async-drop

Quick Review

This skill provides a clear guide to the AsyncDrop pattern in Rust with good practical examples and rules. The description adequately covers when to use it (AsyncDropGuard, trait implementation, async resource cleanup). Task knowledge is strong with code examples, the trait definition, essential rules table, and the with_async_drop_2! macro. Structure is clean with references to additional files for patterns, gotchas, and helpers. However, novelty is moderate - while AsyncDrop is a Rust-specific pattern, the skill essentially documents an existing library pattern rather than solving a complex multi-step problem. A CLI agent with Rust knowledge could likely handle basic async cleanup scenarios, though this skill does provide valuable consolidation of the pattern's rules and best practices.
