2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Use when analyzing TYPO3 Forge issues, submitting patches to Gerrit, contributing core bug fixes, documentation contributions, cherry-pick workflows, or CI debugging on Gerrit. Core `main` branch is v15-in-progress (PHP 8.4/8.5); v14.3 LTS bugfixes land on branch `14.3` and are backported via cherry-pick.

TYPO3 Core Contributions

Guide for contributing to TYPO3 Core: Forge issues, Gerrit patches, CI debugging, and review workflows.

When to Use

Forge issue analysis or creation (forge.typo3.org/issues/*)
Patch submission, CI debugging, Gerrit review workflow
Commit message formatting, cherry-picks, rebasing

Prerequisites

Run ${CLAUDE_SKILL_DIR}/scripts/verify-prerequisites.sh to check: TYPO3.org account, Gerrit SSH (ssh -p 29418 <user>@review.typo3.org), Git email matching Gerrit. See references/account-setup.md.

Workflow

Setup: Account + environment (${CLAUDE_SKILL_DIR}/scripts/setup-typo3-coredev.sh, references/ddev-setup-workflow.md)
Branch: git checkout -b feature/<issue>-description
Analyze: Understand root cause, reproduction steps, affected versions before coding
Develop: Implement fix + tests, validate with typo3-conformance-skill
Commit: Follow format below, include Resolves: #<issue> + Releases:
Push: git push origin HEAD:refs/for/main (starts as WIP)
CI: Wait for all jobs. Read actual GitLab logs at git.typo3.org/typo3/CI/cms/-/jobs/<id>. Fix ALL failures in one amend+push
Ready: Mark ready via git push origin HEAD:refs/for/main%ready or Gerrit UI "Start Review"
Review: Address feedback, amend commit, preserve Change-Id. Fetch reviewer's patchset first to preserve their message edits: git fetch origin refs/changes/XX/NNNNN/N && git reset --soft FETCH_HEAD
Update: git commit --amend && git push origin HEAD:refs/for/main

Commit Format

[TYPE] Subject (imperative mood, max 52 chars)

How and why (not what). Wrap at 72 chars.

Resolves: #12345
Releases: main, 13.4, 12.4

Types: [BUGFIX], [FEATURE] (main only), [TASK], [DOCS], [SECURITY] Breaking: [!!!][TYPE] prefix, Releases: main only Required: Every commit MUST have Resolves: (not just Related:)

CI Debugging

Read ALL failing job logs (never guess). Common jobs: cgl pre-merge (code style), phpstan (static analysis), unit/functional (tests). Fix all in one patchset. Local checks:

./Build/Scripts/runTests.sh -s unit && ./Build/Scripts/runTests.sh -s functional
./Build/Scripts/cglFixMyCommit.sh
./Build/Scripts/runTests.sh -s phpstan
