Free tools
Prepare the work before an AI coding agent touches your repo. Check PRDs, generate acceptance criteria, write AGENTS.md instructions, and split risky tasks into reviewable stories.
analyzer
Check whether a product requirement is specific enough for an AI coding loop before an agent touches the repo.
generator
Generate a markdown PRD, user stories, acceptance criteria, and a Hal-ready planning prompt from a feature idea.
generator
Turn a feature idea into testable Given/When/Then acceptance criteria, edge cases, and a review checklist.
generator
Generate repo-specific AGENTS.md instructions for Codex, Claude Code, Pi, and other AI coding workflows.
analyzer
Break a feature request into reviewable implementation stories and score whether it is safe for an AI coding loop.
AI coding works better when the task is specific, bounded, and easy to review. These tools turn vague intent into PRDs, acceptance criteria, project standards, and story-sized implementation plans before an agent edits code.
Hal is a terminal-first CLI for PRD-native coding loops. Use the generated markdown as source material, run a small loop, and inspect the resulting commits, reports, and changed files before merging.
