A presentation workflow for turning HyperFrames scenes into a live slideshow. It supports slides, step-by-step reveals, clickable navigation areas, and presenter notes rather than producing an MP4 video.

Use it to build or convert a deck for live presentation, with fragment reveals, branching links, hotspots, and speaker notes.

It separates live presentations from rendered videos and records slide structure and navigation directly in the composition.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00057	$0.01161
Opus 5.5	$0.00023	$0.00464
Sonnet 5.5	$0.00011	$0.00232
Haiku 4.5	$0.00006	$0.00116

Security

Grade A, and why

slideshow 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 2d ago.

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.

HyperFrames slideshow

A slideshow is a normal composition (the /hyperframes contract applies) plus one JSON island that says which scenes are slides and how they connect. The deliverable is a running deck, not an MP4.

What changes from a video project

Each slide is a top-level scene in the composition file: data-composition-id, data-start, data-duration, data-label, data-width, data-height. There is no master root composition wrapping them.
One island per composition, near the top of <body>, written in the HTML (never generated by script; present reads the file statically):

<script type="application/hyperframes-slideshow+json">
  {
    "slides": [
      { "sceneId": "hook", "notes": "Pause on the number." },
      {
        "sceneId": "problem",
        "fragments": [11.0, 15.0],
        "hotspots": [
          {
            "id": "h1",
            "label": "Where does $40B come from?",
            "target": "market-detail",
            "region": { "x": 55, "y": 60, "w": 40, "h": 20 }
          }
        ]
      }
    ],
    "slideSequences": [
      { "id": "market-detail", "label": "Market sizing", "slides": [{ "sceneId": "mkt-math" }] }
    ]
  }
</script>

sceneId equals a scene's data-composition-id (or give startTime/endTime). notes are presenter-only. ttsScript, ttsAudioUrl and ttsDurationMs are reserved and not wired yet.
Fragments are absolute timeline times (the same clock as data-start, not offsets inside the slide) within the slide's [start, end]. Navigation seeks, it never plays: each hold state must look right when the timeline is seeked straight to that time. A slide without fragments enters at a rest frame inside it.
Branch slides are ordinary scenes listed only in slideSequences, never in the main slides array. A hotspot's target is a sequence id; region is a percentage box (omit it for a full-slide button). Back returns to the slide that held the hotspot.
Text the audience must read is at least 40 px at 1920×1080. Before hand-building any named visual, search npx hyperframes catalog --query "<the visual, in English>" --json: it ranks the whole registry with nothing installed.

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.

slideshow is a skill published in the GitHub repository cafe3310/public-agent-skills (256 stars, last pushed yesterday), licensed Apache-2.0. It adds 57 tokens to every session and 1,161 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-11-05.
