STOP Building AI Agents. Do THIS Instead.¶
Summary¶
Zubair Trabzada explains Anthropic's "stop building agents, build skills instead" thesis and demonstrates a real-world project: a GEO (Generative Engine Optimization) audit system powered entirely by Claude Skills.
Key Takeaways¶
The Problem with Building Separate Agents¶
Everyone builds a separate agent for every use case: - Tax agent, legal agent, marketing agent — each with its own tools, setup, architecture - Doesn't scale, exhausting to maintain - Intelligence is not the same as expertise
Skills Explained Simply¶
At its core, a skill is a markdown file — a playbook you hand a new employee: - "Here's how we do things. Here are the steps. Here's what to watch out for." - Lives inside a folder that can include scripts, templates, examples - Progressive disclosure — Claude sees only skill titles at startup, pulls full instructions only when needed - Like reading the title on a book spine — only opens the book when needed
MCP vs Skills¶
| MCP | Skills | |
|---|---|---|
| Role | Claude's connections to external tools and data | What Claude does with all of that |
| Analogy | The hands | The experience |
GEO Audit Demo¶
A real project using 12 Skills to analyze any website for AI search visibility:
- /geo-audit slash command triggers the full analysis
- Skills instruct Claude to run 5 sub-agents simultaneously (parallel delegation)
- Produces executive summary, score breakdown across ChatGPT, Perplexity, Gemini, Bing
- Generates prioritized action plan for improving AI visibility
- Skills can be simple (no sub-agents) or complex (multi-agent orchestration)
Plain English Invocation¶
You don't need to run specific slash commands. Claude is smart enough to: - Look into the skills files - Determine which skill is relevant for the user's request - Pull the right instructions off the shelf - Execute the task
Non-Technical Users Can Create Skills¶
- Recruiter — teach Claude your hiring process, evaluation criteria, interview question bank
- Finance — teach Claude how to build reports the way your team does them
- Legal — teach Claude how to review contracts the way your firm does it
