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 | $0.01502 | $0.01502 |
| Opus 5 | $0.00751 | $0.00751 |
| Sonnet 5 | $0.00300 | $0.00300 |
| Haiku 4.5 | $0.00150 | $0.00150 |
Grade A, and why
Bark CLAUDE.md 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 3d 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.

Project Overview
Bark is an iOS push notification tool app that allows users to send custom push notifications to their devices via HTTP requests. It leverages Apple Push Notification service (APNs) and supports advanced iOS notification features like grouping, custom icons/sounds, time-sensitive notifications, critical alerts, and end-to-end encryption.
Development Commands
Dependencies
# Install CocoaPods dependencies
pod install
# Always work with the workspace, not the project
# Open: Bark.xcworkspace
Testing
# Run tests via fastlane
bundle exec fastlane tests
# Run tests via xcodebuild
xcodebuild test -workspace Bark.xcworkspace -scheme Bark
Building
# Build the app
xcodebuild -workspace Bark.xcworkspace -scheme Bark build
# Build for TestFlight (requires proper certificates and environment variables)
bundle exec fastlane beta
Architecture
Core Components
Main App Target (Bark/)
- Entry point:
AppDelegate.swift- handles app lifecycle, APNs registration, Realm setup AppDelegate+Realm.swift- Realm database initialization and migration logic- Realm schema version: 17 (see
RealmConfiguration.swift)
Notification Extensions
NotificationServiceExtension/- UNNotificationServiceExtension that processes incoming notificationsNotificationService.swift- orchestrates notification processing through a pipeline of processorsProcessor/directory contains specialized processors that run sequentially:CiphertextProcessor- decrypts encrypted push content (must run first)MarkdownProcessor- renders markdown in notification bodyLevelProcessor- handles notification levels (active/timeSensitive/passive/critical)BadgeProcessor- manages app badge countAutoCopyProcessor- auto-copies content to clipboardArchiveProcessor- saves message to Realm databaseMuteProcessor- handles group mutingCallProcessor- plays repeating sound for 30 secondsImageProcessor- downloads and attaches imagesIconProcessor- sets custom notification icon (iOS 15+, runs last as it may timeout)
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.

Bark CLAUDE.md is an instructions file published in the GitHub repository Finb/Bark (8,970 stars, last pushed 15d ago), licensed MIT. It adds 1,502 tokens to every session, about $0.0075 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.
