Claude Skills: I Stopped Installing Them. Here's What I Do Instead.

Nate B. Jones defines a skill as a reusable set of instructions for a particular job. Agents first see a skill's name and description, load the full instructions only when the task matches, and consult supporting files when the main instructions point to them.

Nate B. Jones warns that copying large collections from unknown repositories can introduce unsafe instructions, vague triggers and conflicting guidance. A useful skill needs a narrow purpose, a clear description and enough detail to perform the work without turning the main file into an oversized manual.

Nate B. Jones recommends treating people as the authors and auditors of the judgment encoded in skills. Existing skills should be adapted to the actual goal, and a growing collection should be reviewed for overlaps and contradictions so the agent does not average incompatible instructions into weaker results.
