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
AddedCLAUDE_CODE_OVERLOADED_RETRY_BASE_DELAY_MS environment variable to set a longer base delay for the backoff when retrying an overloaded (529) request
Addedprompt.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
Claude TagAdded 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
Code ReviewAdded 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
~changed 7
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
Changedclaude 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
Claude TagChanged 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 TagChanged 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
!security 1
Fixed PreToolUse hook approvals and auto mode bypassing the permission prompt for file reads from network (UNC) paths
↑improved 13
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
ImprovedCtrl+C draft recovery: a cleared prompt now stays reachable with Up after a slash command or a sent message
Improvedhook output handling: `<system-reminder>` tags written in a hook's output are escaped before they reach Claude
Improvedtool 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
Improvedsandbox 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
Claude TagImproved@Claude !status in a channel to say when Claude has stopped reading its untagged messages, why, and that an @-mention starts it reading again

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
Fixedrm -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
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
FixedNO_PROXY being ignored for Claude Code's own API requests (sign-in, policy, feedback, artifacts) when `HTTPS_PROXY` is set

Fixedclaude 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 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/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 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

FixedWrite, 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 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
