Ask Targets
The engine handoff registry — direct prefill vs. copy-to-clipboard, the field schema, and the canonical machine-readable registry.
The registry
An Ask Target is an AI engine a Cited Ask can be handed to. Each target declares how to open the engine with the prompt.
Field schema
| Field | Meaning |
|---|---|
id |
Stable engine key (e.g. chatgpt) |
label |
Display name |
method |
direct (URL prefills the prompt) or copy (copy prompt, open home) |
url |
direct: a template with {q} = URL-encoded prompt. copy: home URL |

Clipboard-fallback contract
For copy targets, the required behavior is:
- Open the engine’s home URL synchronously, on the user gesture — this is what lets pop-up blockers allow the new tab/window.
- In parallel, write the prompt to the clipboard.
- Prompt the user to paste it into the engine.
This exists for engines without a working prompt-prefill URL of their own (currently DeepSeek, Gemini, and Copilot).
Canonical registry
The canonical machine-readable registry is published at /protocol/targets.json, so any implementer stays correct when an engine changes its URL scheme rather than hardcoding a copy that can drift.
Roadmap (v1.x): a “submit your engine” contribution process for adding new targets to the registry.
