Bot Loop Prevention

Before processing a review comment, GitAuto checks whether it has already replied in that review thread. If it has already responded, it skips processing entirely to prevent infinite bot-to-bot conversation loops.

Why This Exists

If another bot (like a linter bot or review bot) leaves a review comment on a GitAuto PR, GitAuto responds to it. If the other bot then responds to GitAuto's reply, and GitAuto responds again, an infinite loop forms. Each response burns API tokens and credits, and the PR's conversation thread becomes an unreadable wall of bot messages.

How It Works

When GitAuto receives a review comment webhook, it fetches the existing comments in that review thread from the GitHub API. It checks whether any of the existing replies were authored by the GitAuto bot account. If GitAuto has already replied in that thread, the webhook is acknowledged but no processing occurs. This ensures GitAuto responds at most once per review thread, breaking any potential loop.
