GNCore

GNCore is a portable Python library of reusable AI skills. Search the catalog, inspect a skill's instructions, or export one or more standard SKILL.md folders for use with an AI assistant.

GNCore is a skills tool, not an orchestration or application-management tool. It does not scan for AI apps, install or remove files in their configuration folders, configure MCP, run models, or trigger assistant actions. The host assistant loads a skill and provides its reasoning and tools.

Install

python -m pip install gncore

Discover and use skills

gncore list domains
gncore search "machine learning training"
gncore show train
gncore export --skills train evaluate --output ml-skills.zip

The ZIP contains a SKILL.md directory for each selected skill. Copy the skill folders to the skills directory documented by your assistant, then invoke them using the slash name when supported, such as /train. GNCore never writes to assistant directories.

Export the complete catalog if desired:

gncore export --all --output gncore-skills.zip

The Python API can be used directly:

from gncore import get_skill, list_domains, search_skills

skill = get_skill("train")
print(skill.prompt)
print([domain.name for domain in list_domains()])
print([item.metadata.skill_id for item in search_skills("clean data")])

GNCore 5.0.0 includes 403 skills across 30 domain packs, with ten focused workflows per pack plus specialist skills. Browse the complete skill catalog.
