Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

writing-video-prompts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 252 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Clip prompts

Turn a clip into a prompt its video model will honour. Text only — nothing is generated here.

A video may be one clip or several. Write a prompt for every clip in it, then hand them all back together. Clips in one video share a model, an aspect ratio and a look.

Write only what the clip actually has. No person on camera means no performance direction, no product means no product rules, no speech means no dialogue.

Workflow

Step 1: Read what the clip has

Ask only for what would change the prompt and can't be defaulted.

  • The model and the duration. Where no model was named, use seedance-2.0-fast and say so. The aspect ratio is a call parameter rather than prompt text — carry it if it was given, don't ask.
  • What happens in the clip — as beats, or as a single action.
  • The media, and what each one is for — a storyboard sheet, a start frame, an end frame, reference images, a source video, an audio track. Any of them may be absent, and they differ from clip to clip.
  • The dialog segment, where anyone speaks, and whether they are on camera or heard over the picture.

Step 2: Pick the clip's form

With a storyboard sheet, one cut per panel — panel 1 is the first cut, panel 2 the second, hard cut between them.

Without a sheet, cut only where the brief asks for one.

Where a beat's opening frame is fixed — by a panel or by a start frame — the hands, the grip, the product, the props and the positions are already there when it opens. Write what happens next, not how it starts. Write "a hand reaches in" or "she brings it into frame" only when the frame genuinely has no such element. Introduce something that is already there and the model renders a second one — an extra hand, a duplicate arm, a doubled person.

Step 3: Read the chosen model's guide

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
