MCP tool
在本機預覽圖片版位適配
sosoapi_prepare_asset_images從有權存取嘅 Workspace 原圖，在本機產生一至四個已指定版位嘅裁切、補邊或相同比例縮放 JPEG 預覽。支援靜態 PNG 同 baseline JPEG，最多 20 MiB／8,388,608 像素；不支援嘅色彩設定要先匯出 sRGB。回傳精確檔案、尺寸、提示同來源記錄，確認後先用 sosoapi_upload_asset 及返回嘅 upload_arguments 儲存。唔會發布。
閱讀 MarkdownProfiles 及連接方式
Profiles: core, full · Transports: stdio
Profile 只影響工具可見性，唔會授權。HTTP 冇本機檔案上傳。SOSOAPI_OUTPUT_SCHEMAS=1 會宣告輸出 schema；兩種模式都會回傳 structured results。
權限及改動
MCP annotations 只係發現提示，唔係存取控制保證；仍然有實際登入、角色、資源及能力檢查。
