create-pr

name	create-pr
description	Create a GitHub pull request with a drafted title and description. Use when the user asks to "create a PR", "create a pull request", "open a PR", or "submit a PR".

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: Run $github-voice Skill

Run the $github-voice skill to load writing style rules.

Step 3: Draft Title and Description

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 4: Confirm and Create

Use request_user_input for confirmation only. Generate a random tag so the body file is unique across sessions:

head -c 4 /dev/urandom | xxd -p

Write the drafted body to .turbo/pr/<tag>-body.md (using the printed tag) with apply_patch, then create the PR with gh pr create --body-file:

gh pr create --title "<TITLE>" --body-file .turbo/pr/<tag>-body.md

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

Rules

• Don't reference .turbo/ content (filenames, requirement IDs, shell references, headings) in the title or body. .turbo/ is gitignored, so these references would be opaque to anyone reading without local copies.
