Gastrohem Media Processor

Overview

Automatski procesira WhatsApp media fajlove (audio i slike) u Gastrohem dnevnim folderima.

Što radi:

• Transkribuje audio fajlove paralelno (3x brže) → kreira .json fajlove
• Identifikuje slike koje trebaju OCR → kreira .md fajlove sa prirodnim sažetkom
• Default: Koristi današnji datum automatski
• Skenira SVE odjele odjednom za dati datum

Performance:

• Audio: Do 3 fajla istovremeno (paralelno)
• Slike: Batch OCR (sve odjednom sa Claude vision)
• Scan: Nalazi sve foldere za datum u <1 sekundi

Note: Skill kreira .json za audio i .md za slike - dodavanje u chat.md je odvojen korak.

When to Use This Skill

User says:

• "Process media"
• "Process today's media"
• "Transcribe audio files"
• "Process media for 24.10"
• "OCR images in today's folders"

Default behavior: Uses today's date, scans all departments automatically.

Workflow

Simple Usage

Process all media for today (DEFAULT):

python .claude/skills/gastrohem-media-processor/scripts/process_media.py

• Uses today's date automatically (26.10 danas)
• Scans ALL departments for folders matching today's date
• Transcribes audio in parallel
• Lists images needing OCR

Process specific date:

python .claude/skills/gastrohem-media-processor/scripts/process_media.py --scan-date 24.10

Process specific folder:

python .claude/skills/gastrohem-media-processor/scripts/process_media.py --folder "gastrohem whatsapp/administracija/20.10 - 27.10/24.10"

What Happens

Audio Processing:

1. Finds all audio files (.mp3, .ogg, .m4a, .wav, .opus)
2. Skips files that already have .json transcriptions
3. Transcribes in parallel (3 concurrent processes)
4. Creates JSON: {audio_filename}.json

   {
     "speakers": [],
     "chunks": [...],
     "text": "Full transcribed text here"
   }
   

Image Processing:

1. Finds all images (.png, .jpg, .jpeg, .webp, .bmp)
2. Checks which images DON'T have .md files
3. Returns list of images needing OCR
4. Claude reads images in parallel and creates natural summaries with Gastrohem-relevant info
5. Creates markdown: {image_filename}.md

Script Reference

Three Separate Scripts

The skill now uses three modular scripts for better organization:

1. process_audio.py

Purpose: Audio transcription only (parallelized)

Usage:

python scripts/process_audio.py "path/to/folder" [--max-workers 3] [--output-json results.json]

Arguments:

• folder - Path to folder containing audio files
• --max-workers N - Max parallel processes (default: 3)
• --no-skip-existing - Re-transcribe files with existing JSON
• --output-json FILE - Save results to JSON

What it does:

• Finds audio files (.mp3, .ogg, .m4a, .wav, .opus)
• Skips files with existing .json transcriptions
• Transcribes in parallel (max 3 concurrent)
• Creates JSON files: {audio_filename}.json

Requirements: insanely-fast-whisper in PATH

2. process_images.py

Purpose: Image OCR helper functions

Usage:

# List images needing OCR
python scripts/process_images.py "path/to/folder" [--output-json images.json]

# Use in Python for batch processing
from process_images import save_ocr_md, batch_save_ocr, get_images_needing_ocr

Key functions:

• get_images_needing_ocr(folder_path) - Returns list of images without .md files
• save_ocr_md(image_file, summary, sender) - Save natural summary to .md file
• batch_save_ocr(ocr_results) - Save multiple OCR results at once

3. process_media.py

Purpose: Master script combining audio + images

Usage:

# Scan all folders for a specific date
python scripts/process_media.py --scan-date DD.MM [--output-json results.json]

# Process a specific folder
python scripts/process_media.py --folder "path/to/folder" [--output-json results.json]

Arguments:

• --scan-date DD.MM - Scan all departments for this date
• --folder PATH - Process specific folder
• --base-path PATH - Base path (default: gastrohem whatsapp)
• --no-skip-existing - Re-process all files
• --output-json FILE - Save results to JSON

What it does:

• Calls process_audio.py for audio files
• Calls process_images.py to find images needing OCR
• Returns combined results

Best Practices

1. Use --scan-date for daily processing - Automatically finds all folders for a specific date across all departments
2. Process audio in parallel - The script now handles up to 3 audio files simultaneously for faster processing
3. Batch OCR images - Read all images in parallel using Claude's vision for maximum efficiency
4. Save results to JSON - Use --output-json to keep a record of processing results
5. Process regularly - Process media files daily to avoid backlog
6. Separate chat.md updates - This skill creates JSON files; updating chat.md is a separate workflow

Error Handling

If transcription fails:

• Check that insanely-fast-whisper is installed
• Verify the audio file is not corrupted
• Check that the device (mps) is available
• Manually transcribe if necessary

If image OCR is unclear:

• Request higher quality image from sender
• Focus on extracting key information rather than perfect transcription
• Note any illegible portions in the context field

Example Workflows

User: "Process media"

Claude:

1. Runs: python .claude/skills/gastrohem-media-processor/scripts/process_media.py
2. Script uses today's date (26.10), scans all departments
3. Finds 3 folders: administracija/26.10, finansije/26.10, adis-chat/26.10
4. Transcribes 5 audio files in parallel → .json files created
5. Returns list of 3 images needing OCR
6. Claude reads all 3 images in parallel, creates natural summaries → .md files created
7. Reports: "Processed 5 audio and 3 images across 3 folders."

User: "Process media for 24.10"

Claude:

1. Runs: python .claude/skills/gastrohem-media-processor/scripts/process_media.py --scan-date 24.10
2. Same workflow for 24.10 date

Performance Improvements (Nove Optimizacije)

1. Paralelizacija Audio Transkripicja:

• Do 3 audio fajla se transkribuju istovremeno
• Koristi ThreadPoolExecutor za paralelno izvršavanje
• 3x brže nego prije

2. Batch OCR za Slike:

• Sve slike se mogu pročitati odjednom (parallel Read tool calls)
• Svaka slika dobija svoj .md fajl: image.png.md
• Prirodan sažetak sa fokusom na Gastrohem-relevantne informacije (kontakti, imena, brojevi, poslovni detalji)
• Helper funkcija save_ocr_md() za lako čuvanje

3. Automatski Scan Svih Foldera:

• Default: Koristi današnji datum (nije potrebno specificirati)
• Automatski pronalazi sve foldere za taj datum u SVIM odjelima
• Procesira sve odjednom

Struktura Skripti:

• process_audio.py - Audio only (paralelno)
• process_images.py - Image OCR helper functions
• process_media.py - Master skripta (kombinuje oba)

Tipična brzina:

• Audio: ~3-5 sec po fajlu (paralelno, 3 max)
• Slike: ~2-3 sec po slici (batch)
• Scan svih odjela: <1 sekunda
