description	Align Rspress heading anchor IDs between English and Chinese docs. Use for MDX `\{#...}` anchors, shortened hashes, redundant anchors, or dead links.

Add Doc Anchor IDs

Use this skill for Rspress docs mirrored under website/docs/en and website/docs/zh.

Rules

• Treat the English document as the source for stable anchor IDs.
• If an English heading has 4 words or fewer, use the default Rspress anchor generated from the English heading.
• If an English heading has more than 4 words, choose a shorter semantic anchor ID and add that same custom ID to both English and Chinese headings.
• Do not add custom IDs that match Rspress default output. For example, keep ### parallel, not ### parallel \{#parallel}.
• In Chinese docs, add a custom ID only when the Chinese default anchor would differ from the desired English ID.
• In Chinese docs, remove custom IDs from pure English headings when the custom ID equals the Rspress default.
• MDX custom anchor syntax must be escaped: \{#anchor-id}.
• Keep changes limited to .md/.mdx documentation files unless the user explicitly asks otherwise.
• Do not add persistent validation or update scripts as part of this skill's work.

Workflow

1. Inspect the current branch and work tree before editing:

   git branch --show-current
   git status --short
   

2. Find relevant custom anchors and hash links:

   rg -n -F '\{#' website/docs/en website/docs/zh --glob '*.mdx'
   rg -n "\]\([^)]*#[A-Za-z0-9_-]+[^)]*\)" website/docs/en website/docs/zh --glob '*.mdx'
   rg -n "href=['\"][^'\"]*#[A-Za-z0-9_-]+" website/docs/en website/docs/zh --glob '*.mdx'
   

3. For each edited or referenced document pair, compare the English file with its Chinese counterpart at the same locale-relative path:

   website/docs/en/guide/configuration/rsbuild.mdx
   website/docs/zh/guide/configuration/rsbuild.mdx
   

4. For each heading pair, decide the desired anchor:

   • English heading has an intentional custom ID: use that ID in both locales.
   • English heading has no custom ID and has 4 words or fewer: use the English default ID.
   • English heading has no custom ID and has more than 4 words: choose a shorter semantic ID and add it to both locales.
   • Chinese heading is pure English and its custom ID equals the default ID: remove the custom ID.

5. Apply edits directly in the affected .md/.mdx files. Examples:

   ## 指定配置文件 \{#specify-config-file}
   

   ## Dev server and client communication \{#dev-server-client-communication}
   
   ## 开发服务器与客户端通信 \{#dev-server-client-communication}
   

6. Update all links that point to an old hash:

   [指定配置文件](/guide/configuration/rsbuild#specify-config-file)
   

7. Validate the result:

   git diff --check
   changed_docs=$(git diff --name-only -- '*.md' '*.mdx')
   if [ -n "$changed_docs" ]; then
     printf '%s\n' "$changed_docs" | xargs pnpm dlx cspell --no-progress
     printf '%s\n' "$changed_docs" | xargs pnpm exec rs fmt
   fi
   

8. If there is an existing repository command for docs link checking or docs build, run it. Otherwise, inspect changed hashes with rg and verify each target heading exists in the target file.

Rspress Anchor Notes

• Rspress/GitHub-style anchors lowercase headings and remove punctuation such as . from API names; verify these IDs instead of guessing.
• Some characters are preserved by the actual Rspress slugger, such as underscores in BASE_URL; avoid guessing when a link already works.
• Duplicate headings get numbered suffixes like #environment-api-1. Preserve those suffixes when the English page relies on them.
• A custom anchor changes the actual target ID, so update same-page and cross-page links that still point to the old generated hash.
