Use when the user wants to discover and review PRs across the team awaiting their attention. NOT for a single specific PR (use review-pr). Supports three discovery modes: Label (GitHub label scan), Slack (channel-wide scan), Thread (specific Slack thread URL). Trigger: '掃 PR', 'review 大家的 PR', '批次 review', '有哪些 PR 要我看', Slack thread URL + review intent ('review <slack_url>', '幫我看這串'). Key: '我的 PR' → check-pr-approvals; '大家的 PR' / Slack URL → here; single PR URL → review-pr.
掃描使用者的 open PR，偵測 CI 狀態、未回覆 review comments、approval 數量，分類為三種狀態（可催/需修/已達標）後由使用者選擇催 review 或手動修正。Trigger: '我的 PR', 'check PR approvals', 'PR 狀態', '催 review', '催 PR', 'PR 被 approve 了嗎', '幫我掃我的 PR', '請同仁 review', '請同仁幫我 review', '請大家 review', '請大家幫我 review', '請大家幫忙看一下', '找人 review', '找誰 review', '請[人名/角色]幫我 review', '請[人名/角色]幫忙看 PR'. 主語為同仁/大家/人名/角色的「請X幫我 review」屬於催 review 範疇，不要 route 到 review-pr。
Universal planning skill: Bug reads ROOT_CAUSE then estimates; Story/Task/Epic explores codebase then splits into sub-tasks with estimates, and packs each sub-task into a self-contained task.md work order for engineering to consume. Also handles scope challenge (advisory mode). Trigger: 拆單, 'split tasks', 拆解, 'breakdown', 'break down', 子單, 'sub-tasks', 評估這張單, 'evaluate this ticket', 估點, 'estimate', 'scope challenge', '挑戰需求', 'challenge scope', '需求質疑'.
Iteratively enriches incomplete JIRA Epics into estimation-ready, technically-validated specs. Five modes: batch readiness scan, RD discovery (Phase 0), PM elaboration (Phase 1), technical approach (Phase 2), and multi-round iteration. Phase 1 goes beyond checklist filling — it explores the codebase, hardens AC, and produces a structured artifact for downstream skills. Trigger: "refinement", "grooming", "討論需求", "需求釐清", "補完 Epic", "這張單缺什麼", "brainstorm", "方案討論", "想重構", "tech debt", "batch refinement", "sprint prep", or Epic with sparse content needing enrichment.
QA agent: executes Epic AC (Acceptance Criteria) verification against an AC ticket or Epic. Runs all AC steps, classifies each as PASS/FAIL/MANUAL_REQUIRED/UNCERTAIN, and presents observed vs expected as pure facts (no root-cause judgement). On FAIL, surfaces human disposition gate (spec issue vs implementation drift); on PASS, it may transition the AC ticket to Done only after verification artifact/report is current and the shared verification contract resolves to PASS. Trigger: "驗 PROJ-123", "verify {TICKET}", "verify AC", "跑驗收", "AC 驗證". NOT for planning or implementation: implementation drift routes to refinement Bug source mode; spec issue routes back to refinement.
Canonical main-chain orchestrator for locked/current refinement-owned sources (DP-backed or JIRA Epic-backed). It routes a source through breakdown, engineering, and verify-AC without taking over their mutation authority. Trigger: "auto-pass {KEY}", "快速通關 {KEY}", "完整流程 {KEY}" when the source is LOCKED and artifacts are current. `{KEY}` 可以是 `DP-NNN` 或 JIRA Epic key。
Engineer-minded execution orchestrator: takes a planned JIRA ticket and implements it with strict quality discipline — TDD, lint, typecheck, test, behavioral verify, PR. Two modes: first-cut (new implementation) and revision (fix PR review comments by returning to the work order). Local-only workflows may register delivery extensions, but those extensions are not part of the portable skill contract. Supports batch mode via parallel sub-agents. Trigger: "做 PROJ-123", "work on", "engineering", "開始做", "接這張", "做這張", "修 PROJ-123", "fix review on PROJ-123", PR URL (from pr-pickup or direct), or user provides JIRA ticket key(s). NOT for planning: Bug → refinement Bug source mode first; Story/Task/Epic → breakdown first. Key distinction: "下一步" / "繼續" without ticket key → my-triage (zero-input router + resume scan).
Slack collaboration layer: extracts PR URLs from Slack messages and dispatches to engineering revision mode. Does NOT modify code — all code changes, GitHub review replies, and lesson extraction are engineering's responsibility. Trigger: "pr-pickup", "pickup", Slack URL + PR intent ("pickup <slack_url>", "處理 <slack_url>", "同仁貼的 <slack_url>", "接這個 PR <slack_url>"). NOT for: reviewing others' PRs (use review-pr), first-cut implementation (use engineering directly), fixing your own PR without Slack context (use engineering with ticket key or PR URL directly).
