slopguard

A filter for AI coding agents. Stops generic UI, filler copy, over-engineered code, and dishonest claims (invented APIs, “tests pass” without a run). DE and EN.

Not a style guide. It rejects slop; it does not pick your colors, fonts, or brand. Direction stays yours.

See the difference

Same brief, before and after the filter. These are the patterns the skill is built to catch.

Chat

Before	After
Sure! I'd be happy to help. Great question! Here's a comprehensive overview of how we can leverage a robust solution to seamlessly optimize your workflow…	The login fails because the token is cleared before refresh. Fix is in `auth.ts` line 42.
I hope this helps! Let me know if you'd like me to also add tests, docs, and a refactor.	Changed `auth.ts`. Tests not run.
Importantly, it is worth noting that…	(deleted, say the fact)

Commit message

Before	After
`update code`	`Reject empty catch in invoice fetch so payment errors surface`
`improve UX`	`Show invoice due date in the list row`
`implement comprehensive solution`	`Add DATEV CSV export on the payroll page`
`This commit aims to unlock…`	(rewrite: name the reason, no hype)

Error handling

Before	After
`catch (e) { return []; }`	Rethrow or pass to the existing error UI
`catch (e) { console.log(e); }`	Log with the project logger and surface failure
Empty `catch {}`	Not allowed: fix or fail visibly

  how -->|"rethrow or error UI"| pass["PASS"]

React

Before	After
`useEffect` that only copies `items` → `filtered`	Filter in render: `items.filter(...)`
`key={index}` on a sortable list	`key={item.id}`
New `utils/capitalize.ts` for one call	Inline or use existing string handling
`"use client"` on the whole page for one hook	`"use client"` only on that component
`UserServiceFactory` + interface for one caller	`getUser(id)` with the existing client

Hero / marketing copy

Before	After
Empower your workflow with seamless next-gen intelligence. Build faster. Scale smarter.	Export payroll as DATEV CSV in one click.
Trusted by teams at… · 99.9% Uptime · +127% Growth	(remove fake pills unless the user supplied real numbers)
Für Teams, die mehr wollen. Einfach. Schnell. Sicher.	Offene Rechnungen. Ein Klick zur Freigabe.

German prose

Before	After
Nicht nur schnell, sondern auch nachhaltig. Die Lösung ermöglicht es Teams, Mehrwert zu schaffen.	Der Export braucht unter zwei Sekunden. Die Liste zeigt offene Rechnungen und wer freigeben muss.
Im Hinblick auf die Herausforderungen und Chancen…	Beim Login scheitert der Refresh, weil…
Gerne! Gute Frage!	(start with the answer)

Structure tells (any language)

Before	After
Exactly three bullets every time	2, 4, or 5, whatever fits
Em dash in every paragraph	At most one per paragraph
Term: explanation · Term: explanation	Prose or a real table
Challenges / Outlook / Conclusion that restate praise	Cut or write a concrete next step
