splicedeck: Skill for Claude Code

.claude/skills/cutting-vertical-clips/SKILL.md

cutting-vertical-clips is a skill for Claude Code from ihuzaifashoukat/splicedeck. It costs 97 tokens per session (1,053 once invoked), scanned A, original, Apache-2.0.

A workflow for cutting a vertical video clip from a finished master video while keeping the subject in frame. It uses the same analysis as the master and prepares the clip for a 9:16 phone-shaped export.

In plain words
What is it for?
Use it to make vertical clips, such as 1080×1920 videos for phones, when a subject moves around the frame.
Why use it?
It avoids reanalysing the source and provides a defined sequence for choosing a time span, reframing it, adding captions, checking it, and delivering it.

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

cutting-vertical-clips 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cutting vertical clips

A vertical deliverable is cut from the same analysis as the master, not from a second pass. The whole design is one analysis per source shared by every deliverable, so a run producing a master and three clips spawns no more children than one producing the master alone.

Framing is owned by docs/framing.md. This file is the path through the verbs.

The order

(a finished master sheet)  →  carve  →  watch  →  caption  →  verify  →  deliver
  • carve --sheet c1 --profile tall-1080 --in_ticks 0 --out_ticks 2700000 writes a second sheet from the first: body and caption entries clipped and re-based onto a timeline starting at tick 0, plus a frame lane. It spawns no child process.
  • watch --source s1 --subject centre --out_shape 9:16 derives the framing path. The result is cached by source, subject and shape, so a second watch with the same three spawns nothing.
  • Everything after that is the ordinary chain.

Which span becomes a clip is a human decision. carve takes the span from the caller and splicedeck does not score or rank candidates — that exclusion is deliberate (docs/roadmap.md, Not in v1). Ask, or use a span the person named.

Subject tiers, and which one actually works

--subject takes largest, centre or none.

Tier Needs State
centre nothing works in a fresh clone
largest the reduce locator, or model weights reduce tier works; model tier has no acquisition path
none nothing no tracking, static window

SUBJECT_MODEL_ABSENT does not mean vertical is impossible. It means the model tier is unavailable. SPD_SIGHT_LOCATOR selects the locator, and the geometric reduce tier needs no weights at all. Start with --subject centre when you just need a vertical export; reach for tracking when the subject actually moves.

The refusals particular to this path

Code Means Do this
NEEDS_FRAMING the sheet has no frame lane for this canvas run watch for that shape; the refusal carries the call
SOURCE_TOO_NARROW filling 9:16 would upscale past the ceiling report the scale factor in plain; a wider source is the only fix
WINDOW_ASPECT a framing entry fails the exact integer cross-product against the canvas a bug in whatever wrote the path, not a caller error
LEGIBILITY_FAIL caption text falls under the contrast or size floor at this width vertical is the narrowest canvas, so this bites here first
SAFE_AREA_FAIL an element lands where a platform's own interface sits move it; the profile declares the insets
WORD_TOO_WIDE a single word cannot fit the line box shorter caption text, or a smaller style

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.
