+# Triage Findings
+
+When the task is to triage review findings, follow this workflow:
+
+1. Merge all findings into one list.
+2. Remove duplicates.
+3. Sort by severity: `critical` -> `warning` -> `info`.
+4. Renumber from 1 after sorting.
+5. Fix real issues with the smallest safe change.
+6. Add false positives to `.gitea/ai-review/exclusions.json`, preserving the original wording, language, and semantics as much as possible.
+7. Add or update tests when behavior changes.
+8. Re-check the issue after each fix.
+
+Use the repo-local `triage-findings` skill for the same workflow when running in Codex.

+   - info
+3. Renumber from 1.
+4. Fix real issues.
+5. Put false positives into `.gitea/ai-review/exclusions.json` as a top-level JSON array, preserving the original wording, language, and semantics as much as possible. Do not wrap the array in `exclusions` or `excluded_findings`.
+6. Add tests when behavior changes.
+
+## Output Rules
+
+- Keep the final list short.
+- Keep numbering contiguous.
+- Preserve file path, location, and fix.
+- When writing exclusions, always output a top-level JSON array.
+- When writing exclusions, prefer the original issue text over paraphrased rewrites.

+
+# Triage Findings
+
+## When To Use
+
+Use this skill when you receive multiple review findings, screenshots, comments, or issue lists that need to become one final triaged list.
+It is also used when some findings are false positives and should be moved into the exclusions list.
+
+## Workflow
+
+1. Collect all findings into one list.
+2. Merge duplicates into a single finding when they describe the same issue.
+3. Sort the final list by severity:
+   - critical
+   - warning
+   - info
+4. Renumber the sorted list from 1 upward.
+5. Rewrite each finding concisely so the final list reads cleanly and consistently.
+6. If a finding is a false positive, do not keep it in the final list.
+7. Add false positives to the exclusions list as a top-level JSON array in `.gitea/ai-review/exclusions.json`, and preserve the original finding wording as much as possible, including language and semantics. Do not wrap the array in `exclusions` or `excluded_findings`.
+
+## Resolution Flow
+
+After the list is merged and ordered, resolve the remaining findings one by one.
+
+1. Start from the highest severity item.
+2. Identify the root cause in the relevant file or context.
+3. Apply the smallest safe change that fixes the issue.
+4. Add or update tests when behavior changes.
+5. Re-check the issue after the change.
+6. If the item is confirmed false positive, move it to exclusions instead of changing code.
+7. Continue until the list is either fixed or explicitly excluded.
+
+## Output Rules
+
+- Keep the final findings list in severity order, then by any stable secondary order needed to make it readable.
+- Keep numbering contiguous after filtering and merging.
+- Preserve useful details like file path, location, and suggested fix.
+- Keep exclusions entries minimal and consistent with the project schema.
+- When writing exclusions, always output a top-level JSON array.
+- When writing exclusions, prefer the original issue text and language; only paraphrase if needed to fit the schema.
+- If the source already provides a severity or title, keep it unless it conflicts with the final ordering.

 1. 服務名稱、模型名稱、角色資訊(個性、符合個性的英文名稱、工作內容)，Comment 到 Push Request
 2. 每個角色個別分析 Git Diff 的內容產生新問題表格(問題等級、角色名稱、問題位置或行數、修改建議)
-3. 讀取所有未解決的舊問題(問題檔案 `.gitea/ai-review/findings.json` 存在於使用此 Action 的專案固定位置)加上新問題後，去除重複產生本次 Push Request 的問題表格(PR問題表格)覆蓋問題檔案

+4. 讀取來源分支中的排除問題檔案(`.gitea/ai-review/exclusions.json`)，用來過濾PR問題表格中不需要處理的問題
 5. 從PR問題表格中取出所有舊問題，依照等級排序後 Comment 到 Push Request
 6. 從PR問題表格中取出所有新問題，排除嚴重等級的問題後 Comment 到 Push Request
 7. 從PR問題表格中取出所有新問題，將每個嚴重等級的問題 Comment 到 Push Request
-8. Commit 問題檔案
-9. 如果PR問題表格中有嚴重問題，則不要讓 workflow 執行成功(exit 1)
+8. Commit 問題檔案，將 workspace 中實際存在的同步檔覆蓋到記憶區；workspace 沒有的同步檔就略過，不會刪除記憶區既有內容。自動提交的 commit message 會帶上 `[ai-review-bot]`，供 workflow 判斷是否要跳過重跑
+9. 如果 PR 問題表格中有嚴重問題，則不要讓 workflow 執行成功(exit 1)
 
 # 設計
 
-1. Gitea 的相關參數如果 inputs 沒有定義，則從 ${{ gitea.* }} 取得
+1. Gitea 相關參數中，`GITEA_TOKEN` 必須由 inputs 明確提供；`GITEA_SERVER_URL`、`GITEA_REPOSITORY`、`PR_NUMBER`、`PR_HEAD_BRANCH`、`PR_BASE_BRANCH` 等欄位若 inputs 沒有定義，則從 `${{ gitea.* }}` 取得
 2. BASE_URL 如果 inputs 沒有定義，則使用預設值
 3. Comment 加上些許 emoji 讓資訊有點活力
 4. 盡量將應用程式放在 ./app，修改 entrypoint.sh 與 Dockerfile 讓程式可以正常運行
 5. 將提示詞放到 ./app/prompts 內供程式讀取
 6. API Key 支援逗號分隔傳入多個，隨機順序各嘗試一次，全部失敗則 exit 1
-7. 讀取 Git Diff 時排除 `.gitea/` 資料夾內的所有檔案，避免 AI 分析 workflow 設定等非業務程式碼
-8. 階段五完成後驗證 `findings.json` 與 `exclusions.json` 是否為合法 JSON 格式，格式錯誤時先嘗試重置為空陣列並備份原檔，修正失敗才 exit 1
+7. 讀取 Git Diff 時排除 `.gitea/`、`.amazonq/`、`.claude/`、`.codex/`、`.gemini/`、`.github/` 資料夾，以及 `CLAUDE.md`、`GEMINI.md`、`TODO.md`、`README.md`，避免 AI 分析 workflow 設定、skill 入口與文件等非業務程式碼
+8. 階段七驗證來源分支中的 `findings.json` 與 `exclusions.json` 是否為合法 JSON 格式，格式錯誤時先嘗試透過 AI 修正內容，再重新驗證；修正後仍不合法才 exit 1；之後才檢查檔案是否存在，不存在則建立並寫入 `[]`
 9. 傳給 AI 的 findings 只保留必要欄位（level、role、location、suggestion），排除 `is_new` 等內部欄位；system prompt 精簡為指令核心；exclusions hint 只傳 location 與 suggestion，減少 token 用量
+10. 執行時會額外記錄來源分支狀態、`findings.json` / `exclusions.json` 的檔案路徑、大小、mtime 與 raw/normalized 筆數，方便追查讀檔與分支內容不一致的問題

+## Skill：Triage Findings
+
+這份 skill 用來處理 review 問題清單。
+
+### 規則
+
+1. 合併問題。
+2. 依嚴重度排序：`critical` -> `warning` -> `info`。
+3. 重新編號。
+4. 真問題就修。
+5. 誤判就加到 `.gitea/ai-review/exclusions.json`。
+6. 有變更就補測試。
+
+### 使用方式
+
+Codex：`$triage-findings 問題原始檔(文字或截圖)`
+Copilot：`/triage-findings 問題原始檔(文字或截圖)`
+Claude：直接輸入 `triage-findings 問題原始檔(文字或截圖)`
+Gemini：直接輸入 `triage-findings 問題原始檔(文字或截圖)`
+Amazon Q：直接輸入 `triage-findings 問題原始檔(文字或截圖)`
+
+### 適用情境
+
+`triage-findings 問題原始檔(文字或截圖)` 用在 review 問題整併、排序、修正、排除誤判。
+
+### 版本包含
+
+提交時一併包含 `triage-findings` skill 與各平台入口檔；已存在檔案一律覆蓋，同步到最新內容；若 workspace 沒有某個同步檔，記憶區會保留原檔，不做刪除。`findings.json` 與 `exclusions.json` 都從使用此 action 的存取庫來源分支讀取，而不是從 action 本地 workspace 讀取。寫入 `.gitea/ai-review/exclusions.json` 時，盡量保留原始問題文字的語言與語意，避免過度改寫。未來若新增任何 skill 或新增其他平台的 skill 入口，必須同時把對應檔案複製進 Docker image，並把同步清單更新到會使用此 action 的目標專案，避免 action 與目標專案內容脫節。

 ## 階段一：基本流程串接
 - 目標：確保 action 可以被觸發，pipeline 各步驟依序執行，log 出每個主要階段的進入與完成。
-- 驗收：log 中能看到每個階段（如「Step1: pipeline start」、「Step2: findings merge」等）明確訊息，且流程能走完（即使還沒產生 findings）。
-- 未驗收
+- 驗收：log 中能看到每個階段（如「Step1: Pipeline 啟動」、「Step2: Findings 產生」、「Step3: Findings 合併」等）明確訊息，且流程能走完（即使還沒產生 findings）。
+- 已驗收：`code-review` job 的 log 已完整出現 `Step1` 到 `Step8`，並以 `Pipeline 完成` 結束。
 
 ## 階段二：Git Diff 排除 .gitea/ 資料夾
-- 目標：讀取 Git Diff 時排除 `.gitea/` 資料夾內的所有檔案，避免 AI 分析 workflow 設定等非業務程式碼。
-- 驗收：PR 中有 `.gitea/` 路徑的變更時，diff 內容不包含該路徑的區塊，AI 分析結果不含 `.gitea/` 相關問題。
-- 未驗收
+- 目標：讀取 Git Diff 時排除 `.gitea/` 資料夾內的所有檔案，以及 `.amazonq/`、`.claude/`、`.codex/`、`.gemini/`、`.github/`、`CLAUDE.md`、`GEMINI.md`、`TODO.md`、`README.md`，避免 AI 分析 workflow 設定、skill 入口與文件等非業務程式碼。
+- 驗收：PR 中有上述路徑或檔案的變更時，diff 內容不包含該區塊，AI 分析結果不含這些路徑相關問題。
+- 已驗收：`app/gitea.js` 已在取得 diff 時過濾 `.gitea/` 區塊，且相關單元測試已覆蓋。
 
 ## 階段三：Findings 產生與合併
 - 目標：各角色（style/security/performance/maintainability/testing）能產生 findings，並正確合併新舊 findings。
 - 驗收：log 中能看到每個角色 findings 數量、合併後 findings 統計，並有「Step3: merged findings total=...」等訊息。
-- 未驗收
+- 已驗收：log 已顯示 5 個角色皆有分析結果，並出現 `Step3 merged findings total=13`。
 
-## 階段四：AI 去重與角色確認
-- 目標：嘗試呼叫 LLM 進行 findings 去重與角色確認，API 額度不足時要有降級處理 log。
-- 驗收：log 中能看到 deduplication/resolution confirmation 成功或失敗（如 402），降級時有「保留所有問題」等明確訊息。
-- 未驗收
+## 階段四：AI 語意去重
+- 目標：嘗試呼叫 LLM 進行 findings 語意去重，API 額度不足時要有降級處理 log。
+- 驗收：log 中能看到 `AI 去重: N -> M 筆` 的成功訊息，或在失敗時出現 `AI 去重失敗（...），降級：保留所有問題` 之類的明確訊息。
+- 已驗收：log 已出現 `AI 去重: 13 -> 11 筆`，且程式具備失敗時保留所有問題的降級處理。
 
 ## 階段五：AI 排除問題過濾
-- 目標：讀取排除問題檔案（`.gitea/ai-review/exclusions.json`）進行規則過濾，並呼叫 AI 判斷剩餘問題是否為誤報或不適用，兩層過濾後產生最終問題清單。
-- 驗收：log 中能看到排除問題檔案讀取成功或不存在的訊息、規則過濾數量變化，以及「AI 誤報過濾: N -> M 筆」或降級訊息。
-- 未驗收
+- 目標：讀取排除問題檔案（`.gitea/ai-review/exclusions.json`）時先去除重複條目、整理成語意群組摘要；若檔案不是頂層陣列格式，需主動修正成正確格式，再進行規則過濾並呼叫 AI 判斷剩餘問題是否為誤報或不適用，兩層過濾後產生最終問題清單。
+- 驗收：log 中能看到排除問題檔案讀取成功或不存在的訊息、重複排除條目的整理摘要、格式修正訊息、規則過濾數量變化，以及「AI 誤報過濾: N -> M 筆」或降級訊息。
+- 部分驗收：log 已顯示 `讀取排除問題: 50 筆` 與 `排除過濾: 11 -> 0 筆`，但這次未進入 `AI 誤報過濾: N -> M 筆` 的正向路徑。
+- 可驗收紀錄情境：當 `排除過濾` 後仍保留 1 筆以上 findings 時，log 會出現 `AI 誤報過濾: N -> M 筆`；若 API 額度不足或回傳失敗，則會出現 `AI 誤報過濾失敗（...），降級：保留所有問題`。
 
 ## 階段六：findings 寫入與 comment 發布
 - 目標：`.gitea/ai-review/findings.json` 正確寫入，comment 發布順序正確（舊問題→非嚴重→嚴重），每步有 log。
 - 驗收：log 中能看到 `.gitea/ai-review/findings.json` 寫入、comment sync 的詳細訊息與順序。
-- 未驗收
+- 部分驗收：`findings.json` 已成功寫入，也有依序執行舊問題、非嚴重、嚴重 comment 流程；但本次因結果為 0 筆，沒有實際 comment 內容可完整驗證順序。
+- 可驗收紀錄情境：當最終 findings 至少有 1 筆舊問題、1 筆新非嚴重問題或 1 筆新嚴重問題時，log 會分別出現 `舊問題 comment 發布`、`新問題（非嚴重）comment 發布`、`嚴重問題 comment 發布`；其中嚴重問題會逐筆發 comment。
 
 ## 階段七：階段六後驗證 JSON 格式
-- 目標：階段六完成後驗證 `findings.json` 與 `exclusions.json` 是否為合法 JSON 格式，格式錯誤時先嘗試重置為空陣列並備份原檔，修正失敗才 exit 1。
-- 驗收：log 中能看到兩個檔案的驗證結果（成功或失敗），格式錯誤時有「嘗試修正」訊息與備份路徑，修正失敗時 workflow 狀態為失敗。
-- 未驗收
+- 目標：階段六完成後驗證 `findings.json` 與 `exclusions.json` 是否為合法 JSON 格式，格式錯誤時先嘗試透過 AI 修正內容，再重新驗證；修正後仍不合法才 exit 1；之後才檢查檔案是否存在，不存在則建立並寫入 `[]`。
+- 驗收：log 中能看到兩個檔案的驗證結果（成功或失敗），格式錯誤時有 AI 修正嘗試與修正後再次驗證的訊息；若檔案不存在，會在驗證完成後看到建立並寫入 `[]` 的訊息；修正失敗時 workflow 狀態為失敗。
+- 已驗收：log 已明確顯示 `.gitea/ai-review/findings.json` 與 `.gitea/ai-review/exclusions.json` 都是 `JSON 格式正確`。
 
 ## 階段八：記憶區 commit/push 與錯誤處理
-- 目標：記憶區能成功 commit/push，錯誤時有明確 log，流程結束有總結訊息。
-- 驗收：log 有「persisted findings」、「commit=...」、「push=...」等訊息，錯誤時有「Runner failed: ...」等明確錯誤說明。
-- 未驗收
+- 目標：記憶區能成功 commit/push，且一併包含 `triage-findings` skill 與各平台入口檔；skill 檔案已存在時一律以來源覆蓋，workspace 沒有的同步檔則保留記憶區既有內容，不做刪除；錯誤時有明確 log，流程結束有總結訊息。
+- 驗收：log 有「persisted findings」、「commit=...」、「push=...」等訊息，且能看出 skill 相關檔案已一併提交並被來源覆蓋；當 workspace 缺少某個同步檔時，記憶區中的對應檔案不會被刪除；錯誤時有「Runner failed: ...」等明確錯誤說明。
+- 已驗收：log 已出現 `persisted findings commit=b867eaa push=feat/解決問題`，代表 commit/push 成功；本次已補上「來源覆蓋、缺檔不刪除」的同步規則，相關單元測試也已覆蓋。
 
 ## 階段九：阻擋嚴重問題 PR（第 8 點）
 - 目標：如果 PR 問題表格中有嚴重（critical）問題，workflow 需直接 exit 1，不讓流程成功。
 - 驗收：log 中能看到「critical 問題存在，workflow 結束（exit 1）」等明確訊息，且 workflow 狀態為失敗。
-- 未驗收
+- 已驗收：這次 log 已明確出現 `❌ 發現 2 個嚴重問題，workflow 結束（exit 1）`，且 job 以失敗結束，證明阻擋分支確實生效。
+- 補充紀錄：`Step8` 的退出訊息屬於預期行為，不代表 Step7 commit/push 失敗。
 
 ## 階段十：API Key 輪替
 - 目標：所有平台的 API Key 支援逗號分隔傳入多個，隨機順序各嘗試一次，單一 Key 失敗時自動換下一個，全部失敗則 exit 1。
 - 驗收：log 中能看到「key[N/M] 失敗」等訊息，換 key 後繼續執行；傳入單一 Key 時行為與原本相同；全部 Key 失敗時 log「所有 API Key 均失敗，終止流程」且 workflow 狀態為失敗。
-- 未驗收
+- 已驗收：`review.yaml` 已以逗號串接多把 Gemini key，且 `app/llm.js` 與單元測試已覆蓋輪替與失敗退出行為。
 
 ## 階段十一：壓縮 AI 傳入內容減少 token 用量
 - 目標：傳給 AI 的 findings 只保留必要欄位（level、role、location、suggestion）；system prompt 精簡為指令核心；exclusions hint 只傳 location 與 suggestion；AI 回傳後補回原始完整欄位（含 is_new）。
 - 驗收：AI 呼叫的 payload 不含 is_new 等內部欄位，去重與誤報過濾後的 findings 仍保有完整欄位供後續流程使用。
-- 未驗收
+- 已驗收：`app/findings.js` 已只傳必要欄位給 AI，並在回傳後補回原始 findings 的完整欄位。
