asktian

Get today's personalized Chinese metaphysics (八字 bazi + 干支 daily energy) reading for a person. Returns their archetype (one of 8 trigrams 八卦), today's energy, favorable colors/direction/hours, headline advice, and any caution. Use this when the user asks how today will be for them, what colors to wear, where to face their desk, or for general daily guidance.

Compute fate compatibility between two people via Chinese metaphysics (八字 pairing, 5-element generation/clash). Returns qualitative label first (e.g. '互补型 Complementary'), then a numeric score (hidden if <60 to avoid making low-compat feel like rejection — this is intentional per the asktian design principles). Useful when user asks about compatibility, fit, or 'will this person and I work'.

Find the most auspicious time windows in the next N days for a specific action. Use this when the user asks 'when should I do X', 'should I move this meeting', 'is tomorrow a good day to launch', 'when should I have the hard conversation', etc. Returns top 3 best windows and any windows to avoid. This is the most useful tool for real-time decision support inside any AI assistant — it lets you give specific scheduling advice instead of vague reflections.

Get today's GENERAL energy (no person needed) — the 干支 (stem + branch) and the dominant 5-element character of the day. Useful when the user asks 'what kind of day is it', 'what's the energy today', or when an AI agent wants to add cosmic context to a generic suggestion without needing the user's birthdate.

Quick energetic profile of a name (姓名学 name-analysis). Useful when the user asks about someone's name, a baby name, a company name, or 'what kind of person is X' when no birthdate is available. Returns a one-line vibe + dominant element guess.

Get a Chinese-metaphysics signal on a binary prediction-market question (Polymarket/Kalshi style yes/no outcomes). Use when a user — or a trading agent — wants an UNCORRELATED, for-fun read on a market: 'will X happen by date Y'. Returns a lean (yes/no/neutral), a confidence, the 五行 reasoning from the resolution date's energy, and a mandatory disclaimer. This is ENTERTAINMENT and a falsifiable ritual — NOT financial advice. Always present it as a novelty signal, never as a recommendation to place a bet.
