ios-debugger-agent

ios-debugger-agent is a skill for Claude Code, Codex from beel-collab/presets.dev. It costs 18 tokens per session (840 once invoked), scanned A, a copy of ios-debugger-agent, MIT.

A debugging workflow for running an iOS project on a booted simulator, interacting with its interface, and collecting logs with XcodeBuildMCP. An iOS simulator is a computer-based test device for iPhone and iPad apps.

In plain words
What is it for?
Use it to build and launch an iOS app on a simulator, inspect the interface, capture screenshots, interact with controls, and read runtime logs.
Why use it?
It helps reproduce runtime problems and inspect what the app does while it is running, instead of relying only on source-code review.

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 5d 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.

iOS Debugger Agent

Overview

Use XcodeBuildMCP to build and run the current project scheme on a booted iOS simulator, interact with the UI, and capture logs. Prefer the MCP tools for simulator control, logs, and view inspection.

When to Use

  • When the user asks to run, debug, or inspect an iOS app on a simulator.
  • When you need simulator UI interaction, screenshots, or runtime logs via XcodeBuildMCP.

Core Workflow

Follow this sequence unless the user asks for a narrower action.

1) Discover the booted simulator

  • Call mcp__XcodeBuildMCP__list_sims and select the simulator with state Booted.
  • If none are booted, ask the user to boot one (do not boot automatically unless asked).

2) Set session defaults

  • Call mcp__XcodeBuildMCP__session-set-defaults with:
    • projectPath or workspacePath (whichever the repo uses)
    • scheme for the current app
    • simulatorId from the booted device
    • Optional: configuration: "Debug", useLatestOS: true

3) Build + run (when requested)

  • Call mcp__XcodeBuildMCP__build_run_sim.
  • If the build fails, check the error output and retry (optionally with preferXcodebuild: true) or escalate to the user before attempting any UI interaction.
  • After a successful build, verify the app launched by calling mcp__XcodeBuildMCP__describe_ui or mcp__XcodeBuildMCP__screenshot before proceeding to UI interaction.
  • If the app is already built and only launch is requested, use mcp__XcodeBuildMCP__launch_app_sim.
  • If bundle id is unknown:
    1. mcp__XcodeBuildMCP__get_sim_app_path
    2. mcp__XcodeBuildMCP__get_app_bundle_id

UI Interaction & Debugging

Use these when asked to inspect or interact with the running app.

  • Describe UI: mcp__XcodeBuildMCP__describe_ui before tapping or swiping.
  • Tap: mcp__XcodeBuildMCP__tap (prefer id or label; use coordinates only if needed).
  • Type: mcp__XcodeBuildMCP__type_text after focusing a field.
  • Gestures: mcp__XcodeBuildMCP__gesture for common scrolls and edge swipes.
  • Screenshot: mcp__XcodeBuildMCP__screenshot for visual confirmation.

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.
