What does an AI coding PRD generator create?

An AI coding PRD generator turns a feature idea into a structured markdown requirement with user context, scope, constraints, stories, acceptance criteria, and review notes. The result is meant to be reviewed by a developer before it becomes input for Hal or an AI coding agent.

How to use the PRD generator

Describe the feature, the user, the desired behavior, constraints, and the technology context. The generator turns those inputs into a markdown PRD with sections that are easier to inspect before running an agent loop.

Why this helps AI coding workflows

Broad prompts create broad changes. A PRD gives the agent a narrower target and gives the developer a document to review before implementation begins.

What to check before running Hal

Confirm the PRD names the user, defines in-scope and out-of-scope behavior, includes acceptance criteria, and calls out risky areas such as authentication, payments, migrations, permissions, or data loss.

Generate the PRD, run it through the PRD Readiness Checker, split risky work into smaller stories, then use the final markdown as the source for a small Hal loop.

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 does the PRD generator create?

It creates a markdown PRD with problem statement, scope, constraints, user stories, acceptance criteria, review notes, and a suggested Hal planning prompt.

Can I use the generated PRD outside Hal?

Yes. The PRD is plain markdown and can be used with a human developer, an AI coding agent, or Hal's PRD-driven loop.

Should I review the generated PRD?

Yes. Treat it as a draft. Confirm scope, edge cases, and acceptance criteria before handing the work to an agent.

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.
