ios-debugger-agent

ios-debugger-agent is a skill for Claude Code, Codex from patrickserrano/lacquer. It costs 42 tokens per session (1,636 once invoked), scanned A, original, MIT.

A skill for building, running, and investigating an iOS app inside a simulator, a software version of an Apple device on a computer.

In plain words
What is it for?
Use it to reproduce runtime problems, interact with the simulated app, capture logs, and diagnose behaviour in an Xcode project.
Why use it?
It brings app installation, launching, simulator interaction, and runtime log collection into one debugging workflow.

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

ios-debugger-agent 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 yesterday.

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.

iOS Debugger Agent

Build and run iOS projects on a booted simulator, interact with the UI, and capture logs for debugging — via the flowdeck skill, which is this lacquer's canonical source of truth for exact FlowDeck syntax. This skill is a thin, scenario-specific wrapper around it, not a competing source of commands. If a command below errors or you're unsure of a flag, consult flowdeck's resources/ docs or run flowdeck <command> --help rather than guessing — never fall back to xcrun/simctl/xcodebuild.

Overview

FlowDeck ties build, install, and launch together (flowdeck run), and streams logs from the running app rather than querying the OS unified log. There is no need to discover DerivedData paths, hand-construct xcodebuild destinations, or spawn log stream predicates — FlowDeck's config-first workflow and app-tracking model replace all of that.

Prerequisites

  • FlowDeck CLI installed (flowdeck --version)
  • Project with .xcodeproj or .xcworkspace
  • A saved FlowDeck config, or enough context to create one (flowdeck context --json)

Core Workflow

1) Check for a saved config first

flowdeck config get --json

If a config exists, use bare commands (flowdeck build, flowdeck run, etc.) for the rest of this workflow. If not, discover and create one:

flowdeck context --json
flowdeck config set -w <workspace> -s <scheme> -S "<simulator>"

2) Discover the booted simulator (if you need a specific one)

flowdeck simulator list --json

Check each entry's state field for "Booted". If none are booted and you need a specific device, boot one by UDID (boot takes a UDID, not a name):

flowdeck simulator boot <udid>

3) Build the project

flowdeck build

Add -w <workspace> -s <scheme> -S "<simulator>" only if no config is saved and you're not overriding it.

4) Install and launch the app

flowdeck run

This builds, installs, and launches in one step, returning an App ID. To launch an existing build without rebuilding:

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.

ios-debugger-agent is a skill published in the GitHub repository patrickserrano/lacquer (3 stars, last pushed today), licensed MIT. It adds 42 tokens to every session and 1,636 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
