Create Rules for agents

Create reusable Rules in Warp to encode team conventions — like Dockerfile patterns or dependency management — so agents follow your standards.

Speaker: Maggie — Engineer at Warp

1. Starting with Agent Mode evals

I’m currently adding Evals (short for evaluations) to test a new feature I’ve been building.

Warp quickly surfaces helpful context — like notebooks and internal docs — written by teammates on how to run Evals.

This makes onboarding onto new tasks fast and collaborative.

2. Adding a Rust syntax eval

Next, I want to add an Eval that tests for Rust syntax errors.
So I ask Warp to update the Dockerfile to include Rust.

However, the generated Dockerfile installs Rust differently than I wanted.
It also includes gcc and python via a single apt-get line, which doesn’t follow our internal conventions.

3. Stashing changes and creating a Rule

Instead of fixing this manually every time, I decide to stash the current changes and create a reusable Rule that encodes our convention:

Rule Example:
“Always use apt-get to install packages and follow the same pattern used for installing Python and GCC.”

This way, future sessions — and even other teammates — can automatically apply the same standard.

4. Applying the Rule

Now, I just ask Warp’s Agent Mode to try again!

Warp re-runs the request, follows the new rule, and correctly adds Rust with the right syntax. The code now matches our conventions.
