Session titles are now generated in the language of your conversation (set the language setting to pin a specific language)

Added footerLinksRegexes setting for regex-matched link badges in the footer row, configurable via user or managed settings

Improved Bedrock credential caching: credentials from awsCredentialExport are now cached until their Expiration instead of a fixed 1 hour

Fixed availableModels enforcement: alias model picks can no longer be redirected to a blocked model via ANTHROPIC_DEFAULT_*_MODEL environment variables, and /fast now refuses to toggle when it would switch to a model outside the allowlist

Fixed auto mode failing on Fable 5 for organizations without Opus 4.8 enabled — the classifier now falls back to the best available Opus model

Fixed hook if conditions for Read/Edit/Write tool paths: documented patterns like Edit(src/**), Read(~/.ssh/**), and Read(.env) now match correctly

Fixed Linux sandbox failing to start when .claude/settings.json is a symlink with an absolute target

Fixed /copy and mouse-selection copy not reaching the system clipboard inside tmux over SSH, and tmux paste buffer not loading on versions older than 3.2

Fixed Remote Control connecting from web/mobile silently switching the session's model

Fixed Remote Control disconnect notifications showing a bare numeric code instead of a human-readable reason, and connection failures adding a duplicate line to the conversation transcript

Fixed Remote Control sessions not disconnecting when you sign in to a different account

Fixed /cd and worktree moves leaving the session reporting the previous directory's git branch

Fixed claude agents: pressing back in one window no longer detaches other windows attached to the same session

Fixed backgrounded sessions showing "Working" forever when /bg mid-turn had nothing left to continue

Fixed background agent search by PR URL: PRs opened during scheduled wakeups or while a job was blocked now appear in claude agents search

Fixed the agents view input showing no text cursor on Windows

Fixed claude --bg -cn <name> not seeding the session name

Fixed background sessions to neutralize Windows network paths in persisted state before respawn

Fixed background-session respawn rejecting malformed resume IDs from corrupted state files

Fixed the Windows background-service daemon not starting when ~/.claude/daemon has the ReadOnly attribute set

Fixed cloud sessions failing with "Could not resolve authentication method" when idle for too long before being claimed

Background sessions now show clearer guidance when a window left open across an auto-update can't submit a reply, and claude daemon status explains version-skew behavior

]]> https://code.claude.com/docs/en/changelog#2-1-175 d3cda952ba4d3b16 Fri, 12 Jun 2026 07:35:58 GMT

Added enforceAvailableModels managed setting — when enabled, the availableModels allowlist also constrains the Default model (a Default that would resolve to a disallowed model now falls back to the first allowed model), and user or project settings can no longer widen a managed availableModels list

]]> https://code.claude.com/docs/en/changelog#2-1-174 e393946c862fb92e Fri, 12 Jun 2026 07:35:58 GMT

Added wheelScrollAccelerationEnabled setting to disable mouse-wheel scroll acceleration in fullscreen mode

Fixed the /model picker hiding the model family that Default resolves to — Opus now appears as its own row on Max/Team Premium/Enterprise plans, Sonnet on Pro/Team plans, and Opus on pay-as-you-go API accounts

Fixed /model picker showing a hardcoded Sonnet version label when ANTHROPIC_DEFAULT_SONNET_MODEL pins a different Sonnet

Fixed the "Fable 5 is now consuming usage credits" banner incorrectly showing for enterprise accounts with usage-based billing

Fixed Bedrock GovCloud regions (us-gov-*) deriving the wrong inference profile prefix (global instead of us-gov), causing 400 errors on derived model IDs

Fixed background sessions inheriting another session's ANTHROPIC_* provider env (gateway URL, custom headers, /model aliases) from the shell that started the background daemon

Fixed a 1-2 second pause when exiting Claude Code shortly after a shell command was interrupted or killed on macOS and Linux

Fixed git commit co-author attribution showing an incorrect model name for some models

Fixed the /advisor dialog pre-selecting a saved advisor model that is blocked by the availableModels allowlist

Fixed skill hot-reload re-sending the entire skill listing when a single skill changed; only changed skills are now re-announced

Fixed Workflow tool agent() subagents missing per-agent attribution headers

[VSCode] Added usage attribution to the Account & usage dialog (/usage) showing cache misses, long context, subagents, and per-skill/agent/plugin/MCP breakdowns over the last 24h or 7d

Fixed pre-warmed background workers failing with "Could not resolve authentication method" when claimed after sitting idle

]]> https://code.claude.com/docs/en/changelog#2-1-173 d9947d2897673d99 Thu, 11 Jun 2026 07:39:31 GMT

Fixed Fable 5 model names with a [1m] suffix not being normalized — Fable 5 includes 1M context by default, so the suffix is now stripped automatically

Fixed a spurious "sandbox dependencies missing" startup warning on Windows when sandbox was enabled in settings

]]> https://code.claude.com/docs/en/changelog#2-1-172 8ab4e5b8feb3e530 Thu, 11 Jun 2026 00:39:33 GMT

Sub-agents can now spawn their own sub-agents (up to 5 levels deep)

Amazon Bedrock now reads the AWS region from ~/.aws config files when AWS_REGION isn't set, matching AWS SDK precedence; /status shows where the region came from

Added a search bar when browsing a marketplace's plugins in /plugin

Added model attribute to the claude_code.lines_of_code.count OTEL metric

Fixed sessions using 1M context without usage credits getting permanently stuck — the session now automatically compacts back under the standard context limit

Fixed a repeating "an image in the conversation could not be processed and was removed" error when the conversation contained multiple images

Fixed the agents view keeping a session under Working with a busy spinner for up to 30 seconds after the worker replied

Fixed background agents potentially reading another directory's project settings (.mcp.json approvals, trust) when dispatched onto a pre-warmed worker

Fixed background-session attach failing with EAUTH for sessions started on an older version after the daemon auto-updated

Fixed a background sub-agent staying stuck as "active" in the agent panel after a nested agent it spawned was stopped

Fixed /model suggestions in the claude agents dispatch input rendering with a misleading slash prefix and showing models disabled for your org

Fixed availableModels restrictions not being applied to subagent model overrides, the agent dispatch model picker, and the advisor model

Fixed availableModels allowlists hiding the /model picker's Opus and Sonnet 1M rows when entries use version-specific IDs like claude-opus-4-8

Fixed the /model picker on Bedrock offering models the provider doesn't serve — selecting one silently switched the session model and lit the selection marker on multiple rows

Fixed model IDs getting a doubled 1M-context suffix (e.g. [1M][1m]) when ANTHROPIC_DEFAULT_OPUS_MODEL already includes one

Fixed opusplan model setting not shipping with 1M context in plan mode for entitled users; the opusplan[1m] workaround now also correctly switches to Opus in plan mode

Fixed WebFetch(domain:*.example.com) wildcard domain rules never matching subdomains in allow, deny, and ask position, and file permission rules with mid-pattern wildcards (e.g. Read(secrets-*/config.json)) being rejected at startup

Fixed up-arrow prompt history showing the main agent's prompts while a subagent's chat tab is open

Improved performance in long conversations by removing redundant message normalization and avoiding full message-history transforms when streaming tool-use state is unchanged

Reduced idle CPU usage: /goal status chip no longer re-renders the terminal at 5 Hz while idle, and fewer UI re-renders while subagents run in parallel

Improved Claude in Chrome tool loading: browser tools now load in a single batched call instead of one per tool

Improved the non-interactive Usage Policy refusal message to suggest starting a new session or changing your model

/code-review now keeps the ultra option visible when you're not signed in to claude.ai, with an explanation that the cloud review requires a claude.ai account

Shortened the Remote Control footer indicator to "/rc active" and hid it on narrow terminals

Stopped promoting /loop in remote sessions, where pending loops don't keep the container alive

[VSCode] Fixed PowerShell tool calls rendering as raw JSON instead of a proper command display and permission dialog, and stripped ANSI escape codes from displayed shell output

Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Fable’s capabilities exceed those of any model we’ve ever made generally available. Update to version 2.1.170 for access. https://www.anthropic.com/news/claude-fable-5-mythos-5

Fixed sessions not saving transcripts (and not appearing in --resume) when launched from the VS Code integrated terminal or any shell that inherited Claude Code environment variables.

]]> https://code.claude.com/docs/en/changelog#2-1-169 b6d5ada4604ad6d1 Mon, 08 Jun 2026 22:04:09 GMT

Self-hosted runner: added a post-session lifecycle hook that runs after the session ends and before the workspace is deleted, so you can snapshot uncommitted work or export logs; also made the child-process SIGTERM→SIGKILL window configurable (default unchanged at 5s)

Added --safe-mode flag (and CLAUDE_CODE_SAFE_MODE) to start Claude Code with all customizations (CLAUDE.md, plugins, skills, hooks, MCP servers) disabled for troubleshooting

Added /cd command to move a session to a new working directory without breaking the prompt cache mid-session

Added a disableBundledSkills setting and CLAUDE_CODE_DISABLE_BUNDLED_SKILLS environment variable to hide bundled skills, workflows, and built-in slash commands from the model

Fixed Up/Down arrows jumping to command history past the wrapped rows of a long input line — they now move through each visual row first, and history recall enters at the near edge

Fixed enterprise managed MCP policies (allowedMcpServers/deniedMcpServers) not being enforced on reconnect, IDE-typed configs, --mcp-config servers during the first session after install, or before remote settings loaded; also fixed slow cold starts for orgs without remote settings

Fixed a ~30-50ms UI stall at the start of each turn for macOS users logged in with claude.ai credentials

Fixed claude -p being slow or appearing to hang on Windows while waiting for the slash-command/skill scan (regression in 2.1.161)

Fixed Remote Control getting stuck on "reconnecting" after resuming a session when an OAuth token refresh happened at the same time

Fixed Git Credential Manager's "Connect to GitHub" popup appearing on Windows at startup when background git commands ran without cached credentials

Fixed footer hints (e.g. "esc to interrupt") not showing for users with a custom statusline

Fixed stale permission and dialog prompts reappearing every time you reattached to a remote session whose worker had died while waiting on them

Fixed claude agents --json omitting blocked and just-dispatched background sessions; added --all to include completed sessions, plus new id and state fields

Fixed agents view leaving a stale/garbled frame after navigating back from an agent on WSL in Windows Terminal

Fixed background agents ignoring project-level settings env values (e.g. ANTHROPIC_MODEL) when dispatched onto a pre-warmed worker

Fixed MCPB plugin cache being spuriously invalidated on Windows, causing unnecessary re-extraction

Fixed plugin .in_use PID lock files accumulating without bound; stale markers from crashed sessions are now swept once per day

Fixed untrusted project settings being able to set OTEL client-certificate paths without trust confirmation

/workflows now opens immediately even while a turn is in progress

Improved TaskCreate reliability: malformed inputs are repaired automatically and validation errors for unloaded tools include the schema

Improved the error message shown when your organization has disabled API key authentication, with guidance based on where the active API key comes from

Reduced CPU usage while responses stream and during spinner animations

Restored a default 5-minute idle timeout on Vertex/Foundry so a stalled stream aborts instead of hanging indefinitely; set API_FORCE_IDLE_TIMEOUT=0 to opt out

Remote-managed settings with an invalid entry now apply their remaining valid policies and surface the validation error, instead of silently dropping the whole payload

Background sessions now preserve --ide, --chrome, --bare, --remote-control, and other flags across retire→wake, and respawn state validation was hardened

Background sessions are now told that shared-checkout edits are blocked until they enter a worktree, avoiding a wasted rejected edit before EnterWorktree

The "CLAUDE.md is too long" warning threshold now scales with the model's context window

Auto-updater on Windows now stops retrying within a session once claude.exe is held by another process

Improved color contrast for skill tags in the slash-command menu

Promo credit claims for Apple/Google-billed subscribers without a payment method now explain where to add one

Added a tip suggesting claude agents when running multiple concurrent sessions

Added fallbackModel setting to configure up to three fallback models tried in order when the primary model is overloaded or unavailable; --fallback-model now also applies to interactive sessions

Added glob pattern support in deny rule tool-name position ("*" denies all tools); allow rules reject non-MCP globs, and unknown tool names in deny rules warn at startup

Hardened cross-session messaging: messages relayed via SendMessage from other Claude sessions no longer carry user authority — receivers refuse relayed permission requests, and auto mode blocks them

MAX_THINKING_TOKENS=0, --thinking disabled, and the per-model thinking toggle now disable thinking on models that think by default via the Claude API (3P providers unchanged)

Claude Code now retries a turn once on the fallback model when the API rejects an unexpected non-retryable error; auth, rate-limit, request-size, and transport errors still surface immediately

claude update now announces the target version before downloading instead of going silent

claude agents: typing a URL into the list now filters to the session whose first prompt contained it

Fixed a recurring "image could not be processed" error and extra token usage when an unprocessable image was sent in a session

Fixed remote sessions becoming permanently stuck when a brief backend disruption occurred during worker registration at startup

Fixed flickering in JetBrains IDE terminals (IntelliJ, PyCharm, WebStorm, etc.) on 2026.1+ by enabling synchronized output

Fixed Shift+non-ASCII characters (e.g. Shift+ä → Ä) being dropped in terminals using the Kitty keyboard protocol (WezTerm, Ghostty, kitty)

Fixed PowerShell command validation occasionally hanging far past its time budget on Windows when a killed process's children held its output pipes

Fixed orphaned claude --bg-pty-host processes spinning at 100% CPU after the daemon dies while connected on macOS

Fixed voice mode requiring /login to clear a stale auth check after toggling /voice

Fixed managed settings with an invalid entry silently disabling enforcement of their remaining valid policies

Fixed managed-settings allowedMcpServers/deniedMcpServers predicates not matching when they use ${VAR} references

Fixed background agent sessions that entered a git worktree crash-looping with "No conversation found" when reopened from claude agents

Fixed duplicated thinking text in the Ctrl+O transcript view while streaming

Fixed /doctor showing a contradictory failed "Not inside a remote session" check when run inside a remote session

Fixed the cursor sticking at the end of the first line when typing a multiline prompt in the claude agents dispatch and reply inputs

Fixed blank lines appearing between background agent rows in the task list on terminals without Unicode support

Added requiredMinimumVersion and requiredMaximumVersion managed settings — Claude Code refuses to start if its version is outside the allowed range and directs the user to an approved version

Added /plugin list command to list installed plugins, with --enabled/--disabled filters

Added a "c to copy" shortcut to /btw that copies the raw markdown answer to the clipboard, preserving formatting when pasted elsewhere

Hooks: Stop and SubagentStop hooks can now return hookSpecificOutput.additionalContext to give Claude feedback and keep the turn going without being labeled a hook error

Skills: added \$ escape syntax to include a literal $ before a digit in command bodies

stdio MCP servers now receive the same CLAUDE_CODE_SESSION_ID as hooks/Bash on --resume

Fixed claude -p hanging forever after its final result when a backgrounded command never exits — background shells are now stopped ~5s after the result once stdin closes

Fixed claude -p failing with "ANTHROPIC_API_KEY required" on Bedrock/Vertex/Foundry when CI=true and no Anthropic API key is set

Fixed bash commands failing under bazel and EDR-protected Go workflows: $TMPDIR was overridden to /tmp/claude-{uid} for all commands instead of only sandboxed ones (regression in 2.1.154)

Fixed Bash commands failing on Windows with "EEXIST: file already exists" on the session-env directory when it has the read-only attribute or is inside OneDrive

Fixed org-managed permission rules not applying for the entire session when the managed settings fetch completed during startup on a fresh config directory

Fixed background sessions in claude agents losing their running background tasks when reattached after a Claude Code update

Fixed terminal misalignment and a multi-second hang when exiting the agent view by pressing Esc

Fixed clicking Stop on a background-task chip in the desktop app not clearing the chip when the underlying process was already gone

Fixed keyboard input becoming permanently unresponsive after a paste operation whose end marker is dropped by the terminal

Fixed hook if: "Bash(...)" conditions firing on every Bash command containing $() or $VAR; the pattern now matches against commands inside subshells and backticks too

Fixed deny rules on home-directory paths (e.g. Read(~/Desktop/**)) not blocking Bash commands that reference the path via $HOME

Fixed a stray "(no content)" line left in the transcript after closing panel dialogs like /mcp and /plugins

Background agent sessions now update to a new Claude Code version in the background, so opening a session after an update no longer waits on a cold restart

Clearer descriptions for built-in commands and skills in the / menu

The subscription-switch suggestion now shows in the startup announcement slot instead of a toast

claude agents dispatching from the state-grouped view now starts the session in the directory the agent view was opened from

claude agents --json now includes waitingFor showing what a waiting session is blocked on (e.g. permission prompt)

--tools: explicitly listing Grep/Glob now provides the dedicated search tools on native builds with embedded search (previously these names were silently ignored)

/effort now confirms when your chosen level will persist as the default for new sessions

Clicking a slash command in the autocomplete menu now fills it into your prompt instead of running it immediately; press Enter to run

Remote Control now shows as a persistent footer pill (with a link to the session) instead of a startup message

Renamed Windsurf to Devin Desktop in the /ide menu, /terminal-setup, and /scroll-speed, following the editor's rebrand

Fixed a silent startup hang when the config directory is read-only or unwritable — Claude Code now starts with in-memory config and surfaces startup errors instead of showing a blank screen

Fixed WebFetch permission rules not being applied to built-in preapproved domains; explicit WebFetch(domain:...) deny/ask/allow rules now take precedence over the preapproved-host auto-allow

Fixed Windows permission rules never matching when spelled with backslashes (~\, \\server\share) or case-variant paths, and Read deny rules not hiding files from Glob/Grep results

Fixed an interrupt (Esc) sent at the very start of a turn being silently dropped in stream-json/SDK sessions, leaving the turn running with no "Interrupted" feedback

Fixed API 400 no low surrogate in string errors for classifier side-queries and MCP server descriptions containing emoji near a truncation boundary

Fixed MCP per-server timeout config values below 1000 ms being floored to a 1-second watchdog that aborted every tool call; sub-1000 ms values are now ignored (falling back to MCP_TOOL_TIMEOUT or default), and claude mcp get annotates them accordingly

Fixed the LSP tool's workspaceSymbol operation returning no results; it now accepts a query parameter and passes it to the language server

Fixed claude agents cutting live status text (tool args, replies, prompts, exec output) at 60–120 columns on wide terminals; the status detail now uses the full terminal width

Fixed claude agents truncating long session names at 40 columns; the name column now grows with terminal width

Fixed claude agents attach occasionally bouncing straight back to the session list on the first try after a background-service restart

Fixed claude agents Ctrl+V image paste doing nothing in the dispatch input and the session reply box; pasting with no image now shows a hint

Fixed backgrounding a session with ← silently losing the conversation when the background service cannot start; the session stays in the list as a failed row you can wake with Enter

Fixed replies from the agents view that fail to send being lost; they are now queued for delivery on the next session start

Fixed cross-session messaging (SendMessage) silently breaking when CLAUDE_CODE_TMPDIR or $TMPDIR points at a deep directory

Fixed opening a running background session from claude agents stalling for 5 seconds before attaching

Quieter startup: notices group by severity, and session info and announcements share a single line per launch

Startup warnings rewritten to be shorter and clearer, each with a concrete fix

Launch-prompt warnings (deep link/pre-filled prompt) now stay pinned below the input until you act instead of scrolling away

Failed turns now show a compact warning line instead of a multi-line red error block

Improved background service startup and claude update verification to wait out endpoint-security scanning of new binaries instead of failing after 5 seconds

Background dispatch spawn failures now report the error class name when no errno is available

Removed the "Claude in Chrome enabled" and "marketplace installed" startup messages; model auto-updates and the team-onboarding tip now show as quiet notices under the logo

]]> https://code.claude.com/docs/en/changelog#2-1-161 471c2f0cc2c4f1df Tue, 02 Jun 2026 22:08:49 GMT

OTEL_RESOURCE_ATTRIBUTES values are now included as labels on metric datapoints, so you can slice usage metrics by custom dimensions like team or repo

claude agents rows now show done/total before the detail when work is fanned out; peek shows the longest-running item

/mcp now collapses claude.ai connectors you've never signed in to behind a "Show unused connectors" row

Parallel tool calls: a failed Bash command no longer cancels other calls in the same batch — each tool returns its own result independently

Fullscreen mode: clipboard now uses wl-copy/xclip/xsel on Linux when available, copies to both the clipboard and PRIMARY selection for middle-click paste, and the "hold {key} for native selection" hint now shows the correct key per terminal

Fixed the /effort dialog, workflow animations, and prompt keyword shimmer not honoring the "Reduce motion" setting

Fixed forceLoginOrgUUID/forceLoginMethod managed-settings policies blocking third-party provider sessions (Bedrock, Vertex, Foundry, Mantle) alongside the org pin (regression in 2.1.146)

Fixed background subagent output corrupting claude -p stdout when using --output-format text or json

Fixed /usage-credits starting a re-login for Team and Enterprise admins instead of pointing to the organization's usage settings page

Fixed /autofix-pr reporting "cannot run on the default branch" when the session is inside a git worktree or another repository

Fixed --resume picker not showing sessions from the current directory when it isn't a git worktree (e.g., jj workspaces)

Fixed Windows hooks that invoke bash explicitly (e.g., /usr/bin/bash script.sh) failing with "command not found" or "cannot execute binary file"

Fixed OpenTelemetry log events (user_prompt, api_request, tool_result, tool_decision) being silently dropped when emitted before telemetry initialization completed

Fixed claude mcp list/get/add printing secrets to the terminal: ${VAR} references are no longer expanded, and credential headers and URL secrets are redacted

Fixed Workflow agents spawned with isolation: "worktree" in background sessions being blocked from editing files inside their own worktree

Fixed background sessions dispatched from claude agents booting on a stale model from the daemon's environment instead of the model in settings.json

Fixed a potential crash when rendering Write tool results after resuming a session

Fixed completed subagents getting stuck showing as running when an error occurs while finalizing their result

Fixed EADDRINUSE errors from tools that bind Unix sockets under $TMPDIR when CLAUDE_CODE_TMPDIR is set to a deep path

Improved terminal rendering performance by stabilizing the layout engine's JIT compilation profile

Improved rendering performance for large file writes

[VSCode] Added a tip suggesting disabling terminal GPU acceleration (or running /terminal-setup) to fix garbled glyphs

]]> https://code.claude.com/docs/en/changelog#2-1-160 4ffb3b0a6d750b25 Tue, 02 Jun 2026 02:18:10 GMT

Added a prompt before writing to shell startup files (.zshenv, .zlogin, .bash_login) and ~/.config/git/, which could otherwise lead to unintended command execution

acceptEdits mode now prompts before writing build-tool config files that grant code execution (.npmrc, .yarnrc*, bunfig.toml, .bazelrc, .pre-commit-config.yaml, .devcontainer/, etc.)

Edit no longer requires a separate Read after viewing a file with grep: single-file grep/egrep/fgrep commands now satisfy the read-before-edit check

Fixed copy-on-select not writing to the Windows clipboard on WSL — now uses PowerShell interop instead of OSC 52, which terminals like MobaXterm don't support

Fixed restoring a completed session from claude agents dropping chat history and re-running the original prompt

Fixed background sessions re-attached after overnight retire losing their conversation and re-running the original prompt

Fixed claude --bg occasionally failing with "socket missing" when the background daemon was cold-starting on a loaded machine

Fixed an issue on Windows where the directory a background session was started in could not be deleted after claude rm until the background daemon exited

Fixed background agents that resumed work being shown under Completed in the agents list

Fixed claude agents freezing for several seconds when returning to the session list due to the auto-updater re-checking on every exit

Fixed Esc, arrow keys, and typing becoming unresponsive on Windows when attached to a background session or in the agent view while the host is under heavy CPU load

Fixed background agents emitting terminal sync-output markers to terminals that don't support them (Apple Terminal, tmux), causing render artifacts when entering a running agent

Fixed mouse wheel scrolling prompt history instead of the transcript right after opening a session from the agents list

Fixed CJK IME composition appearing at the bottom-left of the screen instead of at the input caret in the claude agents view

Fixed valid file:///C:/... links being rewritten to a broken path on Windows terminals with hyperlink support

Fixed voice mode failing to connect when the project directory or branch name contains non-ASCII or special characters

Fixed the auto mode unavailability message on third-party providers (Bedrock/Vertex/Foundry) to point to the CLAUDE_CODE_ENABLE_AUTO_MODE opt-in instead of incorrectly blaming the model

Fixed /effort ultracode incorrectly blaming the dynamic workflows setting when the model cannot run xhigh; ultracode is no longer offered on models that do not support it

Fixed model-not-found errors suggesting --model when running via the SDK or other hosts where the CLI flag doesn't apply

Fixed Claude's past replies disappearing from scrollback when resuming a brief mode session with brief mode turned off

Fixed vim mode p pasting on the line below instead of at the cursor when the register was yanked with v$

Improved performance of opening recently-inactive background agent sessions in claude agents

Improved auto mode classifier latency by reducing reasoning on routine actions, lowering the chance of "could not evaluate this action" blocks

Improved background-session teardown (claude rm/stop, idle reap) to send SIGTERM to running shell subprocesses before SIGKILL, so cleanup handlers run

Removed CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE; the environment variable is now a no-op

Removed the JetBrains plugin install suggestion from startup

Renamed the dynamic-workflow trigger keyword from workflow to ultracode. The word "workflow" no longer triggers a run; asking for one in your own words still works. The trigger keyword is highlighted in violet in the prompt input
