How can you achieve 50% improvements in agent skills?
Simply improving the skill description can yield 50% performance gains. Specific descriptions that include both what the skill does and when to use it prevent incorrect triggering and optimize activation.
- “I have seen 50% improvements just by improving the description.”
- “Include both the "what" and the "when" in the description.”

Why should you avoid writing overly comprehensive skill instructions?
Research shows longer, more comprehensive instructions with too much context actually hurt agent performance. Instead, write concise directives and lead with examples, as a 5-line code snippet beats a 5-paragraph explanation.

What's the most common problem to fix when testing agent skills?
Most problems during testing are in the skill trigger, not the instructions, so fix the description first. Test with 10-20 prompts, run 3-5 trials per prompt, and use clean environments to isolate failures.
