Shelves Performance & cost

Token & API cost

317 rows from 115 repositories

The bill an agent runs up, which is a performance problem with a currency symbol.

What Token & API cost skills agree on

77 skill files read, by 84 of the 95 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. Near-identical wordings are grouped and the other wordings are shown, so the grouping is yours to check.

When Token & API cost authors say to reach for one

The situations these authors wrote into their own files, counted out of the same 84 authors, with the skills that name each one

How Token & API cost skills are built

281 skill directories by 105 authors, read from their repositories’ own file trees 2026-08-05

The middle bundle among those shipping files is 3 files, 11.5 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 skill49 of 105 authors, 129 of 281 skills
  2. files ship beside it56 of 105 authors, 152 of 281 skills
  3. executable scripts ship inside20 of 105 authors, 32 of 281 skills
