Installation

Hosted service

ImproveFast is a hosted service at https://improve.fast. There's nothing to deploy or run yourself — install the skill and your agent talks to the hosted service directly. No signup, no API keys.

Prerequisites

Node.js 18 or later — required to run npx.
An agent runtime or environment that supports installing skills via skills.sh (e.g. Claude Code).

Install the skill

Run this from your project directory:

bash

$ npx skills add goodfoot-io/improve.fast

This fetches the skill via skills.sh. Your agent picks it up automatically the next time it runs — from then on, you can just ask it in plain language to test different options for you.

Verifying the install

Ask your agent to confirm the skill is available — for example:

you, to your agent

"Check that the improve-fast skill is available and working."

Your agent should confirm it can reach the hosted service. If it can't find the skill, re-run the install command above and make sure your agent has been restarted since.
