agnt-plugin-builder

End-to-end workflow for creating, building, installing, and hot-reloading AGNT plugins entirely from chat. Use this skill whenever the user asks to 'build a plugin', 'create an AGNT plugin', 'add a new tool to AGNT', 'integrate X with AGNT' (where X is an API or service), 'make a plugin for [service]', or wants to extend AGNT with custom workflow nodes, triggers, or integrations. Also trigger when the user mentions editing, updating, rebuilding, or reinstalling an existing plugin, or says things like 'turn this API into an AGNT tool', 'wrap this endpoint as a plugin', or 'add [service] to my AGNT workflows'. Covers scaffolding the dev folder, writing manifest.json + ES-module tool code, running build-plugin.js, installing via /api/plugins/install-file, and reloading via /api/plugins/reload — all from a single chat session with zero manual terminal work.
