For vibe coders

Your AI writes the code.
act101 keeps it from making a mess.

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.

In plain English

What this actually does for you.

Better results.

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.

Stays focused.

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.

Costs less.

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.

Is this for me?

If any of this sounds like you…

Then this is for you. Setup is one line, and you never have to touch it again.

Setup

Paste one line. That's the whole thing.

Run this in your terminal. Your coding agent picks it up automatically — there's nothing to configure and nothing new to learn.

macOS / Linux
curl -sSL https://raw.githubusercontent.com/act101-ai/act101/main/install.sh | sh
Windows (PowerShell)
irm https://raw.githubusercontent.com/act101-ai/act101/main/install.ps1 | iex

Not ready to install?

Get a free health report on a repo — nothing to set up.

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.
