Agent Chat Stream

Everything below can be changed without touching the animation. Hand the list to an agent, or edit the values at the bottom of the component file.

• Prompt *

  prompt · string

  The user's message, shown as a chip at the top right of the transcript. One sentence, the answer is the subject here, not the question.

  now: Turn the launch notes into a 30-second film.

• Answer *

  answer · string

  The assistant's first reply, revealed word by word before the tools run. 20–30 words is the sweet spot for the 8s budget; longer is streamed faster to fit.

  now: Reading the notes now. I'll pull the headline, three feat…

• Reply *

  reply · string

  The closing reply, revealed after the last call resolves. This is the line that sits on the held frame, so make it the payoff, 12–18 words.

  now: Six scenes, twenty-nine point eight seconds. Preview is r…

• Tools

  tools · array

  Tool-call chips, appearing between the two replies and overlapping by half a second. Two is the honest number for an 8s scene; three is the ceiling and squeezes the prose.

  now: 2 items

• Agent

  agent · string

  Name in the header, beside the accent mark. A product name works better here than a model name.

  now: Assistant

• Model

  model · string

  Mono model tag in the metadata rail. Empty string drops the row.

  now: registry-1

• Pace

  pace · number

  Streaming speed multiplier. 1 is ~13 words a second, which is what a fast stream looks like; 0.7 reads more deliberate. Long copy is sped up automatically to make the budget regardless.

  now: 1

• Rail

  rail · boolean

  Show the metadata rail, model, token count, tool progress, elapsed clock. Ignored on portrait and square frames, where the transcript takes the full width instead.

  now: true

• Seed

  seed · string

  Seeds the per-word jitter that keeps the stream off the metronome. Change it for a differently-paced take of identical duration; the same seed always renders identical frames.

  now: stream-01

• Brand

  brand · string

  Brand token id, one of the keys of BRANDS.

  now: slate
