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 🙏

Dev Workflow Skill

A structured 6-phase development sprint: Think → Plan → Build → Review → Test → Ship. Role-based subagents at each phase. Inspired by Garry Tan's gstack.

Works with any Agent Skills compatible tool: Claude Code, OpenAI Codex, Trae, Cursor, Gemini CLI, and more.

What This Is

gstack is Garry Tan's (CEO of Y Combinator) open-source software factory for Claude Code — 15 specialist roles and 6 power tools that turn Claude Code into a virtual engineering team.

This skill takes gstack's core insight — structured roles beat generic prompting — and packages it as a portable Agent Skill that works across 20+ AI coding tools, not just Claude Code.

What we kept from gstack:

  • The Think → Plan → Build → Review → Test → Ship workflow
  • Role-based subagent spawning (YC Coach, Eng Manager, Staff Engineer, QA Lead, Release Engineer)
  • Design doc as the central artifact that flows between phases
  • Paranoid review culture

What we changed:

  • Simplified from 15 skills to 6 phases (most people don't need all 15)
  • Made it tool-agnostic via Agent Skills standard
  • Focused on solo dev / small team use case
  • Added model selection guidance per phase

Phases

| # | Phase | Role | Spawns | Output | |---|-------|------|--------|--------| | 1 | Think | YC Office Hours Coach | Sonnet | DESIGN.md | | 2 | Plan | Eng Manager | Sonnet | PLAN.md | | 3 | Build | Implementer | Haiku/Sonnet | Code + Tests | | 4 | Review | Staff Engineer | Sonnet | Review Report | | 5 | Test | QA Lead | Sonnet | Bug Report + Fixes | | 6 | Ship | Release Engineer | Haiku | PR / Deploy |

Install

Via npm

npm install -g @jahonn/agentskills-cli
agentskills install ./dev-workflow-skill -t all

Via ClawHub (OpenClaw)

clawhub install gstack-workflow

Manual

Copy the skill directory to your tool's skill folder:

# Claude Code
cp -r dev-workflow-skill ~/.claude/skills/dev-workflow

# Codex
cp -r dev-workflow-skill ~/.codex/skills/dev-workflow

Usage

Full sprint

"Build me a [feature]" → runs all 6 phases
"Run dev-workflow on [description]"

Partial sprint

"Just review and ship this branch" → Review → Ship
"I have DESIGN.md, skip to Plan"

Single phase

"/think [idea]"
"/review"
"/ship"

How It Works

Each phase spawns a focused subagent with a specialized prompt. The subagent works in isolation, produces a structured artifact, and passes it to the next phase.

User idea → DESIGN.md → PLAN.md → Code → Review → Tests → PR
           (Think)     (Plan)    (Build) (Review) (Test)  (Ship)

Key principle: no code until the plan is approved. Challenge scope ruthlessly.

Frameworks Used

  • YC Office Hours — reframing problems before solving them
  • Amazon Working Backwards — press release before PRD
  • INVEST — user story quality criteria
  • RICE — feature prioritization
