What Errors & stack traces skills agree on

125 skill files read, by 135 of the 162 authors on this shelf whose files we hold, 2026-09-06

Counted by distinct author, so one author publishing three of these counts once. Where a claim sits in fewer files than authors, that is said: a claim held by forty authors across three files is one file people copied, not forty people who agreed.

When Errors & stack traces authors say to reach for one

The situations these authors wrote into their own files, counted out of the same 135 authors, with the skills that name each one

How Errors & stack traces skills are built

302 skill directories by 171 authors, read from their repositories’ own file trees 2026-08-05

The middle bundle among those shipping files is 2 files, 16.5 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 skill91 of 171 authors, 162 of 302 skills
  2. files ship beside it80 of 171 authors, 140 of 302 skills
