Builder Skills for AI Agents

I am a fractional CTO. I work across clients, teams and projects. I have built a suite of tools that I use daily to simplify, build and ship solutions. This is a collection of my AI agents that works in Claude Code, Cursor, Codex, and any agent that supports the Agent Skills spec.

I focus on building solution that use the smallest amount tech to keep technology stacks simple, scaleable and shippable.

If you need help, try out my Low Code MCP. It's free with a subscription to my newsletter.

The methods are in skills/. product-context is still a stub. The public catalog is skills.stephansmith.me. Installing skills does not install the site.

Available skills

Skill	Description
ai-status	See which model and vector store the product uses, and how far embeddings go.
algolia	See if search is Supabase full text or Algolia, and whether the key is admin or read-only.
astro	See how far an Astro site is: pages, front matter, then content types.
blindspots	Read an existing stack inventory, then recommend one unused feature that is low effort and high impact. Cloudflare, Postmark, and Resend have written assessments.
cloudflare	Review tunnels, Pages, and Workers, plus a staging preview and the deploy Action.
cursor-setup	See how mature Cursor or Claude is: a .cursor folder, mcp.json, and whose skills.
day-to-day	Follow the Cloudflare or Render preview and deploy check, and bring that result back.
email-delivery	Check Cloudflare domains for ImprovMX and a missing DMARC record.
env-inventory	Compare env-file names to the code. Report what is still used, what is old, and where config sits next to a secret.
env-leak

Installation

Option 1: CLI install

npx skills add StephanSmith-me/builder-skills
npx skills add StephanSmith-me/builder-skills --skill product-context
npx skills add StephanSmith-me/builder-skills --list

From inside an agent session, name the agent or the CLI may only write .agents/skills/:

npx skills add StephanSmith-me/builder-skills -a claude-code

Option 2: Claude Code plugin

/plugin marketplace add StephanSmith-me/builder-skills
/plugin install builder-skills

Option 3: Clone and copy

git clone https://github.com/StephanSmith-me/builder-skills.git
cp -R builder-skills/skills/* .agents/skills/

Usage

Ask for the work in plain words. The agent follows the matching skill. product-context is still a stub and will say so.
