この更新の概要
セッションの出力をプライベートなWebページとして公開できるArtifacts機能が導入されました。この新機能に伴い、自動ブラウザ起動の制御や機能自体の無効化を行う新しい環境変数と設定項目が追加されています。また、Artifactsを表示するためのネットワーク構成要件や用語定義、データ保持に関するポリシーも整備されました。チームまたはエンタープライズプランでの利用が可能となり、認証方法や共有範囲に関する詳細が公開されています。

### Link output back to the session
Each cloud session has a transcript URL on claude.ai, and the session can read its own ID from the `CLAUDE_CODE_REMOTE_SESSION_ID` environment variable. Use this to put a traceable link in PR bodies, commit messages, Slack posts, or generated reports so a reviewer can open the run that produced them.

| `CLAUDE_CODE_ALT_SCREEN_FULL_REPAINT` | Set to `1` to repaint the entire screen on every frame in [fullscreen rendering](/en/fullscreen) instead of sending incremental updates. Use this if fullscreen mode shows stale or misplaced text fragments. Claude Code enables this automatically for background sessions and [agent view](/en/agent-view) on Windows |
| `CLAUDE_CODE_ALWAYS_ENABLE_EFFORT` | Set to `1` to send the [effort](/en/model-config#adjust-effort-level) parameter with every request, even when Claude Code does not recognize the model ID as effort-capable. Use this when routing through an [LLM gateway](/en/llm-gateway) or third-party provider that serves models under custom identifiers. Models that reject the effort parameter at the API, including Claude 3 models, Sonnet 4.0 and 4.5, Opus 4.0 and 4.1, and Haiku 4.5, are still excluded so requests do not fail |
| `CLAUDE_CODE_API_KEY_HELPER_TTL_MS` | Interval in milliseconds at which credentials should be refreshed (when using [`apiKeyHelper`](/en/settings#available-settings)) |
| `CLAUDE_CODE_ARTIFACT_AUTO_OPEN` | Set to `0` to stop Claude Code from opening the browser automatically when a new [artifact](/en/artifacts) is published. Republishing an existing artifact does not open the browser regardless of this setting |
| `CLAUDE_CODE_ATTRIBUTION_HEADER` | Set to `0` to omit the attribution block (client version and prompt fingerprint) from the start of the system prompt. Disabling it improves prompt-cache hit rates when routing through an [LLM gateway](/en/llm-gateway). Anthropic API caching is unaffected |
| `CLAUDE_CODE_AUTO_COMPACT_WINDOW` | Set the context capacity in tokens used for auto-compaction calculations. Defaults to the model's context window: 200K for standard models or 1M for [extended context](/en/model-config#extended-context) models. Use a lower value like `500000` on a 1M model to treat the window as 500K for compaction purposes. The value is capped at the model's actual context window. `CLAUDE_AUTOCOMPACT_PCT_OVERRIDE` is applied as a percentage of this value. Setting this variable decouples the compaction threshold from the status line's `used_percentage`, which always uses the model's full context window |
| `CLAUDE_CODE_AUTO_CONNECT_IDE` | Override automatic [IDE connection](/en/vs-code). By default, Claude Code connects automatically when launched inside a supported IDE's integrated terminal. Set to `false` to prevent this. Set to `true` to force a connection attempt when auto-detection fails, such as when tmux obscures the parent terminal. Takes precedence over the [`autoConnectIde`](/en/settings#global-config-settings) global config setting |

| `CLAUDE_CODE_DISABLE_AGENT_VIEW` | Set to `1` to turn off [background agents and agent view](/en/agent-view): `claude agents`, `--bg`, `/background`, and the on-demand supervisor. Equivalent to the [`disableAgentView`](/en/settings#available-settings) setting |
| `CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN` | Set to `1` to disable [fullscreen rendering](/en/fullscreen) and use the classic main-screen renderer. The conversation stays in your terminal's native scrollback so `Cmd+f` and tmux copy mode work as usual. Takes precedence over `CLAUDE_CODE_NO_FLICKER` and the [`tui`](/en/settings#available-settings) setting. You can also switch with `/tui default`. Does not apply to background sessions opened from [agent view](/en/agent-view), which always use fullscreen rendering |
| `CLAUDE_CODE_DISABLE_ARTIFACT` | Set to `1` to disable the [Artifact](/en/artifacts) tool, which publishes session output as a private web page on claude.ai. Equivalent to the [`disableArtifact`](/en/settings#available-settings) setting |
| `CLAUDE_CODE_DISABLE_ATTACHMENTS` | Set to `1` to disable attachment processing. File mentions with `@` syntax are sent as plain text instead of being expanded into file content |
| `CLAUDE_CODE_DISABLE_AUTO_MEMORY` | Set to `1` to disable [auto memory](/en/memory#auto-memory). Set to `0` to force auto memory on even when `--bare` mode or [`autoMemoryEnabled: false`](/en/settings#available-settings) would otherwise disable it. When disabled, Claude does not create or load auto memory files |

| `CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST` | Set by host platforms that embed Claude Code and manage model provider routing on its behalf. When set, provider-selection, endpoint, and authentication variables such as `CLAUDE_CODE_USE_BEDROCK`, `ANTHROPIC_BASE_URL`, and `ANTHROPIC_API_KEY` in settings files are ignored so user settings cannot override the host's routing. The automatic telemetry opt-out for Bedrock, Vertex, and Foundry is also skipped, so telemetry follows the standard `DISABLE_TELEMETRY` opt-out.

| `CLAUDE_CODE_RESUME_PROMPT` | Override the continuation message injected when resuming a session that ended mid-turn. Defaults to `Continue from where you left off.`. Spawn scripts for long-running agents can set this to a more directive boot message. An empty string uses the default |
| `CLAUDE_CODE_SAFE_MODE` | Set to `1` to start in safe mode: CLAUDE.md, skills, plugins, hooks, MCP servers, custom commands and agents, output styles, workflows, custom themes, custom keybindings, status line and file-suggestion commands, LSP servers, and auto-memory do not load, for troubleshooting a broken configuration. Managed settings policy still applies, including policy-configured hooks, status line, and file-suggestion commands; managed plugins, managed skills, managed CLAUDE.md, and policy-configured MCP servers do not.

### Artifact
A live, interactive web page Claude Code publishes from your session to a private URL on claude.ai, so you can see output visually or share it inside your organization instead of reading terminal text. The page updates in place when the session republishes. Artifacts you create from Claude Code appear in the same gallery as artifacts created in claude.ai conversations, but their sharing stops at your organization and they cannot be made public.

### Auto memory
Notes Claude writes for itself based on your corrections and preferences, stored per git repository under `~/.claude/projects/`. All worktrees of the same repository share one auto memory directory. The first 200 lines or 25 KB of the `MEMORY.md` index loads at the start of every session. Auto memory is the Claude-written counterpart to [CLAUDE.md](#claude-md), which you write.
