v2.1.292

What's changed

• Added --marketplace <source> to claude plugin install: adds the marketplace if needed, under the same policy checks as claude plugin marketplace add, then installs the plugin from it
• Added an effort parameter to the Agent tool, so Claude runs a sub-agent at the effort level you ask for
• Added CLAUDE_CODE_OVERLOADED_RETRY_BASE_DELAY_MS environment variable to set a longer base delay for the backoff when retrying an overloaded (529) request
• Added prompt.autocomplete, an event a mod hooks to add its own rows to the prompt box's autocomplete list
• Added prompt caching to $.model.complete for mods: prompt and system take blocks of text, and cache: true on a block caches the request up to it
• Added workflow agents to the agent.spawn mod hook, with their run and index, so a mod can refuse them
• Fixed subagent definitions with permissionMode: auto entering auto mode when auto mode is unavailable (disabled by settings, circuit breaker, or a model that doesn't support it)
• Fixed sandboxed commands being able to read the staged file copies of /ultrareview uploads under ~/.claude/seed-admin
• Fixed a managed sandbox read-deny path (and user ones beside it) that appears or re-points mid-session not dropping project grants inside it or ending credential injection from files it covers
• Fixed a notebook or PDF read on macOS and Windows being able to return a file outside what was approved, through a link swapped in mid-read
• Fixed a tampered on-disk cache of server-managed settings being able to switch off or unseat the built-in policy plugin while the settings fetch failed
• Fixed rm -rf on the 8.3 short name or another alternate Windows spelling of the home folder or a drive not being treated as removing it
• Security: Fixed PreToolUse hook approvals and auto mode bypassing the permission prompt for file reads from network (UNC) paths
• Fixed a skill's or slash command's allowed-tools rule coming back in a later turn when you leave auto mode or plan mode partway through that turn
• Fixed NO_PROXY being ignored for Claude Code's own API requests (sign-in, policy, feedback, artifacts) when HTTPS_PROXY is set
• Fixed an MCP tool with a name longer than 128 characters making every request fail; that tool is now left out and an MCP error names it
• Fixed claude plugin commands such as marketplace add and install running before an organization's managed settings had loaded on a first run
• Fixed one-shot claude -p and Agent SDK runs stopping a background command 5 seconds after the final result, and one-shot claude -p runs dropping a scheduled wakeup; both are now waited for
• Fixed plan mode not being restored when resuming a session from the claude --resume session picker or with /resume
• Fixed saved scheduled tasks created after /resume, /branch or /clear never firing, and saved tasks ignoring later creates and deletes after two writes to the tasks file milliseconds apart
• Fixed a background session's /loop silently stopping when the session's process restarted (for example after a crash), because its pending wakeup was lost
• Fixed Grep and Glob reporting no matches when the file or folder they were given could not be read; Claude now retries once or tells you
• Fixed the Read tool returning only the first entry, with no error, when a PDF's pages was a list such as "6,9,15"; it now returns an error saying to read each page or range separately
• Fixed @-mentioned text files over 256KB being left out silently: Claude is now told the file's size and to read it in portions
• Fixed the usage limit alert repeating once per background agent when agents failed on a limit that had already stopped the main conversation
• Fixed Remote Control viewers seeing an empty subagent pane for background subagents in sessions hosted by the desktop app or an IDE
• Fixed cross-session delivery notices showing two sessions with similar names as one recipient, and the expiry notice blaming the desktop app when a terminal session let the message lapse
• Fixed Send now in the desktop app ending the subagent a turn was waiting on when another message was already queued
• Fixed /bug, /share and /feedback <text> starting over after Ctrl+O or Ctrl+Z while a report was being sent, and closing as cancelled after it had been sent
• Fixed /remote-env replacing your saved default environment when you pressed Enter right away: the list now opens on your default, and no row has a check mark when no default is in effect
• Fixed some pasted text reaching Claude as typed text when several pastes overlapped in one prompt
• Fixed vim mode leaving the cursor past the end of a line, j/k losing their column on shorter lines, and f/t/F/T/;/, jumping to, or deleting up to, a match on another line of the prompt
• Fixed /add-dir path box letting Shift+Enter or a paste add a line break, and treating fast-typed "tab", "up" or "down" as those keys
• Fixed fast typing, input-method text and decomposed accents being dropped while a prompt footer row was selected, and ! leaving the row selected
• Fixed fullscreen mode sending a full-screen clear on every window resize and Ctrl+L when iTerm2 is detected, which may be what filled iTerm2's scrollback with stale pages
• Fixed a spurious "could not be examined" note for @-words that name no file when a Read deny rule is set and the working directory is under a symlink
• Fixed "instruction file not loaded" lines going stale or missing after /cd or a permission change, and added a transcript line when a nested one isn't loaded
• Fixed a compaction summary that repeated /name letting Claude invoke a skill that is reserved for the user
• Fixed Write, Edit, NotebookEdit and LSP rows, and single Read, Grep and Glob rows, hiding why a mod denied the call: the row now shows the reason
• Fixed a cloud session showing a turn that never ended when its worker was stopped just as the turn finished
• Fixed cloud sessions with a large transcript sometimes asking for a permission again after it was approved
• Fixed scheduled tasks and other queued notifications being lost in cloud sessions when a message was retried or edited while Claude was reading them
• Fixed cloud sessions forgetting the thinking setting chosen in the client when the session's container restarted
• Fixed Cowork cloud sessions saying a proxy blocked artifacts when Anthropic couldn't confirm the organization's settings
• Fixed plugins whose hooks module makes many $.state calls through one const taking minutes to load or validate
• Fixed claude plugin validate listing a matcher or state value for a hooks module that the engine reads from elsewhere
• Fixed claude plugin validate listing a $.state value read through a top-level var that was declared again or reassigned; such a module is now refused
• Fixed a plugin's served $ method restarting the hook origin, which could run a guard hook with a .catch above it again without end
• Fixed plugin interface calls made while the plugin hooks worker restarts running without the hooks other plugins put on them
• Fixed a mod's config.set, state.set, env.set or agent.spawn hook that denies after calling next(e) being answered as a refusal: the hook is now reported as failed, by name
• Fixed /theme, the /config Theme menu and the first-run theme step saving a theme before a plugin's config.set hook was asked
• Fixed a plugin's tool.check hook answering allow running a tool that requires your answer (a question, a plan approval) without showing its dialog
• Fixed a mod's start-up prompt, command or subagent being queued a second time when the hooks worker was replaced
• Fixed a mod's hook that called next(e) and then failed while the turn was interrupted letting the call through; the call is now rejected
• Fixed a plugin's prompt drop or setting deny being ignored when its reason was longer than 4,096 characters
• Fixed an organization's plugin being unloaded on its own reload, or after another plugin crashed, when it returned a $ name that a user-installed mod had added; the mod is now unloaded instead
• Fixed tool calls made while the plugin hooks worker restarts being answered without the plugins' permission hooks
• Fixed plugin tool.call hooks seeing some tool calls before misnamed parameters were repaired; a hook now sees the arguments the tool will run with
• Fixed a mod's guard hook with a .catch being skipped silently for calls another mod's hook makes beneath the guard's own $ call; its .catch is now asked
• Improved startup of claude -p and SDK sessions: the first turn no longer waits for HTTP and SSE MCP servers to answer resources/list
• Improved rendering speed of long bulleted or numbered replies: they stream, resize and re-open in the transcript (ctrl+o) much faster
• Improved Ctrl+C draft recovery: a cleared prompt now stays reachable with Up after a slash command or a sent message
• Improved hook output handling: <system-reminder> tags written in a hook's output are escaped before they reach Claude
• Improved tool input handling: Grep accepts file_path for path, and Write, WebFetch and Read ignore a few stray parameters instead of failing the call
• Improved the steps shown when a marketplace declared in a settings file has a name that looks like an official Anthropic marketplace
• Improved sandbox auto-allow: with strict sandbox mode set in user, managed or --settings settings, an interpreter command with an env var prefix like FOO=bar python3 app.py runs unprompted
• Improved the Artifact tool's listing: Claude now sees how many published artifacts you have and can list up to 200 at once instead of 50
• Improved cloud sessions after a restart: Claude is now told which stopped background agents it can resume by id
• Improved the Claude in Chrome message in claude.ai cloud sessions when the browser can't be reached: Claude is now told it may continue with alternatives if the user prefers
• Improved the /focus tip: it now invites you to try focus view mid-turn and shows how to switch back
• Improved startup with local (stdio) MCP servers that ignore the newer protocol check: after one slow connect they are remembered for 7 days and connected the older way without the wait
• Changed local (stdio) MCP server connections to negotiate protocol version 2026-07-28 by default on every install, including Bedrock, Vertex and Foundry; MCP_PROTOCOL_NEGOTIATION=legacy opts out
• Changed claude plugin test: a failed expect inside a hook the test registered, or a stub answer the engine refuses, now fails the test instead of passing silently
• Changed usage limit messages to write claude.ai settings links with https:// so terminals and apps can make them clickable
• Changed scheduled and Run now routine runs to publish a new artifact only you can see without asking for approval; artifacts that request connectors or other access still ask
• Changed agent names to allow at most 256 characters: a longer one is rejected, and a skill's or a plugin file's name longer than that is ignored
• [Cloud sessions] Fixed routine runs occasionally staying listed as running for hours after they had finished
• [Cloud sessions] Fixed editing or duplicating a routine turning off its push notifications when the routine had no saved notification setting
• [Cloud sessions] Fixed SVG, HEIC, TIFF and other less common image files failing to attach; they now attach as regular files
• [Cloud sessions] Fixed approval prompts offering "Always allow" for connector tools that an organization set to require approval; the choice had no effect
• [Remote Control] Fixed the first message of a new Remote Control session started from claude.ai/code accepting only images; it now accepts PDFs and other files like later messages
• [Claude Tag] Added an Edit button to the Allowed domains card on a channel's Configure page, so Enterprise admins can open the access bundle that sets the channel's domains
• [Claude Tag] Fixed replies sent in a Slack thread while Claude was still on its first request there being held until that request finished, or missed when sent seconds apart
• [Claude Tag] Fixed Slack threads woken only by GitHub pull request activity or a routine staying on their original model after an admin changed the channel or workspace default model
• [Claude Tag] Fixed Claude sometimes posting a spend limit notice in Slack when the real cause was that your organization had run out of usage credits
• [Claude Tag] Fixed a session hanging until interrupted when a permission prompt that can't be answered from Slack was denied automatically
• [Claude Tag] Improved @Claude !status in a channel to say when Claude has stopped reading its untagged messages, why, and that an @-mention starts it reading again
• [Claude Tag] Changed the first message of a Slack thread continued with !fork to a card showing where it came from, the request, and who asked, with a link to the original thread
• [Claude Tag] Changed the organization-wide and default spend limit boxes on Claude Tag's spend limits page in admin settings to save only when you press Save or Enter, not when you click away
• [Code Review] Added the period's total with its change from the previous period, and a breakdown by repository, to the PRs reviewed chart in Code Review analytics
• [Code Review] Fixed a queued review failing when the pull request moved to a new base branch and the old one was deleted; the commit is now re-queued for review
• [Code Review] Fixed reviews ignoring a CLAUDE.md's rules when the pull request edits that file; reviews now use its version from the base branch
