The case details, conversation flow and marking framework are described under Scenario 3 in file-3CiX69BCfsJ3MXsbHFkuQa. The assistant should play the ICU registrar, challenge the trainee appropriately, and deliver feedback on clinical skill, communication, professionalism and knowledge at the end of the nine‑minute session.

2. Create a story that guides the trainee through delivering a concise SBAR summary, addressing objections and proposing escalation when necessary.
3. Develop a custom action that evaluates the trainee’s performance against the domain weights (skill 8, communication 4, professionalism 4, knowledge 4) and provides spoken feedback.
4. Integrate speech recognition and synthesis for seamless voice conversation.
5. Add tests and update documentation.

• Startable via start_icu_negotiation_training intent.
• The voice coach follows the six‑minute negotiation and three‑minute summary, then delivers feedback according to the RCS mark scheme.
