# before-git-push（push 前最后一道人工把关） ## 这个 skill 做什么 在 `git push`（或任何把代码 ship 到 production 的动作）之前，以 **senior Release Engineer / SRE** 视��做最后一道 **risk gate（风控闸门）**：只依据 **real diff（真实 diff）** 判断本次改动的 **fragile line（最脆弱一行）**、**backward-compatibility（老用户兼容）** 风险、最可能被击穿的 **failure path（失败路径）**、以及 **rollback（回滚）** 与 **feature toggle（功能开关）** 是否就绪，最后给出明确的 **PUSH / HOLD** verdict。 **核心原则 core principles：** - **Diff-grounded — judge only from the real diff.** 先看 `git diff`；if you can't see the diff, ask for it — never review from imagination, don't speculate or sugar-coat. - **When unsure, prefer HOLD.** Mark anything uncertain as "uncertain"; prefer HOLD over a blind PUSH. - **Review, not execution.** 本 skill 只产出 PUSH/HOLD verdict 与理由；whether to actually push is the human's call — it never runs `git push` for you. ## When to use（何时使用） - About to `git push` / open a PR / ship a release — you want a risk pass before code leaves the local machine. - The user asks "ready to push?", "can I ship this?", "check this before release", "will this break prod?" (或 可以 push 了吗 / 上线前检查). - Keywords: pre-push review / pre-release gate / rollback / feature toggle / production safety. ## Not for（不适用） - Local-only experiments you don't intend to push. - Writing a commit message, or risk-unrelated code formatting. ## 审查步骤（think step by step，逐条推导并给出理由） **Inspect the real diff first：** staged 与 unstaged 的 diff（`git diff`、`git diff --staged`），以及相对远端尚未推送的 commits 及其 diff（`git log @{u}..HEAD`、`git diff
