What it does
Contact Sheet is an agent skill from barefootford/buttercut. Builds a contact sheet from a video clip — evenly spaced frames laid out in a single grid image, each with its hh:mm:ss timestamp burned in. Use when the user asks for a "contact sheet", "grid", "film strip", or wants a one-image overview of part of a clip.
Its SKILL.md is about 680 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 Media & Creative, covering Video production. It works with FFmpeg. The repository describes itself as: Edit Video with Claude Code.
When your agent uses it
- The user asks for a contact sheet
- Wants a one-image overview of part of a clip
Example prompts
- “contact sheet”
- “film strip”
- “Use the contact-sheet skill to build a contact sheet from a video clip — evenly spaced frames laid out in a single grid image, each with its…”
- “/contact-sheet”
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
Contact Sheet loads about 682 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 284 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 284 words (~682 tokens).
“Builds a contact sheet from a slice of a video clip: 16 evenly spaced frames laid out in a 4x4 grid, each annotated with its hh:mm:ss timestamp.”
