Choose a skill for the job, not the collection.
A short checklist for finding a better fit for your personal agent.
Name the result
“Help with documents” is broad. “Turn these notes into a Word report with a consistent format” gives you a much better starting point.
Check the environment
Read the supported client, required tools, dependencies, and setup instructions. A skill file being readable by your agent does not prove that every script and dependency will work.
Look for evidence
Prefer a clear source, specific examples, and an honest description of limitations. In OpenYourAgent, a source summary is not an independently verified recommendation.
Try one small task
Test with an input you understand and can check easily. Notice where you needed to intervene, and whether the result was actually useful.
Keep what helps
Add a capability when it solves a repeated need. Revisit it if the underlying product changes or the instructions stop working.
