## What it does

A topic in Celigo is a named message channel. One flow publishes records, any number of others read them, each from its own position. A message stays readable until the retention window ends, read or not.

The skill walks through the steps by number: creating and registering a topic, fields like `retentionMs` and `externalId`, the license and its quotas, the publisher step (`adaptorType: "TopicImport"`) and the listener step (`adaptorType: "TopicExport"`, `type: "stream"`), publishing, reading and purging messages, listener positions, diagnosing a listener that never runs, deleting and restoring. The exact calls depend on how you reach the account: the deployed Celigo MCP server has no topic tools, so creating, registering, publishing, reading, purging and deleting go through the CLI, the UI or the REST API, while the skill points to `references/mcp.md` and `references/cli.md`.

Publishing reaches every flow subscribed to the topic, and purging deletes every retained message for good. The skill tells you to confirm both with the user first. One thing to check before you start: without the Event Streams entitlement a topic write fails with `topics_subscription_required`, and the quota is only checked when a topic is created or restored, so nothing warns you as the account approaches the limit.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-topics -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/configuring-topics/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/configuring-topics/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-topics -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/configuring-topics/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-topics -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/configuring-topics/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install celigo/ai configuring-topics
```

2. **Manually: put the files in place**
- File: `.github/skills/configuring-topics/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-topics -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/celigo/ai --path skills/configuring-topics
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/configuring-topics/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill configuring-topics -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/celigo/ai/tree/HEAD/skills/configuring-topics/SKILL.md

## When to use it
- create a topic and register it on the integrations that need it
- wire a publisher and a listener to the same topic
- read retained messages without moving a listener's position
- find out why a listener never runs
- delete a topic or restore it from the recycle bin

## Example prompts
- create a topic with a 7-day retentionMs and register it on this integration
- add a publisher step with adaptorType TopicImport for this topic
- show the listener positions and tell me why one of them never runs

description: Configure Celigo Event Streams topics -- durable message channels that let one flow publish records and any number of other flows consume them, each from its own position. Covers creating and registering topics, retention and licensing, publisher and listener steps, publishing, reading and purging messages, listener positions, and delete rules. Use when creating or registering a topic, wiring a topic publisher or listener, publishing or inspecting messages, diagnosing a listener that never runs, or deleting a topic.

# Configuring Topics (Event Streams)

A topic is a **named, durable message channel**. Publishers append messages; every listener receives all of them, reading from its own position at its own pace; and a message stays readable until the topic's retention window ends, whether or not anything read it. A topic decouples the flow that produces an event from the flows that consume it: add a consumer without touching the producer, pause one consumer while the others carry on, and let it catch up from where it stopped.

A topic is an account resource that lives in one environment, outside any integration -- like a lookup cache. Flows use it through two steps, neither of which takes a connection:

- **Publisher** -- an import with `adaptorType: "TopicImport"`. Every record it receives becomes one message.
- **Listener** -- an export with `adaptorType: "TopicExport"` and `type: "stream"`, the page generator of a flow that runs when messages arrive.

Concerns when working with topics:

- **The topic** -- name, retention, the license that gates it, and registration on the integrations whose flows use it
- **Publishing** -- a publisher step in a flow, API, or Tool, or a direct publish call
- **Listening** -- a listener step, and the flow-enable transition that subscribes it
- **Messages** -- reading what is retained (never moves a listener) and purging it (irreversible)
- **Positions** -- each listener's offset on the topic: where its next run resumes

## How to Run the Steps

This skill names each step by what it reads or changes; the exact calls depend on how you reach the account. Read the one reference that matches your tools -- both follow the step numbers of How to Build an Event Stream below, then the headings of Messages and Positions, Diagnosing a Listener That Never Runs, and Delete, Restore, and Copies:
