當需要更新 immich-geodata-zh-tw 原始邊界資料、下載最新 TW/JP/KR/TH/ID 圖資、驗證 Shapefile/GeoJSON schema、執行 Rust extract/release pipeline，或驗證 release artifacts 時使用。

當需要更新 immich-geodata-zh-tw 原始邊界資料、下載最新 TW/JP/KR/TH 圖資、驗證 Shapefile/GeoJSON schema、執行 Rust extract/release pipeline，或驗證 release artifacts 時使用。

當使用者明確提出要為 immich-geodata-zh-tw 新增某個國家的 handler 時使用（例如「新增越南 handler」「加入菲律賓支援」「為某國寫 extract handler」），包含其前期規劃與研究。涵蓋來源選擇、schema 研究、座標與投影策略實驗、特殊行政結構盤點，以及 Wikidata translator 的搜尋語言研究、國家 QID 查證、P131 驗證設計與翻譯品質驗收。僅更新既有國家圖資或跑 release 時不適用（改用 immich-geodata-source-release）。

Use when designing a new system/user prompt for an LLM task (refinement, classification, extraction, formatting, single-turn agent). Builds prompts using the v4 framework — persona+rationale → XML structure → outcome-first task body → injection defenses → output contract. Iterates against real provider APIs when an API key is available; falls back to theory-only design if not. Always validates against attack-fixture suite before finalizing.

Use when an existing prompt is too long, costs too much per call, has poor cache hit-rate, or models stopped adhering to its rules (often after a model version bump). Compresses tokens AND hardens adherence in one pass — these usually go together. Always produces a before/after token comparison table. Iterates against real provider APIs when an API key is available; falls back to theory-only review if not.
