DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.233

No more frontmatter warnings for reference docs alongside agents

You'll notice
Useful3 Signal2
Agents

Reference docs sitting next to your agents no longer trigger missing-frontmatter warnings.

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.
