Evaluate a skill
Bad skills burn tokens, produce wrong output, and send you back to square one. Catching those problems early saves you time and compute. Evaluate via a GitHub URL, or run it locally from your machine.
VIA GITHUB
Analyze a repository
Paste a public repo URL and Tessl will scan it automatically. The skill gets added to the open registry for others to find and install.
Best for: Evaluating a public skill you have found on GitHub authored by other people.
Adds to the public registry where other developers can find, install, and build on evaluated skills.
VIA CLI
Review locally from your machine
Run a review directly in your terminal. Works with any local path, including private repos and work-in-progress skills.
Best for: Local skills, private repos, or work-in-progress skills you are not ready to publish yet.
Run in your terminal
npx tessl skill review ./<path to SKILL.md folder>Stays local. Results are only visible to you. Read the docs to learn more about how review evals work.
