What it does

Fix Random CI Test Failure is an agent skill from dotnet/macios, published by the product's own GitHub organization. Investigate and fix flaky/random CI test failures in dotnet/macios. Trigger on GitHub issues describing intermittent test failures, CI postmortem issues, or when asked to fix a flaky test. Analyzes test code, identifies root causes (shared state, environment dependencies, race conditions), and applies fixes.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Failing and flaky tests. It works with .NET, GitHub, C# and iOS. The repository describes itself as: .NET for iOS, Mac Catalyst, macOS, and tvOS provide open-source bindings of the Apple SDKs for use with .NET managed languages such as C.

When your agent uses it

  • GitHub issues describing intermittent test failures
  • CI postmortem issues
  • Asked to fix a flaky test

Example prompts

  • “/fix-random-ci-test-failure”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Gather Failure Context
  2. Locate and Analyze the Test
  3. Identify Root Cause Category
  4. Apply the Fix
  5. If the Fix is Unclear
  6. Create the PR

What it can do on your machine

Read from SKILL.md and the folder at commit 354c2a6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Fix Random CI Test Failure loads about 1.3k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 631 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~84
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 631 words (~1,295 tokens).
