test-flakiness

test-flakiness is a skill for Claude Code from IdoCohen560/claude-unity-game-studio. It costs 59 tokens per session (1,973 once invoked), scanned A, a copy of test-flakiness, MIT.

A checker for flaky tests, which are tests that pass and fail unpredictably without a code change. It reads CI logs or test history, measures intermittent failures, and keeps a registry of known flaky tests.

In plain words
What is it for?
Use it to analyse a CI log, scan available CI logs, review quarantined tests, and get guidance on fixing or isolating flaky tests.
Why use it?
It helps separate real regressions from unreliable tests so failed CI runs are not routinely ignored.

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

test-flakiness 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 6d 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.

Test Flakiness Detection

A flaky test is one that sometimes passes and sometimes fails without any code change. Flaky tests are worse than no tests in some ways — they train the team to ignore red CI runs, masking genuine failures. This skill identifies them, explains likely causes, and recommends whether to quarantine or fix each one.

Output: Updated tests/regression-suite.md quarantine section + optional production/qa/flakiness-report-[date].md

When to run:

  • Polish phase (tests have had many runs; statistical signal is reliable)
  • When developers start dismissing CI failures as "probably flaky"
  • After /regression-suite identifies quarantined tests that need diagnosis

1. Parse Arguments

Modes:

  • /test-flakiness [ci-log-path] — analyse a specific CI run log file
  • /test-flakiness scan — scan all available CI logs in .github/ or standard log output directories
  • /test-flakiness registry — read existing regression-suite.md quarantine section and provide remediation guidance for already-known flaky tests
  • No argument — auto-detect: run scan if CI logs are accessible, else registry

2. Locate CI Log Data

Option A — GitHub Actions (preferred)

Check for test result artifacts:

ls -t .github/ 2>/dev/null
ls -t test-results/ 2>/dev/null

For Godot projects: GdUnit4 outputs XML results compatible with JUnit format. Check test-results/ for .xml files.

For Unity projects: game-ci test runner outputs NUnit XML to test-results/ by default.

For Unreal projects: automation logs go to Saved/Logs/. Grep for Result: Success and Result: Fail patterns.

Option B — Local log files

If a path argument is provided, read that file directly.

Option C — No log data available

If no logs found:

"No CI log data found. To detect flaky tests, this skill needs test result history from multiple runs. Options:

  1. Run the test suite at least 3 times and collect the output logs
  2. Check CI pipeline output and save a log to test-results/
  3. Run /test-flakiness registry to review tests already flagged as flaky in tests/regression-suite.md"

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.
