What API reference skills agree on

149 skill files read, by 159 of the 198 authors on this shelf whose files we hold, 2026-09-06

When API reference authors say to reach for one

The situations these authors wrote into their own files, counted out of the same 159 authors, with the skills that name each one

How API reference skills are built

389 skill directories by 182 authors, read from their repositories’ own file trees 2026-08-05

The middle bundle among those shipping files is 2 files, 17.3 KB beside SKILL.md

Counted by distinct author, same as above, so one author publishing forty template copies counts once. SKILL.md itself is not counted as a file, so a single-file skill is one where that file is the whole skill.

The shape

  1. SKILL.md is the whole skill72 of 182 authors, 179 of 389 skills
  2. files ship beside it110 of 182 authors, 210 of 389 skills
