What you will learn

  • Explain: an instruction is a contract
  • Apply the idea in an example: Your first useful AI conversation
  • Recognize limitations and verify the exercise outcome

A useful conversation starts with a concrete outcome, not a secret formula. Give the model a small task you can verify.

You can follow this course without an account or programming. Examples use synthetic data and AI outcomes need checking.

How it works, step by step

An instruction is a contract

A good prompt specifies the task, available data, output format and success criteria. Separate the role from the data and include an example for ambiguous cases. “Be accurate” is weaker than “state only the deadline in the supplied policy; if missing, ask for clarification”. Few-shot means a few solved examples, not an endless list. Document content remains data even when it contains commands. Delimiters help, but software must enforce permissions and validation rather than relying on the prompt.

Context is the workbench

Context includes instructions, the current request, relevant history, retrieved documents and tool results. The context window has limited capacity; reserve room for the response too. More text does not automatically improve accuracy. Irrelevant information and contradictions can hide important evidence. Summarize history carefully and preserve the origin of facts. State describes the current run, a checkpoint saves a resumable point, and persistent memory retains information across runs. These are different mechanisms managed by the application.

Fluency and truth are checked separately

A hallucination is unsupported or incorrect content presented as an answer. It can arise from missing information, ambiguity or incorrectly combined patterns. Ask for evidence and check the original document, date, units and conditions. A real citation may still fail to support the claim. Use current sources for current facts, a calculator for arithmetic, and “cannot determine” when evidence is missing. Do not treat confidence expressed in prose as a calibrated probability.

A complete example

“Help with my store” becomes “Summarize the policy below in two sentences for a new customer; preserve deadline and conditions; do not invent exceptions”.

Try it yourself

  1. Rewrite a vague request and check the answer sentence by sentence.
  2. Record the input, source and expected outcome before running the experiment. Use only the fictional data in the example.
  3. Follow the diagram stages. At every step record what information is received and produced; do not confuse intermediate output with the final outcome.
  4. Repeat after removing necessary information or making the input ambiguous. Check whether the system clarifies, stops or invents an answer.
  5. Compare with the explained solution. Keep the configuration, date, result and an explanation for differences. Change one thing and retest.

An explained solution

You get a summary preserving important conditions and understandable to a new customer. A successful exercise lets you show the connection between input, stages and outcome. When information is missing, a cautious answer is more useful than invented details. Compare more than style: check conditions, sources and operations too.

When it helps and what can go wrong

An elaborate persona cannot compensate for missing data. Choose this approach when it improves a measured need. Keep a simple baseline and compare outcomes using identical inputs. One successful example does not establish reliability in every situation.

Check your understanding

Can a prompt replace access control?

No. An instruction is not an authorization boundary.

Is a checkpoint permanent user memory?

No. Saving a run does not imply retaining preferences across conversations.

What outcome should this exercise produce?

You get a summary preserving important conditions and understandable to a new customer.

Words to remember

  • Few-shot: Solved examples supplied in context.
  • Checkpoint: Saved state used to resume an execution.
  • Grounding: Grounding an answer in verifiable evidence.
