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 gmh5225/awesome-llvm-security at dad2f21a55.

    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 enables dynamic instrumentation, allowing for runtime modification and analysis of code. It facilitates the insertion of probes or hooks into a running program to collect data or alter behavior without requiring recompilation. This capability is particularly useful for security research, debugging, and performance monitoring.

When to use it

  • Security Auditing: Analyze potentially vulnerable code paths in real-time by injecting custom checks.
  • Debugging Complex Systems: Insert breakpoints and logging statements into a running application without restarting or modifying source code.
  • Performance Profiling: Gather detailed performance metrics at specific points within a program's execution flow.
  • Runtime Code Modification: Dynamically alter the behavior of a program based on runtime conditions, such as applying patches or enabling/disabling features.

Key capabilities

  • Runtime code modification
  • Probe insertion
  • Hook injection
  • Data collection at runtime
  • Behavioral analysis

Example prompts

  • "Insert a probe before this function call to log its arguments."
  • "Dynamically patch this instruction to redirect execution flow."
  • "Instrument the program to collect stack traces on error conditions."

Tips & gotchas

This skill requires a deep understanding of the target architecture and programming language. Incorrect instrumentation can lead to instability or unexpected behavior in the running application.
