Install target

Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

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

    Scanned armanzeroeight/fastagent-plugins at 61b61a99e6.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The armanzeroeight-test-coverage-analyzer skill analyzes test coverage reports to identify areas of code with insufficient testing. It provides insights into the percentage of lines covered, highlighting gaps that may indicate potential bugs or vulnerabilities. This allows for targeted improvements in testing strategies and increased confidence in software quality.

When to use it

  • Identify Test Gaps: Use this skill when you need to quickly understand which parts of your codebase have inadequate test coverage.
  • Improve Code Quality: Integrate this into a CI/CD pipeline to automatically assess code changes for sufficient testing before deployment.
  • Refactor with Confidence: Before undertaking significant refactoring, use the analyzer to establish a baseline and ensure new changes maintain adequate coverage.

Key capabilities

  • Analyzes test coverage reports
  • Identifies areas of insufficient test coverage
  • Provides percentage of lines covered

Example prompts

  • "Analyze this test coverage report: [paste report content]"
  • "What parts of my code are not adequately tested based on this report?"
  • "Give me a summary of the test coverage for this project."

Tips & gotchas

The skill requires a valid test coverage report as input, typically in formats like Cobertura or similar. Ensure the report is correctly formatted and accessible to the AI agent.
