Unclear The maximum name length is not shown.

What

Frontmatter is the block of settings at the top of a skill or agent file. Its name field now has a maximum length. Before, a name was rejected only if it was missing, started with "-" or contained ":".

A name over the limit is now handled in one of two ways:

  • rejected with an error saying names must be at most a set number of characters, with a matching error for agent files
  • ignored, with a warning that it is over the limit
Why

Skills or agents you already have with long names may stop loading or lose their name. Shorten long names if one goes missing.
