# CI Reviewer Bot

This tutorial shows how to build a CI reviewer bot that runs an Autohand agent on every pull request and posts the review as a comment.

## What you will build

-   A GitHub Actions workflow that triggers on pull requests.
-   An Autohand agent that reviews changed files.
-   A script that posts the review back to GitHub.

## Prerequisites

-   A GitHub repository with Actions enabled.
-   An Autohand API key stored as `AUTOHAND_API_KEY`.
-   A GitHub token with pull request comment permissions.

## Step 1: create the workflow

## Step 2: post the review

The `post-review.js` script reads the agent output and creates a PR comment.

## Step 3: tune the prompt

Iterate on the prompt to match your team's review style. Include context such as coding standards, test expectations, and areas to ignore.

## Next steps

Add a check that fails the build when the agent finds blocking issues, or extend the bot to suggest code changes.
