We all recognize AI writing when we see it. As language models get used for everything, their specific tics are everywhere.
People call this **"AI slop"**. The grammar is fine, but the text is boring, repetitive, and lacks any real voice.

A site called [tropes.fyi](https://tropes.fyi/) tracks these patterns. It lists the exact words and structures that give AI away.
You'll see callouts for overused adverbs like _"deeply"_ and _"arguably,"_ the dreaded _"delve"_ family, and structural crutches like _"It's not X, it's Y."_

I wanted a way to automatically fix these issues in my own generated text.
So, I built a `deslopify` skill for [Gemini CLI](https://geminicli.com/).

## How I built it

Gemini CLI has a built-in [`skill-creator`](https://geminicli.com/docs/cli/creating-skills/) that handles the boilerplate.
I just asked the CLI to create a new skill, and it generated the folder structure and a `SKILL.md` file.
It took as reference the Markdown file shared by [tropes.fyi](https://tropes.fyi/) with all the typical elements of AI sloppiness.

The `SKILL.md` file tells the agent how to behave.
I wrote a short workflow instructing the agent to read the user's text, cross-reference it with the anti-patterns from [tropes.fyi](https://tropes.fyi/), and rewrite it.
The goal is just to make the text sound like a normal person wrote it.

Here's what the skill generated by Gemini CLI looks like:

The structure of the skill is just this `SKILL.md` file, and a `references/` directory containing the style guide:

```
deslopify/
├── SKILL.md
└── references/
      └── style_guide.md
```

I didn't even have to modify the generated `SKILL.md` as it did the job perfectly, and was clear out of the box.

## Trying it out

The code is up on GitHub: [glaforge/deslopify](https://github.com/glaforge/deslopify).

You can install it directly from the repo in Gemini CLI:

```bash
gemini skills install https://github.com/glaforge/deslopify
```

Then reload your interactive session:

```bash
/skills reload
```

> [!INFO] Information
> Because the skill format is just a directory with a `SKILL.md` file and some assets, you can actually use it in any AI agent that supports the standard.
> Be sure to check the syntax and command to install it in your favorite agent.
> And feel free to read more about [agent skills](https://agentskills.io/home) to understand their structure.

Once it's loaded, you can ask Gemini CLI (or your preferred agent tool) to clean up your text:

- `"Deslopify this article: [URL]"`
- `"Naturalize this draft: [paste text]"`
- `"Remove the AI slop from my README.md file."`

The agent will strip out the pompous phrasing and weird structural tics, leaving you with something far more readable.

> [!QUESTION] Is this text generated?
> If you were wondering, yes, I generated a good chunk of this blog post from my session in Gemini CLI when creating the `deslopify` skill!
> I went through each and every sentence and made some light edits or sometimes added a paragraph or extra clarification sentence.
> I also added all the screenshots, added missing links.
> But the skill worked, and for quickly sharing details about a little project like this, this skill came in handy to avoid the _blank page_ syndrome.
> Hopefully, you won't feel bored reading it!
