Energy Planner

While working through the Autistic Burnout WorkbookI found the idea of applying spoon theory to different types of energy - such as physical, social and executive functioning - to be really helpful. I thought surely a tool must exist to help me put it into practice, but I couldn't find anything that quite fit the bill. So I built my own!

This was also my first substantial build leaning heavily into AI agents, and I used it as a deliberate experiment: where is the right balance between directing the agent with precision versus letting it run? I found that having a library of well-crafted, reusable skills was enormously helpful — the agent produced far better output when given clear, specific patterns to follow.

Tests were, of course, essential - "vibe coding" new features quickly breaks old ones without a solid test suite! I found mutation testing (via Stryker) is a great way to validate test quality without having to manually review every line. It surfaced gaps I wouldn't have noticed, and gave me real confidence in the test suite — a great intro to “harness engineering”.

I tried out two major AI coding tools on the project: Antigravity had promising browser interaction but too many teething issues on WSL, while Claude Code was a genuine joy to work with. Having spent years reviewing other people's code professionally, I found that experience transferred directly — I just had to remind myself it's fine to jump in and fix things directly, since I'm not robbing anyone of a learning opportunity but myself!
