About The Harness

The Harness is a technical blog for people who build with AI — agent systems, Claude Code workflows, MCP servers, and the parts of the stack that don’t have documentation yet. The writing is rigorous, practical, and tied to things that actually ship.

Each article is a durable reference. A short-form video may have brought you here; this page is why the video exists.

What you’ll find here

• Pillars on agent architecture, tool design, and eval loops
• Teardowns of real workflows (Claude Code hooks, skills, subagents)
• Model-comparison notes grounded in concrete tasks
• Honest accounts of what works and what doesn’t

What you won’t find

• Hype takes, AGI speculation, or Anthropic-roadmap guessing
• “Top 10 prompts” slop
• Affiliate funnels or course sales
