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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00036 | $0.01037 |
| Opus 5 | $0.00018 | $0.00518 |
| Sonnet 5 | $0.00007 | $0.00207 |
| Haiku 4.5 | $0.00004 | $0.00104 |
Grade A, and why
media 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.
Media
Networking Clarification
Media playback URLs are permitted. The forbidden-patterns networking ban targets REST API clients (URLSession data tasks, custom HTTP clients), not media playback. The following are allowed:
AVPlayerwith remote URLs (MP4, HLS.m3u8streams)AsyncImageloading remote image URLsKFImage(Kingfisher) loading and caching remote imagesURLSession.shared.download(from:)only for downloading media files to local storage
Do not use URLSession for REST API calls, JSON fetching, or custom networking — that ban still applies.
Decision Tree
Pick the right pattern based on what you're building:
| Building | Reference | Key API |
|---|---|---|
| Video player | video-playback | VideoPlayer, AVPlayer |
| HLS/live streaming | video-playback | AVPlayer + .m3u8 URL |
| Video feed (TikTok-style) | video-playback + media-memory-management | FeedPlayerCoordinator |
| Music/audio player | audio-playback + audio-session | AVAudioPlayer (local) or AVPlayer (streaming) |
| Podcast player | audio-playback + audio-session | AVPlayer + Now Playing + Remote Commands |
| Background audio | audio-session | .playback category + UIBackgroundModes |
| Image gallery/feed | remote-images | KFImage (Kingfisher) |
| Simple remote image | remote-images | AsyncImage |
| Sound effects | audio-playback | AVAudioPlayer with .ambient category |
| Sample content | sample-media-urls | Public URLs, local audio generation |
Platform Capabilities

What ships with it
6 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.
- 5d ago First seen · 85 lines · 36 tokens per session scan A 2408bec0640d
media is a skill published in the GitHub repository Abdullah4AI/apple-developer-toolkit (10 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 1,037 once invoked, about $0.0002 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 2026-09-03.
