Pair inputs with outputs
Two representative input-output pairs establish the normal transformation more clearly than disconnected examples.
FEW-SHOT PROMPT PLANNER
Example-Driven Prompt Builder
Plan a balanced set of representative inputs, expected outputs, edge cases, and counterexamples for a more testable coding prompt.
- Uses your inputs in a transparent calculation

YOUR INPUTS
Build your result
Complete every field. The result updates only when you choose Calculate.
How it works
Add boundaries and counterexamples
At least one edge case and one forbidden output reveal where the rule stops.
Score the example pack
Capped points reward balanced coverage and output-format clarity without encouraging a bloated prompt.

Frequently asked questions
How many examples should a coding prompt include?
Start with the smallest diverse set that demonstrates normal, boundary, and forbidden behaviour. Add more only when they resolve a real ambiguity.
What is a counterexample?
It is a plausible input or output that must not be accepted, often paired with the rule it violates or the required error behaviour.
Can examples replace acceptance criteria?
No. Examples clarify instances; acceptance criteria state the general rules that every valid implementation must satisfy.
