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 | $0.00129 | $0.02227 |
| Opus 5.5 | $0.00052 | $0.00891 |
| Sonnet 5.5 | $0.00026 | $0.00445 |
| Haiku 4.5 | $0.00013 | $0.00223 |
Grade A, and why
landing-page scanned grade A with 1 finding 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 1mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
landing-page
You maintain aidemo's public landing page. It is the project's pitch to humans AND its primary machine-readable source for LLM search (GEO). Every edit must serve both audiences.
Where things live
docs/index.html— the entire site: one self-contained file (inline CSS/JS).docs/llms.txt— curated map for LLM crawlers; MUST stay in sync with any positioning/feature claims changed on the page.docs/robots.txt— AI-crawler allowlist.docs/sitemap.xml— single URL.docs/hero-demo.mp4(1280×800 h264, copy of the release asset) +docs/hero-poster.jpg(poster frame, also the og:image).docs/icons/*.webp— card icons (176px, shown at 44px) + real customer logo marks;docs/favicon.png(64px, from the clapper icon). See "Icon system" below before adding one.docs/.nojekyll— keep; Pages servesdocs/verbatim frommain.docs/internal/is gitignored and private — never link to it from the page, and readdocs/internal/INDEXING_PLAN.mdfor strategy/decisions (domain-swap checklist lives there).
Deploy = push to main
Commit straight to main and push (no PRs in this repo). GitHub Pages
rebuilds in ~30–60 s. Always verify after pushing:
until curl -sL https://aidemo.top/ | grep -q "<distinctive new string>"; do sleep 6; done
(-L matters: tandryukha.github.io/aidemo now 301s to aidemo.top, so a bare
curl -s there greps a redirect stub and never matches.)
Run that check with Bash run_in_background: true, never a bare foreground sleep.
Hard rules (learned, do not relearn)
- Only claim what ships. No named future integrations or roadmap promises
on the page. (History: ElevenLabs was removed while planned, then claimed
once it shipped; the old "Codex/Gemini planned" exception is obsolete —
since v0.6.0 they work today via the built-in MCP server, as do the
ElevenLabs provider and the in-process local voice, and the page claims all
of them as shipped.) Describe extensibility via what's true in code
("swappable
VoiceProviderinterface"). - Positioning (approved): built for coding agents to autonomously record
product demos — landing-page hero videos, GitHub README walkthroughs,
what-shipped videos for customer release notes. Open-source alternative to
Screen Studio / Clueso / Demosmith. Keep this framing consistent across
hero sub, meta description, og:description, JSON-LD, and llms.txt.
Audience = developers (owner directive): write dev-to-dev — terminal-first
examples with real, runnable commands and real paths, no marketing fluff.
When showing an assistant/integration, show the actual command a developer
would type (if a genuinely unshipped integration ever needs showing, a
muted
# plannedcomment is the approved mechanism — currently none are). - Video, never GIF, for the hero. GIFs are 256-color mush (the old
560×350 GIF looked terrible upscaled). Use
<video autoplay muted loop playsinline preload="metadata" poster=...>with a same-origin MP4. Setwidth/heightattrs to the file's REAL dimensions (check withffprobe -v error -select_streams v:0 -show_entries stream=width,height -of csv=p=0 <file>) and keep CSSwidth:100%; height:auto; aspect-ratio: W / H— a mismatched height attribute stretches the frame. - Self-contained page. No CDN scripts, external fonts, or third-party
requests. Inline everything. Both color schemes must work
(
prefers-color-scheme+ the CSS variables at the top of the file). - FAQ and JSON-LD move together. Every visible FAQ
<details>has a matching entry in theFAQPageJSON-LD block, same wording. Question-shaped headings ("Can Claude Code record a demo video?") — LLM search lifts them verbatim. New claims also go intollms.txt. - Respect the motion system. Load stagger =
fade+d1..d5classes; scroll fade-in/out =revealclass picked up by the IntersectionObserver at the bottom of the file; everything is disabled underprefers-reduced-motion. New sections:class="reveal"on theh2and on each card/step/details. Don't add per-elementtransition-delaythat would lag hover states (.reveal.inresets it to 0s for this reason).
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.

landing-page is a skill published in the GitHub repository tandryukha/aidemo (20 stars, last pushed 7d ago), licensed MIT. It adds 129 tokens to every session and 2,227 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
