Safely plan and execute Backblaze B2 S3-compatible storage operations and B2 native bucket, key, and notification administration.
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
# Backblaze B2 storage
`scripts/backblaze.py` is a standalone JSON CLI. It deliberately contains its
own package under `scripts/lib/ls_backblaze`: an installed optional skill must
not depend on a LocalSetup checkout, LocalSetup wheel, or another skill.
Use `--tool`, and exactly one of `--args-json` or `--args-file` (`-` reads
stdin). Without `--apply`, every valid request returns a zero-network plan.
`--schema` and `--capabilities` are also offline. Requests never contain raw
credentials; apply-mode configuration refers to credentials by `{ "env":
"NAME" }` or `{ "file": "/protected/path" }`.
```bash
python3 scripts/backblaze.py --tool s3.ListObjectsV2 \
--args-json '{"bucket":"example","prefix":"reports/"}'
python3 scripts/backblaze.py --tool native.ListBuckets --args-json '{}' \
--config b2-config.json --apply
```
Install the caller-owned SDK environment from `requirements-s3-sdk.txt`; the
tool never installs packages. S3 credentials are explicit and SDK discovery,
metadata lookup, and shell credential processes are disabled. Native requests
require HTTPS, validate official B2 endpoints, do not follow redirects, and
…Read the whole file at its exact version.
How to install
mdr add cruxexperts/localsetup/ls-backblaze-b2-storage@sha256:568d3f5c6b84079fThe line at the top of this page pins the label v1.1, 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.
