Your AI agent skills are an unversioned dependency
Your AI agent skills are an unversioned dependency A skill is a prompt that lands in a model's system context. Most teams install them the way we installed libraries in 2009: clone a repo, copy a folder, hope nobody touches it. Then the folder drifts and the agent quietly loads something nobody reviewed. I maintain Skillporter, a package manager for AI agent skills. This is the design problem…
Your AI agent skills are akin to unversioned dependencies that can cause compatibility issues across different tools and platforms. Most teams install these skills manually, copying files into separate directories for each AI agent, leading to a cluttered workspace and potential conflicts. Skillporter, a package manager for AI agent skills, aims to address this design problem by introducing a manifest-based approach.
With Skillporter, a commit-able manifest lists the skills and target harnesses, and a resolution step fetches the sources, validates their structure, and ensures a single installation per harness path, while shared paths are written only once. This lockfile contains a content hash per skill, enabling rollback in case of a bad upstream change.
The package manager's exit codes distinguish between failed checks and checks that couldn't run, ensuring accurate pipeline execution. Skills, being supply chain inputs, should be scanned for known dangerous patterns and reported with a risk score. However, they cannot prevent novel prompt injections executed by the agent at runtime.
The MCP mode, designed to be called by a model, restricts certain actions unless started with a specific flag. Skillporter is a simple, single-maintainer tool, focusing on making skills deterministic, visible, and reversible.
