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 | $0.00073 | $0.01137 |
| Opus 5 | $0.00036 | $0.00568 |
| Sonnet 5 | $0.00015 | $0.00227 |
| Haiku 4.5 | $0.00007 | $0.00114 |
Grade A, and why
swiftui-animation-match 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SwiftUI Animation Match
Use this skill to turn a vaguely felt interaction wish ("saving should feel more satisfying", "this list is boring while it loads") into a concrete, proven SwiftUI animation pattern — or into the deliberate decision to use what the system already provides.
The skill is a matcher, not a snippet dump. Its value is the judgment step: name the interaction moment first, check what the OS gives you for free, and only then reach into the cataloged sources for custom motion that earns its place. Animations add juice that makes a product feel human; forcing one where the platform already shines makes it feel worse.
First move
- Name the moment. Translate the request into: what is the user doing, what should they feel, and how often does this happen? Read references/matching-playbook.md — it has the moment taxonomy and the system-first checklist.
- Decide system vs custom. If a system affordance covers the moment
(Liquid Glass chrome,
.symbolEffect, springs,.contentTransition, zoom navigation transitions,.sensoryFeedback), prefer it and stop. - If custom motion earns its place, search the catalogs (below) by interaction pattern and keywords, not by animation name.
- Adapt, never paste. Every catalog entry has lift notes and each catalog ends with a lift checklist (dependencies to replace, old patterns to modernize, Reduce Motion).
- Verify in motion. Build and watch it in Previews or Simulator; motion
cannot be judged from code. If the app repo has build/test skills
(for example
bootstrap-ios), use them.
Catalogs
Load only the catalog you need; entries are grouped by interaction moment and carry keywords, exact source paths, technique summaries, and lift notes.
| Catalog | Contents |
|---|---|
| catalog-shubham0812-swiftui-animations.md | 30 SwiftUI animations + 7 Metal shaders: loaders, progress, action feedback, toggles, card decks, text heroes, input chrome, reveals, shader effects |
What ships with it
4 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.

swiftui-animation-match is a skill published in the GitHub repository RayFernando1337/rayfernando-skills (129 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 73 tokens to every session and 1,137 once invoked, about $0.0004 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.
