Sanyuan-skills is a collection of production-grade agent skills for Claude Code and other AI agent terminals.
The collection addresses the need for specialized capabilities in AI-assisted workflows by packaging reusable skills that extend agent functionality. Each skill encapsulates a specific domain of expertise—from code review and tutoring to knowledge management—designed to be installed and invoked within agent terminals. The skills are built to handle complex tasks that require structured reasoning and domain knowledge, such as evaluating code against SOLID principles and security standards, or guiding learners through mastery-based instruction.
Developers should adopt these skills if they work with Claude Code or compatible AI agent terminals and need to augment their agents with specialized capabilities. The collection suits teams that want to standardize code review practices, implement structured learning approaches, or build knowledge bases from unstructured content. Individual skills can be installed independently, allowing teams to adopt only what they need. The Code Review Expert skill targets senior-level review criteria including SOLID principles, security, performance, and error handling. The Sigma skill provides one-on-one tutoring based on Bloom's 2-Sigma mastery learning framework with Socratic questioning. The Skill Forge skill itself is a meta-skill for creating high-quality skills using battle-tested techniques. Wiki Ingest compiles articles and documents into structured, cross-referenced knowledge bases. Book Study functions as a reading coach with knowledge compilation, mastery testing through Socratic questioning, spaced repetition, and cross-book querying capabilities.
The project shows active development with a focused skill set of six distinct capabilities. The codebase is organized with each skill in its own directory, suggesting a modular architecture that supports independent maintenance and iteration. The inclusion of meta-skills like Skill Review and Skill Forge indicates the maintainers are building tooling to improve the quality and consistency of skills themselves. Installation is straightforward through a standard command-line interface, and the project is licensed under MIT terms.
