What it does

Backup Library is an agent skill from barefootford/buttercut. Backs up user libraries and all their contents (external video excluded). This skill can also be useful when you need to restore a library.

Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Backup and disaster recovery. The repository describes itself as: Edit Video with Claude Code.

When your agent uses it

  • Tasks that involve Backup and disaster recovery

Example prompts

  • “Use the backup-library skill to back up user libraries and all their contents (external video excluded)”
  • “/backup-library”

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Resolve the destination
  2. Run the backup

What it can do on your machine

Read from SKILL.md and the folder at commit 352c1e0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • ruby

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Backup Library loads about 790 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 279 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~790

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 279 words (~790 tokens).

“Backups default to ~/Documents/buttercut-video-editor-backups. Each library gets its own subdirectory there, and each run drops a timestamped archive of just that one library — so adding a new clip to one library only writes that library's archive, not a full…”
