blitz-mac CLAUDE.md

Repository instructions for building, testing, debugging, and packaging Blitz, a native macOS app for iOS development.

In plain words
What is it for?
Use them to build the app, run all or selected Swift tests, fetch its pinned dependency, create an installer, or prepare a release.
Why use it?
They give coding agents the project-specific commands and structure needed to make changes without guessing how the app is assembled or tested.

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

blitz-mac 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 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.

Architecture

Blitz is a native macOS SwiftUI app (requires macOS 14+) for iOS development. It provides simulator management, screen capture, App Store Connect integration, and an MCP server for Claude Code integration. Built with Swift Package Manager (no Xcode project). Source bundling also depends on the pinned ASC helper submodule in deps/App-Store-Connect-CLI-helper and a local Go toolchain.

Single-target structure

All Swift source lives in src/. Core types (process execution, simulator control, device interaction, project metadata) live alongside UI, services, and the MCP server in one executable target.

App State

Single AppState (@Observable) object at AppState.swift holds all app state. Child observable managers:

  • ProjectManager — project list and loading
  • SimulatorManager — simulator lifecycle (boot/shutdown via SimctlClient)
  • SimulatorStreamManager — screen capture via ScreenCaptureKit + Metal rendering
  • ASCManager — App Store Connect API integration
  • ProjectSetupManager — project scaffolding for different project types

Navigation

AppTab enum defines all tabs, grouped into Build (simulator, tests, assets), Release (ASC tabs), Insights, TestFlight, and Settings. ContentView uses NavigationSplitView with SidebarView + DetailView that switches on appState.activeTab.

MCP Server (Claude Code Integration)

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.
