上下文成本
這是每次將伺服器的工具載入模型上下文時所消耗的約略 token 數量。數量越高，可用於其他工作的注意力就越少。

⚪decode_barcode(image_base64, formats)
Detect and decode all barcodes in an image. Input: base64-encoded image bytes (PNG/JPEG/WebP/anything sharp reads). Output: JSON array of {format, text}. Supports QR, Aztec, DataMatrix, Code128/39/93, EAN-13/8, UPC-A/E, ITF, PDF417, Codabar. Use formats filter to restrict results.

}🟢render_barcode(text, format, scale)
Render text as a barcode PNG. format: one of qr, aztec, datamatrix, code128, code39, code93, ean13, ean8, upca, itf, pdf417. Output: base64 PNG plus 'decoded' self-check flag (we decode our own render; upca intentionally verifies as zero-padded EAN-13). GTIN codes must have a valid mod-10 checksum.

}🟢validate_gtin(code)
