ClaudeDevs shipped a Claude Code weekly batch aimed at startup latency, token observability, and mobile remote control. The CLI no longer waits for the sandbox and MCP servers before accepting input; the Linux x64 download is about 4.5x smaller at roughly 75 MB, and native builds use 40–70 MB less memory per session. /cost now shows a prompt-cache line, /usage breaks down /loop runs and tokens so teams can see which loops burn quota, and /tasks lists each subagent's model and effort level. An Auto mode tab in /permissions exposes default allow/block rules and custom additions without hand-editing ~/.claude/settings.json. Remote Control reconnects after a server-side disconnect instead of exiting, surfaces permission prompts and new messages on phone after reconnect, and lets you watch a foreground subagent's tool calls live. Anthropic asked users to run `claude update`.
Key Takeaways
- ✓CLI startup no longer blocks on sandbox or MCP; Linux x64 is ~75 MB with 40–70 MB less RAM per session.
- ✓/cost, /usage, and /tasks now expose cache hits, loop token burn, and subagent model/effort.
- ✓Auto mode rules live in /permissions; Remote Control reconnects and streams subagent tool calls to phone.
