Repository Setup

Initialize Warden in each repository:

npx @sentry/warden init

This creates:

File	Purpose
warden.toml	Configuration with skills and triggers.
.github/workflows/warden.yml	GitHub Actions workflow.

Secrets

Add the provider credentials used by your configured model. WARDEN_MODEL is a fallback when warden.toml does not set a model; see Models and Runtimes.

Secret	Purpose
WARDEN_MODEL	Fallback model selector.
WARDEN_OPENAI_API_KEY	OpenAI key for OpenAI Pi models.
WARDEN_ANTHROPIC_API_KEY	Anthropic key for Anthropic Pi models or Claude runtime.
WARDEN_SENTRY_DSN	Optional telemetry DSN.

GitHub App

By default, comments come from github-actions. Use a GitHub App for a branded bot identity:

npx @sentry/warden setup-app --org your-org

Add the generated app secrets:

Secret	Purpose
WARDEN_APP_ID	GitHub App ID.
WARDEN_PRIVATE_KEY	Full PEM private key contents.

Then use actions/create-github-app-token and pass the app token to Warden.
