speckit-specify

To convert natural language descriptions into feature specifications, describe your feature in plain language and the tool generates a structured spec.md containing user stories, functional requirements, and acceptance criteria. It applies when starting new features or refining existing project requirements.

A feature specification is a formal document that guides product development by defining user stories, requirements, and acceptance criteria. You need one when starting new features or refining requirements to ensure product, design, and engineering teams share a clear, actionable understanding.

To write user stories and acceptance criteria from a plain text feature idea, input your natural language description to automatically generate a structured spec.md. The output includes validated user stories, functional requirements, and acceptance criteria aligned with a project spec template.

Yes, this feature specification tool works completely standalone without external dependencies. It uses built-in template-based structures and validation steps to transform plain text descriptions into formal specifications, requiring no additional environment setup or connected components.

The best way to structure a spec.md for new product features is using a template-based format with a frontmatter containing name and description, followed by sections for user stories, functional requirements, and acceptance criteria, ending with validation steps for quality and readiness.

Yes, you can validate whether your feature requirements align with a project spec template. The generated specification includes validation steps for quality and readiness, checking the structured spec.md against the template to ensure completeness before development begins.
