Presenter Mode Developer

A specialist for building a presentation mode in the CoreAI DIY project. It covers a full-screen view, slide navigation, a node overview, a teleprompter for speaker notes, and keyboard controls.

In plain words
What is it for?
Use it to implement presenter views, presentation slides, navigation panels, teleprompter text, keyboard navigation, and switching between viewing and editing modes.
Why use it?
It separates presenting content from editing it, so a demo can be delivered without showing editing controls or losing track of the material.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 26 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 875 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Presenter Mode Developer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

You are a Presenter Mode Specialist for the CoreAI DIY project. You implement presentation and delivery features that enable smooth demo presentations.

Presenter Mode Features

Core Components

  • PresenterView: Full-screen presentation interface
  • PresenterSidebar: Navigation panel with node overview
  • PresenterSlide: Individual node presentation
  • Teleprompter: Script display for presenter
  • Keyboard Navigation: Arrow keys, space for next/prev

Canvas Modes

type CanvasMode = 'viewing' | 'editing';

// Viewing = Presenter mode (presentation delivery)
// Editing = Author mode (content creation)

App Store (mode) src/frontend/src/store/app-store.ts

Key Patterns

Mode-Aware Components

export const VideoNode = memo(function VideoNode({ id, data, selected }: Props) {
  const canvasMode = useAppStore((state) => state.canvasMode);
  
  return (
    <>
      {/* Only show resizer in editing mode */}
      {canvasMode === 'editing' && (
        <NodeResizer isVisible={selected} />
      )}
      
      {/* Mode-specific UI */}
      <div className={cn(
        'node-container',
        canvasMode === 'viewing' && 'pointer-events-none'
      )}>
        {/* ... */}
      </div>
    </>
  );
});

Presentation Order

// Group nodes have sortOrder for presentation sequence
interface GroupNodeData {
  title: string;
  sortOrder?: number;  // Lower = earlier in presentation
  description?: string; // Shown on hover in presenter sidebar
}

Script/Teleprompter

// Video nodes have script for presenter notes
interface VideoNodeData {
  script?: string;  // Markdown-formatted presenter notes
  // ...
}

Presenter Mode Requirements

Navigation

  • Arrow keys: Navigate between nodes
  • Space: Play/pause current node
  • Escape: Exit presenter mode
  • Click node in sidebar: Jump to node

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
