Keeps code generation vocabulary specific instead of buzzwords.

How to use it in Midjourney

Save the winning variant for pure function — teams with a short library ship faster. If the first answer is vague, reply with the constraint again: types + tests. This 2026 Playbook path is for engineers who care about small testable unit. When engineers review output, they should see what works now, including evaluation loops without hunting for it. Redact client names; keep structure. Slug pure-function-playbook is your canonical URL for this brief.

Open Midjourney and paste the prompt block unchanged.
Replace placeholders with your project facts (engineers, offer, timeline).
Confirm the constraint is still visible: types + tests.
Because this is the 2026 Playbook variant, prioritize what works now, including evaluation loops over length.
Reply with one fix list, then regenerate the final version only.

Example output

Example visual intent: "Pure Function" — hero subject centered, code generation mood, readable silhouette, constraint honored (types + tests). Expect 2–4 variants; pick the clearest composition.
