weapp-tailwindcss-runtime

Guidance for using weapp-tailwindcss runtime packages in small-program projects. It covers combining Tailwind class names, choosing variant helpers, handling escaped classes, and keeping runtime classes aligned with build-time scanning.

In plain words
What is it for?
Use it when building dynamic class combinations, component variants, class overrides, custom runtime helpers, or RPX transformations with weapp-tailwindcss.
Why use it?
It prevents class conflicts, incorrect escaping, and missing styles caused by dynamic class names. It also clarifies which runtime package fits common component patterns.

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

weapp-tailwindcss-runtime 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.

What it actually says

weapp-tailwindcss runtime

使用项目提供的运行时封装保持 class 合并、转义和构建期精确候选一致。

工作流

  1. 识别 class 来源:静态模板、完整字面量条件、组件外部覆盖、第三方透传或真正的运行时输入。
  2. 读取 references/runtime-guide.md,按任务选择最小包和 API。
  3. 读取各包当前 manifest 与 exports,避免把 merge/slimmerge/lite、UI CSS 或插件入口当成主入口。
  4. 优先使用完整 class 字面量或枚举;不要拼接 bg-${color}-500 这类半截 token。
  5. 普通组件覆盖使用 @weapp-tailwindcss/merge;单槽 variants 使用 @weapp-tailwindcss/cva;多槽 recipes 使用 @weapp-tailwindcss/variants
  6. 自定义封装名时检查构建期可识别标识符;需要原样透传时使用 weappTwIgnore,不要扩大全局忽略。
  7. 自定义 runtime factory、escape/unescape 或 rpx transformer 时保持纯函数边界,并验证缓存淘汰前后的等价输出。

关键约束

  • 运行时包已经封装小程序 escape/unescape;不要先手动 escape 再交给 merge/cva/variants。
  • clsx 只负责组合,不解决 Tailwind 冲突;需要“调用方最后覆盖”时使用 merge。
  • 只有会改变冲突分类的自定义 Tailwind token 才同步 merge 配置,并补冲突用例。
  • weappTwIgnore 是精确局部保护,不是让未扫描动态 class 自动生成 CSS 的工具。
  • 构建期仍遵循 classNameSet 精确命中,运行时封装不能补生成缺失的候选。

输出要求

输出包选择理由、可复制实现、构建期配套配置、类型约束,以及冲突、转义和生产压缩验证用例。

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
