Workflows is a programmable execution graph — not a no-code automation editor. 228+ blocks. Type-aware variable references. Sub-agents in their own sandboxes. Triggers from 50+ services.
Typed inputs and outputs. Conditional sub-blocks. Basic / advanced modes. Extensible registry — add a new one.
Webhooks and polling for Gmail, GitHub, Calendly, Cal.com, Fathom, Gong, Sheets — workflows start when reality changes.
References resolve at execution. Coercions live in tools.config.params — not tools.config.tool.
Conditional visibility. Dependency clearing. Per-mode UI. Hosted-key OAuth. The block authors don't reinvent the form layer for every new tool.
