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 edmundmiller/dotfiles at 5157d263dd.

    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 nix-rebuild skill allows an AI agent to trigger a rebuild of Nix derivations, effectively updating software packages and configurations managed by Nix. This includes building new versions of existing packages or creating entirely new ones based on defined configuration files. The skill ensures reproducible builds and consistent environments across different systems.

When to use it

  • Software updates: When you need to update a specific package in your Nix environment, triggering a rebuild ensures the latest version is installed.
  • Configuration changes: After modifying your configuration.nix or other Nix configuration files, a rebuild applies those changes.
  • Environment consistency: To guarantee consistent development environments across multiple machines by rebuilding from the same Nix configurations.
  • Automated deployments: As part of an automated deployment pipeline to ensure that all necessary components are built and deployed correctly.

Key capabilities

  • Triggers Nix derivation builds.
  • Updates software packages based on configuration files.
  • Ensures reproducible build environments.
  • Applies changes from configuration.nix.

Example prompts

  • "Rebuild my system with the latest version of Firefox."
  • "Apply the changes I made to my Nix configuration file."
  • “Build and install the package defined in /path/to/my/package.nix”

Tips & gotchas

  • Requires a working Nix environment to be set up beforehand.
  • The agent needs appropriate permissions to modify Nix configurations and trigger builds.
