Its own cleanup-playbook.md uses the real `b2 rm -r --dry-run` flow (no invented flags); a naive baseline answer to the same cleanup request hallucinated a non-existent `--older-than` flag and skipped the dry-run entirely. Needs the b2 CLI pre-installed and manually authorized (`b2 account authorize`, interactive-only) before the skill can do anything real.

What B2 Cloud Storage does
Wraps the b2 CLI to list files, run a bundled storage-audit script (stale files, duplicates, unfinished uploads, estimated monthly cost), and manage lifecycle/security review for B2 buckets. Triggers on B2, Backblaze, object storage buckets, or storage cleanup requests. Hard security rules block reading credential files and require an explicit dry-run plus typed 'yes' before any deletion.

Commands — how to trigger B2 Cloud Storage
-
/b2-cloud-storageAudits, costs out, and safely cleans up Backblaze B2 buckets with mandatory dry-runs.

Our B2 bucket costs are creeping up, can you audit storage costs? -
Review my Backblaze bucket's security posture for public exposure. -
Check this B2 bucket for stale files and duplicates before cleanup.
Frequently asked questions
- Is the B2 Cloud Storage skill free?
- Yes. The skill itself is free from backblaze-labs/claude-skill-b2-cloud-storage. SkillProof publishes the install command and an independent test verdict at no cost.
- Does B2 Cloud Storage work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 14, 2026. Verdict: Works with setup. Its own cleanup-playbook.md uses the real `b2 rm -r --dry-run` flow (no invented flags); a naive baseline answer to the same cleanup request hallucinated a non-existent `--older-than` flag and skipped the dry-run entirely. Needs the b2 CLI pre-installed and manually authorized (`b2 account authorize`, interactive-only) before the skill can do anything real.
- What is the B2 Cloud Storage SkillProof Score?
- 9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.
- How do I install B2 Cloud Storage?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use B2 Cloud Storage with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
