What
A skill is a packaged set of instructions for a particular kind of task. The Skill tool is how Claude uses one. Its description, which tells Claude how to use it, can now say "Available skills appear in a listing from the system with one-line descriptions." The earlier wording, "a system-reminder listing", is still built as a second version, and Claude Code picks one of the two. A system-reminder is the tag Claude Code wraps around notes it adds to the conversation.
The stock Skill description captured under v2.1.323 differs from the one captured under v2.1.322.
Why
This is part of a wider rewording across several of Claude's tool descriptions, which now say "from the system" instead of naming system-reminder tags.
