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.

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 cobol-migration-analyzer skill analyzes COBOL code to identify potential migration challenges and complexities. It assesses the codebase for dependencies, data structures, and logic that might require significant refactoring during a modernization effort. The tool provides insights into areas of high risk and suggests strategies for successful migration.

When to use it

  • Planning a COBOL Modernization: Before embarking on a large-scale COBOL rewrite or replacement project.
  • Assessing Migration Effort: To estimate the time, resources, and potential risks associated with migrating a specific COBOL application.
  • Identifying Code Dependencies: When needing to understand how different parts of a COBOL system interact before making changes.
  • Evaluating Refactoring Options: To determine the best approach for modernizing individual components or modules within a larger COBOL application.

Key capabilities

  • Dependency analysis
  • Data structure assessment
  • Logic complexity evaluation
  • Risk identification
  • Migration strategy suggestions

Example prompts

  • "Analyze this COBOL code snippet and identify potential migration challenges." (followed by the code)
  • "What are the key dependencies in this COBOL program?"
  • "Assess the complexity of this COBOL data structure for migration purposes."

Tips & gotchas

The accuracy of the analysis depends on the completeness and quality of the provided COBOL code. Ensure that all relevant files and modules are included for a comprehensive assessment.
