What problem does it solve? App Store and Google Play enforce different length limits, emoji rules, keyword fields, and locale codes, and copy that violates them gets rejected with vague messages. This Skill encodes the exact two-store rules so listing copy passes review on the first submission. ## Core Features & Use Cases - Two-store length and rule tables: Character limits for every field (name 30, short description 80, description 4000, keywords 100), plus ASC's no-emoji rule and keyword deduplication against name/subtitle. - Three-locale localization strategy: zh-Hant as source with en-US and ja as localized rewrites rather than literal translations, including per-market search-term selection. - Canonical directory layout: A metadata/ and play/ JSON structure compatible with asc metadata pull/push and gpc listing push, plus a rejection-fix table for common failures. - Use Case: You need App Store and Play descriptions in zh-Hant, en-US, and ja. The Skill produces emoji-free ASC copy, derives the Play variant, verifies character counts, and lays out files ready to push via asc and gpc. ## Quick Start Write App Store and Google Play listing copy for my app in zh-Hant, en-US, and ja using the store-listing rules and verify all character limits.
