Artifacts

An artifact is a live, interactive page that Claude Code publishes from your session to a private URL on claude.ai, and it updates in place as the session keeps working. Ask for one when terminal text is the wrong medium, such as a PR walkthrough with the diff annotated inline or a dashboard built from session data. Artifacts are in beta on Team and Enterprise plans.

Ask Claude for a page, then approve the publish prompt:

Make an artifact that walks through this PR with the diff annotated inline.

Match by input parameterv2.1.178

Deny and ask permission rules can now match a tool's input parameters with the Tool(param:value) syntax. For example, Agent(model:opus) matches subagent spawns that request the Opus model tier. The value accepts `*` as a wildcard, so `Agent(isolation:*)` matches any explicit isolation value.

Add a parameter rule to the deny list in settings.json:

{
  "permissions": {
    "deny": ["Agent(model:opus)"]
  }
}

Match by input parameter

Set any setting from the promptv2.1.181

Pass key=value to /config to change a setting directly without opening the Settings interface. The syntax also works in non-interactive mode with the -p flag and from Remote Control.

Set the thinking setting from the prompt:

/config thinking=false
