# Phase Diagram Skills

Tools for thermodynamic and electrochemical phase stability analysis.

## Available Skills

| Skill | Description |
|-------|-------------|
| [convex-hull](convex-hull/SKILL.md) | Thermodynamic convex hull construction, formation energies, energy above hull, decomposition products. Uses MP API and/or MACE-computed energies with pymatgen PhaseDiagram. |
| [pourbaix-diagram](pourbaix-diagram/SKILL.md) | Pourbaix (potential-pH) diagrams for electrochemical stability. Identifies corrosion, passivation, and immunity regions using pymatgen PourbaixDiagram. |
