Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00134 | $0.01834 |
| Opus 5 | $0.00067 | $0.00917 |
| Sonnet 5 | $0.00027 | $0.00367 |
| Haiku 4.5 | $0.00013 | $0.00183 |
Grade A, and why
skyline-scroll-api 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 4d 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.

Skyline 滚动控制 API
适用场景
- 程序化触发 scroll-view 下拉刷新或关闭刷新
- 程序化触发/关闭下拉二级（"二楼"页面）
- 通过 ScrollViewContext 控制滚动位置和行为
- 控制 DraggableSheet 半屏面板滚动到指定位置
- 在 worklet 函数中（UI 线程）直接控制 scroll-view 滚动
核心概念
三大 API 族群
| API 族群 | 获取方式 | 线程 | 最低基础库 |
|---|---|---|---|
| ScrollViewContext | NodesRef.node() + enhanced 属性 |
逻辑线程 | 2.14.4 |
| DraggableSheetContext | NodesRef.node() |
逻辑线程 | 3.2.0 |
| worklet.scrollViewContext | NodesRef.ref() + SharedValue |
UI 线程 | 3.3.0 |
获取实例
// ScrollViewContext（需开启 enhanced）
wx.createSelectorQuery().select('#scrollview').node()
.exec(res => { const ctx = res[0].node })
// DraggableSheetContext
wx.createSelectorQuery().select('.sheet').node()
.exec(res => { const ctx = res[0].node })
// worklet.scrollViewContext（通过 ref）
this.scrollRef = wx.worklet.shared()
this.createSelectorQuery().select('.scrollable')
.ref(res => { this.scrollRef.value = res.ref }).exec()
文档索引
根据需求快速定位（路径相对于 references/）：
| 我想要... | 查阅文档 |
|---|---|
| 查看 ScrollViewContext 全部方法和属性 | api/scroll-view-context.md |
| 了解 DraggableSheetContext.scrollTo 参数 | api/draggable-sheet-context.md |
| 在 worklet 中控制滚动 | api/worklet-scroll-context.md |
| 查看完整代码模式（刷新、二级、Sheet 控制） | patterns.md |
强制规则
MUST（必须遵守）
-
scroll-view 必须开启
enhanced属性才能获取 ScrollViewContext：<!-- ❌ 错误：未开启 enhanced，node() 返回的不是 ScrollViewContext --> <scroll-view type="list" scroll-y> <!-- ✅ 正确 --> <scroll-view type="list" scroll-y enhanced> -
DraggableSheetContext.scrollTo 中 size 和 pixels 同时传入时，仅 size 生效：
// ❌ 错误：同时传入 size 和 pixels，pixels 被忽略 sheetContext.scrollTo({ size: 0.7, pixels: 200 }) // ✅ 正确：二选一 sheetContext.scrollTo({ size: 0.7 }) // 相对位置 sheetContext.scrollTo({ pixels: 200 }) // 绝对位置 -
worklet.scrollViewContext 必须通过
NodesRef.ref获取引用并存入 SharedValue：// ❌ 错误：使用 node() 而非 ref() this.createSelectorQuery().select('.scroll').node() .exec(res => { /* 这是 ScrollViewContext，不是 worklet 引用 */ }) // ✅ 正确：使用 ref() + shared() this.scrollRef = wx.worklet.shared() this.createSelectorQuery().select('.scroll') .ref(res => { this.scrollRef.value = res.ref }).exec()
What ships with it
4 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.
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.

skyline-scroll-api is a skill published in the GitHub repository wechat-miniprogram/skyline-skills (52 stars, last pushed 3mo ago), licensed MIT. It adds 134 tokens to every session and 1,834 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
