Barcode Tools (decode, render, GTIN validate)

Each tool targets a distinct function: decoding, rendering, format listing, and GTIN validation. There is no meaningful overlap even though decode and validate both relate to barcode content.

All tools use a consistent snake_case verb_noun pattern (decode_barcode, list_formats, render_barcode, validate_gtin). This makes the intended action and target clear before reading the description.

With four tools, the server is tightly scoped to the core barcode operations of decode, render, validate, and format discovery. No tool feels redundant, and the count is appropriate for a focused utility server.

The server covers the primary barcode lifecycle: reading existing barcodes, creating new ones, validating GTINs, and enumerating supported formats. The render self-check and format matrix avoid dead ends, and no essential operation appears to be missing.
