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 | $0.00016 | $0.00396 |
| Opus 5 | $0.00008 | $0.00198 |
| Sonnet 5 | $0.00003 | $0.00079 |
| Haiku 4.5 | $0.00002 | $0.00040 |
Grade A, and why
animation-jank-qa 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 6d 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
Animation Jank QA
Use this skill for symptom-led runtime diagnosis. Start from a reproducible jank case and determine whether it comes from main-thread work, layout/paint, asset pressure, scroll coupling, competing animation systems, or lifecycle cleanup.
Workflow
- Reproduce the exact affected route, interaction, viewport, and device class.
- Read Animation Jank QA Guide for relevant diagnosis and retesting steps.
- Run the narrowest meaningful trace or rendered check for the symptom; inspect frame timing, long tasks, forced layout, paint/compositing, asset decode, observers, timers, and RAF loops as applicable.
- Fix issues when they are in scope; otherwise record exact evidence and remaining risk.
- Retest the original symptom and summarize commands, URLs, traces/screenshots, changed files, and what was not tested.
Always Protect
- Inspect the framework, motion stack, affected media, component lifecycle, and available browser/performance tooling before changing code.
- Do not claim something was tested unless it was actually tested; report exact commands, URLs, screenshots, viewports, failures, skipped checks, and remaining risk.
- Reproduce and retest rendered output on the affected route and supported viewport/device classes; inspect console, trace, network and layout evidence relevant to that symptom.
- Respect accessibility, performance, reduced-motion, and no-JavaScript/no-WebGL/no-autoplay fallbacks where relevant.
- Keep secrets out of code, logs, screenshots, summaries, widgets, and committed files.
- Prefer project-local tooling and existing scripts before adding dependencies. Explain any new dependency before installing it.
- End with a concise handoff: changed files, commands run, checks passed, checks not run, deployment URL if any, and next risks.
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.

animation-jank-qa is a skill published in the GitHub repository TheGoat395/Codex-Skills (123 stars, last pushed yesterday), licensed MIT. It adds 16 tokens to every session and 396 once invoked, about $0.0001 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.
