slop-catalog

slop-catalog is a skill for Claude Code from alphabravo-oss/guild. It costs 121 tokens per session (3,784 once invoked), scanned A, original, MIT.

A reference catalogue of visual patterns that can make a user interface look automatically generated with Tailwind, a CSS utility framework. Each entry explains how to detect the pattern, when it is appropriate, and how to improve it.

In plain words
What is it for?
Reviewing interfaces for repetitive or unmotivated visual choices, detecting likely AI-generated design habits, and guiding fixes while accounting for legitimate exceptions.
Why use it?
It helps distinguish an intentionally designed interface from one that applies the same defaults everywhere. It also discourages flagging patterns that have a clear product or brand reason.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

slop-catalog scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.

damu — the AI-slop catalog

This is the reference both damu modes read from. Prevent renders the Fix lines into a prohibition ruleset. Remediate runs each entry as a detection lens, using Detect for the fact-signal and Legit when as the hard exclusions a lens must not flag.

The one rule that governs all the others

Every tell below is sometimes correct. A fintech dashboard is mostly cards. A children's app should be rounded and emoji-rich. A brand site may earn a parallax hero. The slop isn't the pattern — it's the pattern applied by default, without a reason, to everything. A finding is only real when the choice looks unmotivated and uniform. When in doubt, rate it LOW confidence rather than HIGH — surface it, but don't treat a plausibly-intentional choice as a confident finding. Flagging a justified choice as if it were obvious slop is itself a kind of slop.

A second governing read: soul. Slop is what you get when every decision defaulted. The opposite isn't "more design" — it's evidence that a human made a choice here and not somewhere else: one deliberate accent, asymmetry that means something, type that has a job, whitespace that breathes unevenly. Absence of any such choice across a whole page is the strongest tell of all.


SLOP-01 — Font chaos

  • The tell: 4–5 competing typefaces, often a display serif + a geometric sans + a mono + whatever the component library shipped, with no hierarchy logic. Looks amateur because nothing is in charge.
  • Why it reads AI: models stitch type from many sources and never cull. A human picks one or two and commits.
  • Fix: one or two families, max. A type system (one display + one text, or a single superfamily with weights). Hierarchy by size/weight/spacing, not by swapping fonts.
  • Detect: count distinct rendered font-family stacks across text nodes. >3 non-icon families ⇒ flag.
  • Legit when: an intentional editorial pairing (display + body + a deliberate mono for code/data) — 3 families with a clear job each is a system, not chaos.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
