classify, extract, and summarize target three clearly distinct operations (classification, schema-based field extraction, summarization), and each _file variant is explicitly documented as the same operation with a file input source. There is no real ambiguity about which tool performs which action.

All names use a consistent snake_case verb pattern, with the _file suffix applied uniformly to denote the file-reading variant of each operation. The taxonomy is predictable and readable.

Six tools for three core text operations plus their file counterparts is tight and well-scoped; every tool earns its place with no redundancy beyond the intended input-source pairing.

The surface covers the three primary operations for both raw text and local files, forming a coherent lifecycle. Minor gaps exist (e.g. no batch, URL, or stdin input variants), but agents can work around them by reading content themselves.
