What is xcode-testing-workflow?

A guide for testing Apple apps in Xcode, including automated interface tests, test plans, coverage checks, accessibility checks, and test diagnostics.

Use it to run and filter Swift or UI tests, check code coverage, validate accessibility, collect diagnostic files, and compare Debug and Release test behavior.

It helps developers choose the right test setup, run only the tests they need, and investigate failures or unreliable results in Xcode projects.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00081	$0.02560
Opus 5.5	$0.00032	$0.01024
Sonnet 5.5	$0.00016	$0.00512

Security

Grade A, and why

xcode-testing-workflow 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.

Xcode Testing Workflow

Purpose

Use this skill as the primary execution workflow for test-focused work in or around Xcode-managed projects and workspaces. Keep it focused on Swift Testing, XCTest, XCUITest, XCUIAutomation-oriented mechanics, code coverage, .xctestplan, destinations, launch arguments, interruption handling, attachments, accessibility-verification follow-through, Instruments profiling, xctrace trace capture, filters, retries, diagnostics, and test-specific Debug/Release validation instead of broad build/run or toolchain work. scripts/run-workflow.fsx is the runtime entrypoint for MCP-first test execution, official CLI fallback planning, and the remaining .pbxproj warning boundary when mutation enters project-file territory.

When To Use

Use this skill for Xcode test execution, test diagnosis, test filtering, retries, destination selection, and test-plan work.
Use this skill for Swift Testing, XCTest, XCUITest, XCUIAutomation-oriented mechanics, .xctestplan, flaky-test diagnosis, accessibility-verification follow-through, and test-only configuration validation.
Use this skill for Instruments and xctrace follow-through when performance-sensitive tests need Time Profiler, Metal System Trace, Allocations, VM Tracker, Points of Interest, signpost-aligned traces, or .trace artifact interpretation.
Use this skill for Xcode MCP operations and official Apple CLI fallback when the work is primarily about tests rather than build/run.
Use this skill when direct filesystem mutation around tests or test plans may be required.
Recommend xcode-coding-intelligence-workflow when the request is primarily about Xcode Intelligence setup, Xcode-hosted agents, external-agent access through xcrun mcpbridge, command/tool permissions, or Xcode-only agent configuration homes.
Do not use this skill as the default path for ordinary build, run, preview, archive, or general project-integrity work.
Recommend xcode-build-run-workflow when the task is primarily about build, run, previews, file membership, archives, toolchains, or guarded non-test mutation work.
Recommend explore-apple-swift-docs when the user needs Apple or Swift documentation lookup rather than execution work.
Recommend swift-package-testing-workflow when the task is package-first testing outside Xcode-managed execution.
Recommend bootstrap-xcode-workspace --operation align when an existing Apple product workspace needs managed guidance alignment rather than active engineering work.

Changes

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.
