When to use me

Use this skill when validating JavaScript files for syntax errors. Do not use this skill for PHP validation.

Step 1: Identify JavaScript files

Find all JS files in the project, excluding node_modules/, build/, and dist/ directories:

find . -name "*.js" -not -path "*/node_modules/*" -not -path "*/build/*" -not -path "*/dist/*"

Step 2: Check syntax

Use Node to check each JS file for syntax errors:

node --check <file>

• A file with valid syntax exits 0 with no output.
• A file with syntax errors prints the error with line number and exits non-zero.
• Fix any syntax errors found by editing the file, then re-check.

Rules

• Syntax only: This skill checks for JavaScript syntax errors. Do not run ESLint or other coding standard tools.
• Max 3 cycles: Run at most 3 fix-then-retest cycles per file. If issues remain after 3 cycles, report them as unresolved.
• Never modify business logic: Only fix syntax errors. Do not change how the code works.
• Report format: After testing, report results as:
  • PASS: No syntax errors
  • FAIL: List remaining errors with file, line, and message
