A command for turning a topic, script, or longer video into short vertical videos for platforms built around reels and other phone-sized clips.

Use it to create 25–55 second vertical videos, select highlights from a transcript, add large subtitles and music, and export one file per short.

It reduces the manual work of finding usable moments, reframing footage, adding subtitles, and assembling a short edit.

Per session 18 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 177 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00018	$0.00177
Opus 5.5	$0.00007	$0.00071
Sonnet 5.5	$0.00004	$0.00035
Haiku 4.5	$0.00002	$0.00018

Security

Grade A, and why

shorts 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 2mo 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. Target: $ARGUMENTS

Vertical defaults: aspect 9:16, subtitles.max_chars 26, big bold subtitles, 6-10 shots of 8-14 words, music bed at -23 dB, total 25-55 seconds.

If the input is an existing video file: transcribe --granularity word, pick the strongest self-contained stretches from the transcript, cut each one, reframe --aspect 9:16 --mode blur, then subs-burn. Report one file per short.

If the input is a topic or script: storyboard it into plan.json, build --fake to check the length, then build.

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.
