Want AI-powered acceptance criteria?
Codepylot uses Claude to generate context-aware acceptance criteria based on your codebase, tech stack, and existing patterns — then AI agents implement them automatically.

The Given/When/Then format (also known as Gherkin syntax) is the industry standard for writing clear, testable acceptance criteria for user stories.
The Three Parts
- Given — The precondition or starting context. What state is the system in?
- When — The action the user takes. What triggers the behavior?
- Then — The expected outcome. What should happen?
Best Practices
- Write from the user's perspective, not the developer's
- Cover the happy path, error cases, and edge cases
- Keep each criterion focused on one behavior
- Make criteria specific enough to test but general enough to allow implementation flexibility
- Aim for 3-5 criteria per story — more means the story should be split
Why AI Agents Love Given/When/Then
Autonomous coding agents (like those in Codepylot) perform significantly better when stories have clear Given/When/Then acceptance criteria. The structured format eliminates ambiguity and gives the agent concrete success conditions to implement against.
Frequently Asked Questions
What are acceptance criteria?
Acceptance criteria define the conditions that must be met for a user story to be considered complete. They specify the expected behavior of a feature, including success scenarios, error handling, and edge cases.
Why use Given/When/Then format?
Given/When/Then provides a structured, consistent format that is easy to read, write, and test. It separates the precondition (Given), action (When), and expected result (Then), making requirements unambiguous.
How many acceptance criteria should each story have?
Most stories should have 3-5 acceptance criteria. If you need more than 7, the story is likely too large and should be split into smaller stories.
Can AI agents use acceptance criteria?
Yes. AI coding agents perform much better with clear acceptance criteria. Codepylot's autonomous agents read the Given/When/Then criteria and implement each condition, resulting in higher-quality code with fewer review cycles.
