apply-semantic-versioning
About
This skill analyzes code changes to determine the correct semantic version bump (major/minor/patch) following SemVer 2.0.0. It handles breaking change detection, pre-release identifiers, and build metadata for release preparation. Use it after merging changes to resolve version disagreements or before tagging releases.

施 SemVer
由變析定正版升。析變、分主/次/補、算新版、更檔。循 SemVer 2.0.0。
用
- 備新發須定正版號→用
- 合變後標前→用
- 評變為破否→用
- 加預發識(alpha、beta、rc)→用
- 解版升爭→用
入
- 必:項根含版檔(DESCRIPTION、package.json、Cargo.toml、pyproject.toml、或 VERSION)
- 必:自末發以來之 git 史
- 可:用之提例(規範提交、自由)
- 可:欲加預發標
- 可:前版若不可自檔讀
行
一:讀今版
於項根尋讀版檔。
# R packages
grep "^Version:" DESCRIPTION
# Node.js
grep '"version"' package.json
# Rust
grep '^version' Cargo.toml
# Python
grep 'version' pyproject.toml
# Plain file
cat VERSION
析今版為 major.minor.patch。版含預發後綴(如 1.2.0-beta.1)→獨記。
得:今版識為 MAJOR.MINOR.PATCH[-PRERELEASE]。
敗:無版檔→察 VERSION 或 git 標(git describe --tags --abbrev=0)。全無版→初發用 0.1.0,穩公 API 用 1.0.0。
二:析末發以來之變
取自末標以來諸變。
# Find the last version tag
git describe --tags --abbrev=0
# List commits since that tag
git log --oneline v1.2.3..HEAD
# If using Conventional Commits, filter by type
git log --oneline v1.2.3..HEAD | grep -E "^[a-f0-9]+ (feat|fix|BREAKING)"
無標→比於初提或知基。
得:諸提附訊可分變類。
敗:git 史不可達或標缺→請開發者述變。按述分。
三:分變
施 SemVer 分律:
| Change Type | Version Bump | Examples |
|---|---|---|
| Breaking (incompatible API change) | MAJOR | Renamed/removed public function, changed return type, removed parameter, changed default behavior |
| Feature (new backwards-compatible functionality) | MINOR | New exported function, new parameter with default, new file format support |
| Fix (backwards-compatible bug fix) | PATCH | Bug fix, documentation correction, performance improvement with same API |
分律:
- 任變為破→升 MAJOR(次與補歸零)
- 無破而任新功→升 MINOR(補歸零)
- 唯修→升 PATCH
特例:
- <1.0.0:初發(
0.x.y)次升或含破。明文 - 棄用:棄函(仍行)為 MINOR。去之為 MAJOR
- 內變:不改公 API 之重構為 PATCH
得:各變分為破/功/修,全升階定。
敗:變含糊→傾高升。保守主升勝破下游碼之次升。
四:算新版
施升於今版:
| Current | Bump | New Version |
|---|---|---|
| 1.2.3 | MAJOR | 2.0.0 |
| 1.2.3 | MINOR | 1.3.0 |
| 1.2.3 | PATCH | 1.2.4 |
| 0.9.5 | MINOR | 0.10.0 |
| 2.0.0-rc.1 | (release) | 2.0.0 |
請預發標:
1.3.0-alpha.1為將 1.3.0 之首 alpha1.3.0-beta.1為首 beta1.3.0-rc.1為首發候
預發序:alpha < beta < rc < (發)。
得:新版號循 SemVer 算。
敗:今版形誤或非 SemVer→先正規。如 1.2 為 1.2.0。
五:更版檔
書新版於相關檔。
# R: Update DESCRIPTION
# Change "Version: 1.2.3" to "Version: 1.3.0"
// Node.js: Update package.json
// Change "version": "1.2.3" to "version": "1.3.0"
// Also update package-lock.json if present
# Rust: Update Cargo.toml
# Change version = "1.2.3" to version = "1.3.0"
項有多檔涉版(如 _pkgdown.yml、CITATION、codemeta.json)→皆更。
得:諸版檔一致更為新版號。
敗:檔更敗→撤諸變保一致。永勿留版檔半更態。
六:建版標
提版升後建 git 標。
# Annotated tag (preferred)
git tag -a v1.3.0 -m "Release v1.3.0"
# Lightweight tag (acceptable)
git tag v1.3.0
用項標例:
v1.3.0(最常)1.3.0(無前綴)[email protected](單庫多項)
得:git 標配新版。
敗:標已存→版未正升。以 git tag -l "v1.3*" 察重標解之再進。
驗
- 今版自正版檔讀
- 末發以來諸提皆析
- 各變分為破、功、修
- 升階配最高嚴變(破 > 功 > 修)
- 新版循 SemVer 2.0.0 式:
MAJOR.MINOR.PATCH[-PRERELEASE][+BUILD] - 項諸版檔一致更
- 無版跳(如 1.2.3 至 1.4.0 而 1.3.0 未發)
- git 標配新版與項標式
- 預發後綴若用循正序(alpha < beta < rc)
忌
- 跳次版:自 1.2.3 直至 1.4.0「以加二功」。各發一升;功數不定版
- 棄用為破:棄函(加警)為次。唯去為破
- 忘 <1.0.0 律:1.0.0 前 API 視為不穩。某項此期次升或破,當文
- 版檔不一致:更 package.json 而非 package-lock.json,或更 DESCRIPTION 而非 CITATION。諸版引須同
- 建元混:建元(
+build.123)不影版序。1.0.0+build.1與1.0.0+build.2同序 - 不標發:無 git 標,後版升不能定變析基
