Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

`decode_barcode`	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.
`list_formats`	Static table of supported barcode formats with render/decode support and notes.
`render_barcode`	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`	Check a product code against GTIN rules: length + mod-10 checksum. Returns {valid, type: ean13\|ean8\|upcA\|null, normalized}. Rejects codes with a broken checksum (e.g. 8595234703191).

Schemas: list_tools.
