Tool Ast Grep Rules

Checked
heyvhuang·vlatest·backend·MIT

This skill uses AST and grep rules to efficiently search and extract specific code elements from large files, streamlining development tasks.

Repository

Showing Claude Code. One command installs this skill into any of the agents below.

  1. 1

    Run this in your project

    terminal
    $ npx skills add heyvhuang/ship-faster --skill tool-ast-grep-rules -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

Install target

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 heyvhuang/ship-faster at 64047d24e0.

    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 install and utilize ast-grep rules, which are pattern-matching configurations designed to analyze code structure rather than just text. By applying these rules, agents can automatically detect specific coding patterns, enforce style guidelines, and identify potential issues across large codebases efficiently.

When to use it

  • Enforcing consistent coding standards and style guides across a monorepo or multi-language project.
  • Automatically refactoring legacy code by identifying deprecated patterns or anti-patterns defined in rules.
  • Integrating into CI/CD pipelines to block merges that violate specific structural constraints.
  • Auditing third-party dependencies for known vulnerability signatures or insecure coding practices.

Key capabilities

  • Parses and analyzes source code based on Abstract Syntax Tree (AST) structures.
  • Supports multiple programming languages with dedicated parsers.
  • Allows custom rule definitions for complex logic checks beyond simple regex.
  • Provides actionable feedback with file locations and specific line numbers.

Example prompts

  • "Install the tool-ast-grep-rules skill and scan our React frontend repository for unused prop patterns."
  • "Create a new ast-grep rule to detect any function calls missing error handling in our Python backend services."
  • "Run an audit using installed rules to find instances of hardcoded secrets in configuration files across the entire project."

Tips & gotchas

Ensure your codebase has compatible parsers for the languages you intend to analyze, as unsupported syntax may lead to incomplete results. For best performance on large repositories, consider running scans incrementally or filtering by specific file extensions before applying heavy rulesets.
