The documented best practices for prompt template text: a role with a goal, an Instructions: section in triple quotes, explicit format and length, one consistent plain-language style, an instruction to generate only the content, staying inside the grounded data, and iterating with real records and user feedback.

**Official exam objective:**

> Explain how to implement best practices for writing effective prompts.

## What the exam expects

- Apply the documented best practices when writing a prompt template: role and goal, a clear task, delimited instructions, output format and length, and one consistent style.
- Diagnose a bad response (generic text, process narration, echoed instructions, inconsistent tone, invented facts) and pick the prompt change that fixes it.
- Reduce hallucination with instructions that keep the model inside the grounded data and handle missing values.
- Explain why plain, concise wording beats copied jargon, and why you start from example templates and iterate with real records and user feedback.
- Key terms: **prompt instructions** (the natural-language task description in the template); **grounding** (adding relevant Salesforce data so the response isn't generic); **delimiter** (the `Instructions:` line plus triple quotes that separates directions from context); **hallucination** (a response with false information not in any source); **meta-commentary** (text about how the model wrote the content instead of the content itself).

## Key facts

| Fact | Detail | Source |
|---|---|---|
| Role play | Ask the LLM to play a character, then define that character's goal | [Best Practices](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_best_practices.htm&language=en_US&type=5) |
| Instructions delimiter | `Instructions:` on a separate line, directions surrounded by triple quotes | [Best Practices](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_best_practices.htm&language=en_US&type=5) |
| Stopping process narration | Instruct the LLM to generate only the expected type of content | [Best Practices](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_best_practices.htm&language=en_US&type=5) |
| Wording | Concise, natural language; avoid industry jargon and technical terms | [Best Practices](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_best_practices.htm&language=en_US&type=5) |
| Style | Choose one style and stick to it for consistent responses | [Best Practices](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_best_practices.htm&language=en_US&type=5) |
| Starting point | A template from the Example Prompt Template Library, customized | [Best Practices](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_best_practices.htm&language=en_US&type=5) |
| Refinement loop | Try variations of the template and get end-user feedback | [Best Practices](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_best_practices.htm&language=en_US&type=5) |
| Variability | Every run is a new LLM call, so the same prompt can return different responses | [Key Concepts](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_key_concepts.htm&language=en_US&type=5) |
| Repeated merge fields | Can lead to inconsistent results | [Troubleshoot Prompt Builder](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_troubleshoot.htm&language=en_US&type=5) |
| Template description | Shown in the Setup template list, not part of the prompt | [Create a Prompt Template](https://help.salesforce.com/s/articleView?id=ai.prompt_builder_build_template.htm&language=en_US&type=5) |

## Check yourself

- Why wrap directions in triple quotes under an `Instructions:` line?
- When is assigning a role with a goal a documented fix?
- Why can the same prompt return different text on two runs?
- Which two practices does Salesforce recommend for a team writing its first templates?
