Context, Information Boundaries, and Audience

2. Learning Outcomes

By the end of this lesson, you should be able to:

1. Identify the minimum context required for a given AI-supported task.
2. Distinguish necessary from unnecessary, irrelevant, sensitive, or unsupported contextual details.
3. Apply preliminary information classification and minimization to a prompt.
4. Classify information provisionally as public, internal, personal, confidential, proprietary, privileged, security-sensitive, or culturally governed.
5. Define an intended audience with attention to prior knowledge, terminology, language, tone, purpose, accessibility, and disciplinary context.
6. Adapt a prompt for two different audiences while preserving the same underlying purpose.
7. Explain why "general audience" is often too vague and why assuming a default user is problematic.
8. Construct a prompt that includes necessary context, minimizes extraneous information, and addresses a defined audience.

3. Before You Begin

• Assigned reading: Chapter 4: Prompt Design Fundamentals (sections on Context and Audience).
• Required prior knowledge: Lesson 4.1 (Purpose and Task Definition); understanding of the distinction between purpose, task, output, use, and action; basic awareness of information privacy and confidentiality.
• Optional AI tool: You may use an institutionally approved generative AI system for guided activities. Supplied outputs are provided if you do not have access.
• Privacy reminder: Do not enter personal, confidential, proprietary, or culturally governed information into any AI system unless it is explicitly approved for that purpose.
• Academic integrity: All work you submit must be your own. Document any AI use transparently.
• Estimated preparation time: 15–20 minutes to review Chapter 4 and Lesson 4.1.

4. Retrieval Practice: Concepts from Lesson 4.1

Before we add context and audience, let's refresh the key ideas from Lesson 4.1.

5. Opening Scenario: "The Over-Detailed Prompt"

6. What Is Context?

In the PCAFE-V framework, Context is the information, constraints, background, sources, definitions, and boundaries that the AI system requires to support the task effectively.

Context answers questions like:

• What background information is essential?
• What definitions or terminology should be used?
• What date, location, jurisdiction, discipline, or version matters?
• What are the constraints or limitations?
• What assumptions should be stated explicitly?

More context is not automatically better

A common misconception is that providing more context always improves the output. In reality, excessive context can:

• Introduce irrelevant or misleading information;
• Overwhelm the AI's context window;
• Increase the risk of exposing sensitive information;
• Make the output more difficult to evaluate;
• Distract the AI from the core task.

The goal is minimum necessary context: enough information to support the task, but no more. Context should be:

• Relevant: Directly supports the task and purpose;
• Sufficient: Provides everything needed, nothing more;
• Authorized: You have permission to share it;
• Accurate: Correct and up to date;
• Labelled: Clear source and status;
• Minimized: Stripped of unnecessary details.

7. Information Boundaries

Not all information should be included in a prompt. Some information is sensitive, confidential, or protected. Before you include any information in a prompt, you should consider its classification and whether you are authorized to share it with an AI system.

At an introductory level, information can be classified into these categories:

8. What Is Audience?

In the PCAFE-V framework, Audience is the intended reader, user, learner, reviewer, participant, or stakeholder for whom the output is being prepared.

Audience is not just about who will read the output; it is about how they will use it and what they need to understand.

Avoiding the default audience trap

Many prompts assume a "default" audience that is often:

• Technologically experienced;
• Highly literate;
• Able-bodied;
• English-first;
• Employed;
• Familiar with North American systems;
• Authorized to act.

These assumptions are problematic because they exclude or disadvantage people who do not fit this profile. A responsible prompt designer actively considers the actual audience and adapts the output accordingly.

When defining an audience, consider:

• Prior knowledge: What does the audience already know?
• Purpose: Why are they reading this? What will they do with it?
• Language: What language(s) do they use? What level of formality?
• Terminology: What terms need to be defined? What jargon should be avoided?
• Reading level: Is the text appropriate for the audience's literacy level?
• Cultural context: Are there cultural considerations or sensitivities?
• Accessibility: Does the format support diverse needs (e.g., screen readers, plain language, colour contrast)?
• Tone: Is the tone appropriate for the relationship and context?
• Expected action: What should the audience do after reading?

9. PCAFE-V Walkthrough: Context (C)

Guiding questions for context

• What information is essential for the AI to complete the task?
• What information is irrelevant, outdated, or distracting?
• Is the information accurate and authorized for sharing?
• What assumptions should be stated explicitly?
• Which terminology or definitions must be used?
• Which date, location, jurisdiction, discipline, or version matters?
• What information must not be supplied?
• What should the AI do when context is missing?

Weak vs. improved context

Write a briefing on our tutoring program. We are Bright Futures, a nonprofit in Toronto. We have been around for 12 years. The program costs $50,000. Make it professional.

Write a one-page briefing on a community after-school tutoring program for an internal review committee.

Background: The program serves 200 students annually and is funded by a foundation grant.

Definitions: "Tutoring program" means one-on-one academic support in literacy and numeracy for grades 3-6.

Constraints: The briefing must be concise (under 500 words) and focus on program outcomes, not administrative details.

Do not include: Specific financial figures, staff names, or location details.

If information is missing, indicate what is needed and do not invent.

Common mistakes

• Including unnecessary personal or organizational details: Names, addresses, exact costs, and staff details are often irrelevant to the AI's task.
• Providing context that is too vague: "Make it professional" is not context; it is a vague quality instruction.
• Assuming the AI knows the context: The AI does not know your organization's history, culture, or policies unless you tell it.
• Not telling the AI what to do when context is missing: Without guidance, the AI may invent details or proceed with flawed assumptions.

Responsible-use consideration

Minimizing context reduces the risk of exposing sensitive information. It also helps you think critically about what the AI actually needs to know. A prompt with too much context is often a sign that the human has not clearly defined the task.

Brief practice: context minimization

Identify the unnecessary details in this prompt:

"I am a marketing manager at XYZ Corp, which is located at 456 Oak Street, Vancouver. Our CEO is Michael Brown, and we have 50 employees. I need a draft email to send to our customers about our new product. The product is a software tool for project management. Our customers are small business owners. We launched the company in 2015. Please write a friendly but professional email."

10. PCAFE-V Walkthrough: Audience (A)

Guiding questions for audience

• Who is the intended reader or user of the output?
• What is their prior knowledge of the topic?
• What is their purpose for reading or using the output?
• What language(s) do they use? What is their preferred reading level?
• What terminology do they understand? What needs to be defined?
• Are there cultural considerations or sensitivities?
• What accessibility needs should be addressed?
• What tone is appropriate for the audience and context?
• What action should the audience take after engaging with the output?

Weak vs. improved audience

One purpose, two audiences

A single purpose may require different outputs for different audiences. For example, a briefing on a new policy might be written for:

• Executive committee: Focus on strategic implications, risks, and costs.
• Frontline staff: Focus on practical implementation, day-to-day changes, and what they need to do.
• Public: Focus on benefits, plain-language explanations, and how the policy affects them.

When adapting a prompt for different audiences, consider changes to:

• Tone: Formal vs. informal; authoritative vs. collaborative.
• Terminology: Technical vs. plain language; definitions provided or assumed.
• Depth: High-level overview vs. detailed analysis.
• Structure: Executive summary first vs. background first.
• Action orientation: What should the audience do differently?

Common mistakes

• Assuming a "default" audience: Assuming the audience is technologically experienced, literate, English-first, and able-bodied.
• Not defining the audience at all: Writing as if the AI knows who it is writing for.
• Conflating audience with purpose: The audience is who; the purpose is why.
• Ignoring accessibility: Not considering readers who use screen readers, have low vision, or have cognitive disabilities.

Responsible-use consideration

Defining the audience explicitly helps ensure the output is usable and equitable. It also makes it easier to evaluate whether the output meets the audience's needs and whether any adjustments are needed for accessibility, language, or cultural context.

Brief practice: audience adaptation

Adapt the following prompt for two audiences:

"Explain how blockchain technology works."

Audience A: A group of high school students with no technical background.

Audience B: A team of software engineers who are familiar with distributed systems but new to blockchain.

11. Worked Example: From Over-Detailed to Minimal Context with Defined Audience

Let's revisit the opening scenario and transform the over-detailed prompt into a well-structured prompt with minimized context and a defined audience.

Write a briefing on our new after-school tutoring program. We are a nonprofit called "Bright Futures" located at 123 Main Street, Toronto. Our executive director is Jane Smith, and we have been operating for 12 years. We serve 200 students annually. This program is funded by the Atkinson Foundation. The committee includes my boss, Sarah, and three other directors. The program costs $50,000. Please make it professional. The committee likes concise reports.

Step 1: Identify necessary context

• Type of program: After-school tutoring.
• Purpose: Internal review briefing.
• Format: One-page, concise.
• Audience: Internal committee.

Step 2: Remove unnecessary and sensitive details

• Remove: Organization name, address, executive director name, number of years, committee names, exact cost.
• Generalize: "A local nonprofit," "our organization," "a foundation grant."
• Keep: Program type, audience (internal committee), need for concision.

Step 3: Define the audience

• Who: Internal review committee members.
• Prior knowledge: Familiar with the organization but not necessarily the details of the program.
• Purpose: To assess the program's outcomes and decide on continued funding.
• Needs: Clear, concise, evidence-based information focused on results.

Step 4: Write the improved prompt

Purpose: Help me prepare a one-page briefing on a community after-school tutoring program for an internal review committee.

Context: The program serves 200 students annually and is funded by a foundation grant. The focus should be on program outcomes and impact, not administrative details.

Definitions: "Tutoring program" means one-on-one academic support in literacy and numeracy for grades 3-6.

Constraints: Keep the briefing under 500 words. Use a concise, professional tone.

Exclusions: Do not include specific financial figures, staff names, or location details. Do not reference internal organizational history.

Missing information: If key information is missing (e.g., outcome data, participant feedback), indicate what is needed and do not invent.

Audience: Internal review committee members who are familiar with the organization but need clear, evidence-based information to make a funding decision. They value concision and clarity. Use plain language and avoid unnecessary jargon.

Step 5: Identify remaining questions

• What specific outcome data is available?
• What is the committee's preferred format for briefing notes?
• What is the deadline?
• Are there any specific evaluation criteria the committee uses?

19. Key Takeaways

• Context is essential but must be minimized. Provide only what the AI needs; remove unnecessary, sensitive, or irrelevant details.
• More context is not automatically better. Excessive context can introduce noise, increase risk, and overwhelm the AI.
• Classify information before sharing. Consider whether information is public, internal, personal, confidential, proprietary, privileged, security-sensitive, or culturally governed. When in doubt, do not share it.
• Define your audience explicitly. Avoid "general audience." Specify prior knowledge, language, terminology, tone, accessibility, and purpose.
• Adapt prompts for different audiences. The same purpose may require different outputs for different groups.
• Assume nothing about a default user. Do not assume your audience is technologically experienced, literate, English-first, or able-bodied.
• Accessibility is a core consideration. Ensure outputs are usable by people with diverse needs, including those using screen readers or with low vision.
• Context and audience work together. The context you provide and the audience you define shape the output's relevance, clarity, and usability.

21. Looking Ahead: Lesson 4.3

In Lesson 4.1, you defined a legitimate human purpose. In Lesson 4.2, you added context and audience. In Lesson 4.3, you will add the next two PCAFE-V elements:

• Format: What output form best supports the human purpose and audience? How should the output be structured, organized, and presented?
• Evaluation Criteria: What observable qualities define a good output? How can you replace vague instructions like "make it professional" with specific, reviewable criteria?

By the end of Lesson 4.3, you will have a prompt that specifies purpose, context, audience, format, and evaluation criteria. The final element, Verification Requirements, will be added in Lesson 4.4.

Transition to Unit 5: After completing Unit 4, you will move to Unit 5: Advanced Prompting and Context Engineering, where you will extend individual prompts into multi-stage workflows, handle context drift, and apply the SCOPE framework.
