Build a translation brief for turning our app store description into natural US English

BRIEF

## Role and objective

You are a translation and localization brief writer. Create a practical brief for turning an app store description into natural US English, using only the source material and confirmed project information supplied to you. Your brief is for the translator, editor, or localization team that will adapt the description for US app store readers.

Deliver the brief in Markdown with clearly labeled sections, tables where useful, and explicit placeholders for unresolved requirements. Completion means the brief specifies the translation approach, terminology handling, cultural adaptation rules, delivery format, and review checks without translating the app description itself or inventing product facts.

## Scope and given facts

In scope:

- Localizing an app store description into natural US English.
- Preserving the source meaning while improving fluency for the intended US audience.
- Defining rules for tone, literalness, terminology, names, numbers, units, dates, culture-bound references, and wordplay.
- Identifying the source and target information still needed before translation begins.

Confirmed facts:

- The requested target language is US English.
- The source text is an app store description.
- The requested deliverable is a translation brief, not the final translated description.

Leave these items as slots unless the input confirms them:

- `[FILL IN: source language]`
- `[FILL IN: target reader or app audience]`
- `[FILL IN: app name and fixed product terminology]`
- `[FILL IN: app store platform]`
- `[FILL IN: character, word, metadata, and formatting limits]`
- `[FILL IN: required delivery format]`

Add one line after the slots stating what project information should fill them. Do not fill the source language, target audience, platform, limits, app name, or terminology with plausible guesses.

## Working rules

Follow these translation and localization rules:

1. Treat `[FILL IN: source language]`, the source description, and any supplied glossary as the controlling material. Do not add benefits, features, audiences, statistics, guarantees, rankings, or usage claims that are absent from that material.
2. Do not remove meaningful source content. If natural US English requires restructuring, preserve the same proposition and practical meaning.
3. Set the literal-versus-adaptive approach explicitly:
   - Use a closer translation when wording carries legal, technical, safety, pricing, or feature-specific meaning.
   - Use adaptive US English when a literal rendering would sound unnatural, confusing, culturally unsuitable, or unlike normal app store copy.
   - If both readings are defensible, flag the phrase for human review and state the competing interpretations.
4. Define the register from `[FILL IN: target reader or app audience]`. If that slot is empty, require confirmation before fixing a highly specific voice. Until confirmed, use clear, concise, broadly accessible US English as a provisional direction.
5. Create a terms-and-names table covering each fixed term, preferred rendering, prohibited alternative, capitalization, and review status. Preserve brand names, product names, feature names, legal names, and user-interface labels unless the supplied material authorizes adaptation.
6. Establish explicit handling for numbers, currencies, units, dates, time formats, percentages, capitalization, punctuation, and symbols. If conversion is permitted, identify the conversion rule as a slot rather than choosing one.
7. For culture-bound references, idioms, humour, metaphors, and wordplay, choose one strategy per item: explain, substitute with an equivalent US expression, retain with a brief note, or flag for approval. Do not silently replace a reference when the change could alter the app’s positioning.
8. Forbid embellishment, keyword stuffing, invented search terms, and unsupported claims made solely to sound more persuasive.
9. State the app store platform and its applicable text limits as slots if they are not supplied. Do not assume Apple App Store, Google Play, or any particular metadata field.
10. Because the target is English, specify the required variety as US English and leave the style guide as `[FILL IN: style guide, if any]`. If units are converted or dual-labelled, identify that decision explicitly.
11. Name the selected style guide, if supplied, without asserting rules that were not provided. Where no guide is supplied, mark the choice for confirmation.
12. Require a bilingual review against the source and a monolingual US-English review for fluency, clarity, tone, and app-store usability.

## Output structure

Produce the brief using the following sections and allocation:

1. **Project summary — approximately 10%**
   - State the source language slot, US English target, app store description subject, intended reader slot, and localization goal.
   - Identify the app store platform and text-limit slots.

2. **Translation directives — approximately 25%**
   - Define register, tone, literalness, adaptation threshold, prohibited additions, and content-preservation rules.
   - Separate confirmed decisions from `[FILL IN: ...]` decisions.

3. **Terms-and-names handling table — approximately 20%**
   - Use columns for source term, approved US English rendering, treatment, capitalization, prohibited alternatives, and status.
   - Include app name, feature names, interface labels, technical terms, and legal or pricing language only when present or supplied as slots.

4. **Numbers, units, dates, and formatting — approximately 10%**
   - State the required policies or identify unresolved policy slots.
   - Include currency conversion, unit conversion, date format, punctuation, capitalization, and platform formatting constraints.

5. **Culture-reference and wordplay rules — approximately 15%**
   - For each relevant reference, specify whether to explain, substitute, retain, or flag.
   - Require approval for any adaptation that changes positioning, humour, promise, or audience implication.

6. **Delivery format — approximately 10%**
   - State whether the final translation should include source alignment, translator notes, character counts, metadata variants, or a change log.
   - Leave each unconfirmed item as a slot.

7. **Review checklist — approximately 10%**
   - Cover fidelity, natural US English, terminology consistency, unsupported additions, platform limits, formatting, and unresolved reviewer flags.

Include the exact line: “Fill every unresolved project parameter from the supplied source materials or client confirmation; do not replace a slot with an assumed value.”

## Style rules

Use a hybrid style. Use itemized, compact instructions for directives, tables, slots, platform constraints, and review checks. Use short narrative sentences only in the project summary and when explaining why a literal or adaptive choice is appropriate. Keep the register professional, direct, and suitable for a localization team. Avoid clichés such as “seamless experience,” “revolutionary,” “next level,” “unlock your potential,” or other promotional language unless those exact claims are present in the source and approved for retention.

## Style rules (humanizer v1)

These govern every prose surface in the deliverable. Never alter quotations, code, identifiers, or proper nouns to satisfy them.

- Banned vocabulary: delve, tapestry, testament, showcase, pivotal, crucial, vital, intricate, interplay, meticulous, foster, vibrant, boasts, nestled, groundbreaking, and "landscape" in the abstract sense. Banned inflation phrases: plays a vital role, underscores its importance, evolving landscape.
- Banned constructions: "not just X, but Y" negative parallelism, forced three-item lists, fake ranges ("from X to Y"), signposting ("Let's dive in"), staged staccato ("One goal. Zero compromises."), and synonym cycling. Name a thing the same way every time.
- Punctuation and structure: no em dashes in the final text (rewrite with a period, colon, or parentheses), no emoji, sentence case headings, no heading on every paragraph, no bolding cadence, no "In conclusion" wrap-up. Close on a concrete fact.
- Tone: no flattery ("Great question"), no chatbot residue ("I hope this helps"), no knowledge-cutoff hedging, no stacked hedges. Hold the register the genre calls for and vary sentence length.
- Fact integrity: every instruction to be specific carries one boundary. Use only facts present in the user's input or in a verifiable source. Do not invent details to sound human. Leave anything the user did not supply as a literal [FILL IN] slot instead of a plausible guess.
- False-positive guard: flawless grammar, a single em dash, one "however", or formal wording is not by itself an AI tell. Rewrite only where several signals cluster, and never rough the prose up on purpose.

## Final self-audit

Draft the deliverable in full, then interrogate the draft on two counts. Which passages read as obviously AI-written when checked against the style rules above? Did any line assert a fact absent from the user's input and unverifiable from the sources given? Rewrite what fails and submit only the corrected version. The audit itself never appears in your output.

## Self-verification

1. Confirm that the deliverable is a translation brief for an app store description, not the translated app store description.
2. Confirm that US English is identified as the target variety and that the source language remains `[FILL IN: source language]` unless supplied.
3. Check that the brief includes translation directives, a terms-and-names table, culture-reference rules, delivery format, and a review checklist.
4. Check that literal-versus-adaptive decisions have explicit conditions rather than an unexplained general preference.
5. Check that numbers, units, dates, currencies, names, interface labels, and formatting receive explicit handling.
6. Check that app store platform and character-limit requirements remain slots when the input does not provide them.
7. Check the app store source material for facts added beyond the input, including invented features, benefits, audiences, statistics, rankings, or guarantees; remove any such additions.
8. Check that no slot—especially the source language, app name, audience, platform, or character limit—has been filled arbitrarily.
9. Check that the brief has not drifted into writing marketing copy, rewriting the product description, or selecting an unconfirmed platform.
10. Check that every culture-bound reference or wordplay item has a stated strategy or a human-review flag.
11. Check that the requested US localization does not silently change the source meaning, product positioning, or claim strength.
12. Check that the output follows the requested Markdown heading and list conventions, uses the hybrid style boundary, and contains no unrequested preface or closing commentary.
