async

Quick Review

The skill addresses async processing with Symfony Messenger, a moderately complex topic that benefits from structured guidance. However, the description is extremely minimal ('Use when working with async') and doesn't clarify what specific capabilities the skill provides or when to invoke it. The SKILL.md references @REFERENCE.md for detailed documentation (which per instructions we assume exists), suggesting task knowledge is externalized appropriately. Structure is acceptable given the reference pattern, though the current file provides almost no actionable content. Novelty is reasonable as async patterns and Symfony Messenger configuration can be complex for CLI agents. The primary weakness is the vague description that would make it difficult for an agent to know when and how to invoke this skill.
