# Blog Multilingual, One-Command International Publishing
The flagship multilingual orchestrator. Combines blog writing, translation,
cultural adaptation, and full international SEO into a single command.
Produces publication-ready blog posts in every target language with hreflang
tags, localized JSON-LD schema, and CMS-integration metadata.
> Adapted from `claude-blog-multilingual` by Chris Mueller (AI Marketing Hub
> Pro Hub Challenge submission, March 2026, scored 85/100 Proficient).
> Original: https://github.com/Chriss54/multilingual-int
> This port removes the original `curl | bash` installer and credential
> handling flagged in the audit, integrates as core skills, and uses the
> shared cultural-adaptation reference under `blog-translate/references/`.
## Dependencies
Invoked internally by this orchestrator:
| Component | Source | Required |
|-----------|--------|----------|
| `blog-write` | claude-blog (this plugin) | Yes |
| `blog-translate` | claude-blog (this plugin) | Yes |
| `blog-localize` | claude-blog (this plugin) | Yes (when `--localize` is on, default) |
| `seo-hreflang` | claude-seo (sibling plugin) | No, falls back to a self-contained generator |
If `seo-hreflang` is not installed, the orchestrator emits hreflang tags using
its own minimal generator (Phase 5 below) and notes the limitation in the
delivery summary. Hreflang validation in that case is structural only, not the
deeper validation `seo-hreflang` provides.
## Command Syntax
```
/blog multilingual <topic> --languages <lang1,lang2,...> [--source <lang>] [--no-localize] [--format <md|mdx|html>]
```
| Argument | Required | Default | Description |
|----------|----------|---------|-------------|
| `<topic>` | Yes | , | Blog topic or working title |
| `--languages` | Yes | , | Comma-separated ISO 639-1 codes (e.g. `de,fr,es,ja,pt-BR`) |
| `--source` | No | `en` | Source language to write the original in |
| `--no-localize` | No | off | Skip cultural adaptation (translation only) |
| `--format` | No | auto | Output format: `md`, `mdx`, or `html` |
If `--languages` is missing, ask the user once before running anything:
"Which languages should the blog be published in? Provide ISO 639-1 codes
separated by commas (e.g., `de,fr,es,ja,pt-BR`). The post will be written in
`<source>` first, then translated."
## Workflow
### Phase 1: Configuration
1. Parse arguments. Extract topic, target languages, source, format.
2. Validate each language code against ISO 639-1 (region suffixes like
`pt-BR`, `es-MX`, `zh-TW` are also accepted).
3. Detect output format from the project (frontmatter convention, file
extensions, framework hints) or use `--format`.
4. Resolve source language. If a target language equals `--source`, drop it
from the translation list with a notice.
5. Create the output directory inside the current working directory:
```
multilingual/
{source-lang}/
{lang-1}/
{lang-2}/
...
```
Output MUST stay inside the project root. Never write outside the cwd.
Progress: `Phase 1: Configuration complete, [N] languages selected ([codes])`
### Phase 2: Write Original Blog
Invoke the `blog-write` sub-skill (route through `/blog write` so all
existing rules apply: template auto-selection, sourced statistics, citation
capsules, FAQ schema, internal-link zones, charts, image embedding). Pass the
topic and any blog-write parameters surfaced by the user.
Save the original to `multilingual/{source-lang}/{slug}.{ext}`.
Progress: `Phase 2: Original written, multilingual/{source-lang}/{slug}.{ext}`
### Phase 3: Translate to All Target Languages
For each target language, invoke `blog-translate`:
- Input: the original blog post produced in Phase 2.
- Target: the specific language code.
- Run targets in parallel where the runtime supports it (one Task per
language) to reduce wall-clock time.
Save translations to `multilingual/{lang}/{localized-slug}.{ext}`.
Progress: `Phase 3: Translating to [lang] ([X]/[N])` per language, then
`Phase 3: All translations complete`.
### Phase 4: Cultural Adaptation
If `--no-localize` is NOT set, invoke `blog-localize` for every translated
post:
- Input: the translated blog post.
- Locale: the target language or region code.
- Run in parallel.
Update files in place. The localizer swaps brand examples, adapts CTAs,
substitutes legal references, and adjusts formality. See
`../blog-localize/SKILL.md` for the full adaptation pass.
Progress: `Phase 4: Cultural adaptation complete for [N] languages`.
### Phase 5: International SEO Generation
Generate three artifacts plus localized schema. If the `seo-hreflang` skill
from claude-seo is installed, delegate validation to it. Otherwise use the
self-contained generator below.
#### 5a. Hreflang Tags (HTML)
Copy-paste ready tags for `<head>`:
```html
<!-- Hreflang tags. Paste into <head> of each language version. -->
<link rel="alternate" hreflang="{source}" href="{source-url}" />
<link rel="alternate" hreflang="{lang-1}" href="{lang-1-url}" />
<link rel="alternate" hreflang="{lang-2}" href="{lang-2-url}" />
<link rel="alternate" hreflang="x-default" href="{source-url}" />
```
Rules (mirrored from `seo-hreflang`):
- Every page references all alternates including itself (self-referencing).
- `x-default` points to the source-language version.
- All URLs use the same protocol (HTTPS) and trailing-slash convention.
- Bidirectional: every relationship is reciprocal.
Save to `multilingual/hreflang-tags.html`.
#### 5b. Hreflang Sitemap Fragment
```xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
xmlns:xhtml="http://www.w3.org/1999/xhtml">
<url>
<loc>{source-url}</loc>
<xhtml:link rel="alternate" hreflang="{source}" href="{source-url}" />
<xhtml:link rel="alternate" hreflang="{lang-1}" href="{lang-1-url}" />
<xhtml:link rel="alternate" hreflang="x-default" href="{source-url}" />
</url>
<!-- Repeat one <url> block per language version -->
</urlset>
```
Save to `multilingual/hreflang-sitemap.xml`.
#### 5c. Hreflang Map (JSON)
Machine-readable mapping for CMS integration:
```json
{
"sourceSlug": "how-to-avoid-ai-slop",
"sourceLanguage": "en",
"generatedDate": "YYYY-MM-DD",
"versions": [
{
"lang": "en",
"slug": "how-to-avoid-ai-slop",
"file": "en/how-to-avoid-ai-slop.md",
"title": "How to Avoid AI Slop in 2026",
"description": "..."
},
{
"lang": "de",
"slug": "wie-man-ki-slop-vermeidet",
"file": "de/wie-man-ki-slop-vermeidet.md",
"title": "KI-Slop vermeiden in 2026",
"description": "..."
}
],
"hreflang": {
"method": "html",
"x-default": "en"
}
}
```
Save to `multilingual/hreflang-map.json`.
#### 5d. Localized Schema (Optional)
If the user asks, or if a frontmatter `schema: true` flag is present, attach
or update JSON-LD on every language version with `inLanguage` and
`translationOfWork` fields:
```json
{
"@context": "https://schema.org",
"@type": "BlogPosting",
"headline": "[Localized title]",
"description": "[Localized description]",
"inLanguage": "[lang-code]",
"isPartOf": { "@type": "Blog", "inLanguage": "[lang-code]" },
"translationOfWork": {
"@type": "BlogPosting",
"inLanguage": "[source-lang]",
"url": "[source-url]"
}
}
```
Use the existing `/blog schema` sub-skill if richer schema (FAQ, Person,
Breadcrumb) is wanted on each version.
### Phase 6: Delivery Summary
```
## Multilingual blog complete: [Title]
### Original
- Language: [source]
- File: multilingual/{source}/{slug}.{ext}
### Translations
| Language | File | Localized | Keywords adapted |
|----------|------|-----------|------------------|
| de | multilingual/de/{slug}.md | yes | [N] |
| fr | multilingual/fr/{slug}.md | yes | [N] |
| es | multilingual/es/{slug}.md | yes | [N] |
### International SEO assets
- multilingual/hreflang-tags.html
- multilingual/hreflang-sitemap.xml
- multilingual/hreflang-map.json
- Localized schema embedded per version (if requested)
### Total
- [N] posts in [N] languages
- [N] SEO assets generated
### Next steps
- Replace `{url}` placeholders in hreflang tags with your real URLs.
- Merge `hreflang-sitemap.xml` into your existing sitemap.
- Run `/blog locale-audit multilingual/` to verify completeness.
- Resolve `[INTERNAL-LINK]` placeholders with locale-specific URLs.
- If claude-seo is installed, run `/seo hreflang multilingual/` for
deeper validation.
```
## Cross-References
| When | Run |
|------|-----|
| To regenerate or reword the source | `/blog write <topic>` |
| To translate one existing file only | `/blog translate <file> --to <codes>` |
| To deepen cultural fit on one file | `/blog localize <file> --locale <code>` |
| To audit a multilingual directory | `/blog locale-audit <directory>` |
| For deeper hreflang validation | `/seo hreflang <directory>` (claude-seo, optional) |
## Error Handling
| Scenario | Action |
|----------|--------|
| `blog-write` missing | Error: "This skill requires `blog-write`. Reinstall claude-blog." |
| One translation fails | Complete the rest, report partial results, suggest a retry command |
| Source language equals a target | Skip that target, log a notice |
| More than 10 target languages | Warn about wall-clock time, proceed if confirmed |
| `seo-hreflang` not installed | Use the self-contained generator, note it in the summary |
## Commands Recap
| Command | Purpose |
