byted-tos-file-processCompresses 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…

Compress and uncompress file objects stored in Volcengine TOS through the TOS gateway's file_jobs API.
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>
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 |
# 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
| 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. |
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.zip, tar, and zst. The output object key suffix must match the chosen format (.zip, .tar, .zst).--wait flag.
