Parent Epic

Part of #11762 (Ink-based TUI Rewrite)

Objective

Port the existing slash command system to the Ink architecture.

Current Commands (from commands.ts)

Command Description
/help Show help
/clear Clear screen
/agent [name] Switch agent
/model [name] Switch model
/session [id] Switch session
/sessions List sessions
/new New session
/compact Toggle compact mode
/start Initialize context
/bug Report bug
/cost Show token costs
/config Edit config
/quit Exit

Architecture

// Command registry
interface Command {
  name: string
  description: string
  handler: (args: string[], context: CommandContext) => Promise<void>
}

interface CommandContext {
  dispatch: Dispatch<Action>
  session: SessionState
  setUIMode: (mode: UIMode) => void
}

const commands: Command[] = [
  {
    name: 'help',
    description: 'Show available commands',
    handler: async (args, ctx) => {
      ctx.dispatch({ type: 'SHOW_HELP' })
    }
  },
  {
    name: 'agent',
    description: 'Switch agent',
    handler: async (args, ctx) => {
      if (args[0]) {
        await switchAgent(args[0])
      } else {
        ctx.setUIMode('select')
        ctx.dispatch({ type: 'SHOW_AGENT_SELECT' })
      }
    }
  },
  // ...
]

// Command execution
function executeCommand(input: string, context: CommandContext) {
  const [cmd, ...args] = input.slice(1).split(' ')
  const command = commands.find(c => c.name === cmd)
  if (command) {
    return command.handler(args, context)
  }
  throw new Error(`Unknown command: ${cmd}`)
}

Tasks

  • Create src/cli/ink/commands/registry.ts - command definitions
  • Create src/cli/ink/commands/handlers/ - individual command handlers
  • Implement help command
  • Implement agent/model switching with SelectMenu
  • Implement session management commands
  • Implement utility commands (clear, compact, cost)
  • Implement /start command for context initialization
  • Wire up command execution in InputLine

Acceptance Criteria

  • All existing commands work
  • /help shows all commands
  • /agent and /model show selection menus
  • /sessions lists and allows selection
  • Unknown commands show error

Estimated Effort

1 day

Risk

Low - porting existing logic
