after-effects

after-effects is a skill for Claude Code from 2233admin/design-pipeline. It costs 242 tokens per session (1,822 once invoked), scanned A, a copy of after-effects, MIT.

A reference for Adobe After Effects, a desktop app for creating and compositing animated graphics and video. It provides expressions, rigging setups, export guidance, performance troubleshooting, and project-organisation advice.

In plain words
What is it for?
Use it to write expressions, build reusable motion templates, export to formats such as Lottie, fix preview or render problems, organise footage, and automate projects with scripts.
Why use it?
It helps solve common After Effects tasks such as controlling animation with JavaScript-like expressions, exporting with the right settings, and diagnosing slow or failing projects.

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

after-effects 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 5d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

After Effects

After Effects is GUI software, so this skill delivers knowledge and ready-to-paste assets — expressions, rig setups, export checklists, diagnostic flows, naming schemes, and ExtendScript — rather than a rendered file. It is a hub covering four domains; route to the matching reference for depth and complete recipes.

Routing

If the user wants to… Go to
Write/debug an expression, rig sliders & nulls, build a MOGRT, export to Lottie references/expressions.md (deep cookbook in references/expression-library.md)
Choose a codec/container, export with alpha, fix a black background, set bitrate, recover H.264 references/export-recipes.md
Fix slow/laggy previews, slow renders, crashes, freezes, out-of-memory references/performance-triage.md
Organize the project, relink missing footage, set naming/folders, batch-automate with .jsx references/project-hygiene.md

The .jsx automation scripts live in scripts/.

Expressions & rigging

Expressions are JavaScript evaluated on the property they are pasted on; value is that property's value, time is comp time in seconds, and index, thisLayer, thisComp are in scope. An expression overrides keyframes unless it incorporates value.

wiggle(2, 30);            // 2 wiggles/sec, amplitude 30 (property units)
loopOut("cycle");         // repeat keyframed range forever; "pingpong" / "offset" / "continue"
seedRandom(index, true);  // stable-but-unique per layer (timeless) before random()/wiggle()
thisComp.layer("Lead").transform.position.valueAtTime(time - 0.2 * index);  // staggered echo

Inertial bounce (overshoot/settle after the last keyframe) and the full loop/wiggle/rigging set are in references/expressions.md.

Rig controllable motion: add a null with Slider / Checkbox / Color / Angle / Point control effects, then reference them and parent transforms to drive many layers from one.

ctrl = thisComp.layer("Controls");
amt  = ctrl.effect("Intensity")("Slider");   // Checkbox → 1/0, Color → [r,g,b,a]
value * amt;

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.
