When to Use This Skill

Use this skill whenever a code change introduces a new environment variable (or renames/aliases an existing one). In dd-trace-py every DD_*, _DD_*, OTEL_*, or DATADOG_* variable accessed under ddtrace/ MUST be registered, or the supported_configurations CI check fails.

Typical trigger: you just added something like DDConfig.var(bool, AI_GUARD.ENV_OPENAI_ENABLED, default=True) in a settings module and need to make CI / docs happy.
