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 🙏

prompt-budget-advisor-skill

Portable Agent Skill for estimating visible prompt token budget and rewriting prompts so they are shorter, clearer, and easier for coding agents or chat agents to execute.

The package installs a standards-style prompt-budget-advisor skill for Codex and Claude Code.

Install

Install to both personal Codex and Claude skill directories:

npx prompt-budget-advisor-skill install

Install to one agent:

npx prompt-budget-advisor-skill install --target codex
npx prompt-budget-advisor-skill install --target claude

Install into a project:

npx prompt-budget-advisor-skill install --scope project --target both

Install into the open .agents/skills location:

npx prompt-budget-advisor-skill install --target agents

Usage

Ask your agent to use prompt-budget-advisor, or invoke /prompt-budget-advisor in agents that support slash skill invocation.

Example prompt:

Use prompt-budget-advisor to estimate this prompt's context cost and rewrite it:
<paste prompt here>

The skill reports an approximate visible-token estimate, prompt-budget issues, a clearer rewrite, and a shorter variant.

CLI

prompt-budget-advisor-skill help
prompt-budget-advisor-skill validate
prompt-budget-advisor-skill path

Default user locations:

  • Codex: $CODEX_HOME/skills or ~/.codex/skills
  • Claude: $CLAUDE_HOME/skills or ~/.claude/skills
  • Agents: $AGENTS_HOME/skills or ~/.agents/skills

Notes

Token counts are estimates. The real context consumed by an agent also includes hidden system/developer messages, prior conversation, tool output, files read into context, and model-specific tokenization overhead.
