Create Pull Request

Draft a concise and descriptive title and a short paragraph for a PR. Explain the purpose of the changes, the problem they solve, and the general approach taken. When the changes involve clear runtime flows or state transitions, include Mermaid diagrams.

Step 1: Analyze Changes

If git is in a feature branch, examine all commit messages and the full diff to understand the overall changes. Analyze the diff for diagram opportunities (see Diagrams section below).

Step 2: Draft Title and Description

Run /github-voice to load writing style rules before drafting.

Draft a title and description, embedding any diagrams in the body. Output the drafted title and description as chat text so the user can review it.

Step 3: Confirm and Create

Use AskUserQuestion for confirmation only. Create the PR with gh pr create. Do not set --assignee unless the user explicitly asks to assign someone.

Diagrams

GitHub renders Mermaid natively in PR descriptions via ```mermaid code blocks. Include diagrams only when they add clarity a text description can't — skip for trivial changes or obvious flows.

Sequence Diagram

Include when the changes introduce or modify a clear runtime flow: API endpoints, event handlers, pipelines, multi-service interactions, webhook flows.

```mermaid
sequenceDiagram
  Client->>API: POST /payments
  API->>PaymentService: processPayment()
  PaymentService->>StripeClient: charge()
  StripeClient-->>PaymentService: confirmation
  PaymentService->>DB: save()
```

State Diagram

Include when the changes add or modify entity states, status enums, workflow transitions, or lifecycle hooks.

```mermaid
stateDiagram-v2
  [*] --> Draft
  Draft --> Pending: submit()
  Pending --> Approved: approve()
  Pending --> Rejected: reject()
  Approved --> [*]
```

Rules

• Only include when the diagram genuinely adds clarity
• Keep diagrams focused — max ~10 nodes/transitions
• Use descriptive labels on arrows (method names, HTTP verbs)
• Place diagrams after the summary paragraph under a ## Flow or ## State Machine heading
• One diagram per type max — don't include both unless the PR truly has both patterns
