# Rspress Description Generator > Generate and maintain description frontmatter for Rspress documentation files (.md/.mdx). Use when a user wants to add SEO descriptions, improve search engine snippets, generate llms.txt metadata, prepare docs for AI summarization, or batch-update frontmatter across an Rspress doc site. Also use when adding new documentation pages to an Rspress project — every new doc file needs a description. - Skill: `dahlia/rspress-description-generator` (Agent Skill) - Install (CLI): `npx skillmds@latest add dahlia/rspress-description-generator` - Raw SKILL.md: https://api.skillmd.com/api/skills/dahlia/rspress-description-generator/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Marketing & Growth - Author: dahlia (https://skillmd.com/u/dahlia) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/dahlia/rspress-description-generator --- Rspress Description Generator ============================= The `description` field in Rspress frontmatter generates `` tags, which are used for search engine snippets, social media previews, and AI-oriented formats like llms.txt. Step 1 — Locate the docs root ----------------------------- 1. Find the Rspress config file. Search for `rspress.config.ts`, `.js`, `.mjs`, or `.cjs`. It may be at the project root or inside a subdirectory like `website/`. 2. Read the config and extract the `root` option. - The value might be a plain string (`root: 'docs'`) or a JS expression (`root: path.join(__dirname, 'docs')`). In either case, determine the resolved directory path. - If `root` is set, resolve it relative to the config file's directory. - If `root` is not set, default to `docs` relative to the config file's directory. 3. Confirm the directory exists. If neither `docs` nor the configured root exists, check for `doc` as a fallback. Step 2 — Detect i18n structure ------------------------------ Rspress i18n projects place language subdirectories (e.g., `en/`, `zh/`) directly under the docs root: ~~~~ docs/ ├── en/ │ ├── guide/ │ └── index.md └── zh/ ├── guide/ └── index.md ~~~~ Check if the docs root contains language subdirectories (two-letter codes like `en`, `zh`, `ja`, `ko`, etc.). If so, process each language directory separately — the description language should match the content language. If there are no language subdirectories, treat the entire docs root as a single-language site. Step 3 — Scan and process files ------------------------------- Glob for `**/*.md` and `**/*.mdx` under the docs root. Exclude: - `node_modules`, build output (`doc_build`, `.rspress`, `dist`) - `_meta.json` / `_nav.json` (sidebar/nav config files, not doc pages) - `**/shared/**` directories (reusable snippets included via `@import`, not standalone pages) For each file: 1. **Read the file.** 2. **Check for existing `description` in frontmatter.** If it exists and is non-empty, skip. 3. **Check `pageType` in frontmatter.** For `home` pages, derive the description from the `hero.text` / `hero.tagline` fields or the features list, not from body content. 4. **Generate a description** following the writing guidelines below. 5. **Insert `description` into frontmatter:** - If the file has frontmatter with a `title` field, insert `description` on the line after `title`. - If the file has frontmatter without `title`, insert `description` as the first field. - If the file has no frontmatter block, add one: ~~~~ yaml --- description: Your generated description here --- ~~~~ ### YAML formatting Most descriptions can be bare YAML strings: ~~~~ yaml description: Step-by-step guide to setting up your first Rspress site ~~~~ If the description contains colons, quotes, or other special YAML characters, wrap in double quotes: ~~~~ yaml description: 'API reference for Rspress configuration: plugins, themes, and build options' ~~~~ Step 4 — Batch processing ------------------------- For sites with many files, use parallel agent calls to process independent files simultaneously. Group by directory (e.g., all files in `guide/`, then all in `api/`) to maintain focus and consistency within each section. After processing all files, do a quick scan to ensure no files were missed — re-glob and check for any remaining files without `description`. Description Writing Guidelines ------------------------------ The description serves three audiences: search engines (Google snippet), AI systems (llms.txt, summarization), and humans (scanning search results). A good description helps all three. ### Rules - **Length**: 50–160 characters. Under 50 is too vague for search engines; over 160 gets truncated in snippets. - **Language**: Match the document content. Chinese docs get Chinese descriptions, English docs get English descriptions. - **Be direct**: State what the page covers. Avoid starting with “This document”, “This page”, “Learn about” — jump straight to the substance. - **Be specific**: Mention concrete technologies, APIs, or concepts the page covers. “Configure Rspress plugins for search, analytics, and internationalization” beats “How to use plugins.” - **No markdown**: Plain text only, no formatting syntax. ### Examples **Good:** | Content | Description | | -------------------------- | ---------------------------------------------------------------------------- | | Plugin development guide | Create custom Rspress plugins using the Node.js plugin API and runtime hooks | | MDX component usage | Import and use React components in MDX documentation files | | Rspress 快速开始 | 从安装到本地预览，搭建 Rspress 文档站点的完整流程 | | 主题配置 | 自定义 Rspress 主题的导航栏、侧边栏、页脚和暗色模式 | | Home page (pageType: home) | Rspress documentation framework — fast, MDX-powered static site generator | **Bad:** | Description | Why | | ------------------------------------------------------- | ------------------------------------------------ | | “About plugins” | Too vague — which plugins? what about them? | | “This page explains how to configure the Rspress theme” | Wastes characters on “This page explains how to” | | “Learn everything about Rspress!” | Marketing fluff, says nothing specific | Documentation ------------- - Frontmatter fields: - Basic config (`root` option): - Full Rspress docs:
