Why It Matters

Engineering teams lose hours every week waiting on code reviews, and critical defects slip through when reviewers are overloaded. An AI PR reviewer gives every pull request the same rigorous, consistent analysis — instantly, at any time of day — so engineers can ship confidently and focus on building.

Platform Capabilities

Architect provides every capability you need to build a production-grade AI PR reviewer — from code diff parsing to multi-tool action execution.

Code Diff Analysis
The agent ingests the full diff of a pull request — additions, deletions, and context lines — and runs LLM-powered analysis to detect logic errors, anti-patterns, and security risks.
Security Vulnerability Detection
Automatically flags OWASP-class vulnerabilities, hardcoded credentials, unsafe dependencies, and injection risks before they reach the main branch.
Style and Standards Enforcement
Enforces your team's coding conventions, naming patterns, and documentation requirements — configurable per repository and programming language.
Inline Comment Generation
Posts actionable, line-level comments directly on the pull request in GitHub — not just a summary, but precise feedback anchored to the exact lines that need attention.
Configurable Review Policies
Define custom rulesets for different repos, branches, or teams. Control severity thresholds, auto-approval rules, and which findings block a merge.
Multi-Channel Notifications
Sends structured review summaries to Slack channels, creates Jira tickets for critical findings, and pings the right engineers based on code ownership rules.

How It Works

From pull request open to reviewed in seconds — four automated steps, zero human bottlenecks.

Step 01
PR Webhook Fires
GitHub sends a webhook event when a PR is opened, updated, or marked ready for review.
Step 02
Agent Fetches Diff
Architect pulls the full code diff, file list, PR description, and linked issue context via GitHub API.
Step 03
LLM Reviews Code
The AI model analyzes for bugs, security issues, style violations, and missing tests against your configured policy rules.
Step 04
Feedback Posted
Inline comments and a review summary are posted to GitHub. Slack and Jira are updated based on severity findings.

Before vs After Architect

See exactly what changes when you automate your pull request review process with an Architect agent.

Without Architect
  • PRs wait 2-3 days for a human reviewer to become available
  • Senior engineers spend 30-40% of their time on manual code reviews
  • Security issues and logic bugs slip through during peak delivery periods
  • Review quality is inconsistent — depends on the reviewer and their workload
With Architect
  • Every PR receives a first review within seconds of opening — day or night
  • Senior engineers focus on architecture decisions, not mechanical review tasks
  • Security vulnerabilities and critical bugs are caught before they reach production
  • Consistent, policy-driven review quality across every PR in every repository

Sample Agent Prompt

This is the system prompt you configure inside Architect to define your AI GitHub PR Reviewer agent's behavior, scope, and output format.

You are an expert code reviewer integrated into a GitHub pull request workflow.
When a pull request is opened or updated, you will:
1. Retrieve the full code diff and file list from the GitHub API.
2. Analyze each changed file for: logic errors, security vulnerabilities (OWASP Top 10),
   style violations against the project's .eslintrc / .pylintrc, and missing test coverage.
3. Post inline review comments on specific lines using the GitHub Review API.
4. Output a structured review summary with: severity (critical / warning / suggestion),
   file path, line number, and a concise actionable description per finding.
5. If any CRITICAL findings exist, submit a "REQUEST_CHANGES" review decision.
6. If no issues are found, submit an "APPROVE" decision with a summary comment.
7. Notify the #engineering Slack channel with a review link and finding count.
Always be specific, cite line numbers, and suggest a fix — never just flag without guidance.

Frequently Asked Questions

What is an AI GitHub PR Reviewer agent?
An AI GitHub PR Reviewer agent automatically analyzes pull requests for code quality, security vulnerabilities, style violations, and logical errors — posting structured review comments directly on the PR without human intervention.
How long does it take to build a PR reviewer agent with Architect?
With Architect by Lyzr, you can configure and deploy a fully functional AI GitHub PR Reviewer agent in under 10 minutes using the no-code visual builder. No infrastructure setup required.
Which repositories and programming languages does the agent support?
The agent connects to any GitHub repository via webhook triggers and can review code in any language, including Python, TypeScript, Go, Java, Rust, and more. Language-specific rules can be configured per repository.
