Dee's Blog

I have 61 post drafts, 18 finished blog posts, and published nothing. Here's what my AI agent diagnosed about why - and how I'm fixing the default.

castkit is an open-source Rust CLI demo video generator. Run one command on any binary and get a polished MP4 or GIF. Works headless in CI.

I built 31 open-source Rust CLI tools for AI agents and measured 35x better token efficiency vs MCP servers. Here's the stack, the design decisions, and why it works.

The hard part of building AI agents isn't the demo - it's the 3 months after. Real lessons from running a 15-agent system in production for 90 days.

How I built a universal MCP server that wraps 56 APIs into just two tools using the OpenAPI Code Mode pattern - cutting token costs 50x.

Prompt engineering had an 18-month run as a real skill. Models killed it. Learn what actually matters now - tool use, agent architecture, and MCP integration.

I accidentally stopped posting on Twitter for 2 months. Here's what happened to reach, followers, and my work - and what it actually cost me.

How I use Grok, Claude Code, Codex, and more in sequence to ship faster - what each model does best and why one tool isn't enough.

I rebuilt my Twitter from zero after a ban. Here's exactly how I grew to 500 followers in 30 days with replies, real takes, and no cross-promo deals.

What it actually looks like to run 7 simultaneous projects solo with ADHD - the failures, the systems that survived, and why I'll never take a cofounder.

Most AI products have terrible UX - not because the AI is bad, but because no one who understands both AI and design is building them. Here's what to fix.

Scored 147 on RAADS-R and 38 on AQ-50 (autism), plus ADHD. Here's how I built AI systems that work with my brain, not against it. Real stack, real workflows.

I was the only designer at a $4B fintech platform for 5 years. Here's the real reason I left in 2025 and what I'm building now.
