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 mohitmishra786/low-level-dev-skills at bdc58472fa.

    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

linux-perf

What it does

This skill enables AI agents to interact with the Linux Performance Monitoring Framework (perf) to analyze system performance data. It allows for the execution of perf commands to profile applications, identify bottlenecks, and inspect hardware events directly from within an agent environment.

When to use it

  • Profiling a specific application binary to understand CPU usage patterns and hotspots.
  • Investigating system-wide latency issues by analyzing kernel tracepoints and hardware counters.
  • Generating performance reports for debugging slow-running services on Linux infrastructure.
  • Verifying the impact of code optimizations by comparing perf data before and after changes.

Key capabilities

  • Execute perf commands to record and analyze performance metrics.
  • Profile user-space applications to identify inefficient functions or threads.
  • Inspect hardware events and kernel-level performance counters.
  • Generate output suitable for further analysis or reporting within the agent workflow.

Example prompts

  • "Run a perf profile on /usr/bin/myapp with 10 seconds of recording time and display the top 5 functions by CPU usage."
  • "Analyze system performance using perf top to identify the most active kernel functions over the last minute."
  • "Generate a report showing hardware cache misses for the process with PID 1234 using perf stat."

Tips & gotchas

Ensure the target Linux environment has the linux-perf toolchain installed and that the user agent has sufficient permissions to access performance data. Be aware that running perf on production systems may incur slight overhead, so it is best suited for staging or development environments unless configured carefully.
