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 🙏

SFAE — Speak Friend, and Enter

Pronounced "safe."   sfae.io

SFAE lets AI coding agents make authenticated API calls and database queries without ever seeing your credentials. Agents use placeholders such as {ACCESS_TOKEN} or {PASSWORD}. SFAE resolves them from secret storage at execution time, so secrets stay out of chat and out of the context window.

Features

  • Secret-manager storage — macOS Keychain, Windows Credential Manager, Linux Secret Service, or an authenticated SFAE backend.
  • Credentials agents can request safely — API keys, Basic Auth, OAuth 2.0, and more.
  • Communication protocols — HTTP by default, plus Postgres and Redis with --protocol.

Install

Install the SFAE skill in the current project:

curl -fsSL https://sfae.io/install-skill.sh | sh

By default this installs the skill for supported agent targets. To target one agent, pass a flag such as --codex, --claude, or --grok.

curl -fsSL https://sfae.io/install-skill.sh | sh -s -- --codex

The skill includes a small CLI installer. When an agent needs SFAE and the sfae command is not available yet, it can install the CLI through the bundled helper. CLI-only installation and command details live in docs/cli.md.

Quick Start

You normally do not need to run SFAE commands yourself. Install the skill, then ask your agent to use SFAE for authenticated work:

Use SFAE to call the GitHub API and tell me who I am. If credentials are missing, open the SFAE browser form. Do not ask me to paste secrets into chat.
Use SFAE for the API call in this repo. Read the service's official API/auth docs first, collect credentials through SFAE if needed, then make the request with placeholders.

The agent checks which credentials exist, opens a web form when something is missing, and makes the authenticated request with placeholders. You provide secrets only in the browser form, not in chat.

How It Works

  1. The agent reads the service's official API/auth docs and checks for stored credentials.
  2. SFAE offers you a web form for anything missing.
  3. The agent makes HTTP, Postgres, or Redis requests with placeholders, and SFAE resolves them from secret storage.

Roadmap

| Area | Work | | --- | --- | | Authentication | x.509 certificate authentication | | Protocol | Support MySQL / MariaDB | | Protocol | Support MongoDB | | Protocol | Support Microsoft SQL Server / TDS | | Protocol | Support ClickHouse | | Product | Add a credential management UI |
