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 dauquangthanh/hanoi-rainbow at 0e2ebaea02.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

The jcl-migration-analyzer skill helps assess JCL (Job Control Language) code for compatibility with newer z/OS environments. It identifies potential issues arising from changes in system behavior or syntax, allowing for proactive adjustments during migration efforts. This ensures smoother transitions and reduces the risk of job failures post-migration.

When to use it

  • Planning a z/OS migration: Use this skill to evaluate existing JCL codebases before undertaking a major upgrade.
  • Troubleshooting job failures: If jobs fail after a system change, analyze the JCL with this tool to pinpoint compatibility issues.
  • Modernizing legacy applications: As part of an application modernization project, use it to understand and adapt JCL for contemporary environments.
  • Automating JCL review: Integrate into CI/CD pipelines to automatically check JCL changes for potential migration problems.

Key capabilities

  • JCL compatibility assessment
  • Identification of syntax errors related to z/OS versions
  • Detection of potentially problematic JCL statements
  • Analysis of system behavior impact on JCL execution

Example prompts

  • "Analyze this JCL code and identify any potential migration issues: [paste JCL code here]"
  • "What changes are needed in this JCL to run successfully on z/OS v2.3? [paste JCL code here]"
  • "Check this JCL for compatibility with the latest z/OS release."

Tips & gotchas

The skill's accuracy depends on providing complete and accurate JCL code. It is not a substitute for thorough testing in a representative target environment after any migration or system change.
