Solar Return plugin

This is a skill-only Agent Plugins 1.0 package. It bundles the same calculator and instructions as solar-return.zip; it does not host a calculation API, supply Python, install dependencies or override host permissions.

Read and approve code/dependency execution in your selected environment. If the host cannot execute the calculator, it must say so and may interpret an explicitly supplied, verified result JSON instead. Installing a plugin does not prove the calculator ran.

The plugin files are prepared for supported local/import workflows. They have not been installed or accepted in every product, and this is not a listing in a public plugin directory. Workspace imports and local plugins can require administrator approval.

skills/solar-return/ is generated from the repository's canonical solar-return/ folder. Do not edit this generated copy. Rebuild with python3 tools/package_plugin.py from the repository root. Original GNU AGPL v3 and author attribution are preserved.
