TanabeSugano

Guides agents using the TanabeSugano MCP server to compute eigenvalues, Tanabe-Sugano diagrams, and term-symbol energies for d2-d8 transition-metal complexes. Use when the user asks about ligand-field splitting, octahedral d-d transitions, Racah parameters (B, C), or absorption spectra interpretation. DO NOT USE for unrelated quantum chemistry or for crystal structure analysis.

Routes open-ended "what is a Tanabe-Sugano diagram?" or "I want to explore d^n ions" conversations to the TanabeSugano MCP server's discovery entry points (`ts_dashboard_app` overview, `tanabesugano_why` prompt). Use when the user has no specific parameters yet -- before they know to ask about Dq, Racah B/C, or specific term symbols.

Helps agents choose between matplotlib PNG output (cheap, default) and the interactive Prefab LinePlot view when visualizing Tanabe-Sugano diagrams via the TanabeSugano MCP server. Use when the user asks for a plot, graph, or visualization of d-d transitions.
