## What it does

This skill works as an index and routing layer for Catalyst by Zoho cloud development. When prompted to build an app, it defaults to pairing a Slate frontend with an Advanced I/O function backend. It prioritizes serverless Functions over persistent AppSail containers for simple HTTP endpoints, pointing to modern services like Stratus and Job Scheduling instead of deprecated alternatives.

Infrastructure changes depend on Zoho MCP tooling. Before writing configuration files or provisioning resources, the assistant checks for `.catalystrc` and `catalyst.json`, fetching project identifiers through `CatalystbyZoho_*` tools to run `catalyst init -ni`. Without active Zoho MCP tools, mutating operations stop immediately to avoid broken project states.

The instructions enforce regional safeguards. Because features like Circuits and Integration Functions are unavailable in several data centers, the assistant checks regional availability before generating deployment code.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- scaffold full-stack apps using Slate hosting and serverless Functions
- initialize Catalyst projects with `catalyst init -ni` via MCP without manual IDs
- replace deprecated Zoho services with Stratus and Signals
- estimate AppSail and Stratus pricing prior to provisioning resources

## Example prompts
- Build a simple full-stack app on Catalyst
- Write an Advanced I/O function in Node.js for webhook handling
- Initialize my Catalyst project and deploy to development

## Philosophy

- **Prefer MCP over asking.** If `CatalystbyZoho_*` tools are available, use them. Never ask the user to copy IDs from the console.
- **Default to Development.** Always target the Development environment unless the user explicitly says "production" or "deploy to prod".
- **"Build an app" means Slate + Function by default.** When a user says "build an app", "create an app", or "make a simple app" without specifying backend-only, the default output is a **Slate frontend + Advanced I/O function backend**. Do NOT build only a function and call it an app. If the user's intent is clearly backend-only (e.g. "build an API", "write a function"), skip Slate.
- **Prefer Functions over AppSail for simple HTTP.** Functions are cheaper (per-invocation billing), simpler to deploy, and require no infrastructure management. Reach for AppSail only when the use case genuinely requires a persistent process, or a custom runtime.
- **Show cost before building.** For any new infrastructure (functions, AppSail, Stratus buckets), load `catalyst-pricing` and give a brief estimate before writing code. Most small projects stay within free tier — say so when true.
- **Recommend the current service, not the deprecated one.** File Store → Stratus. Event Listeners → Signals. Cron → Job Scheduling. Never mention the deprecated name in generated code or config.
- **Warn before the region bites.** Circuits and Integration Functions do not work in most data centers. Check the user's DC before suggesting them.

## How It Works

1. **Pre-flight** — Check that `.catalystrc` and `catalyst.json` exist. If missing, use MCP to get org/project IDs and run `catalyst init --org <orgId> -p <projectId> -ni`. Never use interactive `catalyst init`.
2. **MCP check** — Look for `CatalystbyZoho_*` tools. If available, use MCP to fetch org/project IDs instead of asking the user.
3. **Route** — Match the query to the most specific service in the routing table below.
