18a. AI Console — bring-your-own-key (optional)

Help → AI Console… is a chat surface over the Anthropic API that can propose, or (with a second explicit toggle) dispatch, the same drawing/editing tool calls the Claude MCP bridge in §17 uses. Unlike everything else in this manual, this one feature genuinely talks to a third party over the internet — so it is off by default and gated behind its own disclosure.

• The first time you open it, a notice tells you exactly what would be sent (your typed prompt, plus a compact summary of the open document — active cell, layer list, selection counts, never the full drawing) and to where (the endpoint you configure, default https://api.anthropic.com/v1/messages). Nothing past that notice is usable until you click "I understand, enable".
• You supply your own API key, model, and (if you want a different provider or a local gateway) endpoint. The key is stored only in this browser's local storage — it is never saved into your .gds file or any autosave draft.
• Every response starts in dry run: proposed tool calls are shown in the transcript, not run. Turning on "Enable execution" is a separate, explicit step, and it resets back off every time you reopen the dialog.
• When execution is on, each tool call the model makes is dispatched through the exact same path the Claude MCP bridge uses — so it is still exactly one undo entry per call, and you can step back through it like any other edit.
• A failed request (bad key, rate limit, etc.) shows the real error from Anthropic — never a fake "done".
