AISlop Guide: How to Catch AI-Generated Code Smells Before They Reach Production (2026)

Every team using AI coding agents is quietly accumulating the same debt. The code compiles. Tests pass. The pull request looks fine. And then, three months later, the codebase has a catch block that silently swallows production errors, a TypeScript file gutted by as any casts, and a TODO stub returning hardcoded data to real users.

This is AI slop — and it ships every day, across every team that has adopted Claude Code, Cursor, Copilot, or Codex.

AISlop is the quality gate that catches it before it merges.

TL;DR: AISlop is a free, open-source CLI that scans your codebase for the specific code patterns AI coding agents leave behind. One command: npx aislop@latest scan. Over 50 checks across 7 languages. Zero API calls. Works offline. It's the linter your AI-assisted workflow has been missing.


What Is AISlop? (And Why Everyone's Talking About It)

AISlop was built by developer Kenny Olawuwo and launched in June 2026 on Dev.to and Hacker News. The premise is simple: AI coding agents have a different failure profile than human developers, and existing linters weren't designed for it.

Your ESLint or Pylint setup catches style violations, unused variables, and syntax errors. What it does not catch is the pattern where an AI agent writes error handling that looks correct but silently swallows failures, or adds type casts that make the compiler quiet without making the code safe.

The tool has 50+ checks across Python, TypeScript, JavaScript, Go, Ruby, Rust, and Java — targeting the exact patterns that AI coding agents produce when they're optimizing for "make the prompt work" instead of "keep this codebase healthy."

In mid-2026, when Cursor, Claude Code, and Copilot have become standard tools in most development workflows, a tool specifically designed for their failure patterns isn't a nice-to-have. It's infrastructure.


Who Is AISlop For?

AISlop is for developers and engineering teams who use AI coding agents regularly and want to keep code quality high without slowing down. Specifically:

  • Solo developers using Claude Code or Cursor who want a quick sanity check before committing
  • Tech leads reviewing more AI-generated PRs than ever and wanting a first-pass filter
  • DevOps engineers looking to add an AI-specific quality gate to CI/CD pipelines
  • Freelancers and consultants who want to offer AI code quality auditing as a service
  • Open source maintainers receiving agent-assisted contributions from external contributors

If you're writing any code with AI assistance in 2026, AISlop belongs in your workflow.


Key Features of AISlop

50+ Language-Specific Checks

AISlop ships with over 50 checks across 7 languages, targeting patterns specific to AI output: swallowed exceptions, unsafe type casts, dead code and unreachable branches, TODO stubs in production paths, hardcoded environment values, narrative comments, and duplicated helpers. Each check is documented with the why — not just what it catches, but why AI agents produce it.

Zero API Calls, Fully Offline

AISlop runs entirely locally. No API key required. No telemetry. No internet connection needed. This matters for teams with strict data policies and for developers who want a fast pre-commit check that doesn't depend on an external service.

Auto-Fix for Mechanical Issues

Many of AISlop's findings have an auto-fix mode. Run aislop scan --fix and it will automatically resolve the mechanical issues — removing empty catch blocks, stripping narrative comments, converting hardcoded values to environment variable references.

CI/CD Integration Built In

AISlop ships with a dedicated aislop ci command designed for pipeline use. It diffs against a base branch, reports only new findings, exits non-zero on violations, and prints a clean summary that can be posted as a PR comment.

Claude Code Hook Support

Run aislop hook install --claude and AISlop becomes part of your Claude Code workflow automatically. Every session ends with a quality report. You catch the slop before it enters your review queue.


How to Get Started with AISlop in 5 Minutes

Getting AISlop running takes less than the time to read this section:

  1. Run a scan instantly with no install
npx aislop@latest scan
Enter fullscreen mode Exit fullscreen mode

npx pulls the latest version and scans your current directory. You'll see a scored report in seconds.

  1. Scan only changed files (recommended for daily use)
npx aislop@latest scan --changes
Enter fullscreen mode Exit fullscreen mode

Limits the scan to files modified since your last commit. Much faster. Ideal for pre-commit hygiene.

  1. Install as a project dev dependency
npm install --save-dev aislop
Enter fullscreen mode Exit fullscreen mode

Then add "lint:ai": "aislop scan --changes" to your package.json scripts.

  1. Add it to CI/CD
aislop ci --changes --base origin/main
Enter fullscreen mode Exit fullscreen mode

Drop this into your GitHub Actions or GitLab CI pipeline. PRs with AI slop get blocked automatically.

  1. Install a Claude Code hook
aislop hook install --claude
Enter fullscreen mode Exit fullscreen mode

AISlop runs automatically after every Claude Code session.


7 Best Use Cases for AISlop

1. Pre-Commit Gate on All AI-Assisted Work

Set aislop scan --changes as a pre-commit hook using Husky. Every developer using Cursor or Claude Code gets a quality report before code enters the review queue. The effect is behavioral: developers start fixing issues before committing rather than letting them accumulate.

2. CI/CD Merge Blocker

aislop ci --changes --base origin/main in your pipeline blocks PRs that contain swallowed exceptions, unsafe casts, or production TODO stubs. No more slop reviews eating code review time.

3. Codebase Debt Audit After Adopting AI Tools

Your team adopted Copilot three months ago. Run aislop scan on the full repo and get a scored baseline report. Use it to prioritize a cleanup sprint before the debt compounds.

4. Open Source Project Quality Control

Before merging agent-assisted contributions, run AISlop on the PR. Maintains quality standards without requiring every reviewer to maintain a mental model of AI failure patterns.

5. Code Quality Consulting Service

Run aislop scan on a client's repository, generate the scored report, and walk them through the findings. Charge $150-$500 per audit. The tool does the scanning; you provide the expertise.

6. Team Onboarding Documentation

Use the aislop report on your own codebase to build a "what not to accept in review" guide for new engineers. Real examples from your own code are more effective than abstract rules, and they're automatically generated.

7. Educational Developer Content

Record your screen running AISlop on a public GitHub repo. Walk through each finding, explain the pattern, and show the fix. High-signal developer content — the tool does the finding, you do the teaching.


5 Copy-Paste Prompts for AISlop

Use these with Claude Code, Cursor, or any AI coding agent after running an AISlop scan.

Prompt 1: Fix a Swallowed Exception

AISlop flagged this catch block in my code: [paste code]. It is swallowing the error and returning an empty array. Rewrite this function to handle the error properly. Log the error with context, surface it to the caller appropriately, and preserve the original stack trace. Show me the fixed version.

Prompt 2: Replace Narrative Comments

AISlop flagged these comments as narrative — they describe what the code does instead of why a decision was made: [paste code with comments]. Rewrite the comments to explain the intent, the constraint, or the non-obvious reason behind each decision. Remove any comment that just restates what the code is already doing.
Enter fullscreen mode Exit fullscreen mode

Prompt 3: Refactor Unsafe Type Casts

AISlop found unsafe casts in my TypeScript file: [paste code]. For each one, suggest the correct type. If the type cannot be determined statically, use unknown with a type guard instead. Show the refactored code with proper types throughout.
Enter fullscreen mode Exit fullscreen mode

Prompt 4: Generate a GitHub Actions Workflow

Write a GitHub Actions workflow file (YAML) that runs npx aislop ci --changes --base origin/main on every pull request targeting main. The job should fail if AISlop reports issues, post a summary comment to the PR with the findings, and pass cleanly when the code is clean.
Enter fullscreen mode Exit fullscreen mode

Prompt 5: Create a Team AISlop Config

Create an aislop.config.js for my team that sets severity thresholds (swallowed exceptions = error, narrative comments = warning, as any = error), excludes the /legacy directory from all checks, and adds a custom rule flagging any console.log left in production code. Write the full config file.
Enter fullscreen mode Exit fullscreen mode

AISlop vs. ESLint: Which Should You Use?

The right answer is both.

ESLint catches style violations, syntax errors, unused variables, and general code quality issues. It was designed for human-written code and is essential regardless of how the code was produced.

AISlop catches patterns that general linters don't model: the specific ways AI coding agents fail when optimizing for task completion rather than codebase health. The two tools are complementary — they don't overlap, they stack. Teams running both catch more issues than teams running either alone.

Absolutely. The install is npx aislop@latest scan with no configuration needed. The output explains each finding, making it a learning tool as well as a quality gate.


Final Verdict

AISlop solves a problem that wasn't possible to have three years ago. AI coding agents produce a specific, repeatable failure profile that existing linters weren't designed to catch. AISlop was built for exactly that gap.

If you're using Claude Code, Cursor, Copilot, or Codex in 2026 — and you almost certainly are — AISlop belongs in your workflow. The install takes 30 seconds. The first scan will find something. The CI integration takes under 10 minutes. And the impact compounds: every PR that doesn't merge AI slop is a PR that doesn't become technical debt six months from now.

The tool is free, open source, and offline. There's no reason not to try it today.
