What it does
The repository collects the skills published in the AI Skill of the Week newsletter on Substack. The `skills/` folder now holds sixteen, each in its own folder with a `SKILL.md`: an email subject line optimizer, a Substack note generator, a personal MBA generator, a LinkedIn hook generator, an idea extractor, a growth idea action plan, a content miner, an SOP writer, a Substack optimizer for search and AI answers, an honest thinking partner, an AI standup, a cold outreach personalizer, a humanizer, a mock interview simulator, a self-grading skill and a proposal generator. Each skill is self-contained: take the file, save it as `.md` and upload it to Claude. The README describes the claude.ai route: open the file, click Raw, save it and upload it in settings. For Claude Code, copy the folder of the skill you want into `~/.claude/skills`. The author adds a new skill every week.
Who it is for. Newsletter authors, marketers and consultants who want ready skills for emails, posts and proposals with no setup from scratch.
Good fit when
- An email subject line has to be checked and several options produced through `001-email-subject-line-optimizer`
- Cold emails are personalized for each recipient with `012-cold-outreach-personalizer`
- A practice run before a job interview goes through `014-mock-interview-simulator`
- A repeating process is written up as an SOP with `008-sop-writer`
- A client proposal is built with `016-proposal-generator`
Not a fit when
- You want a coding ruleset: the skills target texts, emails and plans and not programming
- You want a one-command install: files are taken by hand or folders copied, with no skill-manager package
- You need a method proven in your niche: each skill follows the newsletter general recipes and will need adapting to your task
Example request
Take the 001-email-subject-line-optimizer skill and suggest five subject lines for the launch email of our new courseLimitations
The repository is meant as a newsletter archive, no license is stated and the author does not set out reuse rights. The skills are written for claude.ai with English texts, so Russian prompts have to be added yourself. There are no install commands, plugin or manifest: the README describes uploading a `SKILL.md` through Claude settings, and in Claude Code you copy the folder by hand. README descriptions are general, and the detailed use case breakdown of each skill appears only in the newsletter itself on Substack.
How to disable. Delete the skill folder from `~/.claude/skills` or the file from Claude settings. Nothing else gets installed.
