⚠️ MANDATORY: Issue Linking

Every PR MUST link to related issues and use closing keywords.

• PRs without issue links are incomplete
• Use Closes #X or Fixes #X to auto-close issues on merge
• Reference ALL related issues, even if not closing them

Instructions

Step 1: Identify Related Issues

# Check current branch name for issue hints
git branch --show-current

# Search for related issues
gh issue list --search "relevant keywords"

# View specific issue
gh issue view <number>

Find ALL issues this PR addresses:

• Issues explicitly being fixed
• Issues partially addressed
• Related issues for context

Step 2: Gather Context

# See what changed
git log main..HEAD --oneline
git diff main..HEAD --stat

# Get commit messages for context
git log main..HEAD --format="%s%n%b"

Step 3: Create PR with Issue Links

Use the writing-clearly-and-concisely skill for clear writing, then follow pr_guide.

IMPORTANT: Do NOT include "Generated with Claude Code" or similar tool attribution footers in PR descriptions.

gh pr create --title "[type]: [emoji] [description]" --body "$(cat <<'EOF'
[Two-sentence summary of what and why]

## Key Changes
- [Change 1]
- [Change 2]

## Related Issues

**Closes:**
- Closes #X - [brief description of what's fixed]
- Closes #Y - [brief description]

**Related (not closing):**
- Related to #Z - [why related]
- See also #W - [context]

## Testing
- [How it was tested]

## Files Changed
- [List key files]
EOF
)"

Issue Linking Keywords

GitHub recognizes these keywords to auto-close issues on merge:

Keyword	Example	Effect
Closes	Closes #123	Closes issue when PR merges
Fixes	Fixes #123	Closes issue when PR merges
Resolves	Resolves #123	Closes issue when PR merges

Use format: Closes #X - brief description

Step 4: Verify Issue Links

After creating PR:

# Verify the PR shows linked issues
gh pr view <number> --json closingIssuesReferences

# Check the issue shows the PR link
gh issue view <number>

PR Description Template

[Two-sentence summary: what changed and why it was needed]

## Key Changes
- [Most important change]
- [Second important change]
- [Third important change]

## Related Issues

**Closes:**
- Closes #X - [what requirement this addresses]
- Fixes #Y - [what bug this fixes]

**Related:**
- Related to #Z - [provides context but doesn't close]

## Testing
- [Manual testing performed]
- [Automated tests added/passing]

## Architectural Impact
[If significant: explain system-wide effects]

## Files Changed
- `path/to/file1.ts` - [what changed]
- `path/to/file2.ts` - [what changed]

Anti-Patterns

❌ WRONG:
gh pr create --title "Fix bug" --body "Fixed the thing"

❌ WRONG:
"Related: #123" (no closing keyword, issue won't close)

❌ WRONG:
No mention of any issues at all

✅ CORRECT:
gh pr create --title "fix: 🔧 Resolve auth token expiration" --body "
Fixes session timeout by implementing token refresh.

## Related Issues
- Closes #123 - Auth token expires incorrectly
- Closes #124 - Users logged out unexpectedly
- Related to #100 - Auth system overhaul (partial)

Mermaid Diagrams in PRs

Use Mermaid diagrams to visualize changes, flows, and architectural impacts.

GitHub renders Mermaid natively. Include diagrams when:

• Showing before/after state changes
• Illustrating new data flows
• Explaining component interactions
• Depicting architectural changes

When to Include Diagrams

PR Type	Diagram Use
Bug fix	Before/after flow showing fix
New feature	User journey or data flow
Refactor	Component dependency changes
API changes	Request/response sequence

Example: PR with Diagram

## Key Changes

Added token refresh flow when session expires.

### New Authentication Flow

```mermaid
sequenceDiagram
    participant C as Client
    participant A as Auth Service
    participant D as Database

    C->>A: Request with expired token
    A-->>C: 401 Token Expired
    C->>A: POST /refresh with refresh_token
    A->>D: Validate refresh token
    D-->>A: Token valid
    A-->>C: New access token
    C->>A: Retry original request
    A-->>C: 200 Success
```

## Related Issues
- Closes #123 - Token expiration handling

Diagram Types for PRs

## Flow changes: flowchart
## API interactions: sequenceDiagram
## State machines: stateDiagram-v2
## Data models: erDiagram

Tips:

• Keep diagrams focused (5-10 nodes)
• Show the change, not entire system
• Before/after pairs are powerful
• Embed in PR body, not as links

Quick Reference

1. Find issues: gh issue list --search "keywords"
2. Create PR with closing keywords: Closes #X, Fixes #X
3. Always include: Related Issues section in PR body
4. Verify: gh pr view --json closingIssuesReferences
5. Add Mermaid diagrams for complex changes
