SnipKey AGENTS.md

SnipKey AGENTS.md is an instructions file for Codex, OpenCode from jtvargas/SnipKey. It costs 7,751 tokens per session, scanned A, original, MIT.

Repository instructions for SnipKey, a native iOS app for saving and quickly accessing text, links, images, and PDFs through a custom keyboard. It explains the app targets, architecture, storage, sync, and development setup.

In plain words
What is it for?
It helps agents open and run the project in Xcode, understand its SwiftUI, SwiftData, MVVM, and CloudKit setup, and work with the app and keyboard targets.
Why use it?
It gives coding agents the project context they need before changing the main app or its keyboard extension. It also reduces mistakes involving shared app data, iCloud, and the required iOS versions.

Token cost

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.

Security

Grade A, and why

SnipKey AGENTS.md scanned grade A with 1 finding 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 4d 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.

Project Overview

SnipKey is a native iOS app (SwiftUI + SwiftData) that lets users create, organize, and quickly access text snippets, URLs, images, and PDFs via a custom keyboard extension.

Version 5.5 (main app), 5.0 (keyboard extension)
Bundle ID jrtv-projects.SnipKey
Min Deployment iOS 17.0 (base), iOS 26.0 in latest build configs
Architecture MVVM with SwiftData
Sync iCloud via CloudKit
Monetization Free app with optional tips via RevenueCat
Privacy No analytics, no tracking, no third-party data sharing

Targets:

  • SnipKey — Main iOS application
  • SnipKeyboard — Custom keyboard extension (jrtv-projects.SnipKey.SnipKeyboard)

Shared infrastructure:

  • App Group: group.snipkey (shared data between app and keyboard extension)
  • iCloud Container: iCloud.SnipKeyCloud

Build & Run

Xcode (recommended)

Open SnipKey.xcodeproj, select the SnipKey scheme, pick a simulator or device, and press Cmd + R.

Command line

# Build the main app (debug)
xcodebuild -project SnipKey.xcodeproj -scheme SnipKey -configuration Debug build

# Build for a specific simulator
xcodebuild -project SnipKey.xcodeproj -scheme SnipKey \
  -destination 'platform=iOS Simulator,name=iPhone 16' build

# Clean build
xcodebuild -project SnipKey.xcodeproj -scheme SnipKey clean build

After building

The keyboard extension must be enabled manually:

  1. Go to Settings > General > Keyboard > Keyboards > Add New Keyboard
  2. Select SnipKey
  3. (Optional) Enable Allow Full Access for image/PDF clipboard operations

Testing

No tests currently exist. Test targets (SnipKeyTests, SnipKeyUITests) are defined in the Xcode scheme but contain no test files. Adding tests is a welcome contribution.

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.
