Built a daily story oracle using Claude — the prompt is the whole trick Wanted to share something I finished this week that started as a prompt experiment and turned into a full app. What it does: You enter birth date, time, and place. Vanilla JS calculates planetary transits, aspects to your natal chart, Sabian Symbols for the transiting Sun and Moon, lunar phase, Whole Sign house placements via Nominatim geocoding, and personal day numerology. All of it gets fed silently to Claude, which writes a short story — first person, any era, any character, any place. The prompt philosophy is the whole thing. The astrological data is invisible infrastructure. Claude never names it. The instructions say: the bones don’t show — they just determine how the character moves. Opening image feels like waking into the day. Closing image is a threshold crossed. There’s also an optional “what’s on my mind today” field — seasoning, not subject. The result is genuinely different every day, and genuinely personal in a way that surprised me. Stack: WordPress + PHP proxy + Anthropic API (claude-sonnet-4-20250514) + Meeus ephemeris in vanilla JS.
