dschlueter 054f867a8a Fix podcasts generating in English + failing with invalid JSON
Two root causes, both fixed in the bind-mounted podcast prompt templates
(prompts/podcast/*.jinja):

1. Language: the episode profile's `language` field IS passed to both
   podcast_creator templates as {{ language }}, but the stock templates never
   reference it — so podcasts came out English (driven only by the English
   stock briefings/speakers), then read aloud by the German-locked Chatterbox
   TTS = "English with a German accent". Added a CRITICAL LANGUAGE REQUIREMENT
   block keyed on {{ language }} to both templates; now `language: "de"`
   actually forces German. Verified end-to-end: a full run produced a 44-line
   all-German transcript + audio.

2. Invalid json output failures: qwen3.5:27b is a thinking model; on long
   segments the <think> block ate the response-token budget and truncated the
   JSON. Prepended /no_think to both templates (~3x faster, valid JSON).

Templates are bind-mounted read-only via docker-compose (directory mount, so
edits survive a container restart without inode-staleness). Bundled briefings
and speaker backstories were also translated to German to reduce drift.

Known limitation documented: feeding an entire book (~70k tokens) as podcast
content makes each of the 6 LLM calls take ~3.5 min and is unreliable; use a
shorter source or summary. Confirmed working with concise content.

You are an AI assistant specialized in creating podcast transcripts.
Your task is to generate a transcript for a specific segment of a podcast episode based on a provided briefing and outline.
The transcript will be used to generate podcast audio. Follow these instructions carefully:
First, review the briefing for the podcast episode:
<briefing>
{{ briefing }}
</briefing>
The user has provided content to be used as the context for this podcast episode:
<context>
{% if context is string %}
{{ context }}
{% else %}
{% for item in context %}
<content_piece>
{{ item }}
</content_piece>
{% endfor %}
{% endif %}
</context>
The podcast features the following speakers:
<speakers>
{% for speaker in speakers %}
- **{{ speaker.name }}**: {{ speaker.backstory }}
Personality: {{ speaker.personality }}
{% endfor %}
</speakers>
Next, examine the outline produced by our director:
<outline>
{{ outline }}
</outline>
{% if transcript %}
Here is the current transcript so far:
<transcript>
{{ transcript }}
</transcript>
{% endif %}
{% if is_final %}
{% if speakers|length == 1 %}
This is the final segment of the podcast. Make sure to wrap up the presentation and provide a conclusion.
{% else %}
This is the final segment of the podcast. Make sure to wrap up the conversation and provide a conclusion.
{% endif %}
{% endif %}
You will focus on creating the dialogue for the following segment ONLY:
<segment>
{{ segment }}
</segment>
{% if speakers|length == 1 %}
IMPORTANT: This is a SOLO podcast with only ONE speaker ({{ speaker_names[0] }}). Do NOT invent or add any other speakers.
All dialogue entries must use "{{ speaker_names[0] }}" as the speaker name.
Follow these format requirements strictly:
- Use ONLY the speaker name "{{ speaker_names[0] }}" for all dialogue entries.
- Do NOT create or invent any additional speakers.
- Stick to the segment, do not go further than what's requested. Other agents will do the rest of the podcast.
- The transcript must have at least {{ turns }} dialogue segments from the speaker.
- The speaker should present the content in an engaging, educational manner.
{% else %}
Follow these format requirements strictly:
- Use the actual speaker names ({{ speaker_names|join(', ') }}) to denote speakers.
- Choose which speaker should speak based on their personality, backstory, and the content being discussed.
- Stick to the segment, do not go further than what's requested. Other agents will do the rest of the podcast.
- The transcript must have at least {{ turns }} turns of messages between the speakers.
- Each speaker should contribute meaningfully based on their expertise and personality.
{% endif %}
```json
{
"transcript": [
{
"speaker": "[Actual Speaker Name]",
"dialogue": "[Speaker's dialogue based on their personality and expertise]"
},
...
]
}
```
Formatting instructions:
{{ format_instructions}}
{% if speakers|length == 1 %}
Guidelines for creating the transcript:
- Ensure the presentation flows naturally and covers all points in the outline.
- Ensure you return the root "transcript" key in your response.
- Make the content sound engaging and educational.
- Include relevant details from the briefing.
- Break up the content into digestible segments with natural transitions.
- Use appropriate transitions between topics.
- Match the speaker's dialogue to their personality and expertise.
- This is a whole podcast so no need to reintroduce the speaker or topics on each segment. Segments are just markers for us to know to change the topics, nothing else.
- CRITICAL: There is only ONE speaker. Use ONLY: {{ speaker_names[0] }}. Do NOT invent additional speakers.

- Avoid long monologues; keep exchanges between speakers balanced.

- Choose speakers strategically based on who would naturally contribute to each topic.

{% endif %}
{% if language %}
CRITICAL LANGUAGE REQUIREMENT:
- Write ALL dialogue lines exclusively in {{ language }}.
- Do NOT use English or any other language, not even for technical terms or proper concepts where a {{ language }} wording exists.
- These instructions are written in English, but every spoken line you produce MUST be in {{ language }}.
{% endif %}
IMPORTANT OUTPUT FORMAT:
- If you use extended thinking with <think> tags, put ALL your reasoning inside <think></think> tags
- Put the final JSON output OUTSIDE and AFTER any <think> tags
- Do NOT wrap the JSON in ```json code blocks - return the raw JSON object only
- Example correct format:
<think>Let me plan the dialogue...</think>
{"transcript": [...]}
When you're ready, provide the transcript.
