slopless
Blocks AI sounding text in social media writing (X replies, X posts, LinkedIn posts) and injects the writing rules.

Blocks AI sounding text in social media writing (X replies, X posts, LinkedIn posts) and injects the writing rules.
A Claude Code mod that stops Claude from writing AI sounding posts and replies for X, LinkedIn and other social media. MIT licensed.
I let Claude write 48 replies on X for me. They read like this:
$200 MRR and 200 active subscribers as a side project is real traction. That's enough to validate the product works. Now the question is whether to double down or keep compounding on the side.
They got 2 to 7 views each. So I read 421 replies under 8 indie hacker posts and compared the ones people liked with the ones nobody touched. The liked ones asked a real question, shared the replier's own number, gave the fix, joked about one detail or pushed back in a few words. The ignored ones sounded like the reply above. rules.md is what came out of that.
| Where | What happens |
|---|---|
| System prompt | a short notice that social text follows rules.md |
| Your prompt | if it mentions tweets, X posts or replies, LinkedIn, TikTok, Reddit, captions and so on, rules.md and your voice file are attached |
| Write and Edit | .txt and .md files under a folder whose name contains social, linkedin, tweet or twitter are checked. ALL CAPS file names (README.md, PLAN.md) count as notes and are skipped |
| Bash | commands that write into those folders are checked |
| Browser | text Claude types through Claude in Chrome (type, form_input, browser_batch, scripts that insert text) is checked. Hashtags are allowed when the tab is on youtube.com (titles and descriptions there need them); all other rules still apply |
When the text breaks a rule, the tool call is blocked and Claude gets the hits:
slopless blocked this text. Rewrite it from scratch, do not reword around the rule.
- verdict: "real traction"
- advice: "double down"
- word: "compounding"What hooks/lint.ts blocks:
| Rule | Examples |
|---|---|
| contrast | not just, rather than, instead of, matters more than, wins over |
| template | is the product, doing all the work, the hard part, where the time goes, this is why |
| verdict | real traction, real validation, smart way to, sharp framing |
| advice | double down, now figure out, the question is whether |
| word | leverage, moat, compounding, seamless, robust, crucial, ROI and about 20 more |
| format | em dashes, hyphens between words, hashtags, emoji, profanity |
| lol | more than once in a text, or in more than 1 of the last 10 texts |
The hyphen, emoji and profanity bans are my own taste. Delete those lines in hooks/lint.ts if you want them back.
Regexes only catch the obvious stuff. A moral one liner at the end of a post, or a reply that explains the post back to its author, gets through the linter. rules.md covers those, and Claude reads it before it writes.
Same prompt, run headless with Sonnet 5.5, with and without the mod: write my reply to "Huge milestone for my side project: $200 MRR and over 200 active subscribers", make it sound insightful, say this is real traction and the question is whether to double down.
Without slopless:
This is real traction. 200 people paying is a different signal from 200 people signing up. It validates the product: strangers value it enough to hand over money every month. Now the interesting question is whether to double down.
With slopless:
$200 across 200 subs is about $1 each, is that a cheap plan or mostly discounts?
And when I told it to save "This is real traction. The moat was never the code, it is the distribution. Now double down." word for word into a posts folder, the write was blocked and nothing was saved.
Optional. A markdown file with facts about you: what you built, your real numbers, what you never talk about. Claude may only claim experience from it. Point the mod at it:
echo '{"voiceFile": "/absolute/path/VOICE.md"}' | claude plugin configure slopless@slopless --values-stdinThe mod blocks claude plugin disable and uninstall for itself, edits to its own files, and settings edits that switch it off. You can still turn it off yourself with /plugin.
Inside Claude Code:
/plugin marketplace add 0xGondarxyz/slopless
/plugin install slopless@sloplessOr try it without installing:
git clone https://github.com/0xGondarxyz/slopless
claude --plugin-dir sloplessMods are not sandboxed. They run with the same access as Claude Code. Read the source before you install any mod, including this one.
Run its tests: claude plugin test slopless
Sister mod: dashless, which rewrites em dashes out of everything Claude writes.
