How to Use ESLint with Zowl

Every line of agent-generated code passes your lint rules before it hits a PR.

What is ESLint?

ESLint enforces code quality and consistency. Zowl runs ESLint as a pipeline verification step after agents generate code. If linting fails, Zowl feeds the errors back to the agent for automatic fixes — so every PR ships clean code.

How Zowl Helps

Without Zowl, you'd review agent output, run ESLint manually, then ask the agent to fix issues. Zowl automates this loop: generate code, lint, fix, lint again — until the code passes. Zero lint violations reach your PR.

Setup Guide

Configure ESLint in Your Project

Ensure ESLint is set up with your preferred rules. Zowl runs your existing ESLint configuration.

Add Lint Step to Pipeline

Add a verification node that runs npx eslint after agent code generation.

Enable Auto-Fix Loop

Configure Zowl to feed lint errors back to the agent for automatic fixing, with a retry limit.

Set Lint as Gate

Mark the lint step as required — PRs only get created if all lint rules pass.

Capabilities

Lint-Fix Loop

Agent writes code → ESLint catches violations → agent fixes them → repeat until clean.

Custom Rules

Your ESLint config is used as-is. Custom rules, plugins, and extends all work.

Auto-Fixable Rules

Zowl can run eslint --fix before involving the agent, saving tokens on simple formatting issues.

Per-File Reporting

Lint results are captured per file, so you can see exactly which agent-generated files had issues.

Frequently Asked Questions

Never. Zowl runs your existing ESLint setup exactly as configured. No config changes are made.

Yes. Add Prettier as a separate pipeline step or use the eslint-plugin-prettier integration.

After the configured retry limit, Zowl flags the issue in the PR description for human review instead of blocking the entire pipeline.
