React Audit Grep Patterns

SkillAI & models

Lets your agent scan React code with grep commands to find outdated APIs before upgrading to React 18 or 19.

Instructions available. Your AI can read the instructions. Execution depends on the setup they require.

Add ahel to your AI once: Claude, ChatGPT, Cursor, Claude Code or Codex. Then ask it to use this.

Then ask your AI: use the React Audit Grep Patterns skill

About this skill

Provides the complete, verified grep scan command library for auditing React codebases before a React 18.3.1 or React 19 upgrade. Use this skill whenever running a migration audit - for both the react18-auditor and react19-auditor agents. Contains every grep pattern needed to find deprecated APIs, r

What this skill tells your AI

The instructions your AI receives, as published by github/awesome-copilot in skills/react-audit-grep-patterns/SKILL.md and read by ahel’s review.

Complete scan command library for React 18.3.1 and React 19 migration audits.

Usage

Read the relevant section for your target:

  • references/react18-scans.md - all scans for React 16/17 → 18.3.1 audit
  • references/react19-scans.md - all scans for React 18 → 19 audit
  • references/test-scans.md - test file specific scans (used by both auditors)
  • references/dep-scans.md - dependency and peer conflict scans

Base Patterns Used Across All Scans

# Standard flags used throughout:
# -r = recursive
# -n = show line numbers
# -l = show filenames only (for counting affected files)
# --include="*.js" --include="*.jsx" = JS/JSX files only
# | grep -v "\.test\.\|\.spec\.\|__tests__" = exclude test files
# | grep -v "node_modules" = safety (usually handled by not scanning node_modules)
# 2>/dev/null = suppress "no files found" errors

# Source files only (exclude tests):
SRC_FLAGS='--include="*.js" --include="*.jsx"'
EXCLUDE_TESTS='grep -v "\.test\.\|\.spec\.\|__tests__"'

# Test files only:
TEST_FLAGS='--include="*.test.js" --include="*.test.jsx" --include="*.spec.js" --include="*.spec.jsx"'
