What it does

When installed, the agent follows a fixed template to write a specification document for a software solution: purpose, requirements, interfaces, acceptance criteria, test strategy and more. The spec is written in precise, structured Markdown designed so that other AI tools can parse and implement it, and it is saved into a /spec/ folder using a naming convention. The skill is instructions only; it contains no scripts and does not reach the internet.

Great for

  • Developers who want an AI-friendly requirements document before building a feature or component
  • Teams that hand off work to AI coding agents and need self-contained, unambiguous specs
  • Students learning how formal software specifications are structured

Skip it if

  • Quick notes or informal planning, since the template is long and formal and may be heavier than needed
  • Non-software projects, because the template assumes a solution with interfaces, APIs and tests (its test section defaults to .NET tools such as MSTest and Moq)
  • Replacing human review: the generated spec reflects the agent's assumptions and still needs checking by someone who knows the system

Try asking

  • “Create a specification for a user login and password reset feature”
  • “Write a spec for a nightly data import tool that reads CSV files from an SFTP server”
  • “Draft an architecture spec describing how our payment service integrates with external providers”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Describe the solution's purpose clearly when invoking the skill, since the spec filename and content depend on it
  • Edit the .NET-specific test framework defaults if your project uses another stack
  • Review the generated acceptance criteria and constraints against your real requirements before relying on them
