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.

Match by input parameter v2.1.178

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:

```json .claude/settings.json {3} theme={null} { "permissions": { "deny": ["Agent(model:opus)"] } } ``` Match by input parameter

Set any setting from the prompt v2.1.181

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:

```text title="Claude Code" wrap theme={null} /config thinking=false ``` Commands reference

Other wins

Auto mode now blocks destructive git commands (`git reset --hard`, `git clean -fd`, `git stash drop`) when you didn't ask to discard local work, and blocks terraform destroy unless you asked for the specific stack

Set the new attribution.sessionUrl setting to false to omit the claude.ai session link from commits and PRs in web and Remote Control sessions

In the /config interface, Enter and Space both change the selected setting, and Esc now saves and closes instead of reverting

New sandbox.allowAppleEvents opt-in setting lets sandboxed commands send Apple Events on macOS

Point CLAUDE\_CLIENT\_PRESENCE\_FILE at a marker file to suppress mobile push notifications while you're at the machine

Long paragraphs now stream line by line instead of waiting for the first line break

API connection drops mid-thinking now retry automatically instead of showing "Connection closed while thinking"

With CLAUDE\_CODE\_EXPERIMENTAL\_AGENT\_TEAMS=1 set, every session has one implicit team, so you spawn teammates directly with the Agent tool's name parameter

Skills in nested .claude/skills directories load when working on files there; on a name clash the nested skill appears as `:` so both stay available

Fixed prompt caching not reading on a custom ANTHROPIC\_BASE\_URL and on Microsoft Foundry

Fixed Write and Edit producing zero-byte or truncated files on network drives and cloud-synced folders
