When your agent uses it
- User wants to check for updates
- Update their installation for new features
Example prompts
- “/update-buttercut”
Requirements
- Python 3
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:
gitrubybundlepip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git and pip, which can reach the network depending on how they are called.
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
Update Buttercut loads about 1.7k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 1,016 words of instructions outside code blocks.
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 1,016 words (~1,688 tokens).
“Updates ButterCut to the latest version, then recaps what's new in plain video-editor language. Users of this project are video editors — Claude sometimes edits code on its own and may even leave the repo on a side branch. The…”
