Overview
An agentic QA engine that finds bugs, writes tests, reviews code, and opens pull requests with fixes.
The Paragon Agent is an agentic QA engine that clones your repository, analyzes your code for issues, writes tests, and opens pull requests with fixes. Use it from the dashboard, trigger it from GitHub comments and Slack, or automate it on schedules and events.
What It Can Do
- Find and fix bugs — Point it at an issue, error, or flaky test and it investigates and patches
- Write and improve tests — Generate unit tests, integration tests, and increase coverage across your codebase
- Review code quality — Catch security vulnerabilities, performance issues, and regressions before they ship
- Validate changes — Run builds, execute test suites, and verify nothing breaks
How It Works
- Select a repository — Choose a connected GitHub repository and branch
- Describe the task — Tell the agent what you want reviewed, tested, or fixed
- Agent executes — The agent clones your repo, analyzes the code, runs tests, and makes changes
- Review the PR — Review the diff in the dashboard or on the generated pull request
Session Modes
Paragon offers two session modes depending on task complexity:
| Mode | Best For | Duration | How It Works |
|---|---|---|---|
| Standard | Quick bug fixes, test generation, code review | Minutes | Single agent processes your prompt directly |
| Grind | Comprehensive test coverage, large-scale refactors, multi-file fixes | Hours | Plans first, then delegates to parallel workers |
Models
Choose a model tier when creating a session:
| Model | Speed | Best For |
|---|---|---|
| Max | Slowest | Complex debugging, nuanced code review, architecture-level issues |
| Mid | Balanced | Most tasks — good balance of quality and speed |
| Fast | Fastest | Simple fixes, test generation, straightforward patches |
