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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.00719 |
| Opus 5.5 | $0.00016 | $0.00288 |
| Sonnet 5.5 | $0.00008 | $0.00144 |
| Haiku 4.5 | $0.00004 | $0.00072 |
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 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.
This is a copy
86% identical to ios-debugger-agent — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
Core Workflow
Follow this sequence unless the user asks for a narrower action.
1) Discover the booted simulator
- Call
mcp__XcodeBuildMCP__list_simsand select the simulator with stateBooted. - 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-defaultswith:projectPathorworkspacePath(whichever the repo uses)schemefor the current appsimulatorIdfrom 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_uiormcp__XcodeBuildMCP__screenshotbefore 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:
mcp__XcodeBuildMCP__get_sim_app_pathmcp__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_uibefore tapping or swiping. - Tap:
mcp__XcodeBuildMCP__tap(preferidorlabel; use coordinates only if needed). - Type:
mcp__XcodeBuildMCP__type_textafter focusing a field. - Gestures:
mcp__XcodeBuildMCP__gesturefor common scrolls and edge swipes. - Screenshot:
mcp__XcodeBuildMCP__screenshotfor visual confirmation.
Logs & Console Output
- Start logs:
mcp__XcodeBuildMCP__start_sim_log_capwith the app bundle id. - Stop logs:
mcp__XcodeBuildMCP__stop_sim_log_capand summarize important lines. - For console output, set
captureConsole: trueand relaunch if required.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 flaqai/ios-application-development-skills (5 stars, last pushed 2mo ago), licensed MIT. It adds 40 tokens to every session and 719 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 86% identical to ios-debugger-agent, differing in 2 lines, and is treated as a copy.
Other skills, from other repositories
debug
Investigate a failure, regression or incorrect result in an integration or application, even before it can be reproduced. Use for diagnosis and repair; follow incident authority for live mitigation.
rescue
Triage an outage, loss of stakeholder trust or a failing engagement direction. Use for urgent recovery; distinguish diagnosis from authorized production mitigation.
mobile-debugging
Remote JavaScript console and debugging on mobile. Use for phone/tablet console errors, responsive testing, Eruda, and vConsole.
flutter-widget-architect
Architects Flutter widget trees and Riverpod or Bloc state so rebuilds are scoped, build() stays pure, and const widgets skip recomposition. Use when someone asks "why is my Flutter screen janky", "should I use Riverpod or Bloc", "my whole page rebuilds when one field changes", or is building or refactoring Flutter…
gcd-operations
Use for iOS/macOS concurrency problems involving dispatch queues, locks, or thread safety. Triggers on: deadlocks (sync on main, nested sync, ABBA lock ordering), thread explosion from too many DispatchQueue.global() calls, data races flagged by Thread Sanitizer (TSan), DispatchGroup enter/leave imbalance…
trace-fix
Evidence-gated debugging protocol for iOS/macOS and Swift apps: trace the execution path, locate the exact divergence, prove the root cause, and only then fix. Use for any bug where code compiles but behaves wrongly (hangs, freezes, wrong or missing data, silent failures, intermittent issues) and for crashes…
