# GitHub

> Turn issues into PRs, iterate on review feedback, and let Twill fix CI — all from GitHub.

GitHub is connected during [onboarding](/quickstart) by installing the Twill GitHub App on the repositories you choose. That installation powers everything here.

## Start tasks from issues

Mention `@twill` in an issue body or comment, or add the `twill` label. Twill reacts with 👀, works the issue in your [dev environment](/environment), and links the resulting PR back.

Plans and clarifying questions post back as issue comments, and your replies continue the task. To force plan-first or pick a model, include a `/trigger` in the text or add a label matching one of your [routing configs](/agent-config/routing) — for example `/plan`.

## Work on any pull request

Mention `@twill` in a PR conversation or a code-review thread — on any PR, not just Twill's own. Twill checks out the PR branch and pushes to it.

For review feedback: leave `@twill` comments in **unresolved** review threads. Twill waits about 2 minutes to batch multiple comments, then addresses all unresolved threads in one pass.

## Automatic completion & CI fixes

* When a PR linked to a task is merged, the task moves to **Completed** on its own.
* When CI fails on a Twill PR, Twill reads the logs and pushes a fix — up to 3 attempts per failure. See [Verification](/verification#ci-auto-fix).
