name: terminal-component description: Change Terminal UI or behavior. Use when working with the Terminal component, command registry, terminal commands, terminal hooks, or terminal cookie state.

Terminal component

Guidance for the Terminal feature (interactive CLI-style UI on the home page).

Entry and loading

• Wrapper: components/mate/terminal/terminal.wrapper.tsx — loads components/mate/terminal/terminal.tsx via next/dynamic with TerminalSkeleton, ssr: false.
• Skeleton: components/mate/terminal/terminal.skeleton.tsx. Use as the dynamic loading fallback.

Command system

• Registry: components/mate/terminal/command-registry.ts — singleton registry; registerGroup(name, commands), getAllCommands(), getCommandMap() (name + aliases, lowercased).
• Registration: components/mate/terminal/commands/index.ts — registers groups: System, Personal, Social, Navigation (links, site), Fun (ait). Add new commands here or in the appropriate group file.
• Command groups: components/mate/terminal/commands/system.ts, components/mate/terminal/commands/personal.ts, components/mate/terminal/commands/social.ts, components/mate/terminal/commands/navigation.ts, components/mate/terminal/commands/ait.ts.
• Types: components/mate/terminal/types/commands.ts — Command, CommandGroup, CommandRegistry. Commands have name, aliases?, description, run (and optionally UI).

Hooks

• components/mate/terminal/hooks/use-terminal-state.ts — terminal state (messages, history, etc.).
• components/mate/terminal/hooks/use-terminal-input.ts — input handling.
• components/mate/terminal/hooks/use-command-runner.tsx — runs commands from registry.
• components/mate/terminal/hooks/use-command-executor.ts — execution flow.

UI pieces

• Line: components/mate/terminal/line.tsx — renders a terminal line (command, output).
• Input: components/mate/terminal/terminal-input.tsx.
• Context: components/mate/terminal/command-context.tsx — provides command context to children.
• Constants: components/mate/terminal/constants.ts — default prompt, height, messages.
• Utils: components/mate/terminal/utils/formatting.ts, components/mate/terminal/utils/linkify.ts.

Cookie state

• lib/utils/cookies/terminal.cookie.ts — terminalCookie: get(), set(), remove(), hasVisitedRecently(). Schema: hasVisited, lastVisited. Used to remember if the user has visited the terminal (e.g. for onboarding or banners). Max age 72 hours.

Accessibility

• The terminal or carousel may use biome-ignore for a11y exceptions (e.g. focus management in custom interactive regions). Document any exception and keep keyboard navigation and screen reader behavior in mind; see CLAUDE.md for project a11y standards.

Adding a new command

1. Define the command in the appropriate group file (e.g. commands/personal.ts) with name, description, run, and optional aliases.
2. Register the group (or add the command to an existing group) in components/mate/terminal/commands/index.ts.
3. Ensure run returns output compatible with the line renderer (e.g. string or structured output the UI understands).
