Questions

What do I get?

A SKILL.md file: the steps your agent follows, the data it reads from each app, the card it posts to your Briefkin board, a one-off prompt you can paste into any chat, and a suggested schedule with the cron line. The same shape as every skill in the library.

Does it need API keys or MCP servers?

No. The skill is written for your browser first: the agent opens each app signed in as you and reads the numbers off the page. Claude Code with Claude in Chrome, the Claude app and ChatGPT with their browser extensions can do that today. Every skill also carries an API or MCP route for agents that prefer it.

Is it free?

Writing a skill is free and needs no account. Installing it needs a Briefkin account, so the skill knows where to post its card. Briefkin is free during the open beta.

Which apps can it read?

Any app with a web page your agent can open: analytics, CI, issue trackers, payment dashboards, ad managers, search consoles, shops, support inboxes. Name them as you call them; the creator knows the pages and reports of the apps in the library and writes its best guess for the rest, marked as something to check once.

Can I change the card?

Yes. While the skill is written you watch the card fill in; then you pick which widgets it shows, in what order, whether it is a number with a trend, a report or a question, and you rename it. The preview is the board's own card component, so what you see is what lands.
