Skillable is scalable.

When method, tool, fixture, and proof travel together, another agent can repeat the work.

The package carries the work.

Instructions, scripts, evals, assets, and gates become a portable operating surface.

Retrieval helps. Packaging scales.

Vector search and automation are useful layers. They do not replace the procedure.

Reuse gets cheaper after the gate exists.

The first skill costs more than a prompt. Every reuse after that compounds.

Make the work portable.

Write the skill, add one helper, prove one command, publish the artifact.
