Reads the public registers a company has to file in before it ships, through programs in the hedwigai MCP's read-only shell.
Before you start
This skill uses the hedwigai MCP's bash tool. If they aren't available, tell the user to connect hedwigai — in Claude, from https://claude.ai/directory/hedwigai; in Claude Code, /plugin marketplace add un-seen/hedwigai-skills then /plugin install hedwigai@hedwigai; anywhere else, add https://mcp.hedwigai.com/ as a remote MCP server.
programs list shows what each program bills. Run a study with no arguments, or <program> --help, before the first call; don't guess flags. Output is JSON: use jq in the same shell, and keep work in /tmp, the only writable place.
Which register says what
| Signal | Study | Read it as |
|---|---|---|
| A new subdomain went live | webcertificates search <domain> |
Certificates for names at or under the domain, newest first. A new api., checkout. or status. is something going live this week. Also answers "who just joined" a platform with per-customer subdomains, such as myshopify.com |
| A product name and what it will sell | us-trademarks search <company> |
Applications matched on who filed. Read the goods and services; an "intent to use" filing means nothing is on sale yet. Needs a free USPTO key on the account, and says so if missing |
| Hardware that transmits | fcc search <company> |
A grantee code means the company has committed to shipping a radio device. fcc ids is in preview and doesn't currently return |
| A medical device | fda search <company> |
Device establishment registrations, filed before a device can be sold in the US |
