Summary

Catches up es/fr/zh translations where the English source had newer content (missing sections, code blocks, list items) and removes a stale Tip that was deleted from the English quickstart.mdx.

Context

This repository has a single root commit, so per-file git timestamps could not be used to compute translation lag. Candidates were identified by comparing structural signals (heading counts, code-block counts, component opens) between each English *.mdx and its es/, fr/, and zh/ counterpart, then verified by inspecting the actual diff. Pure style/punctuation/whitespace differences and the localized <div id="..."> heading-wrapper pattern were treated as "no action needed."

Changes

Sorted by staleness — pages with the most missing content first. All translated additions follow the existing <div id="..."> wrapper convention used throughout the localized files.

Chinese (zh) — most stale

• zh/cli/commands.mdx — Added the entire ## mint workflow section (with mint workflow create, mint workflow list, mint workflow delete subcommands, shared flag table, examples, and YAML workflow file shape). The English file documents these commands but the zh translation jumped from mint analytics straight to mint config.
• zh/organize/settings-reference.mdx (flagged, not edited) — zh is missing ~40 reference subsections (navigation.global.tabs/anchors/dropdowns/versions/products, navigation.versions/tabs/anchors/dropdowns/products/groups/pages, favicon.light/dark, fonts.heading/body, the entire background.color/background.image tree, styling.codeblocks.theme/languages, the entire thumbnails block, errors.404.redirect/title/description, api.url, the entire api.mdx tree, etc.). 941 EN lines vs 646 zh lines. Too large to translate safely without human review.
• zh/ai/skillmd.mdx — Added the missing ## Agent card section covering the /.well-known/agent-card.json endpoint, A2A schema fields table, custom-domain behavior, reverse-proxy <Note>, and MCP cross-reference.
• zh/api-playground/openapi-setup.mdx — Added the missing ## Let visitors download your spec section (contextual menu config, download-spec JSON example, auth/userAuth behavior). es/fr already have this section.
• zh/ai/markdown-export.mdx — Added the missing ## Authentication section with the .md URL authentication-mode table. es/fr already have this section.
• zh/create/text.mdx — Added the missing ## Comments section covering {/* ... */} MDX comment syntax and the <Warning> against <!-- ... -->.
• zh/create/reusable-snippets.mdx — Added the missing "Variables also interpolate inside fenced code blocks" paragraph plus the two example code blocks (shared/install-snippet.mdx and the importing destination file).
• zh/optimize/seo.mdx — Expanded ### Set a canonical URL into Global canonical + Per-page canonical subsections (with frontmatter YAML example and the <Note> about /src/_props), and added the missing canonical bullet to the per-page meta tag list.
• zh/quickstart.mdx — Removed the stale <Tip> about replacing github.com with mintlify.com (the English source removed this).
• zh/changelog.mdx (flagged, not edited) — Missing the entire May 29, 2026 <Update> entry (Editor, Editor agent, Workflows, API playground, Admin MCP, Agent discoverability, Improvements, Bug fixes sections). Translating a ~70-bullet release note is too large for an automated pass.
• zh/editor/pages.mdx (flagged, not edited) — English file was substantially rewritten (new headings: Block actions, Table of contents, Code block options, Pages deleted via Git, Add media, Images and videos, Light and dark image variants, Embed external media; replaces previous Modo visual/Modo Markdown/Personaliza la apariencia structure). Needs human translation.
• zh/organize/navigation.mdx (flagged, not edited) — English ## Languages section converted from <CardGroup> to a Markdown table of language codes. zh still uses the CardGroup format.

Spanish (es)

• es/quickstart.mdx — Removed the stale <Tip> about replacing github.com with mintlify.com (deleted from English source).
• es/changelog.mdx (flagged, not edited) — Missing the May 29, 2026 <Update> entry. Needs human translation.
• es/editor/pages.mdx (flagged, not edited) — Same rewrite as zh above. Needs human translation.
• es/organize/navigation.mdx (flagged, not edited) — Same CardGroup → table change as zh.

French (fr)

• fr/quickstart.mdx — Removed the stale <Tip> about replacing github.com with mintlify.com (deleted from English source).
• fr/changelog.mdx (flagged, not edited) — Missing the May 29, 2026 <Update> entry. Needs human translation.
• fr/editor/pages.mdx (flagged, not edited) — Same rewrite as zh. Needs human translation.
• fr/organize/navigation.mdx (flagged, not edited) — Same CardGroup → table change as zh.

Missing files (flagged for human review)

Translations for these English pages do not exist at all. Creating them is out of scope for this lag-sync pass:

• deploy/gitlab-self-hosted.mdx — missing in es, fr, zh
• editor/branching-and-publishing.mdx — missing in es, fr, zh
• editor/share-a-preview.mdx — missing in es, fr, zh
• editor/tutorial.mdx — missing in es, fr, zh
• snippets/counter.mdx, snippets/custom-subpath-propagating.mdx, snippets/gitlab-workflow-setup.mdx, snippets/icons-optional.mdx, snippets/icons-required.mdx, snippets/skill-mcp-prompt.mdx, snippets/vercel-json-generator.mdx — missing in es, fr, zh
• ai/mintlify-mcp.mdx — missing in zh
• credits.mdx — missing in zh
• guides/use-workflows.mdx — missing in zh
• optimize/search.mdx — missing in zh
• workflows/{create,index,manage,reference}.mdx — missing in zh

Validation

• mint validate — only the pre-existing docs.json download-spec enum warning, unchanged by this PR.
• mint broken-links — clean (the new mint workflow section in zh/cli/commands.mdx links to /workflows since zh/workflows/ does not exist; matches how other zh pages reference English-only sections).
