Skillflag CLI Convention & Library

Skillflag is a CLI convention and library for bundling, listing, and installing agent skills directly from a CLI tool's repository without relying on third-party registries. It provides a standardized `--skill` flag interface (`list`, `show`, `export`) for agents to discover and integrate capabilities. The current stable version is 0.1.4, indicating early development and a nascent ecosystem. As a new project, release cadence is currently irregular, but recent updates suggest active development. Its key differentiator is decentralizing skill discovery, enabling agents to parse skills directly from a tool's published repository, akin to a `--help` or `manpage` for skills, reducing overhead and central points of failure associated with traditional skill registries. It targets Node.js (>=18) environments and ships with TypeScript types.
