SnapOtterandGitHub f858c4cea0 feat: clearer, disambiguated tool names across all surfaces (#520)
Renames 18 ambiguous or hard-to-search tool names so image tools self-qualify like the other modalities ("Compress" becomes "Compress Image"), and cleans up a few awkward names. Propagated across search (constants.ts), display (en.ts + 20 locales), the OpenAPI base spec + 20 locale specs, and the docs tool-page headings in 21 languages. Removes the duplicate "Normalize Audio" summary shared by the video and audio endpoints. Tool ids and routes are unchanged, so no API paths or bookmarks break.

Notes

  • 正值會增加音量;負值會降低音量。
  • 較大的正增益可能造成削波。請使用 normalize-audio 進行不損音量的響度平衡。
  • 輸出通常會保留輸入的容器格式。AAC 輸入會寫成 M4A,而不支援的僅可解碼輸入則會退回為 MP3。
