# chemistry-gaussian-overlap

`station__chemistry__chemistry-gaussian-overlap` · external (needs EXECUTION_BACKEND_URL configured) · domain `chemistry` · pv-relevance `pv-adjacent`

PV confidence: 0.78 (wavefunction overlap → signal co-occurrence)

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.

## Agent metadata

- `idempotent`: unknown

- `cost_tokens_estimate`: unknown

## Input schema

- `center_a` *object* (required) — Position of center A as [x, y, z]
- `center_b` *object* (required) — Position of center B as [x, y, z]
- `coefficients_a` *array* (required) — Contraction coefficients for center A
- `coefficients_b` *array* (required) — Contraction coefficients for center B
- `exponents_a` *array* (required) — Exponents of Gaussian primitives on center A
