Architecture & codebase

12,940 rows from 2,782 repositories

The shape of a system, and finding your way around one.

What Architecture & codebase skills agree on

1,011 skill files read, by 858 of the 1,304 authors on this shelf whose files we hold, 2026-09-06

The middle one of the 120 measured here is ~1.6k tokens long, counted with cl100k_base

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 Architecture & codebase authors say to reach for one

The situations these authors wrote into their own files, counted out of the same 858 authors, with the skills that name each one

How Architecture & codebase skills are built

11,646 skill directories by 2,519 authors, read from their repositories’ own file trees 2026-08-05

The middle bundle among those shipping files is 3 files, 13.7 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 skill904 of 2,519 authors, 5,658 of 11,646 skills
