SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps implement a specific phase of a software specification, ensuring all tasks and verification steps are completed before moving forward.

Core Features & Use Cases

  • Phase Implementation: Executes tasks defined within a specific phase of a spec file.
  • Verification: Ensures all success criteria, including tests and lint checks, are met.
  • Use Case: When a spec outlines a new feature broken into phases, this Skill can be used to implement and verify each phase sequentially.

Quick Start

Use the implement-spec skill to implement phase 3 of the attached spec file.

FAQPage Schema
How do I implement a specific phase of a software specification?

To implement a specific phase of a software specification, execute the defined tasks sequentially and complete all verification steps before committing changes. This ensures all success criteria, including tests and lint checks, are met for that phase.

What is spec-driven iterative development?

Spec-driven iterative development is a workflow where features are broken down into distinct, verifiable phases. It requires a thorough understanding of the spec and associated documentation to implement and verify each phase sequentially before moving forward.

How do I verify success criteria when implementing a spec phase?

You verify success criteria when implementing a spec phase by applying required tests and lint checks. The implementation process ensures all verification steps are completed and validated before changes are committed and the next phase begins.

Do I need associated documentation to implement a spec phase?

Yes, you need associated documentation to implement a spec phase. Thorough understanding of the spec file and all related documentation is required to correctly execute tasks and adhere to implementation and verification steps.

When should I use a phased implementation approach for coding?

You should use a phased implementation approach for coding when a specification outlines a new feature broken into distinct, verifiable phases. This ensures all tasks and verification steps within each phase are completed before moving forward.
