An open directory for the Agent Skills format
A web skill is plain-English instructions that teach a browser agent how to get something done on one specific site — cancel a subscription, check out as a guest, explain an invoice. Written by site owners, by the community, and by us.
Skills live under the site they work on. Every one has its own page.
Everything here was reviewed before it appeared.
Storefront
shop.storefront.example
Fills a Storefront guest checkout (shipping + contact) from details the user supplies, then hands the payment step back to the user. Scoped to the checkout wizard only.
Acme Billing
billing.acme.example
Reads an Acme Billing invoice and explains the charges in plain English. Knowledge-only: it reads and explains, it never modifies anything.
Acme Billing
billing.acme.example
Cancels a recurring subscription on Acme Billing. Drives the cancel flow and stops at the final confirm, handing the consequential last click back to the user.
DevDocs
devdocs.example
Finds and summarises API documentation on DevDocs. Knowledge-only on the page side; prefers the site's remote MCP server for live symbol lookup when the user has enabled it.
Skills are filed under the site they work on, so start where you were going anyway.
Every skill is plain English you can read end to end, with exactly what it is allowed to do listed up front.
The browser checks this directory as you navigate and offers the skill when it fits. Nothing runs until you say so.
Serve a skill from your own domain at /.well-known/agent-skills/ and the browser reads it directly — no directory in the middle. Do that, and we verify your domain automatically and mirror it here so people can find it.
GET /.well-known/agent-skills/index.json
