Claude Code and Codex CLI updates: compression, MCP tasks, mid-reply steering
Anthropic says Claude Code now gzip-compresses the conversation sent with every turn, so it reaches the model faster; the CLI also supports the MCP "Tasks" and "Elicitations" features. Codex CLI 0.163 lets users step in while the agent is still replying.
Who is affected and how
- senior developer
- After the updates, try mid-reply intervention so an agent that is editing the wrong file can be stopped in time.
- tech lead
- With MCP support expanding, the internal tool integrations of agents should be re-evaluated.
