Claude Code v2.1.153 Ships Skip LFS, MCP Fixes, and Agent Autocomplete
Claude Code v2.1.153 dropped with a hefty changelog: Git LFS control, critical MCP server fixes, and improved agent UX. If you use github or git plugin marketplace sources, you can now pass skipLfs: true to avoid downloading LFS objects during clone and update — handy for repos with large binary assets.
Key Changes
- Git LFS: New
skipLfsoption ingithub/gitmarketplace source definitions to skip LFS downloads. - Auto-update notice: npm global installs that can't auto-update show a one-time notice;
/doctorlists the fixes. - Status line env vars: Status line commands now receive
COLUMNSandLINESfor proper terminal-aware output sizing. - Agent autocomplete: The dispatch input now suggests native slash commands and bundled skills, not just project skills.
- PR column: Shows
PR #Nfor single PR,N PRsfor multiple. claude doctornow shows the result of your last update attempt.- MCP server fixes: Fixed stateful MCP servers without optional GET SSE stream from reconnect-looping on
tools/list(regression from v2.1.147). Subagent MCP servers now respect--strict-mcp-config,--bare, remote mode, enterprise MCP config, and managed-settings allow/deny policies. The flag no longer strips inlinemcpServersfrom explicitly passed agent definitions, and blocked subagent servers now surface a visible warning. - Credentials fix: Fixed custom API gateway receiving Anthropic OAuth credential instead of the gateway's own token.
- Memory fix: Resolved excessive memory usage (multiple GB) when resuming a session by transcript file path on machines with many stored sessions.
- Daemon fix:
claude agentsandclaude --bgno longer run on a stale daemon started before binary-takeover support. - Hang fix: CLI no longer hangs when stdin is closed without EOF in stream-json mode, which left stale session markers.
- /bg behavior: Now continues the response in background session instead of dropping it.
- Windows: Update rollback restores original executable if update fails; PowerShell installer no longer falsely reports success on failure.
- /model: Saves your selection as default for new sessions (press
sto switch for current session only).
Who It's For
Anyone running Claude Code — especially if you use MCP servers, work in large repos with Git LFS, or run background agents.

Researchers released Talkie, a 13B LLM trained only on text published before 1931 (no internet, no WWII data). Claude Sonnet 4.6 was used as the judge in its online DPO reinforcement learning pipeline, and Claude Opus 4.4 generated synthetic multi-turn conversations for fine-tuning. The model can write Python code from a few in-context examples despite zero modern code in training.
