What is OpenBoringBar AGENTS.md?

Repository-specific instructions for OpenBoringBar, an open-source macOS taskbar for multiple displays. They describe its goals, supported software, and folder layout for contributors and coding agents.

Use it when changing OpenBoringBar code, documentation, or scripts. It covers per-display bars, running-app visibility, app switching, macOS 14+, Swift 5, SwiftUI, AppKit, and project generation.

Agents working in an unfamiliar repository may otherwise miss its product priorities, platform requirements, or project structure. These instructions set the expected technical and product context.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01735	$0.01735
Opus 5.5	$0.00694	$0.00694
Sonnet 5.5	$0.00347	$0.00347
Haiku 4.5	$0.00173	$0.00173

Security

Grade A, and why

OpenBoringBar AGENTS.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 2mo 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.

OpenBoringBar Agent Guide

AI collaboration entry for OpenBoringBar. Goal: deliver a stable bottom taskbar experience for multi-display macOS users in a transparent and contributor-friendly codebase.

Mission

OpenBoringBar is an open-source implementation inspired by boringbar.app. Priority is reliability of core behavior before visual polish.

Product Direction

Keep focus on BoringBar-like core workflow:
- per-display bars
- running app visibility
- app switching
Optimize for real usability and stability first.
Build in public so contributors can inspect and extend behavior.

Technical Baseline

Platform: macOS 14+
Language: Swift 5
UI stack: SwiftUI + AppKit + ApplicationServices
Project generation: CocoaPods (pod install maintains project/workspace)

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.
