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 terrylica/cc-skills at 3a1dc29965.

    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 Code Clone Assistant helps you identify and understand similar code snippets (clones) within a codebase to improve code quality and accelerate development. It leverages two tools, PMD CPD for detecting exact duplicates and Semgrep for finding patterns with variations. Combining these tools allows the skill to detect approximately 3x more potential DRY (Don't Repeat Yourself) violations than using either tool alone.

When to use it

  • Finding duplicate code in a codebase
  • Detecting DRY violations
  • Refactoring similar code patterns
  • Identifying copy-paste code

Key capabilities

  • Exact Duplicate Detection: Uses PMD CPD (v7.17.0+) to find exact copies of code.
  • Pattern-Based Detection: Employs Semgrep (v1.140.0+) to identify similar code patterns with variations, using custom rules.
  • Combined Analysis: Provides a combined analysis of results from both PMD CPD and Semgrep for more comprehensive clone detection.
  • Clone Type Identification: Differentiates between various clone types including exact copies (Type-1), near misses (Type-3) and those with renamed identifiers (Type-2).

Example prompts

  • "Find duplicate code in this Python file."
  • "Detect potential DRY violations in my project's codebase."
  • "Identify similar code patterns that I can refactor."

Tips & gotchas

  • Not all duplication is bad: The skill highlights the importance of checking for accepted exceptions before recommending refactoring, as some intentional copy-and-adapt patterns should be preserved (e.g., in generation-per-directory experiments or SQL templates).
  • Semgrep requires configuration: Semgrep uses a clone-rules.yaml file to define pattern matching rules.
  • Pro Semgrep needed for cross-file analysis: The Semgrep tool has limited scope, only allowing within/across files with the Pro version.
