Claude Code 2.1.247

Rapidly navigating interactive menus no longer triggers the wrong item due to timing latency. Previously, typing a rapid sequence of arrow keys and Enter in history search, /config, /mcp, /skills, background tasks, or /model could accidentally act on the row directly above your target; input event processing is now fixed to reliably target your current selection.

Sub-agents no longer crash outright when their initial API call encounters a 404 model not found error.

Instead, they now transition smoothly through the session's fallback model chain, and if the operation still fails, the error sent back to the parent agent includes the error type, status, request id, and model name.

Hooks or background agents that dump megabytes of error output can no longer flood the conversation history and wedge the session on "Prompt is too long". The system now prevents excessive diagnostic output from overwhelming the context window, keeping your terminal responsive.

Using Ctrl keyboard shortcuts in terminals supporting the kitty keyboard protocol now works reliably under non-Latin keyboard layouts such as Cyrillic. Previously, switching input layouts prevented modifier key combinations from firing; keyboard event translation is now fixed across all keyboard configurations.

Mouse tracking reports that arrive split across stream reads directly after an escape prefix will no longer dump stray text fragments like <35;150;7M straight into your prompt input.

Input stream buffering now properly reconstructs split control sequences.

Users managing dotfiles with tools like nix/home-manager or GNU stow no longer risk having their configuration link erased. Previously, when the Bash sandbox cleaned up after running a command, if the ~/.claude/settings.json symlink was repointed outside the sandbox's writable area, the cleanup routine deleted the symlink; the sandbox now safely preserves these links.

Running /terminal-setup to configure keybindings for the Zed editor no longer wipes out your entire keymap configuration.

Instead of completely overwriting keymap.json, the command now cleanly merges its required keybindings into your existing file, preserving all your personal custom shortcuts.

When running /rename to rename your session, the interface no longer gives a silent confirmation if the session registry cannot be updated. It now explicitly alerts you that other sessions might still display the old name, ensuring you are aware of the registry state.

Sessions launched with --agent now maintain their custom system prompt during context compaction. Previously, running /compact or using "Summarize from here" caused the summary to be generated under the generic default system prompt; it now strictly preserves the conversation's own prompt instructions.

In the claude agents list, background sessions whose terminal host process died will no longer remain stuck displaying "opening…" forever.

The row now marks itself as failed within seconds along with the failure reason, and pressing Enter immediately restarts the session.

If a hook or background task cannot write to its output file, the system no longer buffers the data indefinitely in memory, preventing unbounded memory growth. Additionally, the log file now records an explicit note indicating where output was lost.

Running /install-github-app over an SSH connection now handles clipboard and browser limitations gracefully. The copy shortcut explicitly reports how the sign-in URL was copied rather than falsely claiming universal success, and if no browser can be opened remotely, the URL prints immediately to the screen.

Shell commands handed off from the foreground to background sessions no longer log internal errors or display a misleading [exited with code -1] banner upon completion.

Background task status is now reported cleanly upon normal termination.

Installing a version-less marketplace plugin across a second scope no longer purges and recreates its active cache directory. This eliminates the risk of disrupting existing, active sessions that are currently executing the plugin.

Remote Control sessions launched via /remote-control now reliably broadcast the working-tree diff to connected clients.

Previously, attached clients could not see pending file modifications; this sync issue is resolved so remote collaborators see current changes in real time.

Self-hosted runner sessions no longer report a "running" status before Claude Code has actually booted up. This eliminates premature "Claude is waiting for your input" notifications fired by the Claude desktop app while initialization is still underway.

First-run setup no longer abruptly aborts with "Unable to connect to Anthropic services" when managed settings configure gateway sign-in for Claude apps while standard Anthropic endpoints are blocked.

Initial configuration proceeds smoothly over the designated gateway channel.

In cloud sessions across web, desktop, and mobile apps, rapidly toggling your permission mode right after dispatching a message no longer causes the UI to flicker back to the prior mode. State synchronization now ensures your updated mode remains active regardless of network transmission timing.

If a cloud session's container restarts between turns while background agents, shells, or monitors are active, the resumed session no longer silently drops into limbo. It now explicitly reports any lost work and background processes that were interrupted.
