Token预算顾问（TBA）

name: Token Budget Advisor (token-budget-advisor) description: Before answering, present users with informed choices about how much of the model's response budget (depth/length) to consume. Use this skill when the user explicitly wants to control response length, depth, or token budget. Trigger conditions: "token budget", "token count", "token usage", "token limit", "response length", "answer depth", etc. Behavior: estimate input tokens heuristically (prose: words × 1.3; code: chars ÷ 4), apply a multiplier range by prompt complexity (simple / medium / medium-high / complex / creative) to calculate the available response window, and present four depth options (25% / 50% / 75% / 100%) with approximate token counts and expected output characteristics. Use cases: save API costs, request shorter or more detailed answers, control code snippet output, avoid truncation or overly long replies. Will not trigger when a session-level setting already defines depth or when the request clearly expects a one-word answer. Benefits: improved cost predictability, greater user control, and better response quality (heuristic accuracy ~85–90%).
