Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Engine CLI — scaffold and validate trading strategy bundles for the Engine marketplace.

Readme

@engine-ai/cli

Scaffold and validate Engine strategy bundles from your terminal.

A strategy is a folder of markdown — a STRATEGY.md constitution plus optional endpoints.yaml, tools.yaml, and references/. This CLI gets that folder started and checks it before you upload it to the Engine app to publish.

Install

npm i -g @engine-ai/cli

Or run without installing:

npx @engine-ai/cli strategy validate

Commands

engine strategy create [name]

Scaffold a new strategy folder. Runs interactively by default:

engine strategy create my-strategy

Or skip the prompts with flags:

engine strategy create my-strategy \
  --name "Crowded Short Fade" \
  --description "Fades crowded shorts on majors when funding is deeply negative." \
  --tags "momentum, crypto" \
  --with-endpoints \
  --yes

| Flag | Description | | --- | --- | | --name <name> | Strategy display name | | --description <text> | One-line description | | --tags <a,b,c> | Comma-separated marketplace tags (max 8) | | --with-endpoints | Include endpoints.yaml (data sources) | | --with-tools | Include tools.yaml (callable tools) | | --yes | Non-interactive; use flags + defaults | | --force | Scaffold into a non-empty directory |

engine strategy validate [path]

Validate a strategy bundle, fully offline. Defaults to the current directory.

cd my-strategy
engine strategy validate

Warnings are fine (exit 0); errors exit 1. Add --json for machine-readable output on stdout (useful in CI):

engine strategy validate --json

Publishing

The CLI gets your folder ready — publishing happens in the Engine app: open the strategy editor, Import folder, enter any required secrets, choose public/private, and publish.

Workflow

engine strategy create my-strategy   # scaffold
cd my-strategy
# edit STRATEGY.md to make it yours
engine strategy validate             # check it's clean
# then upload the folder in the Engine app
