You don't have to learn act101 — your coding agent already knows how to use it. It just makes your agent give you better results: fewer broken changes, less confusion, and a smaller bill at the end of the month.
Your agent stops guessing. Instead of skimming your files and hoping, it gets exact answers about your code — so it makes fewer dumb mistakes and breaks fewer things that were already working.
When an agent reads piles of code it doesn't need, it gets confused and loses the plot halfway through. act101 hands it just the part that matters, so it stays on track.
All that skimming burns tokens — real money on your Cursor or Claude bill. Feeding your agent less junk cuts that down. A nice side effect, not the point.
Then this is for you. Setup is one line, and you never have to touch it again.
Run this in your terminal. Your coding agent picks it up automatically — there's nothing to configure and nothing new to learn.

Point act101 online at a GitHub repo and it grades what your agent has been writing: one score, security and structure. It runs on GitHub, so there's nothing to install and nothing on your machine. Free for public repos.
The free edition already makes your agent smarter. The paid tiers add a safety net that checks your agent's changes before they land.
Want the full breakdown and every tier? See all plans. Every paid tier comes with a 7-day free trial.
One line in your terminal and your agent starts using it. Free to start, nothing to configure.
