+## Task 5: Pass keywords to transcription adapters - COMPLETE
+
+Added Keywords support to transcription adapters:
+- Added `Keywords []string` to transcriber.Config struct
+- Updated `ToTranscriberConfig()` to pass keywords from config
+- OpenAI adapter uses keywords in `Prompt` field (initial_prompt parameter)
+- Groq transcription adapter uses keywords in `Prompt` field
+- Groq translation adapter uses keywords in `Prompt` field
+- Mistral and ElevenLabs adapters ignore keywords (APIs don't support initial_prompt)
+
+Key decisions:
+- Keywords joined with ", " to form a single string for the Prompt field
+- Whisper uses this as "initial_prompt" to help with spelling/terminology
+- Only added to adapters that clearly support it (OpenAI/Groq via go-openai lib)
