Build useful prompts one layer at a time

Core idea: start small, strengthen deliberately

The RayAI framework has seven parts, introduced here in three layers. No earlier framework is required. Use the first layer for ordinary tasks and add the others when ambiguity, consequence, or repeatability increases.

Layer Parts What it solves
1. Start Task + Context + Output Makes the requested work and usable result clear.
2. Strengthen Audience + Boundaries Controls depth, tone, assumptions, exclusions, and missing information.
3. Trust Purpose + Quality check Connects the work to a human decision and defines how to handle evidence and uncertainty.

Layer 1 - Start

  • Task: What exact action should the model perform? Use a concrete verb: summarize, compare, draft, classify, extract, explain, critique, or propose.

  • Context: What facts or source material are necessary? Include only information that could change the answer.

  • Output: What form makes the result usable? Specify length, structure, fields, audience level, or tone only when they matter.

START TEMPLATE

Layer 2 - Strengthen

  • Audience: Who will use the result, and what do they already know?

  • Boundaries: What must the model not assume, disclose, include, or do? What should happen if a critical fact is missing?

Layer 3 - Trust

  • Purpose: What outcome or decision will this support? Who owns that decision?

  • Quality check: What should be verified, cited, labeled uncertain, recalculated, or escalated before use?

Fictional planning notes: An event for adult community members has a $600 budget ceiling. Maya offered to contact two possible speakers. The date and venue are not confirmed.

TRUST

Roles help with perspective, not authority

A role such as 'act as an editor' can guide vocabulary or perspective. It does not make the model a licensed professional, a policy owner, or an accountable decision-maker. Prefer a precise task and audience over grand titles such as 'world's best expert.'

Fix it

BLOATED PROMPT

Replace the hype and contradictions with a specific Task, relevant Context, usable Output, and one Quality check.

Try it: practice the skill

What to do

  1. Choose the task suggested for this module, or use another simple, low-risk task.
  2. Open ChatGPT or another AI assistant in a separate tab or window.
  3. For this module, rewrite your prompt using Task + Context + Output. Add only the details that make the answer more useful.
  4. Enter your prompt and send it. Do not include private or sensitive information.
  5. Read the AI answer.
  6. Return to this course and complete the short notes below.
    If you cannot use an AI assistant now, read the worked example and write what you would try later. Skip the steps that ask you to open, send or rerun a prompt. Label your notes "supplied example" or "planned test". Describe only what the example shows; if no output is supplied, write what you would look for. Keep checks you performed separate from checks you plan. Do not invent an AI result.
Path Your task
Everyday life Turn your baseline comparison into a clear Task + Context + Output prompt.
Learning Specify the learner level, topic boundaries, and how understanding will be checked.
Work Add audience, missing-information behavior, and a quality check to your fictional meeting task.

Module 2 test - check before you continue

Fast Track: answer Questions 1–3. Complete Course: answer Questions 1–4, writing a short response for Question 4. Then review the answer explanations for your path. Explain why your choice fits the situation, not just which letter you chose.

Your response stays in this page and is not saved or sent to RayAI.

1. You need a checklist from fictional event notes. Which starting prompt is most useful?
Review after attempting

Best answer: B. The useful start names the task, safe source context and output. A role or request for completeness does not define the necessary facts or deliverable.

2. Which instruction most directly addresses an invented deadline?
Review after attempting

Best answer: B. The instruction both prohibits invention and gives useful missing-value behavior. Tone and role do not control factual gaps.

3. What should you do when a critical input is missing?
Review after attempting

Best answer: B. If a missing input materially changes the result, the model should ask a concise question or state the gap rather than guess.

4. Rewrite your starting prompt. Include: (1) what you want the AI to do, (2) the facts it needs, and (3) what the answer should look like.

Review after attempting

Your revision should include one specific action, relevant facts or source material, and a usable output form. Extra parts are optional.
