- **Copilot SDK version 1.1.0 or later.** The server checks the version your SDK announces against your own manifest's `sdkMinVersion` — if your build is older, the copilot stays off with the reason `sdk_too_old` (section 10). - A **Copilot Assistant-type channel** already created on your tenant, with the **copilot turned on** from the Platform → Channels → that instance → "Copilot" (manual 24; the activation toggle is described in the operator's manual, number 58, section 2). It's its own channel type, with its own plan limit — manual 62 (Plan capabilities and limits) explains that limit and what happens if the channel becomes "out of plan". - The **chat widget** already installed on your site (manual 06) — the copilot mounts *alongside* it, never in its place. - Access to **edit your site's HTML/JS**, to add the anchor attribute to the fields and buttons you want the copilot to be able to touch (section 4).
