catalyst-pricing — Claude Code skill: what it does, how to install

Q: How to install catalyst-pricing in Claude Code?

Run `npx skills add catalystbyzoho/agent-skills --skill catalyst-pricing -a claude-code` in your terminal.

Q: How does the skill estimate function execution costs?

It applies the formula `(memory in GB) × (execution time in seconds) × (invocation count)` and gives a range rather than a single number to reflect real traffic.

Calculates Catalyst pricing, inspects free tier limits, and estimates function execution costs using GB-seconds.

What catalyst-pricing 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.

What it helps with

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 for the agent

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

What does the catalyst-pricing skill do?

It checks Catalyst service pricing, calculates GB-seconds for function runs, and compares free tier allowances against pay-as-you-go rates.

How does the skill estimate function execution costs?

It applies the formula (memory in GB) × (execution time in seconds) × (invocation count) and gives a range rather than a single number to reflect real traffic.

## 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".
