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 sentenz/skills at 0414902177.

    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

This skill allows AI agents to generate and execute C++ benchmark tests. It can measure the performance of code snippets, functions, or algorithms by timing their execution across multiple runs. The results are presented in a structured format suitable for analysis and comparison.

When to use it

  • Performance Optimization: Identify bottlenecks in existing C++ code by benchmarking different approaches.
  • Algorithm Selection: Compare the efficiency of various algorithms solving the same problem.
  • Code Review: Validate performance claims made during code reviews.
  • Hardware Evaluation: Assess the impact of hardware changes on C++ application performance.

Key capabilities

  • Generates C++ benchmark tests from natural language descriptions.
  • Executes generated benchmarks and collects timing data.
  • Provides structured output for analysis (e.g., average execution time, standard deviation).
  • Supports multiple runs to improve accuracy.

Example prompts

  • "Benchmark the performance of a quicksort implementation."
  • "Compare the speed of std::vector and std::list for inserting elements at the beginning."
  • “Create a benchmark that measures the time it takes to sort 10,000 integers.”

Tips & gotchas

  • The quality of the generated benchmarks depends on the clarity and specificity of the prompt. Provide sufficient context about the code or algorithms you want to test.
