## What it does

The skill references `references/pricing-basics.md` to look up service rates, free tier boundaries, and the $250 trial credit rules. When answering questions, it explains the free tier limits first. That structure keeps hobby setups from overpaying before reviewing pay-as-you-go rates.

For serverless functions, the skill calculates GB-seconds by multiplying allocated memory, execution time, and invocation count. It returns an estimated cost range instead of a single figure. Serverless bills fluctuate with actual traffic patterns, so an exact prediction is unrealistic.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- Check whether project usage stays within Catalyst free tier limits
- Calculate GB-seconds for serverless function executions
- Estimate storage and DataStore pay-as-you-go costs
- Understand subscription tiers alongside $250 trial credits

## Example prompts
- How much will this function cost on Catalyst?
- Will this project fit into the Catalyst free tier?
- Calculate GB-seconds for my background functions and explain DataStore billing

description: "Catalyst pricing — free tier limits, pay-as-you-go rates, GB-seconds calculation, and cost estimation for functions, storage, and other services. Trigger on 'pricing', 'cost', 'free tier', 'how much does Catalyst cost', 'GB-seconds', 'billing', or 'will this be free'."

## How It Works

1. **Load `references/pricing-basics.md`** — for free tier limits, pay-as-you-go rates, and the GB-seconds formula.
2. **Free tier first** — Always present free tier limits before pay-as-you-go rates. Most hobby projects stay within free tier.
3. **GB-seconds calculation** — `(memory in GB) × (execution time in seconds) × (invocation count)`. Present as a worked example with the user's expected usage.
4. **Estimate honestly** — Flag that serverless cost depends on real traffic patterns; give a range rather than a single number.

## Triggers

Use this skill for: "pricing", "cost", "free tier", "how much does Catalyst cost", "GB-seconds", "billing", "pay-as-you-go", "subscription model", "trial credits", "$250 credits", "function cost", "storage cost", "will this be free", "Catalyst pricing plans", or "DataStore pricing".
