└── my-custom-skill/
    ├── manifest.json

Project-Level Skills

Place skills in your project's .nexuscore/skills/ directory to share them with your team via version control:

my-project/
└── .nexuscore/
    └── skills/
        └── project-conventions/
            ├── manifest.json
            └── prompt.md

Project-level skills are loaded automatically when you open the project in NexusIDE or run nexus-cli from the project directory.
