Git workflow

Git Workflow — Release-Branch Model

Enforce the release-branch Git model and help execute the correct git operations for your current context: start new work, open a PR, cut a release, or view the workflow reference.

Hard Rules (always enforced, no exceptions)

• Never commit or push directly to main. If the current branch is main, stop and create a new branch before making any changes.
• Never force-push to main.
• All changes must reach main via a PR from a release branch.

Instructions

When invoked, ask the user what they want to do (if not already specified):

"What would you like to do? (a) View the Git workflow reference (b) Start new work — scaffold a feature or fix branch (c) Open a PR for the current branch (d) Cut a release — merge release branch to main and tag (e) Resolve a merge conflict on the current branch (f) Manage stashes — list, view, apply, or drop stashes"

Then execute the appropriate action below.

---

Action (a) — View Workflow Reference

Print the full Git Workflow Reference section below.

---

Action (b) — Start New Work

1. Use Bash to identify the current release branch:

   git branch -r | grep release | sort -V | tail -1
   

   No-release-branch fallback: If the command above returns no output (no release/* branch exists), fall back to branching from main and target main for the PR. Inform the user:

   "No release branch found. Branching from main and the PR will target main directly. This is normal for simple repos and early-stage projects that do not yet use the release-branch model." In this case, replace origin/<release-branch> in step 4 with origin/main, and use --base main in the gh pr create call in Action (c).

2. Ask the user:

   • Is this a new feature or a bug fix? (determines feature/ vs fix/ prefix)
   • What is the task ID or short description? (e.g. task-042, login-crash)

3. Construct the branch name: feature/task-XXX-short-description or fix/task-XXX-short-description.

4. Use Bash to fetch the latest remote state, then create and check out the branch from the release branch:

   git fetch origin
   git checkout -b <branch-name> origin/<release-branch>
   

   Without the fetch, a stale remote-tracking ref would create the branch off an old tip.

5. Confirm the branch was created and remind the user:

   • Never commit directly to main or the release branch.
   • Open a PR from this branch into the release branch when work is complete.

---

Action (c) — Open a PR

1. Use Bash to check the current branch and recent commits:

   git branch --show-current
   git log --oneline -10
   

2. Use Glob to check if handoffs/reviews/ exists. If it does, use Read on any open review artifacts to check for unresolved findings with severity: critical | severe | moderate. If any exist, block the PR and inform the user these must be resolved first.

3. Use Bash to identify the target release branch:

   git branch -r | grep release | sort -V | tail -1
   

4. Use Read to check handoffs/plans/ for context to include in the PR description.

5. Produce a PR description with: summary of changes, related task IDs, testing notes. Then use Bash:

   gh pr create --title "<title>" --body "<description>" --base <release-branch>
   

   If gh is not available, print the PR body for the user to paste manually.

---

Action (d) — Cut a Release

1. Use Bash to confirm the current release branch is clean and all PRs are merged:

   git status
   git log --oneline origin/main..HEAD
   

2. Ask the user for the version tag (e.g. 1.0.0).

3. Open a release PR from the release branch into main — all changes reach main via PR, including releases:

   gh pr create --base main --head release/<version> --title "Release v<version>" --body "<release summary>"
   

   If gh is not available, print the PR body and ask the user to open the PR manually.

4. After the PR is approved and merged, tag the release on main. Confirm before pushing the tag:

   git checkout main
   git pull origin main
   git tag v<version>
   git push origin v<version>
   

5. Remind the user to invoke /abd-docs (or the Documentation agent) to create the changelog for this release in docs/CHANGELOG.md or docs/changelogs/<version>.md.

---

Action (e) — Resolve a Merge Conflict

1. Use Bash to identify all conflicted files:

   git status
   

   List each file that shows both modified, deleted by us, deleted by them, or any other conflict marker.

2. Use Bash to fetch the latest remote state and show how far behind the current branch is:

   git fetch origin
   git log --oneline HEAD..origin/$(git branch --show-current)
   

   Report how many commits the remote is ahead. If the remote branch no longer exists, note that and continue with local conflict resolution.

3. Ask the user whether to rebase or merge to incorporate upstream changes, and explain the tradeoffs:

   • Rebase (git rebase origin/<branch>): rewrites your local commits on top of the upstream tip, producing a linear history. Best for feature branches that are not shared with others. Avoid rebasing branches that other people have checked out.
   • Merge (git merge origin/<branch>): creates a merge commit that preserves the full history of both sides. Safer for shared or long-lived branches where rewriting history would disrupt collaborators.

   Wait for the user's choice before proceeding.

4. For each conflicted file identified in step 1: a. Use Read to display the file and locate the conflict markers (<<<<<<<, =======, >>>>>>>). b. Explain to the user what each side of the conflict contains:

   • HEAD (your changes): the lines between <<<<<<< HEAD and =======.
   • Incoming (their changes): the lines between ======= and >>>>>>> <ref>. c. Ask the user which resolution to apply (keep yours, keep theirs, or combine), or propose a resolution if the intent is clear from context. d. Use Edit to apply the agreed resolution, removing all conflict markers so the file is valid.

5. After all conflicted files are resolved, use Bash to stage only the resolved files by name (never git add ., which would sweep untracked files like build output or .env into the commit) and complete the rebase or merge:

   • If rebase was chosen:

     git add <resolved-file-1> <resolved-file-2> ...
     git rebase --continue
     

     If additional conflict rounds occur, repeat steps 4–5 for each round until the rebase completes.
   • If merge was chosen:

     git add <resolved-file-1> <resolved-file-2> ...
     git merge --continue
     

6. Use Bash to confirm the branch is clean and ready to push:

   git status
   git log --oneline -5
   

   Verify there are no remaining conflict markers and the working tree is clean. Remind the user:

   • If rebase was used, a force-push is required: git push --force-with-lease origin <branch>. Only do this if the branch is not shared.
   • If merge was used, a regular push is safe: git push origin <branch>.

Action (f) — Manage Stashes

1. Use Bash to list all stashes:

   git stash list
   

   If the list is empty, inform the user and stop.

2. Show the stash list to the user and ask what they want to do:

   "(i) Inspect a stash — show its diff (ii) Apply a stash — apply without dropping (iii) Pop a stash — apply and drop (iv) Drop a stash — delete without applying (v) Drop all stashes — clear the entire stash list (confirm first)"

3. Execute the chosen sub-action:

   Sub-action (i) — Inspect a stash

   Ask the user which stash number (N) to inspect. Then:

   git stash show -p stash@{N}
   

   Display the diff and provide a plain-language summary of what changes are stashed (files changed, nature of changes).

   Sub-action (ii) — Apply a stash

   Ask the user which stash number (N) to apply. Then:

   git stash apply stash@{N}
   

   After applying, check for conflicts:

   git status
   

   If any conflicts are present (files show both modified or similar), inform the user and run Action (e) to resolve them.

   Sub-action (iii) — Pop a stash

   Ask the user which stash number (N) to pop. Then:

   git stash pop stash@{N}
   

   After popping, check for conflicts the same way as sub-action (ii). If conflicts are found, run Action (e) to resolve them.

   Sub-action (iv) — Drop a stash

   Ask the user which stash number (N) to drop. Show the stash message and confirm:

   "This will permanently delete stash@{N}: <message>. Confirm? (y/n)"

   If confirmed:

   git stash drop stash@{N}
   

   Sub-action (v) — Drop all stashes

   Count the total number of stashes and confirm with the user:

   "This will permanently delete ALL X stashes. This cannot be undone. Confirm? (y/n)"

   If confirmed:

   git stash clear
   

4. After any sub-action completes, run git stash list again and show the user the updated stash state.

Git Workflow Reference

Branch Model

Branch	Purpose	Rules
main	Production-ready history	Never commit directly. Only merge from release branches.
release/<version>	Integration branch per release	Never commit directly. All feature/fix PRs target this.
feature/task-XXX-description	New work	One per task. Created from the release branch.
fix/task-XXX-description	Bug fixes	One per issue. Created from the release branch.

Flow

feature/* or fix/*
       ↓  (PR)
release/<version>
       ↓  (PR when release is ready)
      main  →  tag v<version>

Who Does What

Action	Responsible
Create feature/fix branch	Planning or Dev agent
Open PR	Dev agent (the one that did the work)
Code review	Tech Review + Security agents
Approve PR	Tech Review + Security; Planning after triage
Merge to release	Planning or designated agent
Cut release (release → main + tag)	Planning or DevOps
Create changelog	Documentation agent

Naming Conventions

• Feature branches: feature/task-NNN-short-description
• Fix branches: fix/issue-NNN-short-description
• Version tags: vMAJOR.MINOR.PATCH (e.g. v1.0.0)
• Changelog: docs/CHANGELOG.md or docs/changelogs/<version>.md

Merge Style

Document the chosen merge style in docs/assumptions.md at project start. Default: merge commit (--no-ff) to preserve branch history.

Changelogs

The Documentation agent creates or updates changelogs in docs/ for each release. Format: version, date, sections for Added / Changed / Fixed / Security, links to PRs or handoff artifacts.

Output Format

After completing any action, confirm:

• What git operations were run (list commands with output).
• The current state of relevant branches.
• What the next step is.
