Build Log: Day 3 — I Thought I Was Building One Skill

🤷‍♂️

Install Skill Builder, make one skill, check the box, move to Day 4.

That's not what happened. Once skill anatomy clicked — a skill is just a folder with a SKILL.md that says what it's for and when to fire — I couldn't stop. I had workflows sitting around that deserved their own trigger: drawing diagrams, generating hand-drawn visuals, building frontend pages, scanning disk space, tracking AZQ status. By the end of the day I'd built nine of them, not one.

**What worked:** the structure itself. Every skill follows the same shape — purpose, trigger, scope — so they're consistent and easy to hand off to next-week me. The disk cleanup and AZQ status tracker skills are already doing real work.

**What broke:** I let a couple of skills auto-trigger before they earned it. One generates images through a paid API, and its trigger conditions were loose enough to fire on the wrong request and spend real money on a guess. I caught it before it ran wild, but had to go back and switch it to "manual invoke only" until it's tested.

**The lesson:** a skill is only as good as its trigger conditions. Loose triggers don't just mean "wrong tool fires" — when the tool costs money per call, a loose trigger is a bill waiting to happen.

**Next:** actually test the experimental skills instead of trusting they'll behave.

Anyone else build more than the assignment asked for once the pattern clicked?
