  I’m eager to test this out. I have agent instructions to try to limit the worst of this already, but patterns still sneak through. I have a review agent run after every single edit looking for all of the following if you need more ideas for checks:- DRY principle violations, multiple definitions of the same helpers or utilities.- Changes that deviate from existing patterns and architecture already in the code, especially in nearby and related code- Comments that add no context or simply restate the field name.- Naming violations (enterprise factoryfactoryabstraction stuff, excessively long names, overly technical names, banned words like “seam”, “durable”, and no-value-qualifiers like “SaveGame” -> “Save”).- Tests that check implementations instead of correct business behavior.- Overly backwards-compatible unless asked for (this one is incredibly hard to keep under control, as AI loves to guard everything even if the previous code was never deployed and thus there is no contract break)- Un-necessary guard code (this is hard to control, most common case is the AI not relying on the serializer error handler and instead adding guards that the library already handles)- Changing public API contracts without express permission to do so (depends on the code, eg a library JAR or versioned REST service)- Meta references to previous code versions, to tasks or todos, or to instructions and other non-code context (e.g you tell the AI the adder should ignore negative numbers and that meta fact enters the comments or code)I usually hand review all changes myself but it’s incredibly tedious so I try to first pass with the review agent until it comes back clean. I hate wasting tokens on it though.

  Apparently I need to check in with a Doctor because code written by myself is seen as AI, and the lazy AI bits aren't. More Human than Human?

  A linter with rules for AI-specific weirdness is absolutely a great idea, thank you! Are there any plans to support other languages besides javascript?

  I was about to write what advantage it has over linters but then saw the built on section. Good work. We use megalinter with our flavour of go and vite rules, plus extensive e2e testing after each agent run. Quality of the spec driven agentic PRs are significantly better than the baseline. Megalinter is quite resource heavy and slow, so will definitely check this out

  I don’t see if this is one of the covered cases, but one of the more common and nefarious patterns I run into is what you might call "sweeping exceptions under the rug." I think the agent’s motivation to get things running encourages these antipatterns of designing routines that are fault tolerant in a sort of maladaptive way: e.g. catching an error, logging a warning that something didn’t work, and continuing, but with now potentially missing/broken state.This has bitten me a couple of times, and it’s surprisingly annoying to nudge agents into good/resilient patterns or identify situations that should fail loudly, at least in my experience. The retry mechanisms they come up with on their own are often pretty terrible as well.I’ll note, though, that I have seen this from human engineers plenty of times, and at least the AI usually adds some logs rather than just totally silently absorbing an exception!

  This is a great idea. Even if you're one of those developers squarely focused on getting the final result working, code quality still matters (to people and LLMs).Everyone should be doing regular code reviews and this helps a lot.

  For anyone who wants something like this for Elixir, there is an open source hex package: https://hex.pm/packages/ex_slop

  I think a lot of the telltale signs of AI can be found in the comments. Besides the slop writing style, I've found AI comments to 1. be overly verbose, 2. unnecessarily describe before/after code state (# This function used to do foo, but now it does bar), and 3. reference its own internal "plan" (# This function is part of Stage 3 of the implementation of Use Case X from the requirements doc) WTF is Stage 3? - says code reader 2 years from now. Although I bet you can probably prompt these behaviors away.

  Gave it a try but there were a lot of false positives. SQLModel's exec method for example gets flagged every time thinking it's python's exec() function.

  > I’ve been building aislop.This made me chuckle.Cool tool, the dead code checks can be very helpful. I’ve seen Claude leave unused functions when iterating which always frustrates me.

  Ran it in my codebase, detected some good stuff, was able to pass the issues to my agent so they can be validated and fixed. Good job!I'd love for it to have flags for Pi and Crush too :)

  Can you explain the benefits of running this over rector / eslint? (and to certain degree phpstan / deptrac)

  I tried it on my codebase. There's a lot of overlap with tools like Oxlint / ESLint, I'm not sure that's too valuable vs. a more focused tool that actually focuses solely on 'slop' signals. These lint rules tend to get very opinionated which is why those tools expose so many configuration options.One real bug tho:> [ERROR] Imports "mdast" but it's not declared in package.jsonA type-only import like `import type { Blockquote, RootContent } from 'mdast';` is actually acceptable if `"@types/mdast": "^4.0.4"` is included in the package.json.

  I tried it but see a lot of false positives.One funny thing I see it doing is deleting seemingly random comments lines, for example if a file has a comment that spans multiple lines but doesn’t use a multi line comment syntax. It just chooses one at random transforming the once useful comment into slop.

  Apparently https://github.com/scanaislop/aislop with AGENTS.md is not AI slop, but projects of mine last modified before 2016 all contain critical AI slop. So very accurate.

  awesome work, someone is caring about using less token :clap:

  Related, we made "Antislop", a framework for removing repetitive phraseology from LLMs: https://arxiv.org/abs/2510.15061

  The intent is good, but frankly, credibility is lost by using "slop" words imo, OP you might seriously want to re-evaluate who is the target market, probably users that leverage high automation 24/7, startups and so-on, they don't want to incorporate products that talks about the modern way (and somehow only way to compete) of development as "slop" imo because soon enough, it's not true anymore (it's already not true with the right tooling).

  I don't think this approach is wise.Concentrate on code quality, and whether it does what it needs to do. Not whether it was written by AI or not.
