build-connector

Gets Claude talking to a tool nobody built an official connector for. Works out what the system is, checks the Claude connector directory for an existing connector first, and when there isn't one connects the tool through Zapier — never by hand-building against a raw API — with credentials handled safely and approval gates on anything that writes. This is what turns "my ERP isn't supported" into an afternoon. Use this whenever the owner names a tool that isn't connected — including phrasings like "can you connect to my," "make my tools talk to each other," "there's no API for this," "pull data out of my field service software," "I use ServiceTrade and it's not on the list," or "is there any way to get at this data." Reach for it whenever an unsupported system is blocking something else.

Compatible isn't the same as safe. These verdicts only say whether a skill's files follow Microsoft's documented load rules. The checker reads files and never runs them, and it doesn't review what a skill or its scripts actually do. Read a skill's instructions and scripts before you add it to an agent.
