Skills
Free skills for coding agents.
An agent skill is a saved set of instructions your coding agent follows for a particular job. These are the ones I’ve made and use: free, open to read before you run them, and honest in their READMEs about what has and hasn’t been tried.

Launch readiness.
You point the skill at an app you’ve built and it tells you what is not ready for real users. It runs your project’s own build, typecheck, lint and test commands, then Claude Code’s security review, Gitleaks for committed credentials, OSV-Scanner for vulnerable dependencies, Supabase’s own advisors and Lighthouse where they apply. It reads the code for what tools miss, asks you what no tool can know, and writes a report marking every check Ready, Fix before launch, Fix soon or Could not check. Every fix comes with a prompt you can paste into your agent.
Fifteen sections: the app builds and runs, secrets and dependencies, authentication and accounts, Supabase or another backend, payments, paid external and AI services, product completeness, phones and browsers and accessibility, speed, being found and shared, privacy and user data, monitoring and recovery, ownership and release, mobile apps, code health. The ones that do not apply are skipped.
It asks before installing anything, never prints a secret, changes nothing in your project, and won’t tell you your app is secure.

A search plan.
For a service business getting into search engine optimisation and AI answers. The skill asks about your own business — what you’ve learned, what people ask you over and over, what they misunderstand, what you could find out that nobody knows — then works through who you are reaching, what you can sustain and what is already published, and turns the answers into a plan of what to make and in what order.
Twenty questions in six phases. The plan names what only you could publish, who would reference it, where you need to open a keyword tool yourself, and what to watch that is not a ranking.
It won’t write the plan from your industry or your URL, and won’t invent expertise you didn’t give it. If there isn’t yet something worth finding, it says so.

Video to article.
It asks about your set-up once: where you post, how to reach the videos, where the words come from, and which article on your site to copy. Then it pulls your recent TikToks, Reels or YouTube videos and what you said in them, decides whether each piece is a build-log entry or a standalone article, rewrites the speech as prose for someone who arrived from a search, draws the figures for the page in your site’s own style instead of screenshotting the video, checks every number against a source, wires the page into your site and records where it went. On a Claude plan with scheduled tasks, it can run weekly and send the pages as a pull request.
A set-up conversation, then six steps: decide what each piece becomes, get the videos and the words (three routes per platform, from pasting links to the official APIs), adapt the speech, follow your site’s page pattern, draw pictures that earn their place, wire the page in, then check and record. The picture rules came from a real review: never a screenshot of the video’s cards, never a picture of something the page could render, one figure per idea, a photograph only when it shows the subject, and every drawn figure looked at on a phone before it ships.
It won’t paste a transcript onto a page, keep a number it cannot source, invent a quotation or a result, or deploy anything by itself.
