## What it does

This skill evaluates code readability and taste across 24 rules grouped into 6 categories: comments, naming, over-engineering, defensive overdose, test quality, and style markers. Standard linters catch syntax and quantitative debt, but AI-generated code often passes CI while remaining bloated. The rules flag single-method classes, unnecessary null assertions, and comments that restate the next line.

The workflow detects the project stack via `composer.json` or `package.json`. The agent examines changed files or whole repos, sorting issues into a Slop Ledger table with verdicts from CLEAN to CRITICAL. Findings highlight concrete problems like catch blocks masking errors, redundant types on literals, or tests without actual assertions.

Because the rule catalog targets PHP and TypeScript ecosystems specifically, running it on Python, Go, or Rust repositories will not yield meaningful checks.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill code-slop -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/code-slop/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/code-slop/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill code-slop -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/code-slop/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill code-slop -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/code-slop/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install AsyrafHussin/agent-skills code-slop
```

2. **Manually: put the files in place**
- File: `.github/skills/code-slop/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill code-slop -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/AsyrafHussin/agent-skills --path skills/code-slop
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/code-slop/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill code-slop -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/AsyrafHussin/agent-skills/tree/HEAD/skills/code-slop/SKILL.md

## When to use it
- spot AI-generated code patterns in pull requests
- clean up narrating comments and empty docblocks
- catch premature single-implementation interfaces
- identify mock-heavy tests lacking behavioral assertions

## Example prompts
- review for AI slop across recent changes
- audit code-quality taste and find AI patterns in this PR
- check if the changed files feel human and generate a Slop Ledger

# Code Slop Detection

Taste-level review of code for AI-generated patterns. Contains 24 rules across 6 categories covering comments, naming, over-engineering, defensive overdose, test slop, and style fingerprints. Where [`technical-debt`](../technical-debt) measures *quantitative* code debt (complexity, duplication, CVEs), this skill measures the *qualitative* failure mode: code that passes every metric but reads like a tutorial blog post, not like a human wrote it.

## Metadata

- **Version:** 1.0.0
- **Scope:** PHP / Laravel + TypeScript / React (Node)
- **Rule Count:** 24 rules across 6 categories
- **License:** MIT

## Why this skill exists

Industry data on AI-assisted code (GitClear 2025, cURL bug-bounty shutdown 2025, arXiv 2510.03029):

- **Refactoring collapsed** from 25% to <10% of changes
- **Copy-paste surged** 8.3% → 12.3%; code duplication rose ~8x
- **Code-smell rates +42–85%** over human baselines
- **82% of AI PRs** use generic catch blocks that don't distinguish error types
- **76% miss timeouts** on external calls

None of this fails a typical CI lint. It just makes the codebase slowly unmaintainable. This skill is the lens for catching it before it ships.

The core insight: **reading cost > writing cost now**. The cost of writing code collapsed; the cost of reading it didn't. Code you can't quickly understand is slop, even if it works.

## How to Audit

When the user asks "review for AI slop", "audit code-quality taste", or "find AI patterns" — run through this skill's rules as a checklist against the changed files (PR diff) or full repo.

### Audit Step 1: Determine Scope

- If a PR diff is provided: audit only files changed in the diff
- If files are named: audit those
- If no scope: audit the whole repo, prioritized by recently-touched files (most likely AI output)

### Audit Step 2: Detect Stack

| Signal | Stack |
|--------|-------|
| `composer.json` + `artisan` | PHP / Laravel |
| `package.json` (with TypeScript/React deps) | Node / TypeScript / React |
| Both present | Laravel + Inertia + React |

### Audit Step 3: Run the Slop Checklist

For each item below, output:
- **CLEAN** — pattern not present (brief confirmation)
- **SUSPICIOUS** — present in small amounts; flag and discuss
- **INFLATED** — present extensively; verbose-but-functional; remediation recommended
```
