Unclear It is unclear what from_plugin is used for or what user-visible behavior, if any, it enables.
What
A schema Claude Code uses internally to describe skill- and agent-like entities (packaged instructions and subagents that can be loaded and run) now includes an optional from_plugin field, alongside the existing read, color, and summary fields.
Why
The finding does not say what this field is used for, so it is not clear yet what it changes for someone using skills, agents, or plugins.
