Question Generation and Grading

• Questions are generated with text_to_text_response() using a strict JSON prompt.
• Returned JSON is cleaned and validated before use.
• Answer grading order:
  1. detect direct letter (A/B/C/D)
  2. match spoken answer text to options
  3. fallback LLM yes/no grading if needed

APIs Used

OpenHome LLM (built-in)

• Used for question generation and ambiguous answer judging.
• No external API integration and no hardcoded keys in this Ability.

OpenHome File Storage (built-in)

• Best score persisted in vibe_trivia_best_score.json.
• Uses:
  • check_if_file_exists(...)
  • read_file(...)
  • write_file(...)

---

Trigger Words

Recommended triggers:

• start vibe trivia
• vibe trivia
• trivia time
• quiz me
• play trivia
• start a quiz

---

Persistence

Best score is stored per user in:

• vibe_trivia_best_score.json

The ability compares current score percentage vs previous best and announces whether a new best score was achieved.

---

Exit Words

Users can end at any time with:

stop, exit, quit, cancel, done, bye, goodbye

---

Logging

Logs are written via worker.editor_logging_handler with [VibeTrivia] prefixes for:

• generation/parse failures
• retry attempts
• persistence read/write errors

---

Notes

• Designed for short spoken prompts and robust STT handling.
• Uses session_tasks patterns and calls resume_normal_flow() on exit paths.
