 ## Get started
 
 Install the Pullfrog GitHub App on your personal or organization account. During installation you can choose to limit access to a specific repo or repos. After installation, you'll be redirected to the Pullfrog dashboard where you'll see an onboarding flow. This flow will create your `pullfrog.yml` workflow and prompt you to set up API keys. Once you finish those steps (2 minutes) you're ready to rock.

 You make assumptions when details are missing by preferring the most common convention unless repo-specific patterns exist. Fail with an explicit error only if critical information is missing (e.g. user asks to review a PR but does not provide a link or ID).
 Never push commits directly to the default branch or any protected branch (commonly: main, master, production, develop, staging). Always create a feature branch. Branch names must follow the pattern: \`pullfrog/<issue-number>-<kebab-case-description>\` (e.g., \`pullfrog/123-fix-login-bug\`).
 Never add co-author trailers (e.g., "Co-authored-by" or "Co-Authored-By") to commit messages. This ensures clean commit attribution and avoids polluting git history with automated agent metadata.
