GitHub Scrum Flow

Overview

This skill consolidates the responsibilities of a Scrum Master and Release Manager. It is the single source of truth for:

1. Project Orchestration: Synchronizing plan.md tracks with GitHub Issues.
2. Git Hygiene: Enforcing strict branching, commit, and merging standards.
3. Status Reporting: Managing the lifecycle of tasks via the gh CLI.

Core Mandates

1. The "Golden Thread" (Issue <-> Track <-> Branch)

Every unit of work must trace back to a source of truth:

• GitHub Issue: The stakeholder view (What & Why).
• Conductor Track (plan.md): The engineering view (How).
• Git Branch: The implementation workspace.

Rule: You generally do not start coding without a Branch, and you do not start a Branch without a plan item (and ideally a linked Issue).

2. GitHub Flow Enforcement

• No Direct Commits or Merges to Main: main is sacred and deployable. The agent MUST NOT merge branches to main locally. All code must go through a Pull Request.
• PR-First Workflow: Every track or significant change requires a Pull Request created via gh pr create.
• Short-Lived Branches: Branches should live for hours or days, not weeks.
• Atomic Commits: One logical change per commit.
• Strict Naming: Branches and commits must follow conventions.

3. Professional Visibility

• Updates to GitHub Issues must be concise, professional, and frequent enough to show heartbeat, but not noisy.
• Use gh CLI for all issue interactions to ensure audit trails.

Procedures

Phase 1: Initialization (Start of Task/Track)

Trigger: When starting a new track or task from plan.md.

1. Sync with GitHub Issue:
   • If a track corresponds to a GitHub Issue, post the plan summary.
   • gh issue comment <issue_id> --body "Starting work on Track <track_id>. Plan summary: ..."
2. Establish Context:
   • Ensure your local main is up to date: git checkout main && git pull origin main
3. Create Branch:
   • Name format: <type>/<short-description>-<issue_id>
   • Types:
     • feat: New features
     • fix: Bug fixes
     • chore: Maintenance/Config
     • refactor: Code restructuring
     • docs: Documentation
     • test: Adding tests
   • Example: git checkout -b feat/inventory-ledger-123

Phase 2: Implementation (The Loop)

Trigger: During active coding.

1. Scope Management:
   • If work drifts outside the branch name's scope (e.g., fixing a UI bug while in feat/api-auth), STOP.
   • Stash changes, switch to main, create a new fix/... branch, or log it as a new task.
2. Status Updates:
   • Post to GitHub Issue on: Blockers, Major Architectural Decisions, or Phase Completion.
   • gh issue comment <issue_id> --body "Update: [Topic]. Summary: ..."
3. Commit Protocol:
   • Stage only relevant files.
   • Format: type(scope): description (e.g., feat(auth): implement jwt validation).

Phase 3: Verification & Closure

Trigger: When a task or track is marked [x].

1. Final Verification:
   • Ensure all tests pass.
   • Ensure pnpm lint and pnpm type-check pass.
2. Pull Request Submission:
   • MANDATORY: Push the branch and create a PR. Do NOT merge locally.

     git push origin <branch_name>
     gh pr create --title "Track <track_id>: <Title>" --body "Closes #<issue_id>. Verification: [Evidence]"
     

3. Issue Handover:
   • Inform the user that the PR is ready for review and merge.
   • Do NOT delete the branch until the PR is merged (usually by the user or CI).

Reference: CLI Cheatsheet

GitHub (gh)

• List Issues: gh issue list
• View Issue: gh issue view <id>
• Comment: gh issue comment <id> --body "..."
• Close: gh issue close <id>
• Create PR: gh pr create --title "..." --body "..."

Git

• New Branch: git checkout -b <name>
• Delete Branch: git branch -d <name>
• Log (One Line): git log --oneline -n 10
• Status: git status
