Side Effect Analyzer

What to do

Use this skill to run se-scan and turn scan output into an actionable audit report + fix plan.

Focus areas:

• CSS side effects (global selectors, conflicts, risky rules)
• Global variable pollution (accidental globals, window/prototype overrides)
• Global event listeners (missing cleanup, duplicate listeners, anonymous handlers)
• Dynamic DOM mutations (append/remove/insert/innerHTML, when enabled)

Workflow

1) Pick scan mode

• Built artifacts (recommended): when you have dist/ or want production-truth.
  • npx se-scan --dir dist
• Source entry: when you want to analyze from an entry and dependencies.
  • npx se-scan --entry src/index.ts
