What it does

Duplicate Description is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing a site's meta tag uniqueness, generating page-specific meta descriptions, or reviewing CMS templates that inject the same description globally.

Its SKILL.md is about 700 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).

It sits in Marketing & SEO, covering On-page SEO. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.

When your agent uses it

  • Auditing a sites meta tag uniqueness
  • Generating page-specific meta descriptions
  • Reviewing CMS templates that inject the same description globally

Example prompts

  • “/duplicate-description”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. List every page with a duplicate meta description.
  2. For each page, write a unique description that summarises that page's specific content (50–160 characters).
  3. In Next.js/React, pass a dynamic description prop through your SEO component instead of a static string.
  4. In WordPress/CMS, disable site-wide description fallback in your SEO plugin (Yoast, RankMath) and set per-post descriptions.

What it can do on your machine

Read from SKILL.md and the folder at commit e8d14d0. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    Links to these hosts (documentation or services it may open):

    • frontendchecklist.io

    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

Duplicate Description loads about 695 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 46 tokens; SKILL.md has 319 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~695
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.8k

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); files beside SKILL.md are not scanned.

Avoid duplicate meta descriptions

When multiple pages share the same meta description, Google ignores them and generates its own snippet, often pulling unrelated text. Unique descriptions improve click-through rates from search results and help users quickly understand what a page offers.

Quick Reference

  • Each page must have a unique <meta name="description"> — never reuse the same text across multiple pages
  • Google may auto-generate snippets when descriptions are duplicated or missing, often producing worse results
  • Target 50–160 characters; craft descriptions that describe the specific page, not the site

Check

Scan the HTML of every page for <meta name="description" content="...">. Identify any description value that appears on more than one URL. Flag pages using the same description as another page, and flag pages where the description matches the site tagline or homepage description.

Fix

  1. List every page with a duplicate meta description.
  2. For each page, write a unique description that summarises that page's specific content (50–160 characters).
  3. In Next.js/React, pass a dynamic description prop through your SEO component instead of a static string.
  4. In WordPress/CMS, disable site-wide description fallback in your SEO plugin (Yoast, RankMath) and set per-post descriptions. Example of a unique description per page:
  • Homepage: "Front-End Checklist helps developers build faster, more accessible, and better-ranked websites."
  • Blog post: "Learn how canonical tags prevent duplicate-content penalties and consolidate PageRank across URL variants."

Explain

Duplicate meta descriptions tell Google the pages are interchangeable, diluting search visibility. Each page competes in search for different queries, so the description must match the page's unique intent and content to earn a relevant snippet and a higher click-through rate.

Code Review

Check that no two <meta name="description"> tags in the rendered HTML across different routes share identical content values. Confirm the description is set dynamically per route in the framework's head management (e.g., Next.js metadata export, Nuxt useHead).

For full implementation details, code examples, and framework-specific guidance, see references/rule.md.
