What is cinematic-scroll-landing CLAUDE.md?

A project guide for a cinematic scrolling landing page, where the page content moves through a planned visual sequence as the user scrolls. It also documents the related development skill and its demo project.

Use it when developing or checking the cinematic-scroll-landing project, including local development, image audits, automated tests, screenshot sweeps, browser-console checks, and deployment.

It collects the commands and rules needed to update the active skill, run checks, test the demo, capture screenshots, and deploy it.

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	$0.00523	$0.00523
Opus 5	$0.00262	$0.00262
Sonnet 5	$0.00105	$0.00105
Haiku 4.5	$0.00052	$0.00052

Security

Grade A, and why

cinematic-scroll-landing CLAUDE.md 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 9d 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.

What it actually says

cinematic-scroll-landing — project guide

Dual-purpose repo: the cinematic-scroll-landing skill (dev master at the repo root: SKILL.md, references/, scripts/) and its living proof, the Codex Academy demo (demo/ — a full-page book-scroll landing page for a fictional Moodle LMS trial).

The install rule (the one thing not to forget)

The ACTIVE skill copy is ~/.claude/skills/cinematic-scroll-landing/. Editing repo files does nothing until re-copied:

cp SKILL.md ~/.claude/skills/cinematic-scroll-landing/
cp references/*.md ~/.claude/skills/cinematic-scroll-landing/references/
cp scripts/*.py ~/.claude/skills/cinematic-scroll-landing/scripts/

Demo commands

In demo/: npm run dev / build / preview; npx vitest run (11 tests: timeline math + content wiring).
From repo root: python scripts/audit_images.py demo (image wiring audit).
In demo/: node shoot.mjs <url> <outdir> (screenshot sweep at exact timeline units via the window.__lenis hook) and node console-check.mjs <url> (error sweep across the full scroll).

Deploy

npx vercel deploy --prod --yes from demo/ (CLI already authed; project codex-academy, team kash12). Live: https://codex-academy-five.vercel.app — plain codex-academy.vercel.app is SOMEONE ELSE'S site. .vercel/ stays gitignored.

Imagery

Generated via the banana skill's direct-API fallback script with the key at ~/.banana/api_key.txt; locked template + generation-ops rules in references/imagery-universe.md. Generator originals land in ~/Documents/nanobanana_generated/; only optimized WebP/JPEG (see ship-size discipline) enter demo/public/.

Policies (this demo deploys publicly)

CTA intentionally inert; no forms or data collection; all institutions, people, and stats fictional; "Powered by Moodle™" is nominative credit only.

History

Spec, plan, and retrospective live in docs/superpowers/. The original kimi-3-swarm skill is preserved as the baseline commit.

Changes

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.
