Linear issues flow through typed workflow states (`triage` -> `backlog` -> `unstarted` -> `started` -> `completed` | `canceled`), belong to a team, and support priorities 0-4, estimates, due dates, labels, and cycle/project assignment. ## Prerequisites - `@linear/sdk` installed with API key or OAuth token configured - Access to target team(s) - Understanding of your team's workflow states ## Instructions ### Step 1: Create Issues ```typescript import { LinearClient } from "@linear/sdk"; const client = new LinearClient({ apiKey: process.env.LINEAR_API_KEY! }); // Get team const teams = await client.teams(); const team = teams.nodes.find(t => t.key === "ENG") ?? teams.nodes[0]; // Basic issue const result = await client.createIssue({ teamId: team.id, title: "Implement user authentication", description: "Add OAuth 2.0 login flow with Google and GitHub providers.", priority: 2, // 0=None, 1=Urgent, 2=High, 3=Medium, 4=Low }); if (result.success) { const issue = await result.issue; console.log(`Created: ${issue?.identifier} — ${issue?.title}`); console.log(`URL: ${issue?.url}`); } // Issue with full metadata const labelResult = await client.issueLabels({ filter: { name: { eq: "Bug" } } }); const bugLabel = labelResult.nodes[0]; const states = await team.state...
