What it does

Meta Description is an agent skill from kostja94/marketing-skills. When the user wants to write, audit, or optimize a meta description, SEO description, SERP snippet candidate, duplicate description, description length, or description rewrite issue. For a sitewide metadata lifecycle including implementation and production validation, use page-metadata.

Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering On-page SEO. The repository describes itself as: Agent Skills for Marketing — SEO, Social, Influencer & More. 160+ open-source skills for SEO, content, 40+ page types, paid ads, channels, and strategies. Add project context… The licence is MIT.

When your agent uses it

  • Optimize a meta description
  • SEO description
  • SERP snippet candidate
  • Duplicate description

Example prompts

  • “/meta-description”

What it can do on your machine

Read from SKILL.md and the folder at commit 8dd89c5. 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):

    • developers.google.com

    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

Meta Description loads about 670 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 310 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~670

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.

SEO On-Page: Meta Description

Owns writing and review rules for <meta name="description">. It is a candidate source for search snippets, not a guarantee of the text Google will display.

Inputs

Read root contextus.md when present. Confirm page type, primary search intent, locale, verified page-specific facts, current description, body coverage, sibling-page descriptions, and the intended next action when one exists.

Rules

  • Write an accurate, useful summary or pitch for the specific page.
  • Lead with information that distinguishes this page from sibling pages.
  • Use query-relevant language naturally, without a keyword list.
  • Length is a warning, not a hard gate. Google has no fixed meta-description length limit and truncates snippets as needed for the device and result context.
  • A description may exceed traditional character guidance when it remains concise and useful. Flag descriptions too short to explain value or too long because of filler, repetition, or boilerplate.
  • Use a CTA only when it suits the page task. Do not force marketing CTAs into legal, documentation, status, or informational pages.
  • Include price, author, date, availability, or compatibility only when present and current on the page.
  • Apply the Swap Test: if a description can move unchanged to a sibling page, it is not specific enough.
  • Localize from the target market's query language and intent; do not translate and truncate.
  • Google primarily creates snippets from page content and may show different text for different queries. Ensure the H2/body can substantiate the description's promise.
  • Do not claim a fixed CTR, ranking, or traffic increase. A meta description is not a direct ranking control.

Output

  • Recommended description and a non-binding length warning when useful.
  • Brief rationale tied to intent and page-specific facts.
  • Body-coverage warning if the page cannot substantiate the proposed description.
  • Sibling duplication or cannibalization warning when applicable; do not restructure pages.

Primary reference

  • page-metadata, title-tag, heading-structure
  • localization-strategy, translation, google-search-console
