data Management**: [approach for test data creation and cleanup] - **CI/CD Integration**: [automated testing in GitHub Actions pipelines] - **Coverage Requirements**: [minimum code coverage thresholds] - **Performance Testing**: [approach for load and performance testing] ## 7. Rationale & Context [Explain the reasoning behind the requirements, constraints, and guidelines. Provide context for design decisions.] ## 8. Dependencies & External Integrations [Define the external systems, services, a
