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 thebushidocollective/han at 19caa51d5f.

    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 gracefully handle errors encountered when executing shell commands. It provides mechanisms for capturing error codes, interpreting error messages, and taking appropriate actions based on these errors – such as retrying a command or escalating an issue. The agent can also report the nature of the error back to the user or another system.

When to use it

  • Automated deployments: When deploying applications via scripts, this skill ensures that failures are detected and handled appropriately instead of silently failing.
  • System administration tasks: Automating server maintenance or configuration changes requires robust error handling to prevent unintended consequences.
  • Data processing pipelines: When running a series of shell commands to process data, the skill can ensure data integrity by detecting and correcting errors along the way.
  • Scripted backups: Automated backup scripts need to reliably report failures so that issues can be addressed promptly.

Key capabilities

  • Error code capture
  • Error message interpretation
  • Conditional command retries
  • Error reporting

Example prompts

  • "Run this script and handle any errors, retrying once if it fails."
  • "Execute the backup command and report any error codes to me."
  • "Check if the server is reachable using SSH; if not, log the error and alert an administrator."

Tips & gotchas

This skill assumes a basic understanding of shell scripting and common error codes. The agent's effectiveness depends on well-defined retry logic and appropriate error reporting mechanisms being configured.
