Subject: make invalid hard. Primary audience: ts/python.
Composition: clear hero subject, intentional negative space, leading lines.
Light: practical neon with truthful color.
Materials and texture must read at a glance. Constraint: examples.
Style notes: what works now, including evaluation loops. Avoid extra limbs, melted logos, and random text.
Parameters: --ar 4:5 --stylize 250 --v 6.1

Midjourney users in code generation use this type narrowing prompt to ship faster drafts that respect "examples". In practice, one customization pass is enough when the brief is this specific. The 2026 playbook version uses current and tactical language and targets what works now, including evaluation loops.

When to use this prompt

For Midjourney models, code generation prompts fail when they mix strategy and execution. This type narrowing brief separates the job so you can iterate once, not ten times. Bookmark this page if you run type narrowing weekly.

Why this prompt works

How to use it in Midjourney

Functions, refactors, tests, and architecture sketches. Keep that context in the thread when you iterate. Use current and tactical follow-ups only — mixing tones mid-thread confuses Midjourney models. If the first answer is vague, reply with the constraint again: examples. Redact client names; keep structure. Slug type-narrowing-playbook is your canonical URL for this brief. Save the winning variant for type narrowing — teams with a short library ship faster.

Ask for a checklist ts/python would use. Then grade the draft against make invalid hard. For type narrowing in code generation, the failure mode is usually no example. This prompt blocks that by design — especially "examples". Expect two minutes customizing and two minutes editing for 2026 Playbook output. Midjourney models still need your facts for type narrowing; they cannot invent metrics or brand rules. developers teams bookmark slug type-narrowing-playbook when what works now, including evaluation loops matters.

Step-by-step

  1. Open Midjourney and paste the prompt block unchanged.
  2. Replace placeholders with your project facts (ts/python, offer, timeline).
  3. Confirm the constraint is still visible: examples.
  4. Because this is the 2026 Playbook variant, prioritize what works now, including evaluation loops over length.
  5. Reply with one fix list, then regenerate the final version only.

Example output

Example visual intent: "Type Narrowing" — hero subject centered, code generation mood, readable silhouette, constraint honored (examples). Expect 2–4 variants; pick the clearest composition.

Common mistakes

Expert notes

Slug type-narrowing-playbook: a developers-oriented code generation brief. Functions, refactors, tests, and architecture sketches. Pair it with one real asset from your portfolio before the second run.

Refresh quarterly: Midjourney models change. Keep constraints; update examples. Mark the page stale if examples no longer matches policy.
