Claude Code 2.1.283

[What's changed] Improved the Skill tool's reply when a skill belongs to a plugin that failed to load, so Claude tells you the plugin could not be loaded instead of calling the skill uninstalled

[What's changed] Added an opt-in `load_test_mode` block to the Claude apps gateway config: requests are built and signed but not sent upstream, and clients get a canned reply, so a deployment can be load tested

[What's changed] Added `availableModelsMatch` managed setting: with `"exact"`, an `availableModels` entry allows only the model version it names, so new releases stay blocked until listed

[What's changed] Added `deniedModels` managed setting to block specific models, even when `availableModels` allows them

[What's changed] Added `/doctor prompt-audit` (also `/checkup prompt-audit`) to audit your CLAUDE.md files, skills, agents and commands for prompting patterns written for older models

[What's changed] Improved the `/mcp` tool list: it shows more tools at once, scrolls with the page keys and mouse, and marks tools your organization blocked with a warning icon

[What's changed] Improved MCP tool results: images returned by MCP tools are now also saved to a file, so Bash, Read and other tools can open them

[What's changed] Improved `/tasks`: rows show a status icon, the name and whole facts, the title and key hints stay on screen with many tasks, and the list gains paging keys, the mouse wheel and clicks

[What's changed] Improved `prompt-audit` on Claude Code configuration: stale paths, stale commands and contradicting instruction files now lead the report, and thinking keywords that Claude Code documents are kept

[What's changed] Changed `--system-prompt` and `--append-system-prompt` to accept their text and `-file` forms together; the file's text comes first

[What's changed] [Cloud sessions] Improved adding a repository to a running cloud session: a private repository your GitHub account can read but not push to now attaches for reading

[What's changed] [Claude Tag] Added a "Channels Claude can search" admin setting that limits Claude's Slack search to public channels it has been added to, set per organization, workspace or channel

[What's changed] Added `x-claude-code-prompt-id` to the gateway hint headers so LLM gateways can group the requests that serve one user prompt; opt in with `CLAUDE_CODE_GATEWAY_HINT_HEADERS=1`

[What's changed] Added click-to-expand for truncated messages from your other sessions in fullscreen mode

[What's changed] Added a `mantle` upstream provider to the Claude apps gateway for Amazon Bedrock's Mantle endpoint

[What's changed] Improved lists beside a search box, such as `/skills` and `/artifacts`, to draw their pointer dim while the search box has the keys, so only one pointer is highlighted

[What's changed] Improved the compaction spinner: its timer now starts when compaction begins and it counts the summary's tokens as they stream, replacing the percentage bar

[What's changed] Improved the browser page shown after signing in to an MCP server: centered layout, dark mode, and new artwork

[What's changed] Changed the `/model` picker's Opus row and the Default model's name to drop "(1M context)" where Opus already has a 1M context window; the window is unchanged

[What's changed] Changed prompt suggestions in the terminal to appear less often after 20 in a row go unused; using one brings them back

[What's changed] Changed the `/workflows` run list to size itself like other lists: half the terminal inline, and it keeps its title on screen when the prompt shows below

[What's changed] Changed artifact watching: a watch that was armed automatically (not one you asked for) now ends after 3.5 hours with no activity; publishing or watching the artifact again re-arms it

[What's changed] [Cloud sessions] Changed new routine schedules to default to a few minutes past the hour, with a note that routines set exactly on the hour can start several minutes late

[What's changed] [Claude Tag] Added a Back to Slack button on the page shown after connecting your Claude account, returning you to the thread you started from

[What's changed] Added MCP tool, WebFetch and WebSearch outputs to the `tool.output` OpenTelemetry span event when `OTEL_LOG_TOOL_CONTENT=1`

[What's changed] Added `path` to `--plugin-dir` load-failure entries in the stream-json `system/init` `plugin_errors`, naming the directory that did not load

[What's changed] Fixed SDK sessions losing a deferred tool call or finished tool result when a turn ended early, a held approval prompt after a worker restart, and a non-streaming fallback's `result.usage`

[What's changed] Fixed MCP progress notifications being discarded once a long-running tool call moved to the background; the background task now shows the latest progress

[What's changed] Fixed `/model` accepting Sonnet 4.6 or Sonnet 5 with `[1m]` when the id carried a date or `-v1:0` suffix, in the cases where the plain id was refused

[What's changed] Fixed `/model` picker showing a hardcoded Haiku version and price when `ANTHROPIC_DEFAULT_HAIKU_MODEL` pins a different model

[What's changed] Fixed dynamic workflows started during a model fallback running every agent on the fallback model instead of retrying the configured model

[What's changed] Fixed `claude plugin validate` saying Claude Code accepts a plugin or marketplace name it cannot install; such names in `marketplace.json` now fail validation

[What's changed] Fixed `claude plugin uninstall` removing the other of two installed plugins whose ids differ only in case, with its options and secrets, when the one named had no `enabledPlugins` entry at that scope

[What's changed] Fixed `installed_plugins.json` being rewritten, losing records, when it holds a record this version cannot read; `claude plugin` commands now name the record and say how to recover

[What's changed] Fixed `claude mcp add`, `add-json`, and `remove` reporting success when the user or local config file could not be written, for example inside a sandbox

[What's changed] Fixed the first words of a reply in a cloud session sometimes appearing late instead of streaming as Claude writes them

[What's changed] Fixed Claude's built-in keybindings guide saying chords time out after 1 second instead of 3, and calling `cmd` an alias of `meta`, which could produce `cmd+` shortcuts most terminals never send

[What's changed] Fixed worktree checkouts failing certificate verification (for example on Git LFS downloads) when the CA certificate is passed to git as `GIT_CONFIG_COUNT` environment pairs

[What's changed] Fixed sandboxed `git` asking credential helpers to store the sandbox proxy's login, which printed "failed to store"

[What's changed] Fixed managed `sandbox` settings being ignored entirely when one nested value was invalid; the invalid value now fails closed and the rest of the block still applies

[What's changed] Fixed Claude's edits to its own auto-memory notes being blocked as sensitive-file writes when Claude Code was started in a subdirectory of a git repository

[What's changed] Fixed Remote Control being unavailable on paid plans when telemetry is turned off with `DISABLE_TELEMETRY` or `DO_NOT_TRACK`

[What's changed] Windows: Fixed the PowerShell tool letting `cmd /c rd`, `rmdir`, `del` or `erase` delete drive roots, the home folder and other folders that `Remove-Item` refuses

[What's changed] Changed `claude plugin eval` to require git 2.31 or later when git is installed; a run on an older git is refused with a message naming the version

[What's changed] [VSCode] Fixed the permission mode indicator showing Default while the session kept running in auto or bypass mode after an automatic switch out of it failed; the switch is now retried until it lands

[What's changed] [VSCode] Fixed a session teleported from the web dropping the messages sent while Claude was working

[What's changed] [VSCode] Fixed a Web session staying hidden from the session list, and an empty chat opening in its place, when an older version had saved an empty local copy of it

[What's changed] [VSCode] Fixed a reopened session splitting a turn at a message Claude received mid-turn, such as an automatic continuation

[What's changed] [VSCode] Fixed a reloaded session showing a rewound-away turn, or only the rows before a compaction

[What's changed] [Claude Tag] Fixed access-bundle repository search missing repositories on GitHub App installs that are limited to a large list of selected repositories

[What's changed] [Claude Tag] Fixed Claude occasionally posting the same reply twice when a new message interrupted it mid-reply

[What's changed] [Code Review] Fixed "@claude review" requests going silent when GitHub failed to return the pull request: the request is retried once, and a comment explains if it still fails

[What's changed] [Code Review] Fixed billing for a review that stopped at its time limit with nothing verified: it now shows as incomplete, isn't charged, and is retried once

[What's changed] Fixed stdio MCP servers being left running when the session ended while they were still starting

[What's changed] Fixed a brief HTTP 404 from a stateless remote MCP server (for example a proxy mid-redeploy) leaving that server unusable for the rest of the session while still shown as connected

[What's changed] Fixed MCP sign-in for a server with no valid URL failing with an opaque SDK error; `/mcp` no longer offers Authenticate for such servers

[What's changed] Fixed the weekly Fable limit not appearing in `/usage` and the VS Code usage meters when telemetry is disabled

[What's changed] Fixed `DISABLE_PROMPT_CACHING_HAIKU` having no effect when Haiku is the session's main model

[What's changed] Fixed `claude plugin details` showing 0 MCP servers for plugins that declare their servers in `plugin.json`

[What's changed] Fixed `claude plugin marketplace remove` not saying which installed plugins it uninstalled with the marketplace; it now lists them

[What's changed] Fixed plugins that declare no version being silently restored at their source's newest commit, not the installed one, when their cached files were missing

[What's changed] Fixed user-installed plugins and marketplaces failing to load with "cache-miss" after the home or config directory was moved, for example in bind-mounted devcontainers

[What's changed] Fixed `installed_plugins.json` showing no plugins when it holds a record under an invalid plugin id; such a file loads again

[What's changed] Fixed permission dialogs in screen-reader mode reading quoted commands and paths as if they were the dialog's own text

[What's changed] Fixed `/context` not counting MCP server instructions: they now appear as their own row and count toward the total

[What's changed] Fixed markdown links in the Warp terminal rendering as plain text instead of clickable hyperlinks

[What's changed] Fixed `keybindings.json` silently accepting a misspelled modifier such as `ctl+k`; it now warns in the debug log and suggests the fix

[What's changed] Fixed footer hints still saying "Enter to view" after `footer:openSelected` was rebound or unbound in `keybindings.json`

[What's changed] Fixed keys typed quickly together (type-ahead, key repeat, bursts over ssh or tmux) sometimes being handled against stale state

[What's changed] Fixed the `/remote-control` menu cutting its QR-code hint mid-word in narrow terminals

[What's changed] Fixed vim mode `.` dropping a Shift+Enter newline, leaving the cursor inside an accented letter, and repeating an older change after `3J` or Visual-mode `J` on the last line

[What's changed] Fixed vim mode cursor placement: recalling a prompt over 10,000 characters in normal mode no longer leaves the cursor past the end, and `V` then `p` now lands on the first non-blank

[What's changed] Fixed vim mode `J` joining lines with different spacing than Vim (such as a space before `)` or after a tab), and `3J` or Visual-mode `J` on the last line not moving the cursor as Vim does

[What's changed] Changed `/rewind` and `/diff` lists to move on the same keybinding actions as every other list (`select:*`); `messageSelector:*`/`diff:*` rebinds still work

[What's changed] Self-hosted runner: Changed lifecycle hooks' git to skip a repository's Git LFS `pre-push` hook, ignore a writable system `core.hooksPath`, and not sign commits without `--configure-git`

[What's changed] Self-hosted runner: Changed `GIT_SSL_CAINFO` and `GIT_SSL_NO_VERIFY` under Anthropic-managed git: the runner's own git always verifies Anthropic's git route, and warning lines say what applies where

[What's changed] [VSCode] Fixed the footer's agents pill drawing its icon off-center, with the status dot against the edge, in narrow panels

[What's changed] [VSCode] Fixed the chat input showing its text slightly below the cursor and selection after pasting lines that end with a line break into a long prompt

[What's changed] [Cloud sessions] Fixed cloud sessions occasionally redoing an already-finished step, such as posting a duplicate comment or push, after recovering from a server-side restart

[What's changed] [Claude Tag] Fixed a channel's configure page listing no connectors or plugins when the channel gets its access bundle through an attach rule; rule-attached bundles are now shown

[What's changed] [Claude Tag] Fixed channel routines that stopped running in older private channels whose Slack channel ID changed, for example after a Slack Connect share

[What's changed] [Claude Tag] Fixed conversations in a channel set to "Channel only" all ending when a non-guest member joined and Slack was slow to confirm their membership
