Before that, I dropped out of high school, studied computer science at Carnegie Mellon, and wrote engine code for PlayStation games at Naughty Dog.

Now I live in Breckenridge, Colorado — where I snowboard, make music, invest in startups, and build things with AI.

A Depression

An atmospheric, weighty journey from disappointment through damage to whatever's left after. Six tracks. Twenty-eight minutes. The debut EP from Andrew A. Cove.

Two panes side by side. Left, labeled 'before · 3,569 words', a dense wall of skill instructions. Right, labeled 'after · 1,711 words', the same skill cut in half, with an eval report underneath reading 'candidate vs source: every assertion matched — PASS' and a red line showing the deliberately-broken control run failing.

Your agents' skills are too long (mine were too)

Anthropic cut Claude Code's system prompt by 80% because smarter models need less direction. I'd been sensing the same thing about my own skills, so I worked with my agents to cut them down — gating every cut behind an eval instead of vibes.

The Trip Shaper playground: vibe, pace, beach-vs-city, luxury, region, budget, and flights dials down the left; a live 'beach reset' trip card on the right; a 'Send to Claude' dock along the bottom.

Surface makes Claude's playgrounds real

Anthropic's playground skill is one-way: you turn dials, it hands you a prompt to carry to an agent that builds the tool for real. Wire it to surface and the agent is already the backend — the mockup is the live tool, and real results come back into the page.
