If you self-host Onyx, first configure the runtime described in Deploying Craft.
The deployment guide covers sandboxes, the proxy, workers, networking, storage, resources, and environment variables.
Control access
Open Admin Panel → Craft → Access.
For a limited rollout, turn off Enable Craft by default, then enable the users who should have access.
Per-user exceptions remain in place if you later change the workspace default.
Removing access prevents the user from starting new Craft work and skips future Scheduled Task runs they own.
It does not stop a turn already in progress or delete their sessions, files, Skills, Apps, or Scheduled Tasks.
Add workspace instructions
Open Admin Panel → Craft → Instructions to add guidance that every Craft agent in your workspace should follow. Onyx appends these instructions to Craft’s built-in instructions as an Organization instructions section. Good workspace instructions describe stable expectations that should apply to all Craft work:
For example:
Configure models
Craft supports Anthropic, OpenAI, and OpenRouter providers. Users also need access to the provider and at least one visible model. Give users provider access publicly or through a group. Agent whitelists apply to Onyx Agents, not Craft. See Language Model Access Controls for provider visibility settings.Anthropic
Configure an Anthropic provider and choose visible models.
OpenAI
Configure an OpenAI provider and choose visible models.
OpenRouter
Configure OpenRouter and select the models available through it.
Configure Apps and Skills
Apps
In Admin Panel → Craft → Apps, configure external services, credentials, and action policies.
Skills
In Craft → Skills, review reusable instructions and share custom Skills with users or groups.
Troubleshooting
The Craft section does not appear in the Admin Panel
The Craft section does not appear in the Admin Panel
Confirm you are signed in as an Admin. The section is hidden when Craft is unavailable on the deployment.
Self-hosted operators should review Deploying Craft.
A user has access but cannot start a session
A user has access but cannot start a session
Confirm the user can access an Anthropic, OpenAI, or OpenRouter provider with at least one visible model.
A provider limited only to an Agent whitelist is not available in Craft.
A user still has different access after the default changes
A user still has different access after the default changes
Check the user’s setting under Admin Panel → Craft → Access.
A per-user exception takes precedence over the workspace default until you change it.
Saved workspace instructions are not affecting a session
Saved workspace instructions are not affecting a session
Start a new session to test the saved instructions. They do not update an actively running session.
Also confirm the guidance does not conflict with Craft’s built-in hard rules or an enforced App policy.
Deployment
Configure the runtime required for self-hosted Craft.
Architecture
Review sandbox isolation, credential injection, approvals, and sharing boundaries.
