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.

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 | $0.00101 | $0.03292 |
| Opus 5 | $0.00051 | $0.01646 |
| Sonnet 5 | $0.00020 | $0.00658 |
| Haiku 4.5 | $0.00010 | $0.00329 |
Grade A, and why
shot-composition 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shot Composition
Stage the frame and move the camera: grid systems, safe areas, focal hierarchy, negative space, parallax layering, and how layout guides the eye over time. Produces composition notes, layer structure (bg/mid/fg), and concrete camera-move plans with numbers.
When to use
- Defining a frame's layout, focal point, and negative space.
- Planning element enter/exit directions and motion paths.
- Designing camera push/pull, pan, follow, and parallax moves.
- Adapting one composition across 16:9, 9:16, and 1:1 with safe areas.
Decision tree
What are you staging?
├─ A static frame's layout
│ └─ set grid → place ONE focal point on a thirds power point
│ → rank hierarchy (size>contrast>color>position) → reserve negative space
├─ Where things enter / leave
│ └─ follow reading direction; nearest edge; ease-out in, ease-in out
│ (new content → from right/below; back/undo → reverse it)
├─ A sense of depth / a camera move
│ └─ split into bg/mid/fg layers (the three motion layers)
│ → ONE camera move per beat (push | pan | follow | parallax), ease-in-out
└─ One comp across aspects (16:9 / 9:16 / 1:1)
└─ master in 16:9, focal in the center band → RESTACK (don't crop) for 9:16
→ keep critical content inside title-safe margins
Cross-reference — apply the shared frameworks. This skill is the spatial half of animation-principles. Apply them explicitly:
- 1/3 Rule (
animation-principles) has two forms and this skill uses both spatially: (a) Composition thirds — place the focal point on a rule-of-thirds power point (33%/67%); (b) Distance — no element travels more than ~1/3 of the frame without an intermediate keyframe or a scale/opacity change, so entrances stay readable. - Three motion layers (
animation-principles: Primary / Secondary / Ambient) map directly onto depth: foreground = Primary (the move the eye follows), midground = Secondary (the subject + supporting reactions), background = Ambient (slow, low-contrast life). Parallax speed scales with that role. - Settle the Three Pillars (Emotional intent / Visual narrative / Motion craft) and the chosen Motion Personality (
motion-art-direction) before numbering a camera move — premium wants slow long pushes, energetic wants whip-pans.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

shot-composition is a skill published in the GitHub repository iart-ai/motion-design-skills (28 stars, last pushed 2mo ago), licensed MIT. It adds 101 tokens to every session and 3,292 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
