What is cyxj-remotion-starter CLAUDE.md?

Repository instructions for a Remotion starter project, where React code is used to create videos frame by frame. The repository is a workflow guide rather than a complete video-rendering project.

Use it to start or update Remotion video projects, prepare scenes and props, follow the project’s checks, and render videos from the correct project directory.

It explains where new video projects belong, which files contain the real rules and assets, and which animation and review practices the project expects.

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	$0.01319	$0.01319
Opus 5	$0.00660	$0.00660
Sonnet 5	$0.00264	$0.00264
Haiku 4.5	$0.00132	$0.00132

Security

Grade A, and why

cyxj-remotion-starter 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 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.

CLAUDE.md

本文件给 Claude Code 用,是这个 Remotion 工作台脚手架的根路由。

这是一个「用 Claude Code 指挥 Remotion 出口播视频」的方法论骨架:三层架构 + hooks 守规矩 + skills 编排流程。它本身不是单个 Remotion 工程——仓库根没有 package.json,也不是渲染入口。实际出片在 template/(或你从它复制出的工程)里。

这份文件只回答四件事:站在仓库根时——该进哪里、不能做什么、规则去哪读、这套骨架怎么用。具体规则不写在这,在下面索引指向的真源里。

硬规则

新片从 template/ 起手:复制 template/ 到一个新目录 → npm install → 改 props.json → 渲。别把 .tsx / package.json / 素材散落到仓库根。
续作/迭代进已有工程目录里改,不另开目录。
仓库根禁跑 npm / npx remotion——没 package.json,命令一律先 cd 进 template/ 或你复制出的工程。
进任一出片工程前先读它自己的 CLAUDE.md / README.md——视觉禁区、流程禁区、组件约定在那,本文件不重复。
改 .tsx / props.json / 镜头前必走官方核查——三查提醒由 official-check-reminder hook 每轮注入,写不出核查内容 = 没查 = 不许改。纯聊天/问答轮不强制。
用 React + Remotion 帧驱动体系(interpolate/spring/Sequence/<Audio> 为主)——所有动效必须 useCurrentFrame() 驱动;不用 GSAP / CSS 动画(红线见 docs/HARD_RULES.md)。
造画面默认原生先行;复用是判断后的主动选择,不是开工反射。 用户说要「新镜头 / 新效果」时,默认就是真造——不许先翻库、拿「有个差不多的」把人劝退。完整 5 步判断在 overlay skill cyxj-remotion-overlay。

三层真源索引(规则/资产都在这些里,本文件不复制)

L0 官方层 —— 官方写法 / API / CLI 一律走这,别凭记忆: skill remotion-best-practices(npx skills add remotion-dev/skills)、MCP remotion-documentation(npx @remotion/mcp@latest)
L1 共享层(kit) —— 引擎级组件、5 个基础镜头、设计 token、schema、硬规则: kit/CLAUDE.md(它自带"要找什么 / 在哪"的索引)
L2 出片层 —— 怎么开新片、怎么出片: 起手模板 template/CLAUDE.md + 每个工程自己的 CLAUDE.md / README.md

目录路由

在哪	是什么
`kit/`	L1 共享真源:引擎级组件 / 基础镜头 / 设计 token(占位)/ schema
`template/`	起手模板(复制它开新片)
`docs/HARD_RULES.md`	硬规则唯一真源(框架红线)
`.claude/hooks/`	7 个守规矩钩子(硬规则拦截 / 渲染前确认 / 收工 typecheck+进化闸)
`.claude/agents/`	`remotion-rule-reviewer`(渲染前语义审)
`.claude/skills/`	3 个流程 skill(produce 编排 / overlay 画面 / evolve 沉淀)

这套骨架怎么用(hooks + skills)

hooks(.claude/settings.json 已接好,7 个):写 .tsx 前拦机械红线(hard-rules-guard);每轮把官方核查顶到眼前(official-check-reminder);跑渲染命令前弹确认(render-guard);收工前在改过的工程里跑 tsc(typecheck-on-stop)、并在动了代码没动文档时提醒沉淀(evolve-on-stop + 两个 record-* 记账)。
skills(.claude/skills/):cyxj-remotion-produce 管一条片的 8 阶段顺序;cyxj-remotion-overlay 管一段画面怎么做(原生先行 vs 复用);cyxj-remotion-evolve 管把学到的回写规则。

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.
