Looking for a Runway prompt for type narrowing? Start here — the high converting angle focuses on clarity, specificity, and measurable results. Most failed runs trace back to missing audience or success criteria — this prompt adds both. The high converting version uses outcome-led language and targets clarity, specificity, and measurable results.

When to use this prompt

Runway shines at code generation work when you state the observable outcome: make invalid hard. The High Converting framing keeps clarity, specificity, and measurable results visible while you edit. Pair it with a real sample from your portfolio for best results.

Why this prompt works

Separates draft from critique so you can steal the structure later.
Locks the audience (ts/python) before style so tone stays honest.
Repeats the hard constraint: examples.
Forces an output contract: headings, examples, and a final version.
The high converting angle adds clarity, specificity, and measurable results without extra fluff.

How to use it in Runway

Name the success metric aloud: make invalid hard. If the draft cannot pass it, do not polish prose yet. Paste the prompt into Runway and replace bracketed details with your facts. Generate two seeds or takes, then pick the clearer silhouette or motion. Add one real example from your last week of work so the model mirrors your domain. Functions, refactors, tests, and architecture sketches. Keep that context in the thread when you iterate.

Have Runway list assumptions about code generation before drafting. Delete any you cannot defend. 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 High Converting output. Runway models still need your facts for type narrowing; they cannot invent metrics or brand rules. developers teams bookmark slug type-narrowing-high-converting when clarity, specificity, and measurable results matters.

Step-by-step

Open Runway and paste the prompt block unchanged.
Replace placeholders with your project facts (ts/python, offer, timeline).
Confirm the constraint is still visible: examples.
Add a 100-word example before the second run if voice matters.
Reply with one fix list, then regenerate the final version only.

Example output

Example clip brief: 6s type narrowing shot, motivated light, single camera move, subject action matches "make invalid hard", no wardrobe changes mid-clip.

Common mistakes
