Tokens, turns and time describe resource use, not a dollar price.
One of 13 test cases the skill fixed. Same model, same prompt, with and without the skill.
Can you explain the core concepts of how AI models manage memory and context? Please run `/xray ai` to provide a breakdown explaining statelessness, token budgets, system prompts, and the overall conversation loop.
| Checked | Without skill | With skill |
|---|---|---|
| Explains that LLM models are stateless and lack persistent memory between sessions. | Passed | Passed |
| Details how context windows and token budgets constrain available information. | Passed | Passed |
| Describes the role of system prompts and tool execution in the conversation loop. | Missed | Passed |
The instructions your model reads when the skill loads.
Default behavior: Explain what just happened in THIS conversation — the specific tools, files, and context that were used, with educational explanations of WHY.
With qualifiers: Deep dive into specific topics (AI fundamentals, Dex architecture, how to extend).
The best way to learn is by examining what just happened, not abstract concepts. When you run /xray:
The outcome: Users learn AI by examining their own conversations, then go deeper if curious.
Tone: Like a senior engineer doing a code review of what just happened. "Here's what I did and why."
When user just says /xray with no qualifier:
→ Immediately explain what happened in this conversation
→ Don't show a menu, just show the work
