Plugin plugin.json manifest fields that accept paths now clearly state whether they replace or extend the default auto-loaded directory.
Details
Fields that fully replace the default directory (e.g., agents, commands, output-styles, themes) now document: "When set, the <name>/ directory is not auto-loaded — list its files here if you want both."
Fields that load in addition to the default (e.g., the extra skills path) now document: "Loaded in addition to the skills/ directory."
Previously, descriptions used "in addition to those in the <name>/ directory" uniformly, which was ambiguous.
Evidence
New .describe() strings (search for "When set, the agents/ directory is not auto-loaded")
