dym-impeccable-detect-cli-scan

dym-impeccable-detect-cli-scan is a skill for Claude Code from Rheinmir/setup. It costs 52 tokens per session (2,232 once invoked), scanned A, original, MIT.

A command-line scanner for common design problems in frontend code and rendered web pages. It checks files, folders, or URLs and can return findings as JSON.

In plain words
What is it for?
Use it to scan HTML, frontend source folders, or web pages for design anti-patterns and feed the findings into automated checks.
Why use it?
It provides repeatable checks without an AI model or API key, so design issues can be found before review. Its exit code and machine-readable output also support pre-commit hooks and CI.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./node_modules/.bin/impeccable detect src/ 2> findings.txt # tách luồng đúng.

Good fit Use it to scan HTML, frontend source folders, or web pages for design anti-patterns and feed the findings into automated checks.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

dym-impeccable-detect-cli-scan 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 yesterday.

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.

Skill: dym-impeccable-detect-cli-scan — Quét anti-pattern bằng CLI

Vì sao dùng: chấm chất lượng design của code frontend một cách tất định — 61 luật, không LLM, không API key, chạy được trong pre-commit hoặc CI. Sinh ra cái gì: danh sách finding ra stderr (hoặc JSON ra stdout với --json), cộng một mã thoát để tự động hoá rẽ nhánh.


Chạy nhanh

npx impeccable detect src/                    # quét thư mục
npx impeccable detect index.html              # quét một file HTML
npx impeccable detect https://example.com     # quét URL (render bằng Puppeteer)
npx impeccable detect --json .                # JSON cho máy đọc
npx impeccable detect --no-config src/        # quét thô, bỏ mọi config/waiver của dự án

Dạng rút gọn cũng chạy: npx impeccable src/. cli/bin/cli.js:23-30 coi một tham số là target khi nó bắt đầu bằng -, là URL, chứa //\/., hoặc là đường dẫn có thật; ngược lại nó bị coi là lệnh gõ sai:

npx impeccable frobnicate
# Unknown command: "frobnicate"
# rc = 1

Output thật trên một file bẩn:

probe/index.html
  [gray-on-color] text #808080 on bg gradient(#667eea, #764ba2)
    → Gray text looks washed out on colored backgrounds. ...
  [low-contrast] 1.1:1 (need 4.5:1) — text #808080 on #667eea
    → Text does not meet WCAG AA contrast requirements ...
  [overused-font] Primary font: inter
    → Inter, Roboto, Fraunces, Geist, Plus Jakarta Sans, and Space Grotesk are used on so many sites ...
  [skipped-heading] <h1> "Hi" followed by <h4> "Skipped heading" (missing h2)
  [ai-color-palette] Purple/violet accent colors detected

7 anti-patterns found.

Mã thoát — đọc kỹ, đừng giả định 0/1

Từ cli/engine/cli/main.mjs:492-495:

const exitCode = hadOperationalFailure ? 1 : (primary.length > 0 ? 2 : 0);
rc Nghĩa
0 Quét xong, không có finding chính (advisory vẫn có thể được liệt kê)
1 Ít nhất một target không quét được — lỗi vận hành, ưu tiên hơn rc 2
2 Quét xong và có finding chính

What this file has done since we first saw it

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.
