For Day 3, I built a skill called scaffold-module. It scaffolds a new Python module by reading an existing module in the repo and mirroring its structure: same layers, naming, and framework style (FastAPI, Django, etc.). Triggered with /scaffold-module payments "handles Stripe webhooks and refunds".
One optimization I made was adding a hard overwrite guardrail after watching it work. If the target folder or any file already exists, it stops and reports instead of merging or overwriting. I also made it show the planned file list for confirmation before writing anything, so nothing gets generated silently.
I attached a screenshot of the skill file.
