## You need

- The app activated

## You'll come away with

- Find the sharing switch and know its default
- Preview the context before you send
- Know which parts of a design are and aren't sent

## Step by step

1. **Find the switch.** Open Settings, Agent API. Allow sending design context to OpenAI when I press Send is off by default. While it is off, Send is disabled, and the conversation offers Enable design-context sharing, which switches it on in one click
2. **Preview what goes.** On a design's Instructions tab, choose Preview. It shows the context the Agent is given with each message.
3. **Know what is in it.** Your message; the design's instructions, intent, numbers and titles; references by name, kind and fingerprint, never their contents; the latest worksheet's dimensions, measurements and plan; up to 12 earlier turns of the conversation; and the results of tools the Agent runs.
4. **Choose where it is processed.** With OpenAI API (your own key), pick EU (eligible API project), the default, or Global, under Settings, Agent API. CueCrux Credits always use global processing. OpenAI Subs follow your ChatGPT account's policy.
5. **Switch it off.** Untick the setting. The app confirms: Design-context sharing disabled. Nothing more is sent until you allow it again.

## Walkthrough

The setting, its default and the field names are the app's own. The design and its values are an example.

- **Settings · Agent API:** Allow sending design context to OpenAI when I press Send = off (default); Send = disabled
- Provenance: real-code

- **Gate:** Tick the setting to allow sending. The app confirms: Design-context sharing enabled.
- Provenance: real-code

- **Preview (example design):** agentInstructions = Work in millimetres…; design = 000-001 Wall bracket, intent, revision; references = bracket-rev-a.step · STEP · sha256 5f2c… · contentsIncluded: false; worksheet = dimensions, measurements, plan; previousTurns = up to 12
- *Field names are the app's; values are examples.*
- Provenance: illustrative

- **Processing:** OpenAI API = EU (default) or Global; CueCrux Credits = Global; OpenAI Subs = Account policy
- Provenance: real-code

## What it won't do

- Results of the tools the Agent runs, such as reads of your open model, are sent too.
- Preview shows everything the Agent is given, including some local details that are not sent to OpenAI.
- Your model files are never uploaded; references go by name and fingerprint.
- Managed AI uses OpenAI; see the privacy notice.

## Covers

- What leaves your workstation (Available): Model files stay local; design context is sent only after you allow it in Agent settings, and you can preview it first. Where: In the app, Settings → Agent API; Instructions → Preview
