Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.
Pinned to a commit: passed

About this skill
What it does
This skill helps AI agents identify and avoid common mistakes in software testing strategies. It analyzes test suites to flag inefficient practices that reduce coverage or reliability without adding value.
When to use it
- Reviewing a legacy codebase with brittle, hard-to-maintain unit tests.
- Optimizing CI/CD pipelines by removing flaky or redundant test cases.
- Guiding junior developers on how to structure robust test scenarios.
- Auditing automated testing workflows for performance bottlenecks.
Key capabilities
- Detects over-testing and unnecessary duplication in test suites.
- Flags fragile tests that break due to minor code changes.
- Identifies missing edge cases or critical coverage gaps.
- Recommends refactoring steps to improve test maintainability.
Example prompts
- "Analyze this test suite and list the anti-patterns present."
- "Why are my unit tests failing frequently? Check for common testing mistakes."
- "How can I reduce the runtime of my test pipeline while keeping coverage high?"
Tips & gotchas
Ensure your test code is well-documented before analysis, as context improves detection accuracy. This skill focuses on patterns; it does not execute tests or fix bugs directly.
