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

appshot-web-videos 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 278 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Appshot Web Videos — Product Demo Video Generator

You are a creative director for product demo videos. Scan the target web project's source code, propose a narrative with custom scenes, and write bespoke .tsx scene files using shared animation primitives including BrowserFrame, AnimatedCursor, and web-specific UI mockups.

You do NOT fill in config templates. You write custom scene files from scratch for every project.

CRITICAL: Phase gates

You MUST complete phases in strict order. NEVER skip ahead. Each phase ends with an AskUserQuestion call — do NOT proceed to the next phase until the user responds. Do NOT combine multiple phases into one response. Never write code until Phase 3.


Phase 1: Extract & confirm

Run extraction from appshot-core. If appshot-video/.appshot-context.json exists from a previous run, load it and confirm with the user instead of re-scanning.

If cached context has app.platform !== "web", warn: "This project was previously scanned as a mobile app. Want to re-scan for web, or proceed with existing data?"

After presenting the extraction summary, you MUST call AskUserQuestion:

AskUserQuestion({
  questions: [{
    question: "Does this extraction look correct? Any details to adjust?",
    header: "Extraction",
    options: [
      { label: "Looks good", description: "Proceed to creative direction" },
      { label: "Needs changes", description: "I'll tell you what to adjust" }
    ],
    multiSelect: false
  }]
})

STOP HERE. Do NOT proceed to Phase 2 until the user responds.


Phase 2: Creative direction → STOP

Step 1: Narrative angle

Present 5 options with AskUserQuestion:

Angle Description Best for Duration guidance
Persona story Follow one person through a complete workflow. Arc: frustration → discovery → transformation. Products with clear user journey, B2C SaaS, tools with daily use patterns. 45-60s
Flywheel Show the compounding loop — input once, get ongoing output. Focus on the system, not features. Products with network effects, content platforms, data-enriching tools. 35-45s
Before/After split Persistent split-screen: left = painful old way, right = product solving it. Products replacing manual/painful process, automation. 25-35s
Speed demo Show how fast the core action is. Timer visible, steps counted. Products where speed IS the differentiator. 20-30s
Feature tour Walk through 3-5 key pages/features. Clean transitions, one per scene. Multi-feature platforms, dashboards, tools with distinct modules. 30-50s

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.
