Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (4)

compute_natal_chartCompute a full natal (birth) chart: 10 planets (sign/degree/house/retrograde), 12 Placidus house cusps, and inter-planetary aspects (major aspects, classic orbs). Pass lng/lat/tz_str (e.g. -74.01, 40.71, 'America/New_York') for exact offline computation; otherwise city+nation are geocoded online.
get_current_transitsToday's planetary positions (UTC now at Greenwich) — the current sky, for transit analysis, daily overviews, and timing work.
get_sign_profileReference card for a zodiac sign: element, modality, ruling planet.
validate_interpretationAnti-hallucination confirmation gate (kosma-style): verify interpretation claims are grounded in the chart before publishing them. chart_json = exact JSON from compute_natal_chart or get_current_transits. claims = JSON array: [{"text": "...", "factors": [ {"type": "aspect", "a": "Sun", "b": "Moon"}, # aspect exists in chart {"type": "planet_house", "a": "Sun", "b": 5}, # planet is in that house {"type": "planet_sign", "a": "Sun", "b": "Leo"}, # planet is in that sign {"type": "house_sign", "a": 5, "b": "Leo"}]}] # house cusp is in that sign A claim is supported only if >= 2 of its factors independently exist in the chart. Returns per-claim verdicts; gate = "blocked" if any claim is unsupported — rewrite the claim against verified factors or drop it.

Schemas: list_tools.
