What problem does it solve? Google Cloud API calls in KHI fail with authentication, quota, or routing errors when required call options (gRPC metadata, routing headers, credentials) are not propagated to the request context. This Skill provides the mandatory patterns for injecting those options correctly. ## Core Features & Use Cases - Task Integration Pattern: Shows how to retrieve CallOptionInjector through the KHI task DAG dependency system using APIClientCallOptionsInjectorTaskID. - Reusable Component Pattern: Defines how fetchers and helper structs accept, store, and apply CallOptionInjector before RPC calls and errgroup goroutines. - Raw HTTP Support: Covers ApplyToRawHTTPHeader for REST requests where gRPC context options do not apply, plus unit testing with mock CallOptionInjectorOption. - Use Case: When writing a new KHI inspection task that queries Cloud Logging, follow this guide to inject call options into the context before creating the logging client, preventing quota and routing failures. ## Quick Start Show me how to call the Cloud Logging API from a new KHI inspection task with proper call option injection.
