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 | $0.00018 | $0.01743 |
| Opus 5.5 | $0.00007 | $0.00697 |
| Sonnet 5.5 | $0.00004 | $0.00349 |
| Haiku 4.5 | $0.00002 | $0.00174 |
Grade A, and why
test-xcode 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
97% identical to xcode-test — 7 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.

Xcode Test Command
<command_purpose>Build, install, and test iOS apps on the simulator using XcodeBuildMCP. Captures screenshots, logs, and verifies app behavior.</command_purpose>
Introduction
iOS QA Engineer specializing in simulator-based testing
This command tests iOS/macOS apps by:
- Building for simulator
- Installing and launching the app
- Taking screenshots of key screens
- Capturing console logs for errors
- Supporting human verification for external flows
Prerequisites
Main Tasks
0. Verify XcodeBuildMCP is Installed
<check_mcp_installed>
First, check if XcodeBuildMCP tools are available.
Try calling:
mcp__xcodebuildmcp__list_simulators({})
If the tool is not found or errors:
Tell the user:
**XcodeBuildMCP not installed**
Please install the XcodeBuildMCP server first:
\`\`\`bash
claude mcp add XcodeBuildMCP -- npx xcodebuildmcp@latest
\`\`\`
Then restart Claude Code and run `/xcode-test` again.
Do NOT proceed until XcodeBuildMCP is confirmed working.
</check_mcp_installed>
1. Discover Project and Scheme
<discover_project>
Find available projects:
mcp__xcodebuildmcp__discover_projs({})
List schemes for the project:
mcp__xcodebuildmcp__list_schemes({ project_path: "/path/to/Project.xcodeproj" })
If argument provided:
- Use the specified scheme name
- Or "current" to use the default/last-used scheme
</discover_project>
2. Boot Simulator
<boot_simulator>
List available simulators:
mcp__xcodebuildmcp__list_simulators({})
Boot preferred simulator (iPhone 15 Pro recommended):
mcp__xcodebuildmcp__boot_simulator({ simulator_id: "[uuid]" })
Wait for simulator to be ready: Check simulator state before proceeding with installation.
</boot_simulator>
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.

test-xcode is a command published in the GitHub repository tajmahal226/compound-engineering-plugin (4 stars, last pushed 7mo ago), licensed MIT. It adds 18 tokens to every session and 1,743 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 97% identical to xcode-test, differing in 7 lines, and is treated as a copy.
