What
A markdown file in a project's agent directory no longer produces "No frontmatter block found" or "No description in frontmatter" warnings unless its frontmatter actually declares a name. Files without one are reference documents the runtime skips anyway.
Details
The related error about a shell value now truncates the offending value to 64 characters before printing it.
Evidence
No description in frontmatter. A description helps users and Claude understand when to use this
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
