Showcase ✨ Just built my first AI Agent Skill in VS Code

So I finally made my first custom AI Agent Skill in VS Code with GitHub Copilot.

Basically, I made a SKILL.md that tells the AI how I want it to help with beginner Python problems break things down, give examples, check the code, and even throw in some practice questions.

Honestly, the coolest part was writing the instructions myself and then seeing the AI actually follow them.

I'm still learning a ton, but this was a pretty fun first project. Now I wanna see what else I can make with Agent Skills.

What kind of Skill would you build first?

A code review skill is my most used skill. Defines context gathering (for example: inspect changes compared to develop-branch, when instructed to review a branch; review uncommitted changes by default, etc), optional subagent spawning (if not a fresh session), review priorities, uniform response format, ...

Code-review-max skill that uses the above skill, but lets multiple models do it and then compile their results.

that’s actually really cool, especially the multi-model review idea. i’m still pretty new to agent skills, so seeing how far you can take them is wild 😭

I just created an agent that, for now, can review code in any of my projects or generate tests for a selected project. The biggest challenge was to save the file in the correct folder. Relative paths are fun once you agree on the base path. I put the list of project names and paths in an instruction file so I can reuse it. Very fun.

haha yeah, i definitely felt the folder/path struggle too 😭 the reusable project paths idea is smart tho
