# meta-description

## What it does

The skill owns the rules for `<meta name="description">`. It reads root `contextus.md` when present and asks for page type, search intent, locale, verified page facts, current description, body coverage, and sibling-page descriptions before writing.

The Swap Test is the sharpest rule here: if a description can move to a sibling page unchanged, it is not specific enough. Length is a warning, not a hard gate. Google has no fixed limit and truncates snippets per device and context, so the skill flags descriptions that are too short to explain value or padded with filler.

It makes no promises about CTR, rankings, or traffic: a meta description is not a direct ranking control. Output is a recommended description, a non-binding length warning, a rationale, and a body-coverage flag when the page cannot substantiate the claim. For the sitewide metadata lifecycle with implementation and production validation, use page-metadata instead.

# 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.
