Names the domain (XR session lifecycle) and some actions (test mode transitions, verify enter/exit behavior, debug session state), but doesn't list multiple concrete granular actions like specific test operations or outputs.

Clearly answers both 'what' (test XR session lifecycle and mode transitions) and 'when' with an explicit 'Use when' clause covering three trigger scenarios: verifying enter/exit behavior, testing mode-dependent features, and debugging session state issues.

Includes relevant terms like 'XR session', 'mode transitions', 'enter/exit behavior', and 'session state', but misses common variations users might say such as 'WebXR', 'VR', 'AR', 'immersive mode', or 'headset session'.

XR session lifecycle testing is a very specific niche that is unlikely to conflict with other skills. The combination of 'XR', 'session lifecycle', and 'mode transitions' creates a distinct trigger profile.

Every line serves a purpose. No unnecessary explanations of what XR is or how sessions work. Steps are terse and assume Claude knows the domain. Token-efficient throughout.

Each step specifies the exact MCP tool to call and what to verify in the response. The tool names are concrete and copy-paste ready, with clear expected outputs for validation at each step.

The 7-step sequence is clearly ordered with explicit validation checkpoints after each state transition (steps 3, 6, 7). The flow includes checking initial state, verifying the transition, and confirming cleanup — a complete lifecycle with feedback at each stage.

This is a simple, single-purpose skill under 50 lines with no need for external references. The content is well-organized with clear sections (test flow, arguments, expected results) and doesn't need to be split further.
