Broken YAML frontmatter is reported instead of silently ignored

Skills

A skill, command or agent with broken YAML frontmatter now logs an error instead of loading silently.

What

A skill, command or agent file whose YAML frontmatter fails to parse now logs an error naming the problem, where previously the failure was discarded and the file was loaded as if it had no frontmatter at all.

Details
  • The skills loader also emits a telemetry event when this happens.
Evidence

failed to parse and was ignored:

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
