umb-bump-version

name: umb-bump-version description: Bump the Umbraco CMS version across all required files. Use when the user asks to bump, update, or set the version number — e.g., "bump version to 17.3.4", "set version to 18.0.0-rc", "update version". Accepts the target version as an argument. argument-hint: (e.g., 17.3.4, 18.0.0-rc)

Bump Version - Umbraco CMS

Updates the Umbraco CMS version string across all files that track it.

Do NOT use AskUserQuestion if a version argument is provided. Only ask if $ARGUMENTS is empty or cannot be parsed as a version.

Arguments

• $ARGUMENTS - Required: the target version string (e.g., 17.3.4, 18.0.0-rc)

Files to Update

The following 5 files must be updated with the new version:

Note: For major version bumps (e.g., 17.x to 18.x), src/Umbraco.Web.UI.Login/package.json has a caret-ranged dependency on @umbraco-cms/backoffice (e.g., ^17.2.0) that will need manual updating. This skill does not handle that — major bumps involve many other changes beyond version strings.

Instructions

1. Parse and Validate the Version

Extract the version from $ARGUMENTS. It must be a valid semver-like string (e.g., 17.3.4, 18.0.0-rc, 17.4.0-preview.1). If no version is provided or it cannot be parsed, ask the user for the target version.

2. Read the Current Version

Read version.json and extract the current "version" value. If the current version already equals the target version, report that the version is already set and stop — do not edit, stage, or commit anything.

Otherwise, display both versions:

Bumping version: {current} -> {target}

3. Update All Files

Update each of the 5 files listed above, replacing the old version with the new version. For each file:

• version.json: Replace the "version" value.
• package.json files: Replace the "version" value (near the top of the file).
• package-lock.json files: Replace BOTH the top-level "version" value AND the "version" inside the "packages": { "": { ... } } block. These are always in the first ~10 lines of the file.

Use targeted edits — do NOT rewrite entire files. Be precise to avoid changing version strings in dependency entries.

4. Verify

After all edits, grep for the target version value across the 5 files to confirm all updates landed correctly:

grep -n "\"version\": \"{version}\"" version.json src/Umbraco.Web.UI.Client/package.json src/Umbraco.Web.UI.Client/package-lock.json tests/Umbraco.Tests.AcceptanceTest/package.json tests/Umbraco.Tests.AcceptanceTest/package-lock.json

Expect exactly 7 matches (one per package.json and version.json, two per package-lock.json).

5. Stage and Commit

Stage only the 5 changed files:

git add version.json src/Umbraco.Web.UI.Client/package.json src/Umbraco.Web.UI.Client/package-lock.json tests/Umbraco.Tests.AcceptanceTest/package.json tests/Umbraco.Tests.AcceptanceTest/package-lock.json

Then commit with the message Bump version to {version}. — replacing {version} with the target version:

git commit -m "Bump version to {version}."

6. Report

Output a summary:

Version bumped to {version} in:
- version.json
- src/Umbraco.Web.UI.Client/package.json
- src/Umbraco.Web.UI.Client/package-lock.json
- tests/Umbraco.Tests.AcceptanceTest/package.json
- tests/Umbraco.Tests.AcceptanceTest/package-lock.json
