Implementation Plan: Agent Visuals & Responsive Layout

1. In-Chat Agent Visuals

Goal: Make agent persona switches (e.g., [AGENT: Security]) visually distinct in the chat history.

• Modify flattenMessagesToBlocks (bin/opencode-ink.mjs):
  • Regex match \[AGENT:\s*([^\]]+)\].
  • Create a new block type { type: 'agent_tag', name: 'Security' }.
• Add Test Case (tests/tui-components.test.mjs):
  • Verify flattenMessagesToBlocks correctly splits [AGENT: Name] strings into blocks.
  • Run node --experimental-vm-modules node_modules/jest/bin/jest.js tests/ to verify.
• Modify ViewportMessage (bin/opencode-ink.mjs):
  • Handle type === 'agent_tag'.
  • Render:

    h(Box, { borderStyle: 'round', borderColor: 'magenta', paddingX: 1, marginTop: 1 },
        h(Text, { color: 'magenta', bold: true }, '🤖 Security Agent')
    )
    

2. Hardened Responsive Layout

Goal: Prevent text wrapping/overflow when resizing the terminal.

• Audit markdown-ink-esm.mjs: Ensure it strictly respects the width prop.
• Audit ViewportMessage:
  • Ensure width prop passed to <Markdown> accounts for padding/gutters (e.g., width={width - 4}).
  • Check CodeCard width constraints.
• Verify App Layout:
  • calculateViewport should already be dynamic.
  • Ensure useTerminalSize is updating correctly.

Verification

• Run chat with "Using Security Agent...".
• Verify visible badge.
• Resize window narrower -> Text should wrap, not cut off.
