Claude Code 2.1.221 አውርድ

- [VSCode] Added Focus view: a chat-menu toggle that hides tool activity behind an expandable per-turn summary with a live running-tool indicator, toggled with Ctrl+Alt+F or the "Claude Code: Toggle Focus view" command
- Added mode: "mask" for sandbox credential files on Linux and WSL — sandboxed commands read a sentinel copy (the whole file, or just the spans captured by an extract regex) while the sandbox proxy substitutes the real value on egress; on macOS file masking falls back to deny
- Added warnings to claude plugin validate when a marketplace or plugin name would be rejected by Claude Desktop's managed marketplace sync
- Added a prompt-audit subcommand to the claude-api skill for auditing prompts and tool descriptions for patterns written for older models
- Fixed a Bash tool permission-check bypass where zsh could execute hidden commands in [[ ]] regex conditionals; affected commands now prompt for permission
- Fixed PowerShell permission checks mishandling paths containing quote characters on Windows; such paths now prompt for approval
- Fixed the thinking toggle having no effect for the rest of a session that started with thinking off; disabling an MCP server mid-connect no longer silently reverts
- Fixed MCP servers from --mcp-config not being connected before the first turn in print mode (-p), which made the model emit tool calls as literal text
- Fixed @-mentioned files being silently dropped when pressing Esc to retract a prompt and resubmitting it
- Fixed a crash when preparing API requests for SDK MCP tools named after built-in object properties such as constructor
- Fixed WebSearch failing with a 400 error at effort xhigh/max when thinking is disabled
- Fixed sandboxed large uploads failing with TLS errors through the sandbox proxy
- Fixed Team and Enterprise spend-limit message incorrectly blaming the org's monthly limit instead of your individual spend limit
- Fixed Bedrock authentication with AWS SSO named profiles failing in desktop-managed sessions on Windows machines that set a stray HOME environment variable
- Fixed CLAUDE_CODE_RESUME_INTERRUPTED_TURN=0 not disabling interrupted-turn auto-resume; falsy values are now honored
- Fixed a rare wake-from-sleep race where two Claude Code processes could both refresh the same MCP connector or WIF OAuth token at once, forcing re-authentication
- Fixed renaming a session from Claude Code Desktop or claude.ai not updating the CLI's session name; session names from every rename surface are now sanitized
- Fixed plugin- and org-delivered skills named after terminal-only built-ins (e.g. /help, /feedback) being un-invocable in non-interactive sessions
- Fixed the "Plugins changed" notification lingering after plugins were reloaded instead of clearing
- Fixed Vim mode: the yank register now survives dialogs, history search, and the transcript view instead of being silently emptied
- Fixed Vim mode: undoing back to an empty prompt now arms the "press ← again" confirm before returning to the agent view
- Improved tool search on Google Vertex AI: re-enabled for Claude 4.5-generation and newer models
- Improved auto mode: permission checks for parallel tool calls are now cache-efficient, and switching modes while a check is pending reliably prompts instead of applying the stale result
- Reduced prompt-cache costs for auto-mode permission checks by reusing the cached conversation prefix across decisions
- Improved Stats panel to count cache tokens in its token totals, with a breakdown by input, output, cache read, and cache write
- Improved /ultrareview error messages when a repo shares no history with its base: a checkout with no branches is now refused up front with advice to create one, and refusal hints no longer suggest git fetch --unshallow on clones that are already complete
- Improved Windows startup: process creation times are now read via a native kernel32 call instead of spawning PowerShell, so endpoint security tools that gate powershell.exe no longer prompt
- Changed background sessions to commit and push to preserve work, open a draft PR only when the task calls for one, follow your CLAUDE.md git instructions, and always end by reporting where the work lives
- Changed /plugin install to refresh a stale marketplace catalog and retry before reporting a plugin not found
- Changed plugins installed from /plugin to activate immediately when safe, instead of always requiring /reload-plugins
- Changed plugins to accept "." as a skills path, and the root-level SKILL.md validation error now suggests using the plugin root
- Changed /status to show the session kind: interactive, or a background job that is attached or unattended
- Changed emoji autocomplete to accept common alternate shortcodes like :thumbsup:, :thumbsdown:, and :love:
- Changed sessions forked with /fork to create a new worktree of their own instead of working in the original session's checkout
- Changed Claude in Chrome to close the browser tabs it opens once it no longer needs them
- Changed fast mode to report on the stream when usage credits run out mid-session, instead of failing silently
- Changed Monitor: a watch that exits without producing any output now says so instead of reporting "stream ended"
- Changed the Gateway model field validation: non-string values are rejected with a 400 instead of being forwarded
- Removed the repeated "Permission mode changed while the auto-mode classifier call was queued" notice from approval prompts
