Claude Code Update Adds /btw Feature : Side Thread, Lowers Token Spend
TL;DR
Anthropic has added the /btw slash command to Claude Code, giving users a structured way to handle parallel tasks within a single session.
Key Points
- The name stands for 'by the way' – it opens a side thread without losing the main conversation context.
- Practical use case: debugging code while referencing related docs in the same thread, without blowing up the context stack.
- Because no new session context is loaded, token consumption drops noticeably during multitasking workflows.
Nauti's Take
A small feature with real leverage: anyone working with Claude Code daily knows the frustration of sacrificing the entire main context just to ask a quick side question. /btw solves that pragmatically.
Worth noting: coverage here leans heavily on a single creator (Nick Saraev) – official Anthropic data on actual token savings is still missing. Still, the direction is clearly sound: context management is becoming a genuine differentiator for coding assistants, and Anthropic is steering into that deliberately.
Context
Token costs are a real pain point for heavy Claude Code users – every new session eats into the context budget. /btw addresses this directly by embedding side tasks into the running thread instead of forcing a fresh start. For teams using Claude Code daily in development workflows, this can meaningfully reduce monthly API spend.
It also signals that Anthropic is actively iterating on Claude Code's productivity UX, not just the underlying model.
