Unknown toolsIt allow-lists tool names Claude Code does not ship, which usually means a typo.

What it says it does

Write, optimize, and grow Substack content — both newsletter issues (email-first) and web posts (web-first articles/essays). Covers ghostwriting with voice matching, Substack algorithm optimization, Notes strategy, email formatting, SEO, growth tactics, and monetization planning. Use when the user mentions Substack, newsletters, write a newsletter issue, Substack post, Substack article, web post on Substack, evergreen content, SEO for Substack, newsletter growth, Notes strategy, ghostwrite for, match someone's voice, write in the style of, newsletter monetization, paid subscribers, or any task involving Substack as a platform. Also trigger for general article/newsletter writing even if Substack isn't named explicitly, or when the user wants to adapt existing content (blog post, talk, thread) into newsletter or web post format. Do NOT use for generic blog post writing without a newsletter/Substack context (-> See samber/cc-skills@technical-article-writer skill).

Put this measurement in your README

A badge carrying how many listings this index holds from the repository and how many pass every static structural check. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.

SkillWorks badge

[![SkillWorks](https://toolproof.kynth.studio/badge/skillworks/samber/cc-skills.svg)](https://skillworks.kynth.studio/?q=samber%2Fcc-skills)

Would rather not hotlink us? Every badge is also served in shields.io’s endpoint schema, so shields renders the image and your readers never talk to our domain:

Published by Toolproof, the masthead over this index and eight others. The method behind the number is at toolproof.kynth.studio/methodology, and the whole thing is readable as JSON with no key at /api.
