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

simpod 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 1mo 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

Simpod streams and remotely controls booted iOS Simulators from a browser, terminal, or AI agent. A Dart CLI spawns one native Swift helper per simulator; the helper captures the framebuffer, streams H.264 (MJPEG fallback), injects touch/keyboard input, and exposes the accessibility tree. Requires macOS 14+, Xcode CLT (xcrun simctl), and a booted simulator.

Commands

flutter pub get                      # resolve the Dart workspace (run from repo root)

# Tests (run inside the package directory)
cd packages/simpod && dart test      # CLI tests
cd packages/simpod_core && dart test # shared-model tests
dart test test/services/helper_manager_test.dart          # single file
dart test -N "name substring"                             # single test by name

dart analyze packages/simpod packages/simpod_core          # lint (what CI runs)

# Native Swift helper
swift build --package-path packages/native                 # build
swift test --package-path packages/native                  # tests

# Flutter web dashboard
cd packages/simpod_client && flutter build web --wasm --release

./build.sh                           # full standalone binary -> build/simpod

For development you usually don't need ./build.sh: run dart run bin/simpod.dart from packages/simpod. When embedded assets are absent it falls back to source paths — the helper binary at packages/simpod/lib/bin/simpod-helper-bin (produced by swift build -c release + copy, see build.sh steps 1–2) and the dashboard at packages/simpod_client/build/web.

Architecture

Dart workspace (pubspec.yaml at root) with three Dart packages plus a SwiftPM package:

  • packages/simpod — the CLI (bin/simpod.dart, commands in lib/src/commands/) and the preview HTTP server (lib/src/server/simpod_http_server.dart, shelf_router). Device discovery and control shell out to xcrun simctl (lib/src/devices/). SimpodHelperManager (lib/src/services/helper_manager.dart) spawns/kills helper processes; SimpodSessionManager persists per-udid session files (pid, port, urls, access token) so short-lived CLI commands can find running helpers.
  • packages/native — Swift 6 executable simpod-helper-bin (Hummingbird HTTP/WS server, one process per simulator). Framebuffer capture via IOSurface, H.264 via VideoToolbox, JPEG encode, HID injection through private CoreSimulator/SimulatorKit interfaces, accessibility bridge, and device-bezel/chrome rendering.
  • packages/simpod_client — Flutter web dashboard. Decodes H.264 with WebCodecs VideoDecoder (lib/core/utils/avcc_stream_renderer.dart), falls back to MJPEG.
  • packages/simpod_core — models and protocol enums shared by CLI and client (DeviceInfo, SimpodSession, AXNode, orientation/touch-edge/key-event types).

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.
