[hessius]

Overview

Enhance the LLM prompting and barista experience for espresso profiling in the coffee-relay server.

Requirements

1. Complex Profiles
   • Expand profile creation prompts to support more complex and detailed espresso recipes (e.g., multi-stage extraction, multiple pre-infusion & blooming steps etc).
2. Barista Persona Improvements
   • Update the LLM barista persona to represent a modern, experimental barista in both style and recommendations.
3. User Information
   • After profile creation, notify user with a brief summary:
     • What was created
     • How it should be prepared
     • Why the recipe/profile is designed as such
     • Inform user of any special gear/requirements (e.g., bottom filter, specific dosage like 20g, unique preparation steps).
4. Profile Naming
   • Name all new profiles with witty or pun-heavy names, balancing creativity with clarity about the profile specifics.

Acceptance Criteria

• Profile prompts accept and handle richer recipe inputs.
• LLM persona reflects a modern experimental barista (with a touch of personality).
• Profile creation flow includes post-creation summary and requirements for the user.
• All generated profile names are witty, punny, and relevant to the recipe specifics, but not cryptic.
• Documentation is updated with sample dialogues and naming conventions.
