list_constellation_presets

Retrieve available rhythmic presets with parameters for temporal oscillation patterns between constellation states, enabling Phase 2.6 rhythmic composition and multi-domain limit cycle discovery.

Instructions

List all available Phase 2.6 rhythmic presets with their parameters.

Layer 1: Pure taxonomy lookup (0 tokens).

Returns preset names, periods, oscillation patterns, state pairs, and descriptions. Presets define temporal oscillation patterns between canonical constellation states for rhythmic composition and Tier 4D multi-domain limit cycle discovery.

Implementation Reference

src/constellation_composition_mcp/server.py:1700-1765 (handler)

The tool handler for 'list_constellation_presets', which lists rhythmic presets by reading from the 'CONSTELLATION_RHYTHMIC_PRESETS' dictionary.
