One skill took coding success from 28% to 71%. Another made things worse.
Guy Podjarny and Simon Maple tested 1000+ agent skills and reveal which ones actually work, which hurt performance, and why anecdotal evidence isn't enough anymore.
Tessl Skills Registry is the first package manager for agent skills with built-in evaluations, versioning, and lifecycle management. Explore tested skills and see real performance data: https://tessl.io/registry
On the docket:
• Claude roasted Anthropic's own skill with a 27% score ("monolithic wall of text")
• Why some popular skills actually decrease agent performance
• How Tessl is bringing package managers and evals to agent skills
Whether you're creating your first skill or managing them across your dev team, this is your roadmap for making agent skills actually work.
