Loupe CLAUDE.md

Loupe CLAUDE.md is an instructions file for Claude Code from smughead/Loupe. It costs 709 tokens per session, scanned A, original, MIT.

Project instructions for Loupe, a macOS accessibility inspection app built with Xcode and Swift Package Manager. They list commands for building and running its unit and user-interface tests.

In plain words
What is it for?
Use them to build Loupe, run all or selected tests, clean the project, and understand where its application and feature code live.
Why use it?
They prevent agents from opening the wrong project file or using incomplete checks.

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.

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

Loupe 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 6d 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.

Build Commands

# Build the app (from project root)
xcodebuild -workspace Loupe.xcworkspace -scheme Loupe -configuration Debug build

# Run all tests (unit + UI)
xcodebuild -workspace Loupe.xcworkspace -scheme Loupe -configuration Debug test

# Run only SPM package unit tests
xcodebuild -workspace Loupe.xcworkspace -scheme LoupeFeature test

# Run only UI tests
xcodebuild -workspace Loupe.xcworkspace -scheme Loupe -only-testing:LoupeUITests test

# Clean build
xcodebuild -workspace Loupe.xcworkspace -scheme Loupe clean

Open Loupe.xcworkspace in Xcode (not the .xcodeproj).

Architecture

This is a macOS accessibility inspection app using a Workspace + SPM Package architecture:

Loupe.xcworkspace
├── Loupe.xcodeproj        # App shell (minimal - just imports LoupeFeature)
│   └── Loupe/LoupeApp.swift   # @main entry point
└── LoupePackage           # SPM package (all feature code lives here)
    └── Sources/LoupeFeature/
        ├── ContentView.swift          # Main UI (NavigationSplitView)
        ├── Models/AXElementInfo.swift # Accessibility element data
        ├── Services/AccessibilityInspector.swift  # macOS Accessibility API wrapper
        └── Views/OverlayWindowController.swift    # Transparent inspection overlay

Core Components

AccessibilityInspector (@Observable, @MainActor): Wraps macOS Accessibility APIs (AXUIElement* functions). Manages permission checking, app enumeration, and element inspection at screen coordinates.

OverlayWindowController: Creates a transparent, borderless NSWindow that floats above the target app. Uses timer-based position tracking and a custom NSView for mouse event capture. Draws green dashed highlight rectangles around hovered elements.

AXElementInfo: Value type holding extracted accessibility metadata (role, identifier, title, value, frame, hierarchy path). Includes searchPatterns property that generates regex patterns for AI agents to locate elements in code.

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.
