# Marcus Delgado, Senior Frontend Engineer / Tech Lead at Fieldline (63-person B2B SaaS) — read of Slop Cleaner, June 13 2026

> 9 years frontend, last 2 leading a team of 5. We ship React daily. Half our code starts as Claude output now and the other half wishes it did. I have a 7-year-old who plays travel soccer and I'm losing Saturday mornings to driving her to Elk Grove. I listen to Syntax FM on the drive back.

## How I got here

Googled "eslint rules for AI generated react code" after spending 45 minutes in a PR review correcting useEffect dependency arrays that Claude left incomplete. Hit a dev.to article that mentioned this in a comment. Comment was vague but said "Slop Cleaner handles that exact problem." Clicked. That's it.

## What I clicked first

The problem list in the hero pulled me in immediately. "Missing dependency arrays in useEffect and useMemo" is literally what I was just looking at in a PR. "Prop drilling instead of context or state management" is the second most common thing I flag. That list reads like someone actually reviewed AI-generated React output and wrote it down, not like someone reverse-engineered the problem from a pitch deck.

"Paste code. Get clean, production-ready components back." is where I slowed down. That's a big claim. Clean. Production-ready. Those words do a lot of work.

## Where I paused

The moment I hit the pricing section and realized I was not on a tool page. I was on a BUSINESS IDEA page. The tiers are: Browse Free, Unlock the dossier for $5, Adopt the build for $99-$199. What they're selling is a strategy package and brand starter kit for someone to go BUILD this tool. They say it plainly: "we don't have live customers on this idea yet. We shipped the strategy package; you ship the customer conversations."

I sat with that for a bit. I came here because I have a real problem today and I wanted something to install. Instead I found someone selling the map to the gold mine, not the gold.

That is not dishonest -- they say it clearly. But it broke something in my read. Everything above the pricing felt like marketing for a live product, and then you scroll and the ground disappears.

## What I distrusted

"AST-Powered Parsing" in the feature list. That's a real technique -- but it's also exactly what ESLint already does. We have eslint-plugin-react-hooks. We have eslint-plugin-jsx-a11y. These do most of what's described here. The "Team Rules Engine" feature is literally just custom ESLint rules. So either this is a thin wrapper around ESLint that makes it easier to configure for AI output patterns (useful!) or it's describing standard ESLint functionality with nicer copy (not useful).

I have no way to tell which from this page because there's nothing to try. The "Try Free (5 Components)" CTA links to... I don't know where. There's no screenshot, no demo video, no example input/output. If you've built an AST analyzer that catches something eslint-plugin-react-hooks misses, show me one example. One specific diff. Before and after.

Also the Fermi math sitting on the same page as the product pitch is a strange experience. "$-8,927 Year-1 take-home" and "1 in 8 meaningful success odds" are honest numbers, and I respect the honesty, but they also tell me the people selling this do not think this is a great business. That transparency is admirable and also a little discouraging.

## What would convince me

Show me one component that went in and one component that came out, side by side. Specifically one where the before is plausible Claude output (I can tell the difference) and the after is what a senior engineer would actually merge. Not a toy example with a missing key prop. A real one with a stale closure in a useEffect and a missing memo that causes a cascading re-render.

If this is NOT just an ESLint config wrapper, I need to know what it catches that eslint-plugin-react-hooks misses. That delta is the whole product.

And if someone has actually built this and is using it on a real codebase, one person saying "we went from X hours of AI code review per week to Y" would do more than everything else on the page combined.

## What I'd ask in an email reply

1. What does this catch that running eslint-plugin-react-hooks plus eslint-plugin-jsx-a11y wouldn't already catch? Specific example.
2. Is there a working tool right now or am I buying a plan to build one? If the former, where's the link?
3. The Team Rules Engine -- does that mean I write custom rules in JavaScript like a normal ESLint plugin, or does it mean something else?

## Verdict: on-the-fence

If this is a live tool with a real demo, I would 100% spend 20 minutes trying it. The problem list is exactly right and the framing is sharp. But right now I cannot tell whether there's a product here or just a well-written idea, and that uncertainty is doing a lot of damage to my trust. The honest disclosure is admirable. The missing demo is fatal.
