Reviewable AI coding loop

A reviewable AI coding loop is an agent-assisted workflow that leaves inspectable requirements, changes, reports, and checkpoints before merge.

Why it matters

A reviewable AI coding loop keeps agent work bounded, attributable, and inspectable instead of letting implementation disappear into a chat transcript.

What is a reviewable AI coding loop?

A reviewable AI coding loop is a workflow where an AI coding agent works on a bounded task and leaves enough evidence for a developer to inspect the result. In Hal, that evidence can include PRD context, stories, validation state, reports, changed files, commits, and archive behavior.

Why reviewability matters

Agent output can look plausible while missing product intent, edge cases, local standards, or security concerns. Reviewability does not make the output correct by itself. It makes the decision easier because the developer can compare the diff against the requirement and acceptance criteria.

Example workflow

hal plan "add account settings with one saved preference"
hal convert
hal validate
hal run

A healthy loop has a checkpoint before hal run and another checkpoint after implementation. The first checkpoint reviews scope. The second reviews behavior, tests, changed files, and unresolved criteria.

Reviewable vs unreviewable agent work

Reviewable loopUnreviewable session
Starts from a PRD or scoped requirement.Starts from a broad prompt.
Splits work into stories with acceptance criteria.Lets scope expand inside the chat.
Preserves state, reports, and changed files.Leaves decisions buried in conversation history.
Requires developer review before merge.Treats completion as permission to merge.

How Hal applies the term

Hal is a terminal-first CLI for PRD-native coding loops. It treats the configured engine as the implementation worker while the loop supplies planning, validation, execution, reports, archive state, and review points.

Verification rule

Before adopting Hal, verify the current source repository, install guide, release notes, and documented engine support.

FAQ

Short answers before you put this into an agent workflow.

What makes an AI coding loop reviewable?

It leaves clear requirements, scoped stories, changed files, reports, commits or workflow state, and a human checkpoint before merge.

Does reviewable mean automatically safe?

No. Reviewable means easier to inspect. A developer still needs to test and decide whether to merge.
