One of 3 test cases the skill fixed. Same model, same prompt, with and without the skill.

Prompt

In an async Rust log aggregation service, producers generate log entries rapidly while a single disk-writing consumer writes them out. Developers are tempted to use an unbounded channel to prevent producer calls from blocking. Provide a recommended channel implementation that prevents unbounded memory growth.
