A new Claude Code update brings Language Server Protocol (LSP) support, background agents for long-running tasks, and an "Ultrathink" mode aimed at deeper reasoning. LSP support should let the assistant tap existing language tooling for symbols and diagnostics, while background agents can work across the repo over time. Ultrathink appears to trade latency for higher-quality planning on complex changes.
LSP integration can improve code edits by leveraging your existing language diagnostics and symbol graph.
Background agents enable unattended repo-wide work like analysis, refactors, or documentation sweeps.
-
terminal
Evaluate LSP-aware edits on a polyglot service (e.g., Python + TypeScript) and compare diagnostics-driven fixes versus baseline AI suggestions.
-
terminal
Trial a background agent on a controlled branch to run a repo-wide task (e.g., deprecation cleanup) and measure accuracy, runtime, and PR quality.
