PR Bot: AI-Powered PR Reviews for Azure DevOps, GitHub & Bitbucket

Lokesh — Sun, 22 Feb 2026 23:32:15 +0000

In short: prbot is a CLI that uses Claude, GPT, or Cursor to review pull requests on Azure DevOps, GitHub, or Bitbucket. It posts structured feedback as PR comments, including inline feedback on specific lines. Configure once, run prbot review 42, and get AI-powered code reviews aligned with your team's standards.

Code reviews are critical for software quality — but they’re often slow, repetitive, and inconsistent.

What if a CLI tool could:

Fetch your PR
Apply your team’s coding standards
Send everything to Claude, GPT, or Cursor
Post structured feedback directly on the PR

That’s what prbot does.

prbot does exactly that. It's a lightweight CLI that fetches PR metadata and diffs from your source control platform, sends them to an AI (Claude, GPT, or Cursor), and posts the review as comments—including inline feedback on specific lines.

Why prbot?

How It Works

prbot fetches PR metadata and diffs from your source control platform.
It loads your CodeStandard.md.
It sends structured input to the selected AI provider (Claude, GPT, or Cursor).
The AI returns schema-validated JSON.
prbot posts the review as structured PR comments (including inline feedback).

No servers. No webhooks. Just a CLI.

Feature	Description
Multi-platform	Azure DevOps, GitHub, and Bitbucket Cloud
Your standards	Reviews against a custom `CodeStandard.md` file
Choice of AI	Claude (Anthropic), GPT (OpenAI), or Cursor Cloud Agents
Inline comments	Issues posted on the exact lines of code
Replace mode	Re-run reviews and replace old AI comments with fresh ones
Zero infrastructure	Just a CLI; no servers or webhooks to manage

Quick Start

# Clone and install
git clone https://github.com/mrlokeshagarwal/pr-bot.git
cd pr-bot
npm install
npm run build

# Make it global (optional)
npm link

Setup in 3 Steps

1. Choose your platform

Platform	Repo format	Auth
GitHub	`owner/repo`	Personal Access Token
Azure DevOps	`repo-name` or GUID	PAT
Bitbucket	`workspace/repo-slug`	App Password

GitHub:

prbot set platform github
prbot set repo owner/repo
prbot set github-token    # Prompts for your token

Azure DevOps:

prbot set platform ado
prbot set org https://dev.azure.com/YourOrg
prbot set project YourProject
prbot set repo YourRepo
prbot set pat            # Prompts for PAT

Bitbucket:

prbot set platform bitbucket
prbot set repo workspace/repo-slug
prbot set bitbucket-token

2. Add your coding standard

Create a CodeStandard.md with your team's guidelines. prbot sends this to the AI so reviews align with your rules.

prbot set standard C:\path\to\CodeStandard.md

3. Configure AI

# Claude (default)
prbot set provider claude
prbot set claude-key

# Or OpenAI
prbot set provider openai
prbot set openai-key
prbot set model gpt-4o

Run a Review

# Review PR #42
prbot review 42

# Dry run (see output without posting)
prbot review 42 --dry-run

# Replace old AI comments with a fresh review
prbot review 42 --replace

Tip: Use --dry-run on production PRs first to verify the output before posting comments.

What You Get

Each review includes:

Section	Description
Summary	High-level overview of the changes
Risk assessment	Potential issues or concerns
Questions	Clarifications the AI suggests
Issues	Specific findings with severity, file, line, and code snippets

All comments are prefixed with [AI Review] so you can easily identify and filter them.

Tech Stack

Technology	Purpose
TypeScript	Type-safe, modern JavaScript
Node.js 18+	Native `fetch`, no extra HTTP libs
Commander	CLI framework
Zod	Schema validation for AI responses
diff	Unified diff generation for Azure DevOps
