v2.1.246

Bug Fixes

• Fixed fullscreen mode showing a blank transcript after resizing the terminal and jumping to the bottom until the next keypress
• Fixed a severe transcript slowdown when a diff contained a very long single line by truncating and marking such lines
• Fixed erratic fullscreen scrolling when positioned at an earlier message, preventing jump-to-bottom from getting stuck
• Fixed background sessions failing to open after 45 seconds due to deleted directories, machine sleep, or slow process startup
• Fixed background sessions failing to open with an EACCES error when another Claude Code process was re-installing the npm package
• Fixed markdown rendering being disabled for entire messages under specific conditions (no markdown in first 500 chars, or for certain list/heading types)
• Fixed MCP tool calls interrupted by an incoming message in headless/remote sessions being incorrectly reported as completed with no output
• Fixed MCP tool arguments being sent as JSON strings when the parameter's schema is empty, instead of their correct type
• Fixed commands interrupted mid-run showing as completed without indicating they were cut short
• Fixed pressing back arrow or running /background during a dynamic workflow from restarting finished subagents; now prompts for confirmation
• Fixed opening a just-started session in 'claude agents' while its worker was booting from stopping unexpectedly
• Fixed 'claude agents' listing a backgrounded named session twice; now numbers subsequent backgroundings of the same conversation
• Fixed the background retention sweep removing user-created git worktrees under .claude/worktrees/
• Fixed auto mode tool calls being denied on very large sessions by scaling the safety-check deadline with prompt size
• Fixed the plugin cache creating duplicate SHA-named directories for the same plugin
• Fixed plugin skills showing doubled names in the slash menu when the frontmatter 'name' already includes the '<plugin>:' prefix
• Fixed 'claude plugin update' failing for installed plugins given only their bare name
• Fixed plugin installation failing when 'plugin.json' was saved with a UTF-8 byte-order mark (BOM)
• Fixed '/reload-plugins' reporting 0 skills for plugins that define skills under 'skills/*/SKILL.md'
• Fixed hook error messages showing a literal "${CLAUDE_PLUGIN_ROOT}" instead of the resolved plugin path
• Fixed '/rename' replacing the theme's prompt border color with default cyan; border now retains theme color unless overridden
• Fixed custom theme diff colors being ignored in diffs and the '/theme' preview
• Fixed a 'keybindings.json' binding with an unknown action name silently disabling the key; now logs a warning and keeps default binding
• Fixed '/stats' activity heatmap showing days off by one cell in timezones east of UTC
• Fixed '/fork' from an already-forked or backgrounded session starting the new session with an empty conversation
• Fixed the '@' file picker staying open after typed text stopped matching a real path
• Fixed the status line's cost and duration resetting to zero after navigating to the agents view and back
• Fixed fullscreen mode moving keyboard focus unexpectedly when clicking the terminal window
• Fixed path completion failing when the completion token or working directory contained a null byte
• Fixed headless sessions not cleaning up stale entries in '~/.claude/sessions' on Windows/macOS after unclean exits
• Fixed the UI stopping with a render error on the first tool call when a third-party Anthropic-compatible endpoint streams a 'tool_use' block without an 'id'
• Fixed the Write tool reporting 'Out of memory' or freezing after overwriting a very large file
• Fixed 'claude plugin install <name>' exiting silently or hanging when '~/.claude/plugins/known_marketplaces.json' is empty or corrupted
• Fixed resumed sessions failing every turn with a 400 error when saved history contains tool blocks not accepted by the Anthropic API
• Fixed 'curl -fsSL https://claude.ai/install.sh | bash' failing with 'Raw mode is not supported' for some Team/Enterprise users
• Fixed sessions ending in plan mode resuming outside plan mode in the VS Code extension or with '--continue'/'--resume' with a permission prompt tool
• Fixed the 'Notification' hook not firing while the sandbox 'Network request outside of sandbox' permission prompt is waiting
• Fixed Bash permission checks to always require approval for malformed commands with dangling '&&' or '||' operators
• Fixed '--strict-mcp-config' sessions prompting to approve servers they would never load, leaving background sessions waiting at startup
• Fixed telemetry and metrics requests to Anthropic carrying the API key for a third-party gateway; credential now only sent to its own host
• Fixed a visible API error on the first prompt after idle when 'apiKeyHelper' returns short-lived JWTs; expired tokens are now refreshed before sending
• Fixed memory growing with session length in fullscreen and Ctrl+O transcript views by optimizing message row rendering
• Fixed '/ultrareview' runs and cloud sessions launched simultaneously from one repository sometimes starting with another launch's uncommitted changes
• Fixed the task progress count for background cloud sessions occasionally missing a task
• Fixed Remote Control sessions keeping their placeholder name in claude.ai and the Claude app until the second prompt; auto-generated title now appears after the first prompt
• Fixed MCP tools marked 'requiresUserInteraction' still offering 'Yes, and don't ask again' in their permission prompt
• Fixed the self-hosted runner ending live sessions or exiting when a work-poll response is malformed; now retries the poll
• Fixed prompts beginning with '/--' (e.g. Lean doc comments) being rejected as an unknown slash command instead of being sent to Claude
