Feishu Card

This lets you build and send interactive message cards in Feishu with buttons and selectors, then handle the callbacks when users click them. You'd use it for morning standup confirmations, alert handling, task approvals, anything where you need a quick response inside a chat instead of spawning a whole form. The documentation is thorough with token caching built in and practical examples for buttons, dropdowns, and markdown formatting. One nice touch is the explicit guidance on updating cards in place rather than spamming new messages. The card JSON has to be stringified before sending, which is a bit awkward but that's Feishu's API design, not this skill's fault.
