condition-setup

Set up conditions for PINA problems. Covers data types (LabelTensor, Graph, PyG Data), time series conditions, binding equations to domains, and data-driven input→target mapping.

create-problem

Entry point for creating PINA problems. Routes to sub-skills based on problem type (data-driven vs physics-driven), problem class selection, domain setup, equations, conditions, and discretisation.

2026-07-17

create-skill

Create, modify, and improve PINA skills. Use when the user wants to create a new skill for PINA development guidance, edit an existing PINA skill, or add cross-tool compatibility (opencode, Claude Code, Codex CLI) to a skill. Covers skill directory structure, SKILL.md front matter conventions, symlinks for Claude Code compatibility, and updating AGENTS.md for Codex CLI.
