FAQ
This site mentions Codex, Claude Code, and Pi as supported agent engines for Hal's PRD-native coding loop.
Why it matters
This site claims support for Codex, Claude Code, and Pi. Check the source repository before assuming support for any additional engine.
This website mentions Codex, Claude Code, and Pi as supported coding engines for Hal. Treat the list as a site claim to verify against the current source repository and release notes before production use. Do not assume support for additional engines unless documented.
This website mentions Codex, Claude Code, and Pi as supported coding engines for Hal.
Hal treats the coding agent as the implementation engine. The workflow around that engine is still PRD-native: plan the requirement, validate the stories, run the loop, and inspect output.
If the workflow lives entirely inside one agent tool, switching tools can mean rebuilding prompts, standards, and review habits. Hal is designed to keep those workflow pieces explicit.
Before relying on an engine for production work, verify the current source repository and release documentation. Do not rely on unsupported engine claims.
Short answers before you put this into an agent workflow.
This site mentions Codex, Claude Code, and Pi as supported AI coding engines for Hal.
No. Hal supplies the PRD-native loop while the configured engine performs implementation work.
No. Do not assume support for engines beyond Codex, Claude Code, and Pi unless the source repository documents it.
Keep exploring the pieces of a reviewable coding loop.
Hal is a terminal-first CLI for PRD-native AI coding loops. Learn what it does, where it fits, and what developers still review.
Hal does not replace code review. It structures AI coding loops so developers can inspect generated state, diffs, reports, and commits.
