How it works

What the collaboration looks like when we work with maintainers and core contributors.

01

Use Charlie for real changes

We draft and iterate on PRs you were going to do anyway.

02

You stay the reviewers

You keep control: review, request edits, and merge.

03

Momentum shows up quickly

Expect more shipped work and fewer maintainer bottlenecks.

04

Bi-Weekly Check-ins

A quick sync to adjust scope and capture feedback.

How do we know this will work?

Because Charlie built all of Charlie (~90% of PRs) with <5 contributors in weeks not years.
