Scored across 10 tools
Each tool has a sharply defined purpose: base64 encode/decode are an obvious inverse pair, json_format vs json_minify vs json_validate are clearly separated by intent (pretty-print, strip, check), and hash_text, jwt_decode, csv_to_json, now, and uuid occupy distinct domains. No two tools could plausibly be selected for the same task.
Eight of ten tools follow a predictable snake_case verb_noun or domain_action pattern (base64_encode, json_validate, csv_to_json, hash_text). The outliers are 'now' and 'uuid', which are bare nouns/words with no verb, a minor but visible break in the convention.
Ten tools is a well-scoped set for a developer utility server: small enough to scan quickly, large enough to cover encoding, hashing, JSON, CSV, JWT, time, and IDs. Every tool corresponds to a real, common developer need with no filler.
The surface covers the main utility categories and provides inverse operations for base64, but pairing is asymmetric: csv_to_json has no json_to_csv, and there is no URL encode/decode, which are standard companions in a devutils set. These are workable-around gaps rather than dead ends.
