edit

A command for making one focused change to an existing video file. It supports operations such as cutting, joining, adding subtitles or music, changing speed, reframing, and removing pauses.

In plain words
What is it for?
Use it for quick video cleanup or format changes after checking details such as duration, dimensions, and whether the source has audio.
Why use it?
It keeps a small edit to one deliberate operation and saves the result as a new file, protecting the original.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Or install promptcut, the plugin that ships this one along with the rest of its 3 skills, 8 commands.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

edit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Use the video-toolbox skill in single-action mode. Task: $ARGUMENTS

probe the input first when the answer depends on its length, size or whether it has audio. Pick the one command that does the job, write the result to a new file next to the source (never overwrite their original), and report the path plus what changed. Chain commands only when the request genuinely needs it.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
