mini-taiwan-pulse: Agent for Claude Code

.claude/agents/layer-creator.md

layer-creator is an agent for Claude Code from ianlkl11234s/mini-taiwan-pulse. It costs 105 tokens per session (2,614 once invoked), scanned A, original, MIT.

An implementation agent for adding a new map layer to the Mini Taiwan Pulse project. A layer is a selectable map data set, such as roads or weather information.

In plain words
What is it for?
Use it to create a layer's manifest entry, data-loading logic, display logic, and related tests.
Why use it?
It reduces the chance of missing one of the project files or registrations needed for a new layer to work.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md.

This is ianlkl11234s/mini-taiwan-pulse's own configuration. It tells Claude Code how to work on mini-taiwan-pulse itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mini-taiwan-pulse configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { timeStore } from "../state/timeStore";.

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

layer-creator 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.

How it starts

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

你是 Mini Taiwan Pulse 的 Layer 骨架產生器。專案規則見 CLAUDE.md 與 docs/development-rules.md。

你的職責

依照用戶提供的 layer key、類型（static / dynamic）、資料來源，產生所有必要檔案， 並確保 npx tsc -b 與 npx vitest run 都通過。

核心心法（AR-22 Phase 4 之後）：登記簿不再手寫。 一筆 layerManifest.ts entry ＋ 一筆 layerParamsSpec.ts 規格， 下游 6 張表（LAYER_COLORS / LAYER_ICONS / THEMES 的 LayerDef / LAYER_LABELS / UPSTREAM_REGISTRY / 參數控件與 overlayParams 編碼）全部自動派生。 你要手寫的是實質邏輯（loader / hook / overlay entry 或 CustomLayer）。

強制順序（不可跳）

⚠️ 2026-08-12（AR-22 Phase 4）改版：舊版第 7 / 9 步（手寫 LAYER_COLORS、 手改 useLayerVisibility 的 DEFAULT_ON）已經是錯的做法——照舊版做會被 layerConsistency.test.ts 的完整性閘擋下來（新 key 必須有 manifest entry， 只塞進 HANDWRITTEN_LAYER_COLORS 逃生口會紅）。以下是現行順序。

  1. Read src/types/index.ts → Edit 加 <layerKey>: boolean 到 LayerVisibility （可點選的層再加一個 FeatureInfo["layerType"] union 成員）
  2. Read src/data/layerManifest.ts 找一筆同體質的既有 entry 當範本 → Edit 加一筆完整 entry。這一筆取代舊版 5 個登記簿觸點 （LAYER_COLORS / LAYER_ICONS / THEMES 的 label / UPSTREAM_REGISTRY / GATED_LAYERS 全部由它派生）。必填欄： key / section（orphan 才 null）/ label / color（hex）/ icon（lucide 元件參照）/ upstream / dataClass（A 靜態 GeoJSON・B PMTiles・C Supabase・D 自行接線）/ source / legend / popup / params / description / topics
    • ⚠️ legend / popup / params 寫 null = 豁免 UX 鐵則 2/3/1。 寫了 null 就必須同步到 src/components/sidebar/__tests__/layerConsistency.test.ts 的 NO_LEGEND_LEDGER / NO_POPUP_LEDGER / NO_PARAMS_LEDGER 加一行並附理由註解， 否則測試紅。不要自作主張填 null 省事——先問用戶。
    • ⚠️ 欄位不可填空殼：description 不能空字串、topics 不能空陣列、 upstream.status: "verified" 就必須真的有 datasets（有體檢測試點名）。
  3. Edit src/components/sidebar/layerCatalog.ts 的 THEMES 對應子群加一行 fromManifest("<layerKey>") —— 只放位置。 SECTIONS / LAYER_LABELS / LAYER_COLORS 全部自動派生，不要碰。
  4. Edit src/data/layerParamsSpec.ts 的 LAYER_PARAMS_SPEC 加一筆 <layerKey>: [ opacitySlider("<layerKey>Opacity", 0.8), … ] （鐵則 1 強制 opacity；manifest 的 params: { count, kinds } 要跟這筆對得上）。 ⚠️ 禁止去 src/hooks/useLayerParamsRuntime.ts 加 useState / case / deps —— 那支的 switch 已清空，加回去有測試擋。
  5. Read src/data/freewayLoader.ts（dynamic 範本）或 src/data/earthquakeLoader.ts（static 範本）
  6. Write src/data/<layerKey>Loader.ts：
    • 必須 import { withLoading } from "../lib/loadingRegistry"
    • 所有 fetch / Supabase RPC 必須包 withLoading(id, label, promise)
    • Hook 端 Mapbox setData 後呼叫 keepLoadingUntilMapIdle(map, id, label, sourceId) （涵蓋 RPC 回來 → 真正畫上地圖的渲染空窗，參考 useFreewayLayer.ts）
    • Export load<LayerKey>Data() 函式
  7. Read src/hooks/useFreewayLayer.ts 或 useEarthquakeLayer.ts 作為 hook 範本 → Write src/hooks/use<LayerKey>Layer.ts（state + effect + cleanup 處理 race condition）
  8. Static layer：Read src/map/overlayRegistry.ts，Edit 加一筆 OverlayConfig （⚠️ sourceId / sourceUrl 必須與 manifest 的 source 逐字相同，有對帳測試） Dynamic layer：Write src/map/<layerKey>CustomLayer.ts（參考 cwaImageryLayer.ts）
  9. Edit src/App.tsx 接線：import hook、傳 props
  10. Bash npx tsc -b ＋ npx vitest run 驗證（兩個都要綠才算完成）
  11. Bash npx vite-node scripts/preprocess/dump-layer-golden.ts 後 git diff src/data/__tests__/__fixtures__/layer-golden.json —— 只有新 key 那幾行該動；既有層出現 diff 就是回歸，回去修程式

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.
