openusage: Skill for Claude Code

.agents/skills/macos-test-triage/SKILL.md

macos-test-triage is a skill for Claude Code, Codex from robinebers/openusage. It costs 36 tokens per session (362 once invoked), scanned A, original, MIT.

A guide for investigating failed macOS tests in Xcode projects and Swift packages.

In plain words
What is it for?
It helps select the right test command, rerun focused cases, classify failures such as crashes or assertion errors, and report the next useful diagnostic step.
Why use it?
It narrows failures to the smallest useful test scope and distinguishes code regressions from build, environment, timing, entitlement, or setup problems.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is robinebers/openusage's own configuration. It tells Claude Code and Codex how to work on openusage itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything openusage configures →

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

macos-test-triage 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 2mo 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.

What it actually says

Test Triage

Quick Start

Use this skill to run the smallest meaningful test scope first, classify failures precisely, and avoid treating every test failure like a product bug.

Workflow

  1. Detect the test harness.

    • Use xcodebuild test for Xcode-based projects.
    • Use swift test for SwiftPM packages.

  2. Narrow the scope.

    • If the user gave a target, product, or test filter, use it.
    • If not, prefer the smallest likely failing target before a full suite.

  3. Classify the result.

    • Build failure
    • Assertion failure
    • Crash or signal
    • Async timing or flake
    • Environment or fixture setup issue
    • Missing entitlement or host app issue

  4. Rerun intelligently.

    • Use focused reruns when a specific case fails.
    • Avoid burning time on full-suite reruns without new information.

  5. Summarize clearly.

    • What command ran
    • Which tests failed
    • What kind of failure it was
    • The best next proof step or fix path

Guardrails

  • Distinguish compilation failures from test execution failures.
  • Call out when a test appears to assume iOS-only or simulator-only behavior.
  • Mark likely flakes as such instead of overstating confidence.

Output Expectations

Provide:

  • the command used
  • the smallest failing scope
  • the top failure category
  • a concise explanation of the likely cause
  • the next rerun or fix step

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.
