alirezarezvani/claude-skills: what is inside, 2026-10-11

Counted from the repository's files at commit 19392f7a0826; nothing was run. A skill meets the format when its name is at most 64 lowercase letters, digits and hyphens and its description is 1 to 1,024 characters. The token figure is the combined length of distinct names and descriptions at four characters per token. Claude Code does not load all of it: past a budget it lists skills by name only (we measured 25,289 tokens at session start with 512 skills installed, against 17,781 with 12).
