| name | sasd-review |
| description | Generates a SA/SD (System Analysis / System Design) document for a JIRA ticket — a structured implementation plan produced before coding begins. Use this skill whenever the user mentions SASD, SA/SD, 寫 SA, 出 SA/SD, SA 文件, SD 文件, 架構文件, implementation plan, 系統分析, 系統設計, 技術設計, 異動範圍, dev scope, design doc, technical design, or asks to analyze what changes are needed for a ticket, plan the implementation approach, or produce a technical design document — even if they don't explicitly say "SA/SD".

SA/SD Review — Design-First Gate
在寫 code 前,為 JIRA ticket 產出 System Analysis / System Design 文件,先對齊需求、
異動範圍、技術方案、task estimates 與風險。
Contract
sasd-review 是 design-first gate。它產出 implementation plan,不施工、不建 branch、
不開 PR。若 ticket 已經有清楚方案,也仍需確認方向,不可直接假設。
Small change 可產 brief plan;medium scope 產 standard SA/SD;large or cross-service scope
需包含 alternatives 與 risk mitigation。

Explore sub-agent dispatch 必須注入 sub-agent-roles.md 的 Completion Envelope。Planning
decision 留在主 session;sub-agent 只提供 codebase impact evidence。
Flow
- 讀 workspace config,解析 JIRA ticket key。
- Fetch JIRA ticket,讀 summary、description、AC、PRD/design/API/discussion links。
- 依
project-mapping.md 找 target project;找不到就問使用者。
- 讀 requirements,列 ambiguities;不清楚的先問,不猜。
- 依
explore-pattern.md 探索 codebase,取得 affected files、current architecture、risks。
- 中大型 scope 提出 2-3 個 approach 與 trade-offs,請使用者確認 recommendation。
- 依 template 產出 SA/SD:requirements、dev scope、system flow、implementation design、
task list with estimates、timeline。
- 呈現給使用者調整;確認後才可寫 JIRA comment 或 Confluence page。
- External write 前跑 language gate。
Design Rules
- Task estimates 必須使用 Fibonacci scale。
- Task list 要能直接成為 breakdown input;每個 task 有 file scope 與 verification method。
- Dev scope 使用具體 file/module/service,不寫泛稱。
- 不確定的研究結論標 confidence。
- Runtime feasibility probe 需要跑環境時,使用 dedicated worktree,不污染 main checkout。
Completion
輸出 SA/SD draft、unresolved questions、chosen approach、estimated points/days、publish status、
以及建議下一步:更新 JIRA/Confluence、或進 breakdown。
