Claude Code 2.1.153: Git LFS, MCP Fixes, Background Session Improvements

TL;DR

• Skip Git LFS downloads with new skipLfs option for faster clones
• Major background session fixes: terminal rendering, clipboard sync, session recovery
• MCP server stability improvements and subagent configuration fixes
• Model picker now saves your default selection across sessions

New

• Git LFS skip option — skipLfs flag for github/git plugin sources to skip LFS downloads during clone and update operations
• Terminal environment variables — Status line commands now receive COLUMNS and LINES so scripts can size output correctly
• Agent autocomplete — claude agents dispatch input now suggests native slash commands and bundled skills alongside project skills
• Model selection persistence — /model now saves your choice as default for new sessions; press s to switch for current session only
• PR column clarity — claude agents now displays PR #N for single PRs or N PRs for multiple
• Update diagnostics — claude doctor now shows results of your last update attempt; npm global installs display one-time notice when auto-update fails
• macOS background agents — Now appear as "Claude Code" in Privacy & Security and retain permission grants across upgrades

Fixed

• Stateful MCP servers without optional GET SSE stream were reconnect-looping on tools/list (regression from v2.1.147)
• Custom API gateways receiving user's Anthropic OAuth credential instead of gateway's own token
• Subagent MCP servers ignoring --strict-mcp-config, --bare, remote mode, and managed policies; now surfaces visible warnings for blocked servers
• --strict-mcp-config no longer strips inline mcpServers from explicit agent definitions
• Windows PowerShell installer falsely reporting success when installation failed
• claude update installing latest version instead of configured release channel version for npm
• Excessive memory usage (multiple GB) when resuming sessions by transcript file path on machines with many stored sessions
• claude agents and claude --bg running on stale daemon after binary-takeover support upgrade
• CLI hang when stdin closed without EOF in stream-json mode, leaving stale session marker
• Malformed file:// links in Claude's responses not clickable in terminal
• claude --help rendering unwrapped on terminals narrower than 92 columns
• MCP tool progress notifications not rendering in collapsed tool view
• Agent tool with subagent_type: 'claude' running in undocumented temporary worktree, silently discarding outputs to gitignored paths
• Background session clipboard sync (/copy and copy-on-select) failing silently inside tmux
• Background session terminal rendering: IME candidate window position on Windows, background-color bleed from 256-color terminals, cmd+k repainting in iTerm2/Terminal.app
• /btw keyboard shortcuts becoming unresponsive in background sessions during tasks
• Background sessions writing temp files to $CLAUDE_JOB_DIR triggering "sensitive file" permission prompts
• Recovering deleted background agent working directory showing truncated stack trace instead of clear error
• EnterWorktree not immediately available in background sessions
• /bg while Claude responds now continues response in background instead of dropping it
• /rename in background sessions not updating session banner immediately
• Remote Control leaving zombie session entries on Code tab after exiting claude agents
• Windows update rollback now restores original executable by copy with recovery instructions
• VSCode: Claude Code processes not shutting down cleanly on Windows, causing false "unclean exit" reports and orphaned MCP servers
• Combined separate "needs authentication" notifications for MCP servers and connectors into single message

Breaking Changes

• If you customized modelPicker:setAsDefault keybinding, rename it to modelPicker:thisSessionOnly in keybindings.json — the d action was replaced by s
