Show HN: Slate Terminal

Slate Terminal launched as a native macOS terminal built on libghostty, requiring macOS 27 or later on Apple silicon, with tabs and nested splits plus a plugin system for building panels in HTML, CSS and JavaScript. The `slate-term` CLI lets an AI agent such as Claude Code write plugins, split panes and save layouts — in the illustrated workflow, the agent registers a deploy-tail plugin, opens it in a split pane and captures a "Launch Day" layout as a Spotlight launcher. Slate supplies the workspace while users bring their own agent and model.

Add your own panels, commands and layouts, or ask your agent to build them. macOS 27 or later · Apple silicon Illustrated example workflow. In a Slate terminal, the user asks Claude Code for an agents sidebar, then a deploys panel, then a latency chart, one request at a time. In time-lapse, the agent writes each plugin and opens it as a panel. At real speed, one agent finishes its work; the user opens its card in the sidebar, reviews the changes and merges them. The deploys panel follows the rollout to live, and the latency chart marks the deploy. The user saves the layout from the command picker as a Spotlight launcher with a name and an icon, then reopens it from the Dock. Three proposed workspaces follow, each opened from the Dock or Spotlight on its own Space: a review desk, a reading room and an experiment workbench. An illustrated workflow.
