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 →

Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 | $0.00217 | $0.04250 |
| Opus 5 | $0.00109 | $0.02125 |
| Sonnet 5 | $0.00043 | $0.00850 |
| Haiku 4.5 | $0.00022 | $0.00425 |
Grade A, and why
photokit 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 9d 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 — 292 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PhotoKit & AVFoundation Capture (iOS)
Photo-library picking, library access, and custom camera capture for a fintech iOS app (document/ID capture, receipt attachments, avatars). Grounded in Apple's PhotosUI, Photos (PhotoKit), and AVFoundation frameworks; targets the iOS 26 era.
- Decision: need a plain image/video pick with no library permission? Use
PhotosPicker(SwiftUI) orPHPickerViewController(UIKit) — both run out of process and hand back only chosen items. Need to enumerate/organize the library, observe changes, or fetch by metadata? That requiresPHPhotoLibraryauthorization and PhotoKit. Need live camera (KYC selfie, ID/cheque scan)? Use AVFoundation. - Cross-refs: OCR / barcode / MRZ / document rectangle detection on a captured frame →
vision-framework; on-device image models →coreml; permission strings & privacy manifest for submission →app-store-review; if a KMPcommonMainscreen needs the picker, expose anexpectcapture interface bound to aniosMainactual→expect-actual.
Contents
- Privacy strings (required)
- PhotosPicker (SwiftUI)
- PHPickerViewController (UIKit)
- Library authorization & limited access
- Fetching assets (PHAsset)
- Requesting images (PHImageManager)
- Writing to the library (change requests)
- Custom camera capture (AVFoundation)
- Fintech guidance
- Correctness checklist

Missing a required key = hard crash the moment the API is touched. Add to Info.plist:
| Key | When needed |
|---|---|
NSPhotoLibraryUsageDescription |
Read/write library access (.readWrite), PHAsset fetches, PHImageManager. |
NSPhotoLibraryAddUsageDescription |
Add-only access (.addOnly) — saving without ever reading. Prefer this when you only save. |
NSCameraUsageDescription |
Any AVCaptureSession with a camera input; also PHPickerViewController/PhotosPicker do not need it. |
NSMicrophoneUsageDescription |
Video capture with audio (adding an audio AVCaptureDeviceInput). |
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.

photokit is a skill published in the GitHub repository TalissonVitorino/kmp-ios-skills (12 stars, last pushed 18d ago), licensed MIT. It adds 217 tokens to every session and 4,250 once invoked, about $0.0011 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.
Other skills, from other repositories
compose-multiplatform
Use when building one shared Compose UI in Kotlin across Android, iOS, and desktop — commonMain @Composables, expect/actual, source-set placement, native interop, multiplatform ViewModel/navigation/Koin. NOT a single-platform native build (that is kotlin-android / swift-ios), and NOT Dart/Flutter cross-platform UI…
cmp-new
Scaffold a new MOBILE app — Android + iOS from one Kotlin/Compose Multiplatform codebase — from a bare "create a mobile app" to a green, verified build. Guardrails first: if the user already chose a different framework (React Native, Expo, Flutter, SwiftUI, native), do NOT redirect them here; if they only asked a…
cmp-firebase-connect
Wire a freshly scaffolded CMP/KMP app to its OWN real Firebase project — the #1 post-scaffold manual step. Use this when the user wants to connect their app to Firebase, or asks "connect my app to firebase", "set up google-services.json", "wire firebase", "create a firebase project for this app", "replace the…
add-feature
Add a new conforming vertical-slice feature (Screen + ViewModel + UseCase + Repository + spec + tests + golden tree + nav route + DI wiring) to this Compose Multiplatform app, cloned deterministically from the project's configured exemplar feature (qa/approvals.json's exemplarFeature — home by default). Use this when…
cmp-audit
Adversarial audit of one subsystem of a Kotlin/Compose Multiplatform app against its spec AND against platform semantics — the class of defect desktop-tier tests cannot see (alarms, notifications, PendingIntents, reboot, process death, DST). Use this when the user says "audit the notifications", "double check X for…
