feature patch

Anthropic has released Claude Code v2.1.269, introducing new capabilities like `claude plugin eval` for scoring plugin suites and increased `CLAUDE_CODE_WORKFLOW_MAX_CONCURRENT_AGENTS` for workflow tool fan-outs. The update enhances the Bash tool with file change diffs, adds OpenTelemetry repository tagging, and improves output style switching. It also addresses numerous bugs affecting prompt caching, terminal compatibility, remote sessions, plugin connectivity, and error handling for long-running goals. These improvements aim to boost developer productivity and the reliability of AI-assisted coding.

  • →Added /output-style [name] to list and switch output styles, including over Remote Control and in cloud and other headless sessions
  • →Added a diff of the files a Bash command changed to the Bash tool result when the Bash tool handles file edits (setting bashEditDiffEnabled)
  • →Added CLAUDE_CODE_GATEWAY_MODEL_DISCOVERY_TIMEOUT_MS to extend the LLM gateway /v1/models discovery timeout (default 3s)
  • →Added a spinner tip suggesting /focus for a view with just your prompt, a one-line work summary, and the response
  • →Fixed the terminal's replies to capability queries (^[[?1;2c) appearing as stray text at startup in some terminals
Features (7) ›

  • Added claude plugin eval: run a plugin's eval suite against Claude Code and get scored, reproducible results (JSON + HTML report); see claude plugin eval --help

  • Added /output-style [name] to list and switch output styles, including over Remote Control and in cloud and other headless sessions
  • Added a diff of the files a Bash command changed to the Bash tool result when the Bash tool handles file edits (setting bashEditDiffEnabled)

  • Added OTEL_METRICS_INCLUDE_REPOSITORY to tag OpenTelemetry metrics and events with vcs.* repository attributes; commit events get vcs.ref.head.* with OTEL_LOG_TOOL_DETAILS

  • Added CLAUDE_CODE_GATEWAY_MODEL_DISCOVERY_TIMEOUT_MS to extend the LLM gateway /v1/models discovery timeout (default 3s)
  • Added a spinner tip suggesting /focus for a view with just your prompt, a one-line work summary, and the response

  • Added CLAUDE_CODE_WORKFLOW_MAX_CONCURRENT_AGENTS (1–256) to raise the Workflow tool's per-run concurrent agent limit for inference-bound fan-outs

Enhancements (9) ›
  • Improved the /diff panel to open fully rendered in one step instead of showing a loading state first

  • Improved prompt suggestion filtering for Japanese, Chinese and Korean text: mixed-script and single-word suggestions are kept, and meta or evaluative text is dropped as it is for English

  • Improved the Skill tool's "Unknown skill" error to name the plugin skill's full name when a bare name matches exactly one plugin skill

  • Improved keyboard support over SSH and in unrecognized terminals: terminals that answer the kitty keyboard query (such as foot and Alacritty 0.16+) now get Shift+Enter and Ctrl+Shift shortcuts

  • Improved responsiveness in long sessions: transcript updates no longer re-process the whole conversation to build the collapsed tool-use summaries

  • Improved first-party sessions with telemetry disabled: an alwaysLoad MCP server that finishes connecting mid-conversation is usable on the next turn without a tool-search round trip

  • Changed /ultrareview --post to post the PR comment directly when the findings arrive and print the comment link, instead of starting a second cloud session to post it

  • Changed artifact database reads that save into the session scratchpad so they no longer stop for working-folder approval

  • Changed skills synced from claude.ai in cloud sessions to be named anthropic-skills:<name>, matching Claude Desktop; the bare name still works when nothing else uses it

Fixes (41) ›

  • Fixed the prompt cache being partially invalidated on the turn after a response was cut off at the output-token limit and automatically resumed

  • Fixed a case where resuming a session after interrupting Claude mid-thought could change how earlier context was re-sent, hurting prompt-cache reuse

  • Fixed F1/F2/F4 not working in kitty-protocol terminals and Delete in st, Alt+arrows acting as Escape in rxvt-unicode, and Shift+punctuation typing the unshifted key in WezTerm (regression in 2.1.247)

  • Fixed remote and headless sessions reporting "waiting for your input" while background agents were still running (set CLAUDE_CODE_BG_TASKS_REPORT_RUNNING=0 to restore the old behavior)

  • Fixed the terminal's replies to capability queries (^[[?1;2c) appearing as stray text at startup in some terminals
  • Fixed rows at the top or bottom of the transcript going blank in fullscreen after resizing the terminal

  • Fixed a deny or ask permission rule starting with ! applying beyond the settings source that wrote it; such a rule now applies only within its own source, and a bare ! negation is ignored

  • Fixed the git status Claude is told after a compaction: it is now the current status, not the one from the start of the session
  • Fixed synced plugin MCP servers not connecting when a remote session resumes
  • Fixed resumed headless sessions losing a turn's replies when the model was switched or a request was retried mid-turn

  • Fixed terminal escape codes, line breaks and oversized text from a background task's on-disk record reaching the task list and task notifications when work is resumed

  • Fixed CMYK JPEG images failing to attach with "cannot decode"; they are now converted and resized like other JPEGs
  • Fixed the managed settings approval dialog not naming the collector for a gRPC telemetry endpoint set without a scheme
  • Fixed plugin headersHelper consent prompts showing a URL path that could be misread as a different host
  • Fixed plugin errors showing [redacted URL] in place of a relative Windows path with a folder name that starts with @

  • Fixed missing cursor in the permission-rule, auto-mode-rule, add-directory, session-rename and feedback-review text fields when the terminal's native cursor is enabled

  • Fixed repeated clicks on a /fork receipt, each under a second apart, never backgrounding the session right away while it waited for the current tool to finish

  • Fixed plugin LSP servers that reject shutdown params (e.g. rust-analyzer) being left running at session end; exit is now sent even if shutdown fails

  • Fixed the attribution reminder overriding a CLAUDE.md or memory rule against commit and pull request attribution; lines set by managed settings still apply

  • Fixed prompt suggestions being dropped for text in Japanese, Chinese, Thai and other languages written without spaces between words
  • Fixed synchronized output being assumed from the terminal's name in GNOME Terminal and Konsole versions that do not support it
  • Fixed permission_denials in --output-format stream-json results omitting Read, Edit and Write calls blocked by a path-scoped deny rule
  • Fixed sessions run through the SDK or the desktop app showing an unknown status in other sessions' agent list

  • Fixed /insights failing on Bedrock, Vertex, Foundry, and gateway deployments whose account can't reach the default Opus model by using the session model there instead

  • Fixed organization policy limits not loading for the session when another Claude Code process refreshed the login at the same moment
  • Fixed Claude Desktop sessions using Bedrock, Vertex, or a gateway not getting the contextual "what Claude needs" turn-end notification text
  • Fixed MCP servers reconnecting when an updated config only changed the order of the server URL's query parameters

  • Fixed the prompt box's top border splitting into extra lines when viewing a background agent whose name or description has line breaks or is wider than the terminal

  • Fixed sessions getting permanently stuck on "Prompt is too long" when auto-compaction had no complete earlier exchange to summarize (mostly Agent SDK sessions with very large prompts)

  • Fixed /goal runs silently stalling after API errors, network drops, or token limits: the goal now retries with backoff, or pauses and says why, including until a usage limit resets

  • Fixed prompt cache misses in cloud sessions by waiting briefly for server configuration before the first request

  • Fixed /btw answers that contained made-up tool calls and output: the side question is now told not to write them, and any that appear are flagged as not executed

  • Fixed CLAUDE_CODE_RESUME_INTERRUPTED_TURN re-running a turn that had failed with an API error over 6 hours earlier, or longer ago than CLAUDE_CODE_RESUME_INTERRUPTED_TURN_MAX_AGE_MS when set

  • Fixed organization plugins enabled through managed settings not loading in headless sessions and on Claude Desktop (once Desktop bundles this CLI version); they load from the next session

  • Fixed plugin archives extracted for a session being readable by other local users, extracted files keeping world-writable bits from the archive, and stale files surviving re-extraction

  • Fixed Edit() deny rules and the write-path check not applying to the file a Bash tee command writes; a Bash(tee:*) allow rule no longer covers destinations outside the working directories

  • Fixed stray characters like 22c, or a terminal's color or version reply, being typed into the prompt at startup over slow connections (ssh, browser terminals)

  • Fixed the terminal's block cursor showing under the interface in rxvt-unicode after leaving or re-entering fullscreen
  • Fixed the cursor block staying visible after returning from an external editor in fullscreen mode on rxvt-unicode
  • Fixed the interface being drawn twice after returning from an external editor (Ctrl+G) outside fullscreen mode
  • Fixed the interface being drawn twice in Konsole after returning from an external editor
