# v0.19.1 Release Notes

> v0.19.0 -> v0.19.1

## Summary

Refactor skill activation into a lazy-loaded `select_skill` tool, migrate sandbox and utility primitives to `go-utils`, and upgrade persistence/search internals with semantic session-history retrieval.
<details>
<summary>翻譯</summary>
將 skill 啟用流程重構為延遲載入的 `select_skill` 工具，將 sandbox 與共用工具基礎遷移至 `go-utils`，並升級持久化與搜尋內部機制，加入語意化 session 歷史檢索。
</details>

## Changes

### UPDATE
- Update session-history persistence to write vector-aware entries and extend `search_history` with merged keyword and semantic retrieval windows.
- Update runtime skill handling to detect `/skill-name` prefixes as hints, pass scanner context through executors, and synthesize skill activation into tool history.
- Update REST, Discord, and CLI execution paths to use the new skill-matching flow and refreshed system-prompt skill list.
- Update cache consumers for ToriiDB v0.5.1 entry accessors and refresh architecture/version documentation accordingly.

<details>
<summary>翻譯</summary>

- 更新 session 歷史持久化為可寫入向量的紀錄格式，並將 `search_history` 擴充為關鍵字與語意檢索視窗合併輸出。
- 更新執行期 skill 流程，將 `/skill-name` 前綴視為提示，於 executor 中傳遞 scanner context，並把 skill 啟用合成進 tool 歷史。
- 更新 REST、Discord 與 CLI 執行路徑，以採用新的 skill 比對流程與刷新後的 system prompt skill 清單。
- 更新 ToriiDB v0.5.1 快取讀取介面，並同步刷新架構與版本文件。

</details>

### ADD
- Add the always-loaded `select_skill` tool, dynamic `## Skills` prompt block generation, and lazy-load architecture documentation.
- Add `MatchSkillCall` slash-prefix detection and session-history helper functions for direct user-input persistence.

<details>
<summary>翻譯</summary>

- 新增永遠載入的 `select_skill` 工具、動態 `## Skills` prompt 區塊生成，以及 lazy-load 架構文件。
- 新增 `MatchSkillCall` slash 前綴偵測，以及直接持久化使用者輸入的 session history 輔助函式。

</details>

### REMOVE
- Remove the legacy LLM-based skill selector prompt, selection event type, and bundled internal sandbox implementation.
- Remove obsolete system-prompt sections that embedded full skill bodies directly.

<details>
<summary>翻譯</summary>

- 移除舊版以 LLM 驅動的 skill selector prompt、對應 selection event type，以及專案內建的 sandbox 實作。
- 移除過去直接把完整 skill 內容嵌入 system prompt 的舊區段。

</details>

### REFACTOR
- Refactor sandbox wrapping, UUID generation, keychain/http helpers, and script execution plumbing to depend on `go-utils` packages.
- Refactor executor construction and system-prompt rendering to be scanner-aware and skill-tool centric.

<details>
<summary>翻譯</summary>

- 重構 sandbox 包裝、UUID 生成、keychain/http 輔助與 script 執行管線，改為依賴 `go-utils` 套件。
- 重構 executor 建構與 system prompt 產生流程，使其具備 scanner 感知並以 skill tool 為核心。
