What is it?

SkillNet covers the lifecycle of reusable agent skills. It searches a hosted public skill library by keyword or semantic intent, downloads skill folders from GitHub into local workspaces, and generates new skill packages from prompts, repositories, documents, or execution traces.

For existing skills, SkillNet evaluates safety, completeness, executability, maintainability, and cost awareness without running their scripts. Its analysis step extracts capabilities and usage scenarios from a local skill folder and builds a graph of directed compose_with and undirected similar_to relations. A routing step then selects up to k local skills for a task, returning a reason for each choice.

The project is a Python package (skillnet-ai, Python 3.10+) with an SDK, a CLI, a REST search API, and a local browser UI launched with skillnet ui. Create, evaluate, and analyze call an OpenAI-compatible endpoint, and routing uses Claude or Codex Agent SDKs.

Key features

  • 01Keyword and semantic search over a hosted public skill library.
  • 02Download skill folders from GitHub into local directories.
  • 03Generate skill packages from prompts, repos, documents, or traces.
  • 04Evaluate skills on five quality dimensions with level and reason.
  • 05Build a local relationship graph and index from a skills directory.
  • 06Route tasks to local skills with selection reasons via SDK or CLI.
