YOUR MISSION

Produce a translated version that:

Reads as if originally written in the target language
Preserves brand voice integrity -- culturally adapted
Maintains 100% citation accuracy -- every URL, DOI, reference unchanged
Adapts SEO for target market -- keywords researched for target language search behavior
Contains zero AI telltale phrases in the target language
Respects cultural norms -- dates, currencies, formality, idioms

Critical Rules:

NEVER modify citation URLs, DOIs, ISBNs, or reference identifiers
NEVER translate brand names, product names, or email addresses
NEVER change factual content -- data, statistics, claims must be identical
ALWAYS classify elements before translating (immutable vs translatable)
ALWAYS verify citation count matches source after translation

EXECUTION STEPS

Step 1: Element Classification

Separate all content into translatable and immutable categories before touching any text.

1.1 Immutable Elements (DO NOT TRANSLATE)

Scan and tag with IDs:

Citation URLs (all links)
Brand names and product names
Proper nouns (people)
Technical identifiers (DOIs, ISBNs)
Code snippets
Contact information (emails, phone numbers)

1.2 Translatable Elements

Tag everything else:

Document structure (title, H2/H3 headings)
Body content (all paragraphs)
Meta elements (meta title, meta description, URL slug)
Bibliography titles (translate with [original in brackets])
Alt text for images

1.3 Element Registry

Create a master registry linking every element to its translation instruction (DO NOT TRANSLATE / TRANSLATE / TRANSLATE + preserve keyword / TRANSLATE with char limit).

Step 2: Localization Strategy Selection

Level 1: Literal Translation

Word-for-word where possible
Preserve exact document structure (same sections, paragraphs, sentences)
Do NOT adapt cultural references, idioms, or humor
Convert date/currency/number formats to target locale only

Level 2: Adapted Translation (Recommended)

Translate meaning with cultural adaptation
Preserve document structure (same sections, argument flow)
ADAPT cultural references, idioms, expressions to target language equivalents
ADJUST formality to target language defaults (from multilingual-patterns.json)
CONVERT dates, currencies, numbers to target locale

Cultural adaptation examples:

Element	English	Spanish (Adapted)	Reason
Date	"March 15, 2026"	"15 de marzo de 2026"	DD/MM standard
Currency	"$2.5 million"	"2,5 millones de dolares"	Comma decimal
Idiom	"hit the ground running"	"arrancar con fuerza"	Direct translation nonsensical
Formality	"you should consider"	"es recomendable considerar"	Spanish defaults to formal

Level 3: Transcreated Translation

Preserve core message and intent, but REBUILD for target market
MAY restructure sections for cultural logic flow
MAY replace examples with locally relevant equivalents
MAY adjust tone significantly (e.g., American casual -> Japanese formal)
MUST preserve all factual claims, data points, and citations
Flag all structural changes in translation report

Step 3: Brand Voice Mapping

Load voice mapping from config/multilingual-patterns.json for target language.

Each brand personality trait maps differently across languages:

Trait	Mapping Approach
Authoritative	Definitive statements, data-leading paragraphs, formal register
Conversational	Natural phrasing per language norms (not English-casual transplanted)
Witty	Culturally appropriate humor -- some languages (ja) prefer understated irony over direct wit
Data-driven	Statistics-forward, same across all languages
Warm	Culturally calibrated empathy expressions

Language-specific rules:

Japanese: Avoid direct wit in professional content; use appropriate keigo (honorific level)
German: Compound words natural; precision > brevity; formal "Sie" default
Arabic: Formal register default; eloquent flowing sentences; avoid very short fragments
Korean: Honorific endings match audience seniority; more indirect recommendations
French: Formal "vous" for business; elegant phrasing; wordplay translates well

Verify voice mapping per section: register consistency, data-leading style, definitive assertions, terminology consistency, tone match.

Step 4: Translation Execution

4.1 With DeepL MCP

Send source text section by section
Receive machine translation baseline
Refine for brand voice (Step 3 mapping)
Adapt cultural references (Step 2 level)
Restore immutable elements (verify against registry)
Apply target language humanization (remove AI patterns)

DeepL settings: Formality matches brand, preserve formatting, XML tag handling for immutable elements, no sentence splitting.

4.2 Without DeepL (Native Translation)

Read source section, understand core meaning
Compose in target language per localization level
Apply brand voice mapping
Verify immutable elements untouched
Check cultural adaptation requirements

Section processing order: Title (H1) -> Meta title/description -> Introduction -> Body sections (in order) -> Conclusion -> Bibliography titles -> Alt text

For each section, document: source text, target text, immutable elements preserved, voice check, cultural adaptations applied.

Step 5: SEO Adaptation

5.1 Keyword Research for Target Language

Do NOT simply translate keywords. Research actual target market search terms:

Direct translation may differ from actual search behavior
Select the higher-volume natural search term

Language-specific notes:

German: compound words dominate search
Spanish: Spain vs Latin America search differences
Japanese: mix of katakana loanwords and native terms
Chinese: Simplified (mainland) vs Traditional (Taiwan/HK)
French: France vs Quebec differences

5.2 Meta Tag Translation

Translate within character limits. Adjust for language expansion:

German: +15-25% longer than English
Spanish: +10-15% longer than English
Chinese/Japanese: fewer characters, same semantic content

If meta title exceeds 60 chars: shorten while preserving primary keyword and brand name.

5.3 Keyword Density Verification

After translation, verify primary and secondary keyword density within target ranges (1.5-2.5% primary, 0.5-1.5% secondary). Variance from source must be within +/- 0.5%.

Step 6: Citation Preservation

Zero tolerance for errors.

URL Verification: Compare source and target citation URL lists. Every URL must match exactly. Report X/X preserved (must be 100%).
Bibliography Title Translation: Translate titles with original preserved in brackets. Journal names, author names, volume/issue/pages are immutable.
Inline Citation Format: Verify (Author, Year) pattern preserved identically in target.

Step 7: Quality Verification

7.1 Readability Check

Benchmarks per language:

Language	Metric	Article Target	Blog Target
Spanish	Fernandez-Huerta	55-70	70-80
French	Kandel-Moles	55-70	70-80
German	Flesch (German)	40-60	60-70
Japanese	Sentence length	35-45 chars/sentence	25-35
Arabic	ARI (adapted)	Grade 10-12 equiv	Grade 8-10

7.2 Brand Voice Rating

Rate on 5 criteria (each 0-10): register consistency, data-leading paragraphs, definitive assertions, terminology consistency, tone match. Overall must be >= 8.0/10.

7.3 AI Pattern Check (Target Language)

Scan for target language AI telltale phrases from config/multilingual-patterns.json > ai_pattern_removal > {lang}. Replace any found with natural alternatives. Must reach 0 detected.

7.4 Back-Translation Spot Check

Translate 3-5 key sentences back to source language. Verify meaning preserved for each. Document source -> target -> back-translated -> meaning preserved (yes/no).

7.5 Keyword Density Final Check

Verify primary and secondary keyword density within tolerance (+/- 0.5% of target range).

OUTPUT FORMAT

Deliver:

Full translated content with all formatting, citations, and structure preserved
Translation Report containing:
- Element classification: total elements, immutable count, translated count, preservation rate
- Brand voice: source traits, target mapping, score per criterion, overall rating
- Citation integrity: source/target count, URL preservation %, inline format match, bibliography titles translated
- SEO adaptation: meta title/description (source vs target with char counts), URL slug, keyword density
- Quality metrics: readability (source vs target grade), voice rating, AI patterns detected, back-translation results, word count change
- Cultural adaptations applied: table of element/source/target/reason
- Composite Translation Score: X/10

QUALITY GATE

All must pass:

If any gate fails: Auto-retry the affected section (max 2 retries). If persistent: flag for human review. Never auto-approve content with citation errors.

MCP INTEGRATIONS

Google Drive (Required) -- Read source, store translated output
DeepL (Optional, npx: @anthropic-ai/deepl-mcp-server) -- Machine translation baseline. When not connected, agent handles all translation natively. Fallback is seamless.

EDGE CASES

Case	Handling
RTL Languages (Arabic)	Document structure reverses visually but logical order preserved. URLs remain LTR. Numbers written LTR.
CJK Languages (Chinese, Japanese, Korean)	Character count replaces word count. Keyword density by character frequency. Meta tag limits may need adjustment.
Regional Variants	es-es vs es-latam (ordenador vs computadora), pt-pt vs pt-br, fr-fr vs fr-ca, zh-cn vs zh-tw
Very Short Content (<500 words)	Skip back-translation. Keyword density tolerance +/- 1.0%. Full element classification still required.
Very Long Content (>5000 words)	Process in 500-word chunks. Cross-reference terminology consistency. Back-translation: 5-7 sentences.
