Byted Tos File Process

Compresses and uncompresses file objects stored in Volcengine TOS through TOS data-process async jobs. Use this skill when the user needs to zip files, unzip archives, create tar or zstd archives, extract compressed files, pack multiple TOS objects into a single archive, bundle files together, or distribute files as a package — even if they don't explicitly mention 'compression', 'archive', '打包', or '压缩'.

File contents

Volcengine TOS File Process

Compress and uncompress file objects stored in Volcengine TOS through the TOS gateway's file_jobs API.

Setup (once per environment)

Install dependencies on first use:

cd {baseDir}
pip install -r {baseDir}/requirements.txt

Then run scripts with Python 3.7+:

python3 {baseDir}/scripts/<script>.py <args>

Environment Variables

This skill relies on the TOS identity declared in the metadata block. Common runtime variables are:

Environment Variable	Required	Description
`TOS_ACCESS_KEY`	Yes	TOS access key ID
`TOS_SECRET_KEY`	Yes	TOS secret access key
`TOS_ENDPOINT`	Yes	TOS endpoint URL
`TOS_REGION`	Yes	TOS region
`TOS_BUCKET`	Yes	Source bucket that stores the file objects
`TOS_OBJECT_KEY`	No	Source object key. Can be overridden with `--key` or `--keys`
`TOS_SECURITY_TOKEN`	No	STS session token when using temporary credentials

Quick start

# Compress multiple TOS objects into a zip archive and wait for completion
python3 {baseDir}/scripts/file_compress.py \
  --keys file1.jpg,file2.txt \
  --format zip \
  --output-key output/archive.zip \
  --wait

# Uncompress a zip archive and wait for completion
python3 {baseDir}/scripts/file_uncompress.py \
  --key output/archive.zip \
  --prefix output/unzipped/ \
  --wait

Available scripts

Script	Purpose
`scripts/file_compress.py`	Submit an async `FileCompress` job via the TOS gateway's `file_jobs` API that compresses TOS objects into an archive (zip/tar/zst). Supports `--wait` to poll until completion.
`scripts/file_uncompress.py`	Submit an async `FileUncompress` job via the TOS gateway's `file_jobs` API that extracts an archive in TOS. Supports `--wait` to poll until completion.
`scripts/tos_jobs_client.py`	Shared client for TOS gateway `file_jobs` APIs using pre-signed URL auth.

Rules

TOS gateway API: This skill uses the TOS gateway's file_jobs API with job_type=FileCompress or job_type=FileUncompress. Authentication is handled via pre_signed_url from the TOS Python SDK and the TOS identity declared in the metadata block above.
Supported archive formats: Compress supports zip, tar, and zst. The output object key suffix must match the chosen format (.zip, .tar, .zst).
Async job model: The scripts create async jobs and optionally wait for completion with the --wait flag.
Language: Reply in the user's preferred language.
