Write rules without leaving your editor

The rule you need to change is usually obvious while you are building. Change it there.
Ask where you already are
Spot something to fix mid-build and tell your agent, without changing window.
It lands everywhere
The rule updates for every AI tool you have connected, with no file to keep in sync.

Never rely on color alone to signal that a Button is interactive.

Set up in minutes, then forget about it

One connection
Connect over MCP or the CLI and you’re done.
Nothing in your codebase
No package to install, no config to commit, no build step to add.
Nothing to maintain
No versions to bump and nothing that breaks the next time you ship.

The same rules, every time

Change it once

Update a rule or a value in a single place.

Every AI tool follows

Each connected tool picks the change up automatically, on its next build.

No files to juggle

No markdown or skill files to copy between tools and maintain by hand.

Nothing drifts

No stale copies quietly going out of date behind your back.
