Stream processing, large file uploads, and IO efficiency. Use when: file processing.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# file-processing Skill

## Goal
This skill guides the handling of binary data and large datasets without blowing up RAM.

## Steps
## 1. Streaming (Chunks)
- **Problem**: Reading 1GB CSV into memory (RAM).
- **Solution**: Stream it line by line.
  - nodejs: `fs.createReadStream().pipe(csvParser())`.
  - python: `pd.read_csv(chunksize=1000)`.

## 2. Uploads (Presigned URLs)
- **Anti-Pattern**: Client -> Server (RAM buffer) -> S3.
- **Pattern**: Client -> (Request URL) -> Server; Server -> (Signed URL) -> Client; Client -> (Direct Upload) -> S3.
- **Benefit**: Server CPU/RAM is zero during upload. Infinite scalability.

## 3. Malware Scanning
- Never trust user files.
- **Sync**: ClamAV scan on upload (slow).
- **Async**: Upload to S3 (Quarantine Bucket) -> Lambda triggers Scan -> Move to Clean Bucket.

## 4. Exporting Large Data
- Don't return 100k rows in JSON response (timeout).
- **Pattern**:
  1. User requests Export.
  2. Server puts job in Queue.
  3. Worker generates CSV, uploads to S3.
  4. Server notifies User with Download Link.

## 5. File Types
- **Magic Bytes**: Check file signature (hex), not just extension.

How to install

The exact contents, by fingerprint

mdr add andreibesleaga/gabbe/file-processing@sha256:3da5d12ac3265e3f

The line at the top of this page pins the label git:20261014.de0823c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
