Constraints
- Commit, PR, and merge conventions live in
@rules/git/general.mdc— Englishtype(scope)commits, lowercase, no trailing period, no push tomain, small focused commits,Closes #issue linking, English PR titles, rebase-and-merge,ghCLI. This skill does NOT restate them. - Branch cleanup is owned by
@skills/cleanup-local-branches/SKILL.md. Defer to it; do not duplicate. - PR merging is owned by
@skills/merge-github-pr/SKILL.md. Defer to it; do not duplicate. - This skill covers only the complementary gaps below.
Use when
- Choosing or changing a branching strategy.
- Deciding merge vs rebase for a specific situation.
- Resolving a merge conflict.
- Stashing work in progress.
- Undoing a mistake (bad commit, wrong reset, accidental change).
- Cutting a release and tagging a version.
Branching strategies
GitHub Flow (simple, recommended for most)
main is always deployable. Branch from main, open a PR, merge after review and green CI, deploy. Best for SaaS and web apps with continuous deployment.
Trunk-based (high-velocity)
Everyone integrates into main via very short-lived branches (1–2 days). Incomplete work hides behind feature flags. CI must pass before merge. Needs strong CI/CD and discipline.
GitFlow (release-cycle driven)
main holds production code, develop is the integration branch, with release/* and hotfix/* branches. Heavyweight; only worth it for scheduled, regulated releases.
| Strategy | Team size | Release cadence | Best for |
|---|---|---|---|
| GitHub Flow | any | continuous | SaaS, web apps, startups |
| Trunk-based | 5+ experienced | multiple/day | high-velocity teams using feature flags |
| GitFlow | 10+ | scheduled | enterprise, regulated industries |
Default to GitHub Flow unless the team has a concrete reason for another model. It aligns with the rebase-and-merge + short-focused-branches conventions in @rules/git/general.mdc.
Merge vs rebase mechanics
Merge (preserves history)
git checkout main
git merge feature/user-auth # creates a merge commit
Use when preserving exact history matters or several people worked on the branch.
Rebase (linear history)
git checkout feature/user-auth
git fetch origin
git rebase origin/main # replays your commits on top of main
Use to update your local branch with the latest main before opening or refreshing a PR. Keeps history linear.
# only if you are the sole contributor on the branch
git push --force-with-lease origin feature/user-auth
Always --force-with-lease, never plain --force.
Pull policy: sync a side branch before pulling it
@rules/git/general.mdc Pull Policy requires every non-default branch to be rebased onto the latest default branch so it always carries the newest default-branch history. The default branch is main on some repos and master on others — resolve it instead of hardcoding origin/main (which does not exist on a master-default repo and makes the command fail). Order matters: take the branch's own remote first, then rebase the default branch in, then force-push — do not pull again afterwards.
DEFAULT_BRANCH="$(git symbolic-ref --short refs/remotes/origin/HEAD | sed 's@^origin/@@')"
git checkout feature/user-auth
git fetch origin
git pull --rebase # 1) take the branch's own remote first
git rebase "origin/$DEFAULT_BRANCH" # 2) bring the latest default branch in
# resolve conflicts if any, then: git rebase --continue
git rebase --exec 'composer check' "origin/$DEFAULT_BRANCH" # 3) verify every commit, not just the tip
git push --force-with-lease # 4) publish; do NOT git pull again — it would undo the rebase
If the rebase changed composer.lock (the default branch updated dependencies), reinstall before continuing so the installed packages match the new lockfile:
composer install # run only when composer.lock actually changed
The default branch itself is exempt — pull it directly with git pull. Read-only review skills are exempt too: they git pull only to read the diff and never rebase.
Verify a rewritten range commit by commit
@rules/git/general.mdc Git Rules (Every commit is green) requires every commit in the branch to pass the project's gate on its own, so that each one cherry-picks onto the default branch and deploys without errors. A rebase, squash, split, or reorder replays every commit onto a new base, so a green tip proves nothing about the commits underneath it — a conflict resolved in the wrong commit or a dependency that moved leaves an intermediate commit red while HEAD builds fine.
The --exec command must not modify the working tree. Pass the checking half of the gate (composer check), never the fix-and-check composer build: its @fix step rewrites tracked files, and an exec that exits 0 but leaves the tree dirty stops the rebase with execution succeeded … but left changes to the index and/or the working tree. That is a git plumbing error, not a verdict — the operator loses the signal about which commit is actually red. Run the fixers before you start the replay, not inside it.
--exec runs the gate after each replayed commit and stops at the first failure:
git rebase --exec 'composer check' "origin/$DEFAULT_BRANCH" # replay + verify each commit
# on a stop: fix the working tree, then
git add -A && git commit --amend --no-edit # repair THIS commit in place
git rebase --continue # carry on down the range
Repair the failing commit in place — never git rebase --skip past it and never append a repair commit at the tip: a repair at the tip leaves the broken commit permanently unshippable and re-creates the scattered-concern violation the reshape was meant to fix. When a commit cannot be made green alone, fold it into the commit it depends on (git rebase -i, mark it fixup) instead of publishing a red step.
Use git rebase --exec 'vendor/bin/pest tests' (or whatever faster subset the project actually defines — check composer.json scripts rather than assuming a composer test exists) while iterating, but run the full gate once before the force-push. A command that is not defined exits non-zero, and a non-zero exec stops the replay at the first commit — reporting a red history on a green range.
Never rebase shared/public history
Do NOT rebase a branch that has been pushed and that others may have based work on, nor any protected branch (main, develop), nor already-merged history. Rebase rewrites commits and breaks everyone downstream. For published branches, fix forward with git revert instead.
Conflict resolution
# 1. Trigger the conflict (or hit it during rebase/merge)
git status # lists conflicted files
# 2. Resolve each file. Conflict markers:
# <<<<<<< HEAD ... ======= ... >>>>>>> feature/user-auth
# Edit to the correct result and delete all three markers.
# Accept one whole side when appropriate:
git checkout --ours path/to/file # keep current branch version
git checkout --theirs path/to/file # keep incoming version
# 3. Stage and finish
git add path/to/file
git commit # for merge
# or
git rebase --continue # for rebase
# bail out entirely: git merge --abort / git rebase --abort
Prevention: keep branches small and short-lived, rebase onto main frequently, and coordinate before touching shared files. After resolving, re-run the project checks (see below) before continuing.
Stash workflow
git stash push -m "wip: user auth" # shelve tracked changes
git stash push -u -m "wip" # include untracked files
git stash list
git stash pop # apply newest and drop it
git stash apply stash@{2} # apply a specific stash, keep it
git stash drop stash@{0}
Undoing mistakes
# Undo the last commit, keep the changes staged
git reset --soft HEAD~1
# Undo the last commit AND discard the changes (destructive)
git reset --hard HEAD~1
# Reverse an already-pushed commit safely (public-history safe)
git revert <sha>
# Fix the last commit message
git commit --amend -m "feat(auth): correct subject"
# Add a forgotten file to the last commit (only before it is pushed)
git add forgotten-file
git commit --amend --no-edit
# Restore a single file to its committed state
git checkout HEAD -- path/to/file
Rule: reset --hard and --amend rewrite history — safe only on unpushed, local-only commits. Once pushed and shared, undo with revert.
Semantic versioning and release tagging
MAJOR.MINOR.PATCH: MAJOR for breaking changes, MINOR for backward-compatible features, PATCH for backward-compatible fixes.
git tag -a v1.2.0 -m "Release v1.2.0" # annotated tag
git push origin v1.2.0
git tag -l # list tags
git tag -d v1.2.0 && git push origin --delete v1.2.0 # remove a tag
# Draft release notes from the commit range
git log v1.1.0..v1.2.0 --oneline --no-merges

Hooks
If you wire a pre-commit or pre-push hook, run the project's own checks (the composer build / Composer scripts and the Pest suite), not ad-hoc tooling. The hook should fail the commit on any error, mirroring CI.

Done when
- A branching strategy is chosen with a stated reason.
- Merge vs rebase is applied correctly and no shared/public history was rebased.
- A non-default branch was synced (own remote pulled, then the resolved default branch rebased in, then force-pushed — never hardcoding
origin/main), andcomposer installwas re-run whenever that rebase changedcomposer.lock. - Every commit of a rewritten range was verified green with
git rebase --exec, and any failing commit was repaired in place rather than by a repair commit at the tip. - Conflicts are resolved with markers removed and project checks re-run.
- Any undo used the right tool for whether the commit was pushed.
- Releases are tagged with annotated semver tags pushed to origin.
