44Unless you name a location, Claude writes the page to an HTML or Markdown file in a temporary directory outside your project, then publishes it. Outside [plan mode](/docs/en/permission-modes#analyze-before-you-edit-with-plan-mode), a new artifact that Claude publishes in response to a prompt you type goes through without a permission prompt or classifier review, unless that publish declares runtime capabilities for the page, such as [connector calls](#pull-live-data-with-mcp-connectors) or [file downloads](#offer-a-file-download). In plan mode, Claude Code asks you before the first publish of each artifact.

46The artifact stays private to you until you [share it](#share-an-artifact). After you share it publicly, Claude Code asks for your approval once per conversation before changing it, or in [auto mode](/docs/en/permission-modes#eliminate-prompts-with-auto-mode) has the classifier review the change.
46After the first publish, Claude prints the URL, and your browser opens to the new page.

48If you turned [feature-flag fetching](/docs/en/env-vars#features-that-need-feature-flag-fetching) off, Claude Code asks before the first publish of each artifact, or in auto mode has the classifier review it.
48* **Reopen the page**: press `Ctrl+]` at any time to reopen the session's most recent artifact
49* **See this session's artifacts**: a `⧉` pill below the prompt shows the artifact's name, or a count when the session has several. In [fullscreen rendering](/docs/en/fullscreen), click it to open the [`/artifacts`](#find-an-artifact-again) list
50* **Keep the browser from opening**: set `CLAUDE_CODE_ARTIFACT_AUTO_OPEN=0` in your environment
51* **Remote Control**: if you sent the prompt through [Remote Control](/docs/en/remote-control) from claude.ai, Claude Desktop, or the Claude mobile app, no tab opens on the machine running the session. The browser opens there the next time Claude publishes the artifact from a prompt you type at the terminal

50After the first publish, Claude prints the URL, and your browser opens to the new page. If you sent the prompt through [Remote Control](/docs/en/remote-control) from claude.ai, Claude Desktop, or the Claude mobile app, no tab opens on the machine running the session. The browser opens there the next time Claude publishes the artifact from a prompt you type at the terminal. Press `Ctrl+]` at any time to reopen the session's most recent artifact.
53Claude picks the artifact's title and a browser-tab icon that matches what the page is, such as a chart or a calendar. The title appears in your [gallery of artifacts](#share-an-artifact) on claude.ai and in shared links. Ask Claude for a specific title or tab icon if you want one.

52Claude picks the artifact's title and an emoji, and both appear in your [gallery of artifacts](#share-an-artifact) on claude.ai and in shared links. Claude can also pick a browser-tab icon that matches what the page is, such as a chart or a calendar. Ask Claude for a specific title, emoji, or tab icon if you want one.
55If Claude responds that it can't publish, or writes a local HTML file without a link, artifacts aren't enabled for your session. Check the [Availability](#availability) requirements. If the terminal shows `Artifacts need a claude.ai login`, see [that error's entry](/docs/en/errors#artifacts-need-a-claude-ai-login) for how to sign in.

54To stop the browser from opening automatically when a new artifact is published, set `CLAUDE_CODE_ARTIFACT_AUTO_OPEN=0` in your environment.
57### When Claude Code asks before publishing

56If Claude responds that it cannot publish, or writes a local HTML file without a link, the tool is not enabled for your session. Check the [Availability](#availability) requirements.
59A new artifact that Claude publishes in response to a prompt you type goes through without a permission prompt or classifier review. In these cases Claude Code asks you first, or in [auto mode](/docs/en/permission-modes#eliminate-prompts-with-auto-mode) has the classifier review the publish:
5760
61| When | What Claude Code does |
62| :- | :- |
63| The session is in [plan mode](/docs/en/permission-modes#analyze-before-you-edit-with-plan-mode) | Asks before the first publish of each artifact |
64| The publish declares runtime capabilities for the page, such as [connector calls](#pull-live-data-with-mcp-connectors) or [file downloads](#offer-a-file-download) | Asks before that publish |
65| You shared the artifact publicly | Asks once per conversation before changing it |
66| You turned [feature-flag fetching](/docs/en/env-vars#features-that-need-feature-flag-fetching) off | Asks before the first publish of each artifact |
67| Claude publishes in a turn that a [scheduled task](/docs/en/scheduled-tasks) firing in your session started, rather than a prompt you typed | Asks before the first publish of each artifact |
68| Claude can't read the file without your approval | Asks before publishing it. An allow rule for the `Artifact` tool doesn't skip this prompt |
69
70Claude reads files in your session's [working directories](/docs/en/permissions#working-directories), and in the temporary directory it writes pages to, without asking. To let Claude publish from another folder without the prompt, add the folder as a working directory with [`--add-dir`](/docs/en/cli-reference#cli-flags) at launch or `/add-dir` during the session.
71
5872## Update an artifact

6074Ask Claude to revise the page, or let a long-running task republish as it makes progress. Claude edits the underlying file and publishes again to the same URL.

7488## Find an artifact again
7589
76Run `/artifacts` in Claude Code to list every artifact you own and every artifact shared with you. Select one and press `o` to open it in your browser or `c` to copy its link. Press `Enter` to attach it to the current session; before v2.1.216, `Enter` opened it in your browser. Claude Code reads the list from your claude.ai account, so it works in a new session and after `/clear`, when the link has scrolled out of the terminal. Requires Claude Code v2.1.208 or later.
90Run `/artifacts` in Claude Code to list the artifacts you own and the ones shared with you. The current session's artifacts come first, under **This session**. Requires Claude Code v2.1.208 or later.
7791
92Select an artifact, then press one of these keys:
93
94* **`Enter`**: opens it in your browser when it's already attached to the current session, and attaches it when it isn't. Before v2.1.216, `Enter` opened it in your browser
95* **`o`**: opens it in your browser
96* **`c`**: copies its link
97
98Claude Code reads the list from your claude.ai account, so it works in a new session and after `/clear`, when the link has scrolled out of the terminal.

78100## Share an artifact
79101
80102A new artifact is visible only to you. To share it, open the artifact in your browser and use the **Share** control in the page header. The header also links to your gallery at [claude.ai/code/artifacts](https://claude.ai/code/artifacts), which lists every artifact you have created.
from line 114
92114
93115An editor publishes new versions the same way you [update the artifact from another session](#update-an-artifact): they give Claude the artifact's URL, or attach it from [`/artifacts`](#find-an-artifact-again), and Claude pulls the current content and republishes with their changes. Everyone with the page open sees each update live.
94116
117If an editor publishes while Claude holds an older copy of the page, Claude Code refuses a publish built on that copy. Claude then merges its changes onto the newer version and publishes again.
118
95119## Read an artifact shared with you
96120
97121When someone shares an artifact with you, you can have Claude read it: give Claude its URL, or attach it from [`/artifacts`](#find-an-artifact-again).

145169Claude also stops replying on its own to an artifact after it handles 60 sent comments or thread activations on that artifact within an hour. You see `Comments are waiting on Artifact: <name>` once, and Claude picks up again as that hour's comments age out.
146170
147Run `/tasks` to see each artifact your session is watching, listed as a live-updates task. You can stop Claude from replying on its own in any of these ways:
171Run `/tasks` to see the artifacts your session is watching. `/tasks` groups the watches Claude Code started on its own under the **System tasks** row. Press `Enter` on that row to list them. A watch you asked Claude to start appears under **Monitors**.
148172
173You can stop Claude from replying on its own in any of these ways:
174
149175* **Press Ctrl+C once at an idle prompt**: Claude pauses replying on every artifact your session is watching. Replies start again after you send your next message.
150176* **Stop the task in `/tasks`**: Claude stops replying on that artifact until you ask it to resume replies there. Publishing the artifact again doesn't start replies again, and the stop still applies when you resume the session later.
151177* **Press `Ctrl+X Ctrl+K` twice within 3 seconds**: the chord that [stops every running background subagent](/docs/en/interactive-mode#general-controls) also stops Claude from replying on every artifact for the rest of the session. Asking Claude to resume replies doesn't undo this stop.

338364Whether artifacts are allowed for your organization comes from your organization's policy, which Claude Code loads from `api.anthropic.com`. When Claude Code can't load the policy, artifacts are unavailable. When you ask for one, Claude says why.
