What does an acceptance criteria generator do?

An acceptance criteria generator turns a feature idea into observable conditions for accepting generated code. It helps developers define expected behavior, edge cases, and review checks before implementation starts, so an AI coding loop has a clearer target than a vague natural-language request.

How to use the acceptance criteria generator

Enter a feature idea, user role, application type, expected success behavior, and likely failure modes. The tool returns criteria in a format that can be pasted into a PRD, issue, or story.

Why acceptance criteria matter

Agent loops are easier to review when each story has a clear definition of done. Acceptance criteria keep the work grounded in observable behavior rather than vague intent.

What good criteria prevent

They reduce arguments with the agent after the fact. Instead of asking whether a change “looks right,” the reviewer can check whether the expected behavior, edge cases, and failure states were handled.

Generate criteria first, add them to a PRD or task-splitting workflow, then run implementation only after the story is small enough to review.

How this tool fits the Hal workflow

Use this tool before a coding agent edits files. Then move from tool output into PRD-driven planning, a first Hal loop, or a review-before-merge checklist. Treat generated text as a draft and verify it against the repository before use.

Verification rule

Before adopting Hal, inspect the source repository, install guide, pricing page, and machine-readable pricing. This tool does not guarantee code quality, test success, or merge safety.

FAQ

Short answers before you hand the output to an agent workflow.

What are good acceptance criteria for AI coding?

Good acceptance criteria are observable, testable, and tied to user behavior. They tell the agent what done means and tell the reviewer what to inspect.

Does this replace QA?

No. It produces a checklist for implementation and review. Developers still need to test and inspect the actual changes.

Can I add these criteria to a Hal PRD?

Yes. Copy the generated criteria into a PRD or use the PRD generator to produce a fuller markdown document.

Next step

Use the output in a Hal loop

Hal is a terminal-first CLI for PRD-native coding loops. Use the generated markdown as planning input, keep the work bounded, and review agent output before merging.
