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 trailofbits/skills at 82fe822625.

    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 AI agents to verify that sensitive data has been securely erased from memory using the zeroize crate. It provides programmatic access to audit mechanisms ensuring cryptographic secrets are overwritten rather than simply dropped, preventing recovery attacks on volatile storage.

When to use it

  • Verifying secure deletion of encryption keys before a system shutdown or reboot.
  • Auditing temporary buffers in high-security applications handling PII or financial data.
  • Implementing compliance checks for standards requiring proof of memory sanitization.
  • Testing the effectiveness of secret management libraries against memory scraping tools.

Key capabilities

  • Integration with Rust's zeroize crate for cryptographic zeroization.
  • Audit hooks to confirm when sensitive values are cleared from RAM.
  • Support for types implementing the Zeroize trait to ensure consistent behavior.
  • Prevention of data leakage during object destruction or scope exit.

Example prompts

  • "Audit this Rust function to ensure the API key is properly zeroized before the function returns."
  • "Verify that the zeroize-audit skill confirms memory sanitization for a session token stored in a local buffer."
  • "Generate a test case using zeroize-audit to prove that a secret string cannot be recovered after scope exit."

Tips & gotchas

Ensure your environment supports Rust 1.60+ as the underlying zeroize crate requires modern compiler features for safe memory handling. This skill is specific to Rust-based agents; it will not function within Python or JavaScript environments without a compatible runtime bridge.
