What is barkeep AGENTS.md?

A set of instructions for coding agents working on Barkeep, a native macOS menu-bar app for managing visible and hidden menu-bar items.

Use it when changing the macOS app lifecycle, menu-bar controls, item visibility, search, accessibility-based moving, settings, updates, or user-facing documentation.

It records product behavior, security requirements, architecture, and documentation rules so changes do not break how the app protects or organizes items.

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	$0.01560	$0.01560
Opus 5	$0.00780	$0.00780
Sonnet 5	$0.00312	$0.00312
Haiku 4.5	$0.00156	$0.00156

Security

Grade A, and why

barkeep 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 2d 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.

Agent notes

Barkeep is a local native macOS menu bar manager. It uses Swift 6, an AppKit lifecycle and status bar, SwiftUI views, XcodeGen, and Sparkle.

Product rules

Every item belongs to Always visible, Hidden, or Always hidden.
Click reveals Hidden. Option-click reveals all items. Right-click opens the command menu.
Command-Backslash toggles items. Command-Shift-Space opens search.
Only a direct item-section action can post a Command-drag.
A move must use fresh Accessibility data and must pass a second scan before state is saved.
Launch, wake, display events, app events, timers, and updates must never move an item.
Touch ID or Mac password protection applies to all reveal paths, including search and triggers.
Barkeep uses no account, telemetry, cloud sync, or Screen Recording.
Saved settings, rules, and profiles stay under Application Support.
Update failure cannot block app launch or the menu bar engine.

Read docs/PRODUCT.md before you change visible behavior. Keep README.md and docs/TROUBLESHOOTING.md accurate when a user-facing feature changes.

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.
