Verifies sibling file access and progressive disclosure capabilities within the Copilot CLI environment.
This test-only skill serves as a specialized smoke test fixture designed to validate the infrastructure of the Copilot CLI. Its primary purpose is to ensure that the AI can correctly resolve, read, and process sibling files referenced within a skill's directory structure. By attempting to access a specific 'reference.md' file, it provides a reliable method for developers to test progressive disclosure mechanics and environment configuration without the overhead of production logic.
