Build Your Own
Step 1
Find the API
Open DevTools → Network, interact with the site, and find the REST endpoints it calls.
Step 2
Write Python scripts
One script per action. Use argparse for input, print JSON to stdout. sig run injects credentials.
Step 3
Write SKILL.md
Document each script's purpose, args, and examples. The AI agent reads this to operate your skill.
