# Azure Service Bus SDK for TypeScript

## Overview

This public intake copy packages `plugins/antigravity-awesome-skills-claude/skills/azure-servicebus-ts` from `https://github.com/sickn33/antigravity-awesome-skills` into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the `external_source` block in `metadata.json` plus `ORIGIN.md` as the provenance anchor for review.

# Azure Service Bus SDK for TypeScript Enterprise messaging with queues, topics, and subscriptions.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Environment Variables, Authentication, Message Sessions, Dead-Letter Handling, Scheduled Messages, Message Deferral.

## When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

- This skill is applicable to execute the workflow or actions described in the overview.
- Use when the request clearly matches the imported source intent: Enterprise messaging with queues, topics, and subscriptions.
- Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
- Use when provenance needs to stay visible in the answer, PR, or review packet.
- Use when copied upstream references, examples, or scripts materially improve the answer.
- Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

## Operating Table

| Situation | Start here | Why it matters |
| --- | --- | --- |
| First-time use | `metadata.json` | Confirms repository, branch, commit, and imported path through the `external_source` block before touching the copied workflow |
| Provenance review | `ORIGIN.md` | Gives reviewers a plain-language audit trail for the imported source |
| Workflow execution | `SKILL.md` | Starts with the smallest copied file that materially changes execution |
| Supporting context | `SKILL.md` | Adds the next most relevant copied source file without loading the entire package |
| Handoff decision | `## Related Skills` | Helps the operator switch to a stronger native skill when the task drifts |

## Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. bash npm install @azure/service-bus @azure/identity ### Send Messages to Queue typescript const sender = client.createSender("my-queue"); // Single message await sender.sendMessages({ body: { orderId: "12345", amount: 99.99 }, contentType: "application/json", }); // Batch messages const batch = await sender.createMessageBatch(); batch.tryAddMessage({ body: "Message 1" }); batch.tryAddMessage({ body: "Message 2" }); await sender.sendMessages(batch); await sender.close(); ### Receive Messages from Queue typescript const receiver = client.createReceiver("my-queue"); // Receive batch const messages = await receiver.receiveMessages(10, { maxWaitTimeInMs: 5000 }); for (const message of messages) { console.log(Received: ${message.body}); await receiver.completeMessage(message); } await receiver.close(); ### Subscribe to Messages (Event-Driven) typescript const receiver = client.createReceiver("my-queue"); const subscription = receiver.subscribe({ processMessage: async (message) => { console.log(Processing: ${message.body}); // Message auto-completed on success }, processError: async (args) => { console.error(Error: ${args.error}); }, }); // Stop after some time setTimeout(async () => { await subscription.close(); await receiver.close(); }, 60000); ### Topics and Subscriptions typescript // Send to topic const topicSender = client.createSender("my-topic"); await topicSender.sendMessages({ body: { event: "order.created", data: { orderId: "123" } }, applicationProperties: { eventType: "order.created" }, }); // Receive from subscription const subscriptionReceiver = client.createReceiver("my-topic", "my-subscription"); const messages = await subscriptionReceiver.receiveMessages(10);
2. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
3. Read the overview and provenance files before loading any copied upstream support files.
4. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
5. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
6. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
7. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.

### Imported Workflow Notes

#### Imported: Installation

```bash
npm install @azure/service-bus @azure/identity
```

#### Imported: Core Workflow

### Send Messages to Queue

```typescript
const sender = client.createSender("my-queue");

// Single message
await sender.sendMessages({
  body: { orderId: "12345", amount: 99.99 },
  contentType: "application/json",
});

// Batch messages
const batch = await sender.createMessageBatch();
batch.tryAddMessage({ body: "Message 1" });
batch.tryAddMessage({ body: "Message 2" });
await sender.sendMessages(batch);

await sender.close();
```

### Receive Messages from Queue

```typescript
const receiver = client.createReceiver("my-queue");

// Receive batch
const messages = await receiver.receiveMessages(10, { maxWaitTimeInMs: 5000 });
for (const message of messages) {
  console.log(`Received: ${message.body}`);
  await receiver.completeMessage(message);
}

await receiver.close();
```

### Subscribe to Messages (Event-Driven)

```typescript
const receiver = client.createReceiver("my-queue");

const subscription = receiver.subscribe({
  processMessage: async (message) => {
    console.log(`Processing: ${message.body}`);
    // Message auto-completed on success
  },
  processError: async (args) => {
    console.error(`Error: ${args.error}`);
  },
});

// Stop after some time
setTimeout(async () => {
  await subscription.close();
  await receiver.close();
}, 60000);
```

### Topics and Subscriptions

```typescript
// Send to topic
const topicSender = client.createSender("my-topic");
await topicSender.sendMessages({
  body: { event: "order.created", data: { orderId: "123" } },
  applicationProperties: { eventType: "order.created" },
});

// Receive from subscription
const subscriptionReceiver = client.createReceiver("my-topic", "my-subscription");
const messages = await subscriptionReceiver.receiveMessages(10);
```

#### Imported: Environment Variables

```bash
SERVICEBUS_NAMESPACE=<namespace>.servicebus.windows.net
SERVICEBUS_QUEUE_NAME=my-queue
SERVICEBUS_TOPIC_NAME=my-topic
SERVICEBUS_SUBSCRIPTION_NAME=my-subscription
```

## Examples

### Example 1: Ask for the upstream workflow directly

```text
Use @azure-servicebus-ts to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
```

**Explanation:** This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

### Example 2: Ask for a provenance-grounded review

```text
Review @azure-servicebus-ts against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
```

**Explanation:** Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

### Example 3: Narrow the copied support files before execution

```text
Use @azure-servicebus-ts for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
```

**Explanation:** This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

### Example 4: Build a reviewer packet

```text
Review @azure-servicebus-ts using the copied upstream files plus provenance, then summarize any gaps before merge.
```

**Explanation:** This is useful when the PR is waiting for human review and you want a repeatable audit packet.



## Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

- Use Entra ID auth - Avoid connection strings in production
- Reuse clients - Create ServiceBusClient once, share across senders/receivers
- Close resources - Always close senders/receivers when done
- Handle errors - Implement processError callback for subscription receivers
- Use sessions for ordering - When message order matters within a group
- Configure dead-letter - Always handle DLQ messages
- Batch sends - Use createMessageBatch() for multiple messages

### Imported Operating Notes

#### Imported: Best Practices

1. **Use Entra ID auth** - Avoid connection strings in production
2. **Reuse clients** - Create `ServiceBusClient` once, share across senders/receivers
3. **Close resources** - Always close senders/receivers when done
4. **Handle errors** - Implement `processError` callback for subscription receivers
5. **Use sessions for ordering** - When message order matters within a group
6. **Configure dead-letter** - Always handle DLQ messages
7. **Batch sends** - Use `createMessageBatch()` for multiple messages

## Troubleshooting

### Problem: The operator skipped the imported context and answered too generically

**Symptoms:** The result ignores the upstream workflow in `plugins/antigravity-awesome-skills-claude/skills/azure-servicebus-ts`, fails to mention provenance, or does not use any copied source files at all.
**Solution:** Re-open `metadata.json`, `ORIGIN.md`, and the most relevant copied upstream files. Check the `external_source` block first, then restate the provenance before continuing.

### Problem: The imported workflow feels incomplete during review

**Symptoms:** Reviewers can see the generated `SKILL.md`, but they cannot quickly tell which references, examples, or scripts matter for the current task.
**Solution:** Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

### Problem: The task drifted into a different specialization

**Symptoms:** The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
**Solution:** Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.
