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.

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 | $0.00084 | $0.01164 |
| Opus 5.5 | $0.00034 | $0.00466 |
| Sonnet 5.5 | $0.00017 | $0.00233 |
| Haiku 4.5 | $0.00008 | $0.00116 |
Grade A, and why
ios-animation-code-review 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 1mo 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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS Animation Code Review
Quick Reference
| Issue Type | Reference |
|---|---|
| Spring parameters, withAnimation misuse, phase/keyframe bugs | references/swiftui-animation-patterns.md |
| Frame drops, offscreen rendering, main thread blocking | references/performance.md |
| Reduce Motion, VoiceOver, motion sensitivity | references/accessibility.md |
| Transition protocol, matchedGeometryEffect, navigation transitions | references/transitions.md |
Hard gates (sequence)
Complete in order for the files in scope. If a step fails, omit the finding, re-anchor, or downgrade to a question—do not ship accusations without meeting the pass condition.
| Step | What you do | Pass condition (objective) |
|---|---|---|
| 1. Inventory | List each file under review and where animation APIs appear (line ranges or symbol names: withAnimation, .animation, matchedGeometryEffect, PhaseAnimator, UIKit/CA animators, etc.). |
A written list exists; files with no animation APIs are explicitly marked out of scope. |
| 2. Anchor | Re-read the cited region in the current file or diff hunk before naming an issue. | Each [FILE:LINE] still shows the behavior; stale line numbers are fixed or the finding is dropped. |
| 3. Evidence | For framework-specific claims (spring curves, Transition conformance, Reduce Motion), cross-check the matching row in Quick Reference against references/*.md. |
The finding’s detail names the reference file used, or states inline-only (structural/readability with no framework rule). |
| 4. Report | Emit findings using Output Format. | Headers match [FILE:LINE] ISSUE_TITLE; checklist items below are applied only where gates 1–2 covered that code. |
Output Format
Report each finding as:
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.

ios-animation-code-review is a skill published in the GitHub repository existential-birds/beagle (82 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 84 tokens to every session and 1,164 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-16.
