What it does

Unslop UI is an agent skill from JCarterJohnson/vibecoded-design-tells. Strips the cues that make a website read as AI-generated and forces a deliberate, project-specific design choice instead of the model's default. It does not impose a look or hand you taste. It removes tells (default shadcn/Tailwind, AI-purple gradients, gradient heading text, unprompted neon glow, emoji-as-icons, the centered hero plus three feature cards) AND the newer cream-plus-serif-plus-sage "tasteful default" that trading one default for another creates. Grounded in a 47-subreddit, 3.2M-post Reddit analysis…

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `README.md`, `references/choosing-a-look.md` and `references/tells.md`).

It sits in Frontend & Design, covering Design systems, CSS and styling and Landing pages. It works with Reddit, shadcn/ui and Tailwind CSS. The repository describes itself as: Reddit-mined data ranking the visual tells of vibe-coded (AI-built) sites: 3.2M posts scanned across 47 subreddits, with scripts, raw data, and charts.

When your agent uses it

  • Auditing any website
  • Front-end component
  • Especially when the user wants a site to look custom
  • Human rather than AI-generated

Example prompts

  • “tasteful default”
  • “Use the unslop-ui skill to strip the cues that make a website read as AI-generated and forces a deliberate, project-specific design choice instead…”
  • “/unslop-ui”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit f7c4aef. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unslop UI loads about 1.9k tokens when it runs, and up to ~7.4k if it reads all its reference files. Until then it costs about 228 tokens; SKILL.md has 1,030 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~228
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,030 words (~1,874 tokens).

“Read this first, because the most common misunderstanding sinks the whole thing.”
