"He's an agnostic about vendors" may seem logical. After all, we say "an expert" and "a specialist." But in standard workplace English, "agnostic" is an adjective in this sense.
"Agnostic" can also be a noun about religious belief. It often refers to a person who says that whether a god exists is unknown or cannot be known. That meaning does not fit a choice about vendors. For work decisions, use the adjective form.
Why the borrowed noun sounds wrong
"He's an agnostic about vendors" can confuse a reader. The noun points toward religious belief, even though the topic is vendor choice. A reader may pause before finding the intended meaning: he has no strong vendor preference.
- Incorrect: "She's an agnostic on the tooling decision." Correct: "She's agnostic on the tooling decision."
- Incorrect: "He's an agnostic about which framework we use." Correct: "He has no strong preference on which framework we use."

The natural business form is an adjective. State the person's view directly ("he's agnostic about vendors," "he has no strong vendor preference"). Or describe a system with a compound ("the service layer is vendor-agnostic"). Unlike "an expert," the workplace phrase does not need a noun.
- Correct, system version: "The service layer is vendor-agnostic" — no noun form needed, since the compound adjective already does the work.
The mistake in one line
The common mistake is using "an agnostic" as a short noun, like "an expert" or "a specialist." Here, that noun suggests a different meaning. In a vendor or tooling sentence, it may make the reader stop. Use an adjective or state the preference in plain words.
Practice scenarios
Practice using agnostic in situations like:
- rewriting a sentence that misuses "an agnostic" as a business noun
- choosing between an adjectival stance phrase and a compound for the same idea
- catching the noun-form mistake before it reaches a design doc or email
Useful practice phrases:
- "She's agnostic on [decision], not "she's an agnostic on [decision].""
- "He has no strong preference on [decision]."
- "The [system] is [noun]-agnostic."
"An agnostic" usually points to a question of belief. For a work choice, use the adjective.
