Sometimes specific words simply have to appear for an answer to be correct, compliant, or on-brand — a defined term, a mandated disclosure phrase, a required label, a regulated designation. The model, optimizing for fluent prose, will often paraphrase right past them. Term Penalty gives you a direct lever to require that vocabulary and dock any answer that skips it, turning 'this language must appear' from a hope into an enforced check.

## What it actually does

Where Key Term Penalty focuses on entities discovered in the source, Term Penalty gives you broader control over required terms — vocabulary you specify because your business or your regulator demands it. Answers missing the expected terms are scored down, nudging the system toward responses that include the language they must. It's a configurable expectation about what words an answer needs to contain, enforced at scoring time rather than hoped for at prompt time.

## Why business teams care

Compliance language is frequently non-negotiable. A response that omits a required disclosure, drops a mandated qualifier, or substitutes a casual phrase for a regulated term can create real liability — even when the underlying information is correct. Term Penalty makes required phrasing an enforced property of the output rather than something you audit for after the fact, which is the difference between catching a problem and preventing it.

## How to tune it in practice

Match the severity of the penalty to the consequence of the omission. For legally required phrasing — disclosures, qualifiers, defined terms — apply a hard penalty so answers without them simply don't pass. For brand or style preferences, a gentle nudge is enough to encourage consistency without rigidly forcing every response. Maintain the required-term lists deliberately, and revisit them whenever policy or regulation changes so the enforcement keeps pace with the rules.

## Common failure modes it prevents

The headline failure is the 'compliant content, non-compliant wording' answer — accurate information delivered without the mandated language, which in regulated contexts can be as problematic as being wrong. It also prevents quiet brand drift, where the assistant gradually substitutes informal or inconsistent terminology for the approved vocabulary across thousands of interactions until the voice no longer matches the standard.

## Where it fits in the stack

Term Penalty operates in the grounding-fidelity layer beside Key Term Penalty and the coverage controls. While those focus on faithfulness to the source, Term Penalty adds faithfulness to your standards — the words you require regardless of how any single source phrases things. Together they let you enforce both 'say what the source says' and 'say it using the language we're obligated to use.'

## Tuned to your standards

Strictness is fully configurable, so the same mechanism serves two very different masters: gentle reinforcement for style and brand consistency, and hard enforcement for legally required phrasing. One control, calibrated per use case, covers the full range from 'we'd prefer this wording' to 'this exact language must appear.'

> In regulated language, the exact word is the control. Missing it isn't a style choice.

## The takeaway

Term Penalty gives you a direct, tunable lever on required vocabulary — so answers consistently include the terms your business or regulator demands, enforced at the output rather than discovered in an audit.
