 ## Skills
 
 | Skill | What it does |
 | --- | --- |
 | [good-readme](skills/good-readme/SKILL.md) | Writes or improves a README.md for an open source project, based on Evil Martians' real experience of successfully promoting PostCSS, Nano ID, and other popular projects. Companion to [How to make your open source popular](https://evilmartians.com/chronicles/how-to-make-your-open-source-popular). |
 | [llms-visibility](skills/llms-visibility/SKILL.md) | Makes a site visible and readable to LLMs and AI agents. Covers Markdown routes, `Accept` content negotiation, `llms.txt`, and crawler signals in `robots.txt`. Pushes back on popular patterns that don't work. Companion to [How to make your website visible to LLMs](https://evilmartians.com/chronicles/how-to-make-your-website-visible-to-llms). |
-| [secure-npm-package](skills/secure-npm-package/SKILL.md) | Sets up a secure npm release process — Trusted Publishing with staged publishes from GitHub Actions, hardened workflows, dependency cooldowns — and walks the user through the manual npmjs.com and GitHub settings with links resolved for their repo. |
-| [skills-visibility](skills/skills-visibility/SKILL.md) | Publishes a catalog of agent skills and makes it discoverable and installable by AI coding agents — a `.well-known` discovery index, self-hosted archives with integrity digests, and several install commands. Pushes back on pointing an index at raw GitHub URLs. |

Companion to [Ship agent skills like packages: discovery index, digests, and install sources](https://evilmartians.com/chronicles/publishing-agent-skills-discovery-index). |
 | [tailwind-best-practices](skills/tailwind-best-practices/SKILL.md) | Writes and audits Tailwind CSS with the five practices that keep a fast-to-write codebase maintainable: design tokens over magic values, short and consistently ordered class lists, semantically grouped tokens, and fixed variants for design-system components instead of arbitrary className props. Companion to [5 best practices for preventing chaos in Tailwind CSS](https://evilmartians.com/chronicles/5-best-practices-for-preventing-chaos-in-tailwind-css). |

 # Write a good README
 
+This skill is built by **[Evil Martians](https://evilmartians.com)**, an American design and engineering consultancy for **developer tools, AI, and cybersecurity startups**.

 Apply the structure below when creating or improving a README. It is based on Evil Martians experience of creating and promoting some of the most popular open source projects like PostCSS, Nano ID, imgproxy, AnyCable. Companion to <https://evilmartians.com/chronicles/how-to-make-your-open-source-popular>.
 
 **Never invent facts.** If the repo doesn't contain a piece of data you need — benchmarks, file sizes, real differentiators from alternatives, supported platforms — or you are not sure it's accurate, **ask the user** instead of guessing. A README with fabricated numbers is worse than one without numbers.

 Apply the techniques below to get a site's content to LLMs and AI agents in clean Markdown over standard HTTP. Companion to <https://evilmartians.com/chronicles/how-to-make-your-website-visible-to-llms>.
 
 Most of these are emerging conventions, not committed standards. No major provider has formally promised to read `llms.txt` or `.md` routes. Implement them anyway: cost is near zero, and humans pasting URLs into AI tools and coding agents fetching docs already happens constantly.

 An agent skill is a `SKILL.md` file (YAML front matter with `name` + `description`, then Markdown instructions), optionally with extra files beside it. Publishing one skill is easy. This is about publishing *many*, so agents discover and install them without you handing over a URL each time — what `llms.txt` does for pages, done for skills.
