description	Set up Linear credentials for Corsair. Use when the user wants to connect Linear to their agent.

Linear Key Setup

Read /add-keys first if you haven't — it explains the key model.

Auth type: api_key

• Account level: api_key (Linear API key), webhook_signature (signing secret)

---

1. Get credentials from Linear

API key (api_key)

1. Go to https://linear.app/settings/api
2. Click Create new API key
3. Name it "Corsair" → copy the key (starts with lin_api_)

Signing secret (webhook_signature)

1. Go to https://linear.app/settings/api → Webhooks
2. Create or open your webhook → copy the Signing secret

---

2. Write and run the setup script

Ask the user to provide both values, then write scripts/setup-linear.ts:

import 'dotenv/config';
import { and, eq } from 'drizzle-orm';
import { corsair } from '../server/corsair';
import { db } from '../server/db';
import { corsairAccounts, corsairIntegrations } from '../server/db/schema';

const PLUGIN = 'linear';
const TENANT_ID = 'default';
const API_KEY = 'lin_api_...';   // fill in
const SIGNING_SECRET = '...';    // fill in

async function main() {
  let [integration] = await db
    .select()
    .from(corsairIntegrations)
    .where(eq(corsairIntegrations.name, PLUGIN));

  if (!integration) {
    [integration] = await db
      .insert(corsairIntegrations)
      .values({ id: crypto.randomUUID(), name: PLUGIN })
      .returning();
    console.log(`✓ Created integration: ${PLUGIN}`);
  }

  await corsair.keys.linear.issue_new_dek();
  console.log('✓ Integration DEK ready');

  const [existing] = await db
    .select()
    .from(corsairAccounts)
    .where(
      and(
        eq(corsairAccounts.tenantId, TENANT_ID),
        eq(corsairAccounts.integrationId, integration!.id),
      ),
    );

  if (!existing) {
    await db.insert(corsairAccounts).values({
      id: crypto.randomUUID(),
      tenantId: TENANT_ID,
      integrationId: integration!.id,
    });
    console.log('✓ Created account');
  }

  await corsair.linear.keys.issue_new_dek();
  console.log('✓ Account DEK ready');

  await corsair.linear.keys.set_api_key(API_KEY);
  await corsair.linear.keys.set_webhook_signature(SIGNING_SECRET);

  const stored = await corsair.linear.keys.get_api_key();
  console.log(`✓ Linear configured. Key starts with: ${stored?.slice(0, 10)}...`);

  process.exit(0);
}

main().catch((e) => { console.error(e); process.exit(1); });

Run it:

docker compose exec agent pnpm tsx scripts/setup-linear.ts

Then delete the script:

rm scripts/setup-linear.ts
