system prompt +359 chars

Changelog:

Added screen reader mode: opt-in plain-text rendering for screen reader users. Run `claude --ax-screen-reader`, set CLAUDE_AX_SCREEN_READER=1, or add "axScreenReader": true to settings.
Added `vimInsertModeRemaps` setting: map two-key insert-mode sequences like `jj` to Escape in vim mode
Added `CLAUDE_CODE_PROCESS_WRAPPER`: agent view and the background service now honor a corporate launcher by running every Claude Code self-spawn through a required wrapper executable
Added mouse-click support for multi-select menus and "Other" input rows in fullscreen mode
Fixed fast mode staying off after switching back to a model that supports it — it now restores automatically when enabled in settings
Fixed replies typed to a background agent being lost when delivery fails — the text is now saved and delivered when the session restarts
Fixed background-session attach failing permanently ("Couldn't start the background daemon") after an update replaced the binary a running `claude agents` process was launched from
Fixed the context window (and auto-compact indicator) briefly resetting to 200k after the CLI auto-updates, causing a false "100% context used" when resuming long-context sessions
Fixed supervised and background sessions crashing when a server closed an HTTP/2 connection with a GOAWAY while requests were in flight
Fixed truncated stream-json/JSON output and missing result message when piping large responses from `claude -p`
Fixed `CLAUDE_CODE_MAX_OUTPUT_TOKENS` and similar env vars silently using the mantissa of scientific-notation values (`1e6` became `1`)
Fixed very large markdown tables stalling rendering or using excessive memory; tables over 200 rows show the first 200 with a "… N more rows" notice
Fixed the Edit tool failing on files modified after reading when the target text still matches uniquely
Fixed Read reporting empty files as "shorter than offset", Grep silently returning "No files found" for invalid regex patterns, Grep count mode under-reporting totals when paginated, and Glob crashing with an unclear error when the pattern, path, or working directory contained a null byte
Fixed `apiKeyHelper` script failures being hidden behind a generic 401 after ~10 silent retries; the script's own error is now shown within 3 attempts
Fixed Bedrock streaming requests failing with a misleading "Truncated event message received" when a gateway transforms the response — the error now names the content-type and points at the proxy
Fixed `/upgrade` showing a login flow instead of the upgrade URL when the browser fails to open
Fixed stream-json input killing the session on blank CRLF or whitespace-only lines from Windows-style SDK hosts
Fixed headless stream-json sessions hanging permanently when a `control_request` carried a non-string `set_model` payload; the CLI now answers with an error response
Fixed repeated "No completion record was found" notices on session resume — orphaned background tasks now collapse into a single summary
Fixed Remote Control clients attaching to a terminal-hosted session not seeing background agents and workflow progress until a task started or stopped
Fixed the Agent tool launching with no tools when a subagent's `tools` list resolves to nothing — it now returns a clear error naming the unrecognized entries
Fixed `/usage` showing stale cached bars over fresher data, and `/mcp` not reclassifying placeholder servers after config edits
Fixed "Change directory" in SDK hosts (e.g. Claude Desktop) failing with "A turn is in progress" on idle sessions that have a running background task
Fixed the workflow save dialog showing `~/.claude/workflows/` instead of the `CLAUDE_CONFIG_DIR` location for user-scope saves
Fixed `/release-notes` adding the viewed notes to the model's context — "Show all" previously injected the entire changelog into every subsequent request
Fixed a memory leak in the agent view where pasted images were retained for the screen's lifetime after sending peek replies
Fixed SDK sessions losing agents defined via the initialize request when a plugin refresh ran before the client attached
Fixed several memory leaks in long sessions: MCP stdio server stderr accumulating up to 64 MB per server, LSP documents staying open indefinitely (now LRU with 50-doc cap), async hook output retained after backgrounding, and unbounded growth in headless/SDK sessions from large tool-result payloads
Fixed a memory blowup when reading files with extremely long single lines using offset/limit — the read now returns a clean error instead of loading the whole line
Fixed multi-second per-turn slowdowns in sessions with many permission deny/ask rules — rule matchers are now compiled once and cached
Improved input responsiveness while agent task lists update — task updates no longer re-render the entire UI
Reduced per-tool-call CPU overhead in print/SDK sessions with many MCP tools by caching tool-pool assembly (up to 7x faster tool rounds at high tool counts)
Reduced memory usage by bounding the file edit read cache to 16 MB instead of pinning up to 1,000 full files
Reduced session transcript size (up to 79x in edit-heavy sessions) and bounded checkpoint disk usage by pruning superseded file-history backups
Reduced memory usage when resuming sessions with background agents or forks spawned from large conversations
Completed background agents now stay listed in `/tasks` until cleanup instead of vanishing the moment they finish
Attaching to a stopped background agent now shows its transcript immediately while the session warms up, instead of a blank "Session is starting" screen
Background sessions: an older daemon no longer silently restarts workers spawned by a newer version onto the older binary
Agent view: Ctrl+X now deletes renamed-branch worktrees, never destroys unpushed commits, keeps the session row when a worktree is kept, and reused worktree names reset to the current base
Catastrophic removals (e.g. `rm -rf ~`) in commands containing `$(…)`/backticks/`<(…)` now prompt in `--dangerously-skip-permissions` and auto mode, matching the plain form
`/install-github-app` and the `/mcp` settings menu no longer open in background sessions
MCP servers configured with an empty URL now show as "not configured" in `/mcp` instead of a config error
`/usage` now shows your last-known usage bars with an "as of" note when the usage endpoint is rate-limited, instead of an error screen
Fixed Bedrock auth failing with "Session token not found or invalid" for AWS SSO profiles whose sso_region differs from the Bedrock region (2.1.207 regression)

new tool DeferredToolPlaceholder
ScheduleWakeup description updated

fable-5[1m] axis: system prompt +58 chars

Changelog:

Auto mode is now available without `CLAUDE_CODE_ENABLE_AUTO_MODE` opt-in on Bedrock, Vertex AI, and Foundry; disable via `disableAutoMode` in settings
Fixed the terminal freezing and keystrokes lagging while streaming responses containing very long lists, tables, paragraphs, or code blocks
Fixed remote managed settings from a non-interactive run (`claude -p`, the SDK) being permanently recorded as consented without ever showing the security consent dialog
Fixed spurious prompt-injection warnings triggered by benign system-generated conversation updates
Fixed the auto-updater overwriting a custom launcher script or symlink at `~/.local/bin/claude` on every release; `/doctor` now reports an externally managed launcher
Fixed compound commands with `cd` prompting for permission when the only output redirect was to `/dev/null`
Fixed the transcript jumping above the start of the answer when a response finishes streaming
Fixed `extensions.worktreeConfig` being left in the repo's `.git/config` (breaking go-git tools like `tea`) after the last `worktree.sparsePaths` worktree was removed
Fixed malformed bracket patterns in rules globs, skill paths, `.ignore`, and `.worktreeinclude` breaking file reads, file suggestions, and worktree creation
Fixed a crash loop in agent teams where a malformed teammate mailbox message caused repeated errors every second until the mailbox file was manually deleted
Fixed background sessions auto-named by accepting a plan not showing that name on their agent-view row
Fixed background sessions that entered a git worktree resuming blank after a cold reopen from the agent list
Fixed Remote Control task status updates being lost when the connection recovered from a network interruption or credential refresh
Fixed Remote Control sessions hosted by the desktop app not showing background agent and workflow progress on mobile and web
Fixed Deep research runs labeling every Fetch-phase agent "unknown" — chips now show the source hostname
Fixed Bedrock repeatedly requesting fresh AWS SSO credentials from IAM Identity Center on every API request
Improved agent view: pasting the same text again now expands the collapsed `[Pasted text #N]` placeholder instead of adding a second one
Improved agent view: blocked session peeks now lead with the question and show a worded staleness clock (`waiting 3m`) instead of the same timestamp twice
Changed Bedrock, Vertex, and Claude Platform on AWS to default to Claude Opus 4.8
Changed auto mode to no longer read `autoMode` from `.claude/settings.local.json` (repo-resident); use `~/.claude/settings.json` instead
Fixed an indefinite hang on Windows when AWS credential resolution stalls (e.g. a stuck `credential_process`): the 60-second stall guard now fires instead of waiting forever.
Plugin hooks/monitors/MCP headersHelper: `${user_config.*}` in shell-form commands is now rejected (shell-injection fix). Hooks: use exec form (`args` array) or `$CLAUDE_PLUGIN_OPTION_<KEY>`; monitors and headersHelper: read the value inside the script (config file or the server's `env` block).
Plugin option values (`pluginConfigs`) are no longer read from project-level `.claude/settings.json`; only user, `--settings`, and managed settings are honored
Fixed `/usage-credits` amount inputs silently stripping malformed values (e.g. a pasted timestamp) to digits; malformed amounts are now rejected with an error, and amounts over $1,000 require a typed confirmation

Changelog:

Added directory path suggestions to `/cd`, matching `/add-dir` behavior
Added a `/doctor` check that proposes trimming checked-in `CLAUDE.md` files by cutting content Claude could derive from the codebase
`/commit-push-pr` now auto-allows `git push` to the repo's configured push remote (`remote.pushDefault`, or the sole remote when only one is configured) in addition to `origin`
Gateway: `/login` now supports Anthropic-operated public gateway endpoints
`EnterWorktree` now asks for confirmation before entering a git worktree outside the project's `.claude/worktrees/` directory
Background agents now upgrade to a new version in the background right after a Claude Code update, instead of paying a slow stale-session upgrade when you attach
Fixed an expired login failing every model with a misleading "There's an issue with the selected model" error instead of prompting to run `/login`
Fixed `claude --resume` and `--continue` not responding to keyboard input on startup
Fixed MCP servers configured via `--mcp-config` or `.mcp.json` ignoring a per-server `request_timeout_ms`, which caused long-running MCP tool calls to time out at the 60s default in fresh sessions
Fixed `CLAUDE_CODE_EXTRA_BODY` being silently ignored by `claude agents` / `--bg` background workers; the shell-exported override now follows the dispatching session
Fixed OAuth MCP servers requiring manual re-authentication after a single failed token refresh
Fixed `--permission-prompt-tool` pointing at an MCP server crashing with "MCP tool not found" on cold start before the server finishes connecting
Fixed `/model` picker rows printing a price for a different model than the row named, and stopped quoting first-party list prices on providers that don't bill them
Fixed server-provided model rows being misplaced in the `/model` picker when an entitlement or allowlist restriction drops the row they were positioned against
Fixed desktop sessions getting stuck showing "running" after a slash command was sent mid-turn
Fixed keyboard input being ignored in the agents view when a setup prompt appeared before a bare `claude --resume` on Windows
Fixed `claude rm` leaving the removed job in the daemon roster, causing the row to reappear in `claude agents`
Fixed `/remote-control` showing "Unknown command" when logged out — it now explains how to sign in
Fixed left arrow not stepping back out of a phase or agent in the workflow detail view
Fixed `/status` listing the same broken-install warning twice
Fixed false "disused plugin" tips and skewed disuse telemetry for LSP plugins
Fixed `/doctor`'s update check to compare Homebrew installs against their cask's channel instead of the settings channel
Fixed the fullscreen jump-to-bottom pill suggesting Ctrl+End on macOS, not showing rebound chords, and wrapping over the transcript
Bedrock: fixed a multi-minute startup hang when using an `awsCredentialExport` helper on networks with restricted egress
Improved `/code-review` findings quality on claude-opus-4-8 across all effort levels
Improved agents view: status column now uses full terminal width instead of truncating at 64 characters
Changed agents view: Ctrl+X now permanently removes a completed session, and sessions no longer render twice; deleted background jobs stay deleted

Changelog:

Added an auto mode rule that blocks tampering with session transcript files
Fixed `--json-schema` silently producing unstructured output when the schema was invalid, and schemas using the `format` keyword being rejected
Fixed a message sent while Claude was working being silently lost when the turn ended at the `--max-turns` limit
Fixed Windows worktree removal deleting files outside the worktree when an NTFS junction or directory symlink existed inside it
Fixed background agents staying shown as "failed" or "completed" in the agent list after being resumed with `SendMessage`
Fixed background jobs flipping from "needs input" back to "working" in the agent list when the agent's turn contained no readable text
Fixed `claude attach` erroring when a background agent was mid-upgrade restart instead of waiting for it to come back
Fixed session-to-PR linking missing a PR created in a Bash call whose output exceeded the 30K inline limit
Fixed `claude mcp add-from-claude-desktop` getting stuck when a server name contains unsupported characters; invalid names are now reported and remaining servers still import
Fixed a plugin LSP server that fails to initialize preventing a valid LSP server from another plugin handling the same file extension
Fixed a Windows crash when the directory Claude was launched from is deleted, locked, or unmounted while a command is running
Fixed a crash when a file watcher was closed while a directory scan was still in flight
Fixed project verify skills being rewritten on every session instead of only when a documented command changed
Fixed the agent view rendering one line too high and clipping its header when the job list slightly overflowed the screen
Fixed background tasks in the web and mobile Remote Control panels showing stale "Running" status by forwarding full task state on every membership change
Improved auto mode to ask before running `rm -rf` on a variable it can't resolve from context
Auto-update binary downloads now stream to disk instead of buffering in memory, cutting the updater's peak memory usage by roughly 400 MB
Background task notifications now explicitly state that no human input has occurred, preventing fabricated in-transcript approvals from being acted on
Improved agent view: sessions that edit, merge, comment on, or push to an existing PR now link it in `claude agents`
Improved agent view: rows now show a colored state word and a classifier-written headline instead of raw tool call text, and the peek opens with full status including the exact ask for blocked sessions
`/doctor` is now a full setup checkup that can diagnose and fix issues; `/checkup` is its alias
Reserved the "Claude Browser" MCP server name (alongside "Claude Preview") ahead of the Claude Desktop pane rename; user-configured MCP servers can no longer register under either name
Fixed Cowork VM-mode local-agent sessions failing to start with "Not logged in · Please run /login" on CLI 2.1.203+

Skill description updated

sonnet-5 axis: +beta mid-conversation-system-2026-04-07; injected context changed

Changelog:

Added a warning when your login is about to expire, so you can re-authenticate before background sessions are interrupted
Added a grey ⏸ badge to the footer when in manual permission mode, making the active mode always visible
Added the session's additional working directories to MCP `roots/list`, with `notifications/roots/list_changed` sent when the set changes
Fixed opening or switching background agent sessions on macOS stalling for 15–20 seconds due to a false low-memory detection (regression in 2.1.196)
Fixed background sessions becoming permanently unresponsive to attach, replies, and stop when the daemon's session token went stale — the session now recovers automatically
Fixed returning to `claude agents` silently stopping running subagents and re-running the prompt from scratch — their work now carries over
Fixed a memory and per-turn CPU regression in interactive sessions: the context-usage indicator no longer re-analyzes the entire transcript after every turn
Fixed background agents inheriting a stale `PATH` from the daemon instead of the dispatching shell, causing missing tools on Windows
Fixed background and agent-view sessions dropping a shell-exported `ANTHROPIC_BASE_URL`, which sent API keys to the default endpoint and failed with 401
Fixed Bash failing with "argument list too long" in repos with many git worktrees
Fixed worktree-isolated subagents sometimes running shell commands in the parent checkout instead of their own worktree
Fixed worktree creation rejecting nested repositories in multi-repo workspaces, leaving background sessions unable to isolate and edit
Fixed background agents crash-looping when their working directory was deleted, replaced by a file, or became an invalid path — they now fail once with a clear error
Fixed a background daemon auto-upgrade failure silently killing all running background sessions
Fixed `TaskStop` and `TaskOutput` failing to find background agents spawned by another agent — errors now list running agents by id and description
Fixed the `claude agents` composer discarding your typed message when a slash command isn't available there
Fixed the agent list crashing when opening a stopped session whose conversation was already open in another session
Fixed background sessions showing "Needs input" in the agent list after the question was already answered
Fixed background agent startup failures showing only "exit_with_message" instead of the actual error
Fixed background sessions ignoring `effortLevel` changes in settings.json when forked through the daemon
Fixed attached background sessions ignoring `CLAUDE_CODE_DISABLE_MOUSE` and `CLAUDE_CODE_DISABLE_MOUSE_CLICKS` opt-outs
Fixed `/exit` incorrectly warning about running background agents after all named agents had completed
Fixed background sessions started from a non-git directory unable to edit files when a `WorktreeCreate` hook was configured
Fixed the `@` directory picker in `claude agents` not showing registered git worktrees
Fixed background task output on Windows being permanently replaced by an empty file after `/clear`
Fixed content jumping when scrolling up through long transcript history
Fixed the terminal flickering and jumping while typing in bash mode when a shell-history suggestion was shown
Fixed literal `^[[I` / `^[[O` escape codes being printed when reattaching to a background session
Fixed LSP-only plugins being incorrectly flagged for disuse when their language servers deliver diagnostics or answer navigation requests
Improved responsiveness while long responses stream: live-preview updates no longer re-render the whole screen
Improved subagent behavior: agents are now less likely to re-delegate their entire task to another subagent
Reduced binary size by ~7 MB and startup memory by ~7 MB by loading a large bundled dependency lazily instead of inlining it
Changed left arrow to no longer close the background tasks, diff, and workflow detail views — press Esc instead
Changed the empty `claude agents` view to always show the organized sections (Needs input / Working / Completed) with descriptions
Removed the startup "claude command missing or broken" warnings — they now appear in `/doctor` and `/status` instead
Removed a redundant navigation hint from the `claude agents` footer
[VSCode] Added a Settings toggle for "Enable Remote Control for all sessions"

ScheduleWakeup description updated

Changelog:

Added a "Dynamic workflow size" setting in `/config` for controlling how large Claude generally makes dynamic workflows (small/medium/large agent counts) — an advisory guideline, not an enforced cap
Added `workflow.run_id` and `workflow.name` OpenTelemetry attributes to telemetry emitted by workflow-spawned agents, so a workflow run's activity can be reconstructed from OTel data
Fixed a crash in the inline Ctrl+R history search when accepting or cancelling while the search was still scanning the history file
Fixed `/rename` on background sessions being reverted when the job restarts, which broke addressing the session by its new name
Fixed transient mTLS handshake failures when settings were re-applied during an in-place client certificate rotation
Fixed commands sent from Remote Control (mobile/web) into an interactive session failing with "Unknown command"
Fixed images and files sent from the Remote Control mobile or web app without a caption being silently dropped
Fixed the sign-in URL printed by `claude auth login` and `claude mcp login --no-browser` not being reliably clickable when it wraps over SSH — it is now emitted as a single hyperlink
Fixed opening a chat from `claude agents` sometimes failing with "currently running as a background agent" followed by a worker crash/respawn loop
Fixed workflow scripts with unicode quote escapes in strings being corrupted before parsing; workflow parse errors now show the offending line instead of always blaming TypeScript
Fixed voice dictation retrying in an unbounded loop when the microphone or audio recorder fails — repeated capture failures now pause voice input
Fixed `/remote-control` sessions showing the wrong permission mode in the mobile and web apps
Fixed resuming a session by name, or opening the resume picker, taking minutes and using a large amount of memory in repositories with many git worktrees
Fixed installer and updater downloads failing immediately with "aborted" when a proxy or network drops the connection mid-download — transient connection drops now retry
Fixed re-invoking an already-loaded skill appending a duplicate copy of its instructions to context
Improved `/workflows` agent list layout: wider titles, a dedicated time column, shorter model names, and no per-row tool-call counts
Improved MCP error messages: clearer error when a server config has `url` but no `type`, suggesting `"type": "http"` instead of the misleading "command: expected string"
Changed `/review <pr>` back to a fast single-pass review; use `/code-review <level> <pr#>` for the multi-agent review at a chosen effort level
