Download Claude Code 2.1.91

- Added MCP tool result persistence override via _meta["anthropic/maxResultSizeChars"] annotation (up to 500K), allowing larger results like DB schemas to pass through without truncation
- Added disableSkillShellExecution setting to disable inline shell execution in skills, custom slash commands, and plugin commands
- Added support for multi-line prompts in claude-cli://open?q= deep links (encoded newlines %0A no longer rejected)
- Plugins can now ship executables under bin/ and invoke them as bare commands from the Bash tool
- Fixed transcript chain breaks on --resume that could lose conversation history when async transcript writes fail silently
- Fixed cmd+delete not deleting to start of line on iTerm2, kitty, WezTerm, Ghostty, and Windows Terminal
- Fixed plan mode in remote sessions losing track of the plan file after a container restart, which caused permission prompts on plan edits and an empty plan-approval modal
- Fixed JSON schema validation for permissions.defaultMode: "auto" in settings.json
- Fixed Windows version cleanup not protecting the active version's rollback copy
- /feedback now explains why it's unavailable instead of disappearing from the slash menu
- Improved /claude-api skill guidance for agent design patterns including tool surface decisions, context management, and caching strategy
- Improved performance: faster stripAnsi on Bun by routing through Bun.stripANSI
- Edit tool now uses shorter old_string anchors, reducing output tokens
