Practice Challenges

See the available challenge tracks, what they teach, and what is required before you run them.

Explorer: Make It Clear

Get comfortable with the Canvas — run a prompt, see the output, make a change, run again.

Concept: The Canvas lets you prototype instructions visually: connect a Prompt node to an LLM and read the output.

Explorer: Build a Better Prompt

Turn a vague topic into a clear instruction by specifying task, audience, and format.

Concept: A better prompt makes the job more explicit instead of leaving important decisions to the model.

Explorer: Templates & Inputs

See how a template prompt works with runtime inputs from the Input node.

Concept: A prompt with {{}} slots can produce different outputs for different inputs without editing the instruction.

Explorer: Make It Remember

Fix a prompt by adding missing context so the model can answer correctly.

Concept: The model does not remember previous information unless you include it in the prompt.

Explorer: Why Specificity Matters

Improve a weak prompt using the 3-rule checklist: clarity, scope, and constraints.

Concept: Structure alone is not enough. The prompt must be specific about what, who, and how.

Explorer: Understanding LLMs

Understand what the LLM node does and how its settings affect the output.

Concept: The LLM node executes the prompt. Its model and temperature settings are part of the instruction system.

Explorer: Remove the Vague Words

Replace vague wording with clear, measurable instructions.

Concept: The model performs better when instructions are specific and quantifiable.

Explorer: Force the Shape

Improve a prompt by explicitly defining the output format.

Concept: When you ask for a specific format, the output becomes easier to control and more useful.

Explorer: Role Assignment

See how assigning a role to the model changes the output dramatically.

Concept: Telling the model who it is and who it's talking to shapes perspective, depth, and tone.

Instructor: Using Delimiters

See how adding delimiters changes the model's ability to distinguish data from instructions.

Concept: Delimiters like ---TEXT--- / ---END--- tell the model where instructions end and data begins.

Instructor: Negative Constraints

See how NEVER rules strip fluff and produce exactly what you asked for.

Concept: Negative constraints (NEVER, AVOID, DO NOT) block the model's default conversational behavior.
