Drive Craft’s agent loop from a first prompt to a finished, shareable artifact
Craft is an AI co-worker that knows your company. Describe an outcome and it plans the work,
pulls context from your knowledge and connected tools, writes and runs code in a secure sandbox,
and keeps going until there’s a finished artifact to hand back. It’s a free-form agent loop,
like a coding agent such as Claude Code or Codex, pointed at almost anything your team builds: decks, reports,
dashboards, web apps, and documents.Each piece of work is a session: the chat and agent loop in the center, the Output panel (preview, files, artifacts)
on the right.
Build an all-hands slide deck on Q2. Pull the wins from Slack and Linear, use the numbers in the Q2 board
doc on Drive, and match our existing deck template.
In one unattended run, Craft reads those Slack channels, Linear issues, and the Drive doc through connected apps,
loads the pptx skill, and writes the deck, spawning subagents to build slides in parallel.The same loop builds a report: ask for a customer summary and Craft reads your HubSpot records,
cross-references Slack and Zendesk, and drafts it in your writing style, ready for you to review and refine.
Every session begins from the Craft home: pick a model, describe what you want,
and connect the data sources Craft should draw on.Pick a model first if your workspace offers more than one. The model is locked once the session has messages,
so choose before you send.Craft does its best work when the first prompt covers:
The artifact: a web app, report, deck, brief, data explorer, or export file.
Audience and purpose: who it is for and what they need from it.
Source material: Onyx knowledge, attached files, User Library files, or a connected app.
The requirements that matter: sections, tone, charts, filters, tables, file names, or output format.
Craft rarely stops to ask clarifying questions. It makes reasonable assumptions and keeps moving,
so front-load the details you care about and refine from there.
As Craft runs, the chat panel streams the loop in real time:
Tasks: the plan Craft is working through, checked off as it goes.
Thinking: how it is reasoning about the next step.
Working: tool calls, such as searching company knowledge or reading a file in a connected app.
Running: shell commands in the sandbox, like writing code, installing packages, or starting a dev server.
Subagents: for larger jobs, Craft spawns focused subagents (for example, one per slide or per section)
and runs them in parallel. Open a subagent from the header dropdown to read its transcript;
your replies still go to the main session.
A status indicator in the header shows the sandbox state, such as Initializing sandbox, Sandbox running,
or Restoring sandbox.You stay in control while it works:
Queue a follow-up: send another message during a run and Craft picks it up after the current turn.
Interrupt: press Esc to stop a run heading the wrong way. Your messages and files are kept,
so you can redirect and continue.
Craft starts from your prompt, but most real work needs source material. Use the + button (Add files or skills)
or type / to add context, and combine as many sources as you need in one session.
Source
Use it for
Onyx knowledge
Company documents and connector data you already have permission to access.
Session attachments
Files that only matter for this session, like a CSV, PDF, notes doc, or image.
User Library
Reusable files you want across sessions, like templates or datasets.
Skills
A method or capability, such as building a deck or searching company knowledge.
Apps
External services such as Slack, Google Drive, Gmail, Linear, or GitHub.
Session attachments stay with one session. User Library files are durable and reusable across sessions.
You can also drag and drop files onto the chat.

The User Library accepts regular files and zip uploads. Zips are extracted so Craft can work with the files inside.
Don’t upload secrets, private tokens, or production credentials as files. To let Craft reach an external service,
connect it as an app instead.
Credentials are injected securely and never stored in the sandbox.
A live, running web app. Ask for changes and the preview updates as the files change.
Files
The full session workspace: source code, data, and intermediate work.
Artifacts
Finished outputs meant for download or sharing, usually written to outputs/.
From here you can download a single file, or a directory or web app as a zip, export a Markdown file to .docx,
and preview images, PDFs, presentations, and text files.
