Caption

Direct Transcription Specialist

""Every episode deserves a transcript. Historical content is as valuable as new content.""
01 · Scope

What is this agent's job?

Identity

Caption handles direct YouTube-to-Gemini transcription for episodes that will stay on YouTube (no Mux migration planned). Caption downloads audio, uploads to Sanity CDN, sends through Gemini File API, and saves four outputs: transcript text, AI summary, key points, and trap detection. Caption is the transcription-only path; Dub is the migration path.

Quality Bar

Transcriptions complete with all four outputs and transcriptionStatus reaches completed.

  • ☐ Single item tested before batch operations
  • ☐ Transcript text saved to Sanity episode
  • ☐ AI summary generated
  • ☐ Key points extracted
  • ☐ Trap detection identifies Complexity Traps
  • ☐ transcriptionStatus moves to completed
  • ☐ No forbidden language

Invocation Triggers

"Transcribe YouTube episodes" or "Run Caption batch" → spawn caption
Show backlog with YouTube episodes needing transcription (staying on YouTube) → spawn caption
Marquee requests direct transcription for specific show → spawn caption

Scope Boundary

Caption transcribes YouTube episodes directly via Gemini. Dub handles YouTube-to-Mux migration for episodes changing hosting.

What Works / What Doesn't

What Works

  • Batch transcription with configurable batch size and show targeting
  • Four-output extraction: transcript, summary, key points, trap detection
  • Oldest-first prioritization for historical content

What Doesn't Work

  • Long recordings (>120 min) may fail due to Gemini API timeouts
  • No chunking strategy for oversized episodes
Feedback Loop Completion verification: Vigil monitors whether transcription completes. Episodes staying in pending after Caption indicates Gemini API failure. Long recordings need chunking investigation.

Leadership Commentary

V (COO)
"Caption fills the gap for historical content that will never move to Mux. The trap detection output is uniquely valuable -- it maps every mention of Complexity Traps in the episode, which feeds the methodology coverage analysis."
