# Linear Core Workflow A: Issue Lifecycle

## Overview
Master issue lifecycle management: creating, updating, transitioning, and organizing issues.

## Prerequisites
- Linear SDK configured
- Access to target team(s)
- Understanding of Linear's issue model

## Instructions

### Step 1: Create Issues
```typescript
import { LinearClient } from "@linear/sdk";

const client = new LinearClient({ apiKey: process.env.LINEAR_API_KEY });

async function createIssue(options: {
  teamKey: string;
  title: string;
  description?: string;
  priority?: 0 | 1 | 2 | 3 | 4; // 0=None, 1=Urgent, 2=High, 3=Medium, 4=Low
  estimate?: number;
  labelIds?: string[];
  assigneeId?: string;
}) {
  const teams = await client.teams({ filter: { key: { eq: options.teamKey } } });
  const team = teams.nodes[0];

  if (!team) throw new Error(`Team ${options.teamKey} not found`);

  const result = await client.createIssue({
    teamId: team.id,
    title: options.title,
    description: options.description,
    priority: options.priority ?? 0,
    estimate: options.estimate,
    labelIds: options.labelIds,
    assigneeId: options.assigneeId,
  });

  if (!result.success) {
    throw new Error("Failed to create issue");
  }

  return result.issue;
}
```

### Step 2: Update Issues
```typescript
async function updateIssue(
  issueId: string,
  updates: {
    title?: string;
    description?: string;
    priority?: number;
    stateId?: string;
    assigneeId?: string;
    estimate?: number;
  }
) {
  const result = await client.updateIssue(issueId, updates);

  if (!result.success) {
    throw new Error("Failed to update issue");
  }

  return result.issue;
}

// Update by identifier (e.g., "ENG-123")
async function updateByIdentifier(identifier: string, updates: Record<string, unknown>) {
  const issue = await client.issue(identifier);
  return client.updateIssue(issue.id, updates);
}
```

### Step 3: State Transitions
```typescript
async function getWorkflowStates(teamKey: string) {
  const teams
