Pattern: The Terminal Emulator Became a Contested Layer in the AI Coding Stack
GitHub·low signal
Two AI-native terminals moved in the same week: Kaku shipped v0.18.0 "Detached" on 2026-08-08 (5,750 stars, Rust) with tab-and-pane detaching into new windows, following a v0.17.0 that added Responses API endpoints and native web search without separate keys; and VelaTerm open-sourced under MIT on 2026-08-09. Both bet that the shell wrapper — not the editor — is where agent context, credentials, and provider config should live. Kaku's v0.16.0 change requiring local authentication for shell control messages, so terminal output can't borrow configured credentials, is the security detail worth copying.
