## What it does

Catalyst Signals is an event-driven platform that lets decoupled applications talk to each other almost instantly. The skill walks through the flow: a publisher emits an event, a rule with filters and transforms routes it to a target — a webhook, function or circuit. Everything is configured in the Catalyst console, and there is no programmatic interface for creating publishers or rules.

Inside sits `references/signals-basics.md`: publisher types (Zoho, Catalyst CloudScale, Custom), event schemas, the custom event REST API, targets, dispatch policies, retries and statuses. A security checklist covers the 500 requests-per-minute limit on the custom publisher REST API, separate URLs for Development and Production, and payload caps of 100KB for Zoho and 64KB for Custom events.

Activate Signals once per project before anything else: Console → your project → Signals → Start Exploring. Skip that and Publishers, Webhooks, Rules and Logs stay out of reach. One more thing to plan around: rules are locked in production, so all changes happen in Development and get deployed. A deployment holds at most 25 publishers.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-signals -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-signals -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-signals -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install catalystbyzoho/agent-skills catalyst-signals
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-signals -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/catalystbyzoho/agent-skills --path skills/catalyst-signals
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add catalystbyzoho/agent-skills --skill catalyst-signals -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/catalystbyzoho/agent-skills/tree/HEAD/skills/catalyst-signals/SKILL.md

## When to use it
- connect two apps through an event bus without direct calls
- filter and transform a payload before it reaches the target
- pick between instant and batch dispatch for an event
- attach a webhook or function as a rule target
- trace a missing event through logs and statuses

## Example prompts
- Help me set up a Catalyst Signals publisher for a new event
- Explain how a rule with a filter sends an event to a webhook
- Which dispatch policy fits scheduled batch delivery?

description: "Catalyst Signals — event-driven architecture platform for near-instantaneous communication between decoupled applications. Supports Zoho publishers, Catalyst publishers, custom publishers, webhooks, functions, circuits, event filtering, transformation, batch/scheduled dispatch, and retry policies. Trigger on 'Signals', 'event bus', 'publisher', 'event-driven', 'webhook target', 'dispatch policy', 'event transformation', 'rule filter', or 'event ordering'. Console-only service — no SDK or programmatic API."

## Prerequisites

Before using Signals, activate it once per project in the console:
> Console → your project → **Signals** (left sidebar) → click **"Start Exploring"**

Skipping this step prevents access to Publishers, Webhooks, Rules, and Logs. This is a one-time activation per project.

---

## How It Works

1. **Console-Only Service — HARD STOP if user expects SDK/API.**
   Catalyst Signals is configured entirely through the Catalyst Console — there is NO SDK, REST API, or programmatic interface for creating publishers, rules, or webhooks. All setup is done via the console UI.
   - Publishers, events, webhooks, and rules are created in Console → Signals
   - Functions and Circuits are created separately in Console → Serverless, then selected as targets in Signals rules
   - The only code-level interaction is receiving events in target functions/circuits

2. **Understand the flow** — Publisher → Event → Rule (with filters/transforms) → Target (Webhook/Function/Circuit)
3. **Load `references/signals-basics.md`** — for publishers (Zoho/Catalyst/Custom), events, rules, targets, dispatch policies, event statuses, and deployment gotchas
4. **Key concepts:**
   - **Publishers** emit events when actions occur (3 types: Zoho, Catalyst CloudScale, Custom)
   - **Events** are JSON payloads with auto-generated schemas (max 100KB for Zoho, 64KB for Custom)
   - **Rules** connect publishers to targets with optional filters and payload transformations
   - **Targets** receive events via Webhooks, Functions, or Circuits
   - **Dispatch Policy** controls event delivery: **Instant** (default, immediate) or **Batch** (by count / size / schedule / attribute; TTL fixed at 24h). "One-Time Dispatch" is NOT a policy — it is the no-retry fallback delivery that fires when a Batch's conditions are never met before TTL expiry
```
