Skillfold is a skill manager for Claude Code and Codex that uses declarative YAML configuration to define and install custom skills.
The tool addresses the challenge of managing custom skills for Claude-based development environments in a reproducible and version-controlled way. It works by allowing developers to declare skills in YAML files, then uses a lockfile to pin exact revisions of those skills. This approach ensures that skill installations remain consistent across different environments and team members, similar to how dependency managers handle package versions in traditional software projects.
Skillfold suits developers who work with Claude Code or Codex and need to maintain a set of custom skills across multiple machines or within a team. It is particularly valuable for projects where reproducibility matters, such as collaborative development environments or CI/CD pipelines where you need identical skill configurations. The declarative YAML approach makes skill definitions human-readable and version-control friendly, allowing teams to track skill changes alongside their code.
The project shows active development with regular commits addressing bug fixes and feature improvements. Work spans across core functionality refinement, documentation updates, and tooling enhancements. The codebase demonstrates attention to both user-facing features and underlying infrastructure quality.
