Claude Code 2.1.233

When a teammate sends a GitLab merge-request URL, you can now give that URL to --worktree and recognize it in the claude agents view. A worktree is a parallel copy of a Git project, so you can inspect changes somewhere separate from current work.

Merge requests appear as !N, making their GitLab identity visible in the list.

If your company connects to Anthropic upstreams through an apps gateway and needs to assign spending to people, it can opt into forward_user_identity. This setting puts the signed-in user's identity into request headers for a proxy behind the gateway.

Leave it off and that identity is not forwarded.

When a build runs through the Bash tool on Linux, you can opt into CLAUDE_CODE_TOOL_MEMORY_LIMIT if a runaway build might stall the session. It enables a memory cgroup, Linux's boundary for the memory available to a group of programs.

The optional limit keeps a runaway build from stalling the session.

Within one WebFetch session, you can now set CLAUDE_CODE_WEBFETCH_CACHE_TTL_MS to choose how long its URL cache lasts. A cache keeps a URL lookup result for direct reuse during the session; this variable controls that lifetime.

The default remains 15 minutes.

When starting claude self-hosted-runner, the session branch is now created without rewriting the worktree. A session is the connection and state for one continuous stretch of work, and its start no longer waits for two server round trips that blocked the agent launch.

The runner's session starts faster because those two round trips no longer block the agent.

When an apps gateway receives a 400 or 413 error from Vertex, Foundry, or Claude Platform on AWS, it now carries the upstream service's own message. An upstream is the service the request was meant to reach, so its message tells you why it rejected the request.

A bug in auto-compact on apps gateway is fixed. Auto-compact condenses earlier conversation to make room for more content in a session.

Auto-compact through apps gateway is no longer affected by this bug.

When checking a plugin, claude plugin validate now examines a bare .claude/skills directory. It reports SKILL.md files whose frontmatter, the fields at a file's beginning for tools to read, cannot be parsed.

Validation includes .claude/skills even when it stands alone rather than inside a full structure.

When using a screen reader to change /effort, the selector now appears as a numbered list and asks for a typed number. A screen reader is an assistive tool that reads screen content aloud and needs an ordered way to convey choices.

Hint text and dialog text are no longer clipped either.

If print mode sends a model ID Claude Code does not recognize, stderr, the program's text channel for reporting problems, now writes [claude-code:unrecognized_model]. The diagnostic line tells you the request went out with an unknown model ID.

Map that ID with modelOverrides to silence the line.

If a repository's origin remote is on gitlab.com or bitbucket.org, the GitHub app setup tip no longer appears. An origin remote is the repository's destination for its remote source, so a non-GitHub destination should not ask for GitHub app setup.

The enterprise marketplace tip now covers internal Git hosts that are not GitHub.

On Opus 4.8, Sonnet 5, Fable 5, Mythos 5, and newer models, the task-tracking tools TaskCreate, TaskGet, TaskUpdate, TaskList, and TodoWrite are no longer available. This changes the availability of existing tools; it does not add a new tool.

Set CLAUDE_CODE_ENABLE_TODO_TOOLS=1 to restore them.
