Skill++ rewrites agent skill metadata to fix router selection errors

Skill++ rewrites the name and description of each new agent skill so that routers pick the right skill, according to Elvis Saravia, who reports the method on X. The rewritten metadata states what a skill supports, how it differs from its closest existing skill, and what it excludes.

Saravia says the method needs no router training or labeled data.

In a library of 731 skills tested over ten sessions, routers selected every required skill for 76.3% of queries with the rewritten metadata, up from 36.4% with the original metadata, according to the same report. The report does not describe the query set or the routers used.
