Pm Pr Workflow

PR Workflow and Branch Protection

Branch Protection Enforcement

CRITICAL: PM must enforce branch protection for main branch.

Detection (run before any main branch operation)

bashCopy code
git config user.email

Routing Rules

• User is bobmatnyc@users.noreply.github.com → Can push directly to main (if explicitly requested)
• Any other user → MUST use feature branch + PR workflow

User Request Translation

When non-privileged users request main branch operations:

Error Prevention: PM proactively guides non-privileged users to correct workflow (don't wait for git errors).

Worktree-First Branch Setup

Check workflow.worktree.enabled (default: true) before starting any issue branch.

When enabled (default)

Replace the plain branch checkout with a git worktree:

bashCopy code
# Create the worktree and branch in one step
git worktree add .claude/worktrees/issue-N-<slug> -b feat/N-<slug>

# All engineering work happens inside the worktree
cd .claude/worktrees/issue-N-<slug>

The source directory (repo/) stays on main throughout; only the worktree directory advances on the feature branch.

Post-merge cleanup (after squash-merge lands on main):

bashCopy code
# Remove the worktree
git worktree remove .claude/worktrees/issue-N-<slug>
git branch -d feat/N-<slug>   # delete the local tracking branch

# Pull latest main in the source dir
git pull

• Only run after confirming the squash-merge has landed on main.
• If the worktree has untracked files git will refuse removal — inspect with git -C .claude/worktrees/issue-N-<slug> status first.
• After inspecting: commit or stash any work you want to keep, then retry git worktree remove; or use --force only if you are certain the files are disposable.

When disabled (opt-out)

Set workflow.worktree.enabled: false in .claude-mpm/config.yaml to fall back to the standard branch checkout approach below:

bashCopy code
git checkout -b feat/N-<slug>

PR Workflow Delegation

Default: Main-based PRs (unless user explicitly requests stacked)

When User Requests PRs

• Single ticket → One PR (no question needed)
• Independent features → Main-based (no question needed)
• User says "stacked" or "dependent" → Stacked PRs (no question needed)

Recommend Main-Based When

• User doesn't specify preference
• Independent features or bug fixes
• Multiple agents working in parallel
• Simple enhancements

Recommend Stacked PRs When

• User explicitly requests "stacked" or "dependent" PRs
• Large feature with clear phase dependencies
• User is comfortable with rebase workflows

Always delegate to version-control agent with strategy parameters.

PR Creation Workflow

Footer Branding (required)

Always append the canonical MPM footer to PR bodies and commit messages:

Copy code
🤖👥 Generated with [Claude MPM](https://github.com/bobmatnyc/claude-mpm)

Never use Claude Code's default 🤖 Generated with [Claude Code] footer. MPM only overrides the commit trailer (Co-Authored-By), so the "Generated with" footer must be set explicitly to the canonical MPM string — otherwise the Claude Code default leaks into GitHub PRs and issues. The Co-Authored-By: Claude MPM <https://github.com/bobmatnyc/claude-mpm> trailer is separate and stays as-is.

When creating PRs, delegate to version-control agent with:

Copy code
Task:
  agent: "version-control"
  task: "Create PR for {feature}"
  context: |
    Work completed: {summary}
    Files changed: {file_list}
    Tests: {test_status}
    QA verification: {qa_evidence}
  acceptance_criteria:
    - Create feature branch from main
    - Push all commits to feature branch
    - Create PR with proper description
    - Link ticket if applicable
    - Request reviews if needed

Code Review (If Available)

After the PR is created and CI passes, the PM checks whether trusty-review is available before proceeding to squash-merge.

Availability Check

Call mcp__trusty-review__review_health. Treat trusty-review as available if and only if:

• status == "ok" AND
• reviewer_model is set (non-empty string)

If the health call throws an exception, returns a non-ok status, or returns an empty reviewer_model, skip the review step entirely — never block or warn the user about trusty-review being unavailable.

Note: Once the upstream health endpoint exposes an inference field, also require inference == "ok" as part of the availability check.

When Available

The PM calls mcp__trusty-review__review_pr(owner, repo, pr_number) directly (PM has MCP tool access). Route the verdict as follows:

When Unavailable

Skip silently. Do not surface any message to the user about trusty-review being down. The PR workflow continues to squash-merge as normal.

Common Patterns

Single Feature PR

bashCopy code
# Feature branch → PR → Main
feature/user-auth → PR #123 → main

Stacked PRs (when requested)

bashCopy code
# Stacked feature development
feature/auth-base → PR #123 → main
feature/oauth (based on auth-base) → PR #124 → feature/auth-base
feature/session (based on oauth) → PR #125 → feature/oauth

Bug Fix PR

bashCopy code
# Hotfix branch → PR → Main
fix/login-error → PR #126 → main

Branch Protection Checklist

Before any main branch operation:

• Check git user email
• Verify user has main branch access
• If not privileged user, route to feature branch workflow
• Create clear user messaging about branch protection

Integration with Git File Tracking

All file tracking should happen on feature branches before PR creation:

1. Agent creates files
2. PM tracks files immediately (git add + commit)
3. PM delegates PR creation to version-control
4. version-control pushes branch and creates PR

This ensures all work is tracked before entering PR workflow.
