Evaluation notes

What to check before installing

Install one skill at a time

The safest installation path is narrow: pick one skill, run one task, inspect the output, and only then add it to your normal agent workflow.

  • +Copy the install command from a skill decision page.
  • +Run the first task in a sandbox repo or low-risk branch.
  • +Review what files, tools, and external services the skill may touch.

Use installability as a quality signal

A skill with a clear install path is easier to evaluate. Missing install commands are not automatic dealbreakers, but they add review work.

  • +Prefer skills with a repository and clear docs.
  • +Check license and maintenance freshness.
  • +Keep notes on what the skill did well and where it failed.

FAQ

Common questions

Can I bulk-install many skills at once?

You can, but it is harder to debug. For production workflows, install and validate one skill at a time.

What if a skill has no install command?

Treat it as a manual-review candidate. Open the repository, inspect the instructions, and avoid production use until the install path is clear.
