Steps

Step 1: Search Files

1.1 Find SRT files

If --srt provided, use that file directly.

Otherwise, search for corrected SRT files:

ls 2-echo-delta/videos/subtitles/corrected/*_corrected.srt

1.2 Find Video files

For each SRT, infer matching video:

# From: meetup_02_건호님_corrected.srt
# Extract: meetup_02_건호님

srt_name = "meetup_02_건호님_corrected.srt"
video_stem = srt_name.replace("_corrected.srt", "")  # meetup_02_건호님

# Search order:
# 1st: cropped/{video_stem}_cropped.mov
# 2nd: raw/{video_stem}.mov

ls 2-echo-delta/videos/cropped/
ls 2-echo-delta/videos/raw/

Step 2: Confirm Selection (AskUserQuestion)

IMPORTANT: Always confirm with user before proceeding.

Show found files and ask for confirmation:

Task: AskUserQuestion
Question: "Proceed with these files for finalize?"

Display:
  SRT file: subtitles/corrected/meetup_02_건호님_corrected.srt
  Video file: cropped/meetup_02_건호님_cropped.mov

  Output will be:
  - English subtitle: subtitles/en/meetup_02_건호님_corrected_en.srt
  - Burn-in video: burnin_output/meetup_02_건호님_cropped_burnin.mp4

Options:
  - Proceed
  - Select different SRT
  - Cancel

If user selects "Select different SRT":

• Show list of available SRT files from corrected/
• Let user choose
• Re-match video file
• Confirm again

Step 3: Parallel Execution

Run both agents simultaneously in a single message:

Task A: video-subtitle:subtitle-translator
Prompt: |
  Translate the following Korean subtitle to English.
  - srt_path: {srt_path}

Task B: video-subtitle:subtitle-burnin
Prompt: |
  Burn subtitles into video.
  - video_path: {video_path}
  - srt_path: {srt_path}

IMPORTANT: Call both Tasks in parallel in the same message.

Step 4: Report Results

After both complete, summarize:
