Claude Code v2.1.248

What's changed

• Added --restricted (or CLAUDE_CODE_RESTRICTED=1): removes the built-in tools that run commands or code and WebFetch (unless named in --tools), keeps file tools inside the working directory, refuses bypassPermissions, and ignores user, project and local settings files
• Added experimental.cacheTtl ("5m" or "1h") to agent frontmatter: a per-agent prompt cache TTL used when no subagent TTL setting is configured
• Added claude self-hosted-runner --client-label <label> (or SELF_HOSTED_RUNNER_CLIENT_LABEL) to override the label the runner registers with (default: hostname)
• Added server-managed settings diagnostics: a startup warning when the settings fail to load, and a /doctor and /status line explaining a load failure or why they weren't fetched (Bedrock/Vertex/third-party provider, custom ANTHROPIC_BASE_URL)
• Added a warning in /web-setup when the GitHub CLI token lacks the workflow scope, since pushes to very large repositories can be rejected without it
• Added /usage-credits for Enterprise organizations billed through AWS Marketplace, self-serve Enterprise, and Enterprise trials, so members can request a higher usage limit from their admin
• Added cross-session messaging (SendMessage / ListAgents) between sessions on the same machine on Bedrock, Vertex, and Foundry, and when telemetry is disabled
• Fixed a prompt-cache miss (and lost extended-thinking context) roughly once an hour in long sessions, caused by tool definitions being re-rendered after an OAuth token refresh
• Fixed the ScheduleWakeup tool definition changing between a session and its --resume when the account had entered usage overage, causing a full prompt-cache miss on the resumed session's first turn
• Fixed Claude Desktop and Cowork sessions disappearing after 30 days: the transcript cleanup now keeps desktop-written sessions while they are in the app (unless org policy manages retention); the new desktopSessionCleanupPeriodDays setting caps the exemption
• Fixed being sent to the login screen when another Claude Code process held the token refresh lock while the session token had expired; the request now fails with a retryable error instead
• Windows: Fixed the claude agents list not responding to the keyboard after detaching from a session, or when launched in a terminal tab left in win32-input-mode
• Fixed the recommended Console sign-in in /login failing with an OAuth error before showing a sign-in URL on machines where it can't be used (for example when ANTHROPIC_API_KEY or an API key helper is set); it now falls back to the API-key sign-in
• Fixed model names in /model and fast-mode switch notices to render as code, so suffixes like [1m] display literally instead of as a link
• Fixed claude agents skipping the workspace trust prompt when the CI environment variable is set
• Fixed claude agents crashing on launch when the PR-status cache held a malformed entry
• Fixed agent view resurrecting a weeks-old background session after the machine was off: such a session now shows as stopped at its real end, and opening it asks before resuming its saved conversation
• Fixed agent view sometimes opening an older conversation, and dropping the typed prompt, when starting a new session
• Fixed claude agents: opening a stopped session that you already resumed in another terminal no longer starts a second process on that conversation; the row now says it is open in a terminal
• Fixed claude agents and claude rm refusing to delete a session ("has commits that are not pushed anywhere") when its worktree branch was already merged into your checked-out default branch (e.g. local main) but not yet pushed
• Fixed background sessions waiting silently when a PermissionRequest or PreToolUse hook prints an invalid answer: the claude agents row now names the hook and the schema error
• Fixed hooks silently treating a stdout {…} object that isn't valid JSON as plain text; it's now r
