The three agents

In short

• Three Claude agents do the writing, each in the place you need it
• The PROMPT AGENT turns a rough description into a prompt written for the model you picked. Launch it from the Studio (The Prompt Agent)
• The BRIEF AGENT interviews you and fills your brief’s blocks. Launch it from any project’s Brief page (The Brief Agent)
• The SKILL WIZARD turns the way you work into a Skill you can reuse, in five steps (The Skill wizard)
• All three propose and wait. Nothing is saved, generated or spent until you say so (The rule all three follow)
• Each Prompt Agent send costs credits, and the price is shown before it answers

The rule all three follow

They ask before they act. Every one of them proposes (a prompt, a block, a step), and nothing is generated or saved until you accept it. Nothing is charged to your credits without its price shown before you press. An agent that spends your money on its own judgment is not a feature we want, however good the judgment.

This is also why they ask questions. An agent that guesses silently is faster right up until the moment it guesses wrong, and then it is much slower.

The Prompt Agent

Describe the shot. It asks what matters.

The Prompt Agent works in two modes. This section is the Studio conversation, where you talk to it about one prompt. The other is shot composition, where it writes a prompt from each shot-list row on its own and asks you nothing; see How a prompt is assembled from a shot.

You write what you want in plain language and it composes the Key Prompt (lighting, lens, framing, grade) in the vocabulary the model you have chosen actually responds to. Where your description leaves something open that will change the picture, it asks rather than deciding for you.

It reads the brief attached to your project, so the cast, the locations, the props and the look are already in its head. That is the difference between a prompt that reads well and a prompt that produces the picture you meant.

It is the tool for changing one prompt. Open it in the Studio and it works on the prompt in front of you: tighten a line, work in a reference you have just attached, change the framing, cut a length. It proposes the edit into the composer and you save it, or do not.

That is the difference between it and recomposing, which is the other way to change a prompt’s text. Recompose rebuilds the whole prompt from the brief and the shot row and replaces what is there, including anything you wrote yourself. The Prompt Agent changes the words that are already there. When the change is to one prompt, it is the right instrument.

It will refactor a prompt to a model’s limit. Every model has a hard prompt limit and they differ by more than tenfold, so a prompt composed for a generous default can be refused by a tighter model purely on length. Ask the agent to fit it and it will. And it is told the room it actually has, not the raw limit: Lorvara appends the reference tokens and the order line on the way out, and that is measured and taken off before the agent is given a budget. It is also told how long the prompt in the composer already is, in the same unit, so it shortens by a measured amount rather than an estimate.

A turn costs credits, and the panel says so: each send costs 8 credits from the balance this project spends. The price is on the send button before you press it.

A turn can take as long as it needs. Turns run as background work rather than inside the request that asked for one, and the answer streams back as it accumulates. A long turn is a long turn, not a turn that dies at sixty seconds with nothing to show for it.

If a turn produces no answer, you are told about the money. The agent says “The agent didn’t finish, and no credits were charged.” Credits are reserved when the turn starts and only charged against an answer; anything else releases the reservation.

The Brief Agent

Bring a brief, or build one block by block.

If you already have a treatment, a deck or a document, paste it and the Brief Agent parses it into blocks: intent, cast, props, location, glossary, look. If you do not, it builds them with you one at a time.

Nothing composes while a block is still a draft, and guesses stay marked as guesses until you touch them. You can argue with every line it writes.

The Skill wizard

Five guided steps to a skill of your own.

A Skill is how a format actually fails, written down: the composition rules, the constraints, the questions worth asking, the mistakes that kind of shot makes. The wizard turns the way you already work into one, in five steps, so the Prompt Agent applies it every time instead of you remembering to.

You can also write a Skill by hand or import one someone else wrote. See Writing your own and Importing.
