typecaast

Add or change a Typecaast timeline step type end-to-end. Use when the user wants a new kind of timeline event (e.g. "add a 'poll' step", "support pinned messages", "add a 'voice-note' step type") or to rename/reshape an existing one. Walks every touchpoint — schema, engine, every skin's capabilities, the builder UI, examples, tests — and the mandatory changeset + release so the playground and npm stay in lockstep.

Author a new Typecaast skin from a reference screenshot, a platform description, or a captured draft. Use when the user wants to add a chat/UI skin to Typecaast (e.g. "make a Signal skin", "build a Teams skin from this screenshot", "turn this captured draft into a skin"). Two output paths — a hand-written component skin (Slack/Discord pattern, full fidelity) or a captured slot-template skin (faster, lower fidelity) — pick based on the input you have.
